What is Cloud Misconfiguration and How Can You Avoid It?

The increased usage of the cloud, intended to promote company agility and resilience, has recently increased cyber risks. It does not follow, however, that choosing to adopt cloud-based-hosted environments automatically increases an organization’s vulnerability to a cyberattack. Because specific security solutions aren’t designed to secure cloud-hosted environments, securing a cloud environment requires a different security strategy than securing on-premises infrastructures.

IaaS (infrastructure-as-a-service) solutions are becoming increasingly popular among businesses for their IT operations. According to Gartner, by 2022, double the number of corporate entities using cloud-managed products 2018 will be using them.

According to the NSA, cloud misconfiguration is the most significant vulnerability in a cloud security environment. Although these risks are frequently modest in sophistication, the occurrence of cloud misconfiguration problems is typically through the sky. In other words, 99% of businesses will have cloud misconfigurations that they are entirely unaware of.

What is Cloud Misconfiguration?

Any flaws, defects, or holes in your cloud setup that could put you in danger are called cloud misconfiguration. This cloud security risk may manifest as insider threats, cloud breaches, data breaches, insider threats, or bad external actors who use your network’s weaknesses to their advantage. This serious compliance risk might appear in a variety of ways, including:

• Granting public access to storage buckets;
• Unknowingly disclosing unencrypted data to the public internet without the necessary authentication in place;
• Improper network functionality generation;
• Exposing data saved in the cloud to all system users and storing encryption keys and passwords in publicly accessible repositories.

It can be either malicious or accidental.

• Malicious cloud misconfiguration is when someone deliberately sets up their cloud server to access someone else’s product or data. This is often done by hackers who want to steal information or even cause physical harm.
• Accidental cloud misconfiguration happens when a company puts its information on public clouds and does not secure it properly. This can happen because a company doesn’t understand its responsibilities in this respect or anticipate how much work would be required to ensure its data once it is moved into the cloud.

Leading Causes of Misconfigured Cloud Infrastructures

Most misconfigurations are caused by human error and elements like overly complicated infrastructure or inadequate knowledge of security procedures.

Malicious Insiders

While it is difficult to know who is responsible for a breach, the most common culprits are malicious insiders who have gained access to user credentials and have tried to use them to launch attacks on the cloud environment. As a result, users are often forced to change their passwords or reset their accounts’ entire passwords.

Denial of Service Attacks (DoS)

A denial of service attack occurs when an attacker tries to overload a system with data requests so that it cannot service legitimate requests from users or other applications. This can result in lost productivity, disrupted operations, and an inability to process payments, which can cause financial losses for companies with cloud-based eCommerce platforms.

Overly Complex Infrastructure

Cloud infrastructure typically consists of multiple components such as servers, storage systems, networks, and firewalls that work together to provide cloud services across various geographic locations worldwide. IT professionals may become susceptible to attack by hackers or malware distributors seeking entry into company systems when these components are not correctly configured or managed by IT professionals.

Unauthorized Access

An unauthorized individual can access your cloud infrastructure and wreak havoc on the AWS environment. In the case of a malicious actor, the consequences can be devastating to business operations, financial security, or even human lives.

Insufficient Understanding of Security

When creating and managing apps and infrastructure, the majority of developers and DevOps teams do not place a high priority on security. These teams primarily concentrate on ensuring that services perform properly and offer users functionality.

When selecting members for your development team, consider security. Ensure they comprehend crucial ideas like application hardening, least privilege, and encryption at rest.

How to Avoid Cloud Misconfiguration?

Here are some tips to avoid cloud misconfiguration:

Implement Log Tracking

The first step to avoiding cloud misconfiguration is to implement logging and monitoring. When a cloud service is misconfigured, it’s often difficult to identify what exactly went wrong. The best way to catch this type of issue is by using a detailed logging and monitoring system. You can determine the root cause of any misconfiguration incidents by tracking changes.

Add Layered Security

Layer testing is another way to prevent cloud misconfiguration issues. Layer testing involves placing multiple checks on your application before deploying it in production. For example, if you are deploying an application that requires authentication, you will use one layer of testing for authentication and another layer for authorization. This way, if something goes wrong during authentication, it does not affect approval.

Automate Configuration and Security Checks

Automation is an integral part of cloud security. A data breach can occur if the same settings are used in multiple environments. Automating the deployment of your infrastructure helps you eliminate this risk.

Simplify Your Environments

If you have multiple environments for your applications, then it’s essential to simplify them as much as possible. This is because every domain has different requirements and limitations. For example, if you have an internal production environment and an external staging environment, having two separate configurations will complicate things further down the line.

Document Everything

If you’re using cloud-based services, then they will require your information. So, ensure you have all the documentation ready before moving to the next step. This will help you in case of an issue with your service or a security breach.

Scan for Vulnerabilities

A scan will check whether your server has known security issues that could allow hackers to access it. If there are any vulnerabilities, ensure you fix them as soon as possible by following best practices such as patching software, updating third-party libraries, or installing anti-virus software on your server.

Adopt a DevSecOps Culture

The process of development and deployment has long neglected security. A DevSecOps culture is created by combining awareness and attention to growth, safety, and operations. This culture makes incorporating security as a crucial component of application design and development more accessible.

It helps to build security into your application’s framework to have competent security resources on your design and development teams. Avoiding issues in the first place will prevent the hassle of dealing with them afterward.

Conclusion

Misconfiguration issues are ultimately nothing new; they have moved to the cloud with the applications. Your organization’s ability to lower its cyber risk and the likelihood of being a victim of a cloud-misconfiguration-based breach will improve the more cloud security automation you can deploy in combination with human-backed services. Managing your security threats inside your expanding list of cloud services is crucial as cloud usage keeps accelerating. A significant data leak can result from a single configuration error.

Managed Services vs. Cloud Computing: What’s the Difference?

Suppose you’re a CIO of a company or just an employee. In that case, it’s likely that sooner or later, you will have to deal with two opposing forces: on the one hand, the demands of your organization and the increasing need for agility, and on the other, your team’s inability to manage everything in a digital world. These two factors often lead to a choice between having a managed services contract, which relieves some pressure from your technical department by allowing them to use third-party companies instead of managing services themselves or going all-in with cloud computing.

Managed services and cloud computing can help businesses streamline operations, automate processes, and make data-driven decisions. They also have several things in common that make understanding the differences between managed services and cloud computing more accessible. Managed services and cloud computing are two popular ways organizations outsource their technology needs. Managed services refer to outsourcing day-to-day technology management, including data management systems and IT infrastructure management. On the other hand, cloud computing refers to using cloud-based services to store and access data securely.

Whether you’re a business looking to cut costs or develop an online presence, knowing what these services are and how they can benefit your organization is essential. Read on to learn more about the similarities and differences between managed services and cloud computing.

What is a Managed Service?

Managed services refer to a type of outsourcing where a company owns the technology and staff of another company, but not the business process or the customer relationship. A managed service provider (MSP) offers customers various types of managed services, governed by a service level agreement (SLA). This agreement outlines the expected level of service, including response time, issue resolution, and performance metrics.

One popular type of managed service is data management. This involves the storage, retrieval, and security of customer data. Another type of managed service is information technology services, which include the management of an organization’s technology infrastructure, such as servers, networks, and software applications.

Protected Harbor offers clients various managed services, including data management, cloud computing, migration, and information technology services. We work with our clients to develop customized SLAs that meet their specific needs and provide them with peace of mind knowing that their technology and data are in good hands.

There are several reasons why companies choose to partner with us for their managed services needs. One of the main reasons is our expertise in data management, which helps clients improve their data security and compliance. We also offer various managed services, including cloud-based solutions, which provide our clients the flexibility and scalability they need to grow their businesses.

For example, a hosting company outsources the management of its infrastructure to a third-party company. The customer’s website is hosted on the managed service provider’s cloud. The ordered service provider has managed the hosting for the customer for a fee.

What is Cloud Computing?

Cloud computing is the delivery of resources and services through a network of shared hardware and software that reside on remote servers and are accessed through a network. This means you don’t own or manage any technology but instead access it via the Internet cloud. You can, for example, use a shared spreadsheet on someone’s computer over the Internet without knowing anything about the computer’s technical setup.

It is also referred to as “virtual computing.” A cloud provider like Amazon offers various storage, computing, and software services. The advantage of using a cloud provider is that it saves you time by letting you outsource tasks that used to take up a lot of your time, like managing the technical setup of employees’ computers, to a service provider.

Advantages of Cloud Computing

Cloud providers offer several advantages over managed services providers. First, you get access to a broader range of services and benefits, like automatic backup and disaster recovery. The second is that you don’t have the costs associated with data center maintenance or power. Another advantage of cloud computing is that you are not limited to using the technology of a single provider since the cloud is an open network where anyone can offer a service. This means you can access a broader range of technologies and services without being limited to the ones a managed service provider offers.

Managed Services vs. Cloud Computing

Managed services and cloud computing benefits organizations looking to improve their technology capabilities. With managed services, organizations can benefit from expert monitoring and management of their technology infrastructure and data management strategies that can help them extract valuable insights from the data they collect. With cloud computing, organizations can benefit from scalable, cost-effective solutions allowing them to access their data anywhere.

Managed services can help organizations leverage machine learning and business intelligence to make informed business decisions. At the same time, cloud computing can provide the flexibility and scalability needed to support growth and innovation. Both approaches can offer high data governance and security, which is critical for organizations that handle sensitive information.

Ultimately, the choice between managed services and cloud computing will depend on an organization’s specific needs and goals. For organizations that require more control over their technology infrastructure, managed services may be the better choice. For organizations looking for more flexibility and scalability, cloud-based solutions may be the way to go. Regardless of the approach, organizations should seek a provider that offers a high level of service, data integration, and data warehouses to ensure they can make the most of their technology investments.

Managed vs. Platform as a Service

Managed services generally have a more limited scope and a more focused purpose than cloud computing. They are often used to supplement existing IT service delivery rather than replace it. A managed service usually has a defined scope and duration. The range includes the service type and the effort required to deliver it. The time of the contract is generally shorter than the scope. A platform as a service (PaaS) is a service that gives you access to an Application Programming Interface (API) that you can use to store your data and run specific programs, like a payroll service.

Conclusion

As you can see, managed services and cloud computing both have a lot of potential benefits, but it’s essential to know the differences between them to make the right choice for your organization. Both are effective ways to alleviate some of the pressure from your IT team and get access to resources that are not owned or managed by you. Suppose your organization is experiencing challenges managing the increasing volume of data created, the growing need for agility, or both. In that case, it might be worth analyzing the costs of managed services versus cloud computing.

Why Do My Servers Keep Crashing?

An organization’s worst fear is to have a server failure where essential data may be lost forever leaving your organization unable to function properly.

According to research, server failure rates rise noticeably as they age. The failure rate for a server within its first year is 5%, compared to a four-year-old server’s yearly failure frequency of 11%. Understanding server failure rates is helpful as it enables a more effective risk management as well as long-term planning for server administration and maintenance expenses.

Dealing with a server crash is never enjoyable. Users may encounter significant disruptions if a large company’s server collapses, resulting in significant financial loss. If your host’s server crashes and you are an individual with a single website, you are at the mercy of the host leaving you to pace away until the problem is fixed.

A server crashing is bound to happen at some point time so it’s a good thing to note what exactly a server crash is and why it happens.

What is a Server Crash?

A server crash is a catastrophic failure of a server that can affect the entire operation of a business as well as cause a severe financial loss. Server crashes usually occur when a server goes offline, preventing it from performing its tasks. There can be issues with the server’s numerous built-in services once it crashes. Additionally, the impact will be more significant, and the repercussions will be more severe because the server serves many customers.

• Video Website: A significant accessibility issue within a video website makes it impossible to watch any online videos. It would be a catastrophe if the server’s data was lost and many writers’ original animations and movies could not be recovered.
• Financial system: A rock-solid server is necessary for a financial plan that processes millions of transactions every second. Since everyone’s capital exchanges were impacted, the loss is incalculable.
• Competitive games: There may be tens of millions of participants online for most popular and competitive games. There will undoubtedly be a lot of upset gamers if they were all disconnected from their beloved game.
  

Reasons for Server Crash

A server may go down for various reasons, including occasionally, a single fault or multiple problems co-occurring at other times.

The following are the most typical reasons for server crashes:

• Startup Failure: This is the most common reason for a server crash. When your server starts up, the code must run before it starts doing its job. If some of these steps fail, your server will not start properly.
• A Software Error: The most common reason for a server crash is an application error, such as an unexpected exception or an operation that cannot be completed because of execution limits on the system.
• A Hardware Failure (such as a power outage): If the cause of your crash is a power outage, there may be no way to recover without restoring your backup data. If this happens, you should contact your hosting service provider and ask them what steps they recommend to restore service.
• Errors in Configuration Files or Other System Files: Sometimes errors occur in configuration files or other system files that result in incomplete or incorrect actions being taken by your application when it starts up, which can lead to crashes.
• Security Vulnerabilities: Security vulnerabilities are typically caused by hackers, allowing them access into your server. If you have a secured server, you should not be worried about this problem as your server is well protected from hackers.
• Overheating: If the server cannot keep itself cool, it will be unable to function correctly. If a server has an overheating problem, the system will shut down and restart itself. This may be caused by a faulty fan or power supply unit (PSU).
• Virus Attacks: Viruses can cause server crashes in many ways. One way is that they can infect your server’s operating system or hardware and cause it to crash when it tries to process requests from the internet. Another way is that they make your computer run slowly and eventually crash, which causes fewer requests for content from your server and makes it more likely that its hard drive will run out of space and have to be replaced.
• Expired Domain: Domain names are like URLs (uniform resource locators) for websites, but they have expiration dates set by the Internet Corporation for Assigned Names and Numbers (ICANN). When the expiration date passes, the domain name becomes available again, so any website using that domain must be changed manually. This can cause issues when your site goes offline due to a server crash because you no longer have access to the proper domain name.
• Plug-in Error: This happens when a server gets stuck in some loop and cannot exit it because it gets stuck in an infinite loop. For example, if you have two routers connected with a switch between them, but only one router works appropriately while the other one doesn’t, then both will be affected by this issue. If you don’t want this to happen, make sure both routers have enough power or buy a new one.

Server Crashes: Numerous Causes, Numerous Solutions

No two servers are the same and they all tend to crash for a variety of reasons. While some of them we have slight control of, others are out of our hands. There are, nevertheless, precautions we may take to reduce the risk. Although they aren’t impenetrable precautions, they can mitigate end-user disruptions and downtime.

What Is Network Observability, And Why Is It Demanded In The Cloud And IoT Era?

Implementing dynamic network infrastructure design has become more critical than ever to securely connect with people, devices, applications, and data to support our evolving working environment. What can be the first thing we need to consider for this challenge? We cannot control or secure all kinds of connectivity if we don’t see what is happening in our network. By default, networks are distributed systems, and network visibility is vital in distributed systems. However, can network monitoring be good enough to better network visibility in the Cloud and IoT era? If not, what can be the solution?

Today’s enterprise digital infrastructure is comprised of hybrid cloud and on-premise solutions. Complex operational models manage these technologies, but their operational visibility continues to be a concern for most businesses. Read how large enterprises are securing their data?

The best way to gain network visibility is by leveraging network observability rather than network monitoring. This article explains what network observability is, why it’s necessary, and how it can help you manage your hybrid cloud and IoT infrastructure.

What Is Network Monitoring?

Monitoring is a passive data collection and surveillance practice used to measure the performance against pre-set standards. Monitoring equipment has been deployed over the years depending on more static, traditional network environments without frequent changes. However, these tools can be deployed throughout the corporate network.

It offers a centralized view of the operational health of the underlying network and infrastructure. Network monitoring might give alerts based on connectivity, downtime, or service degradation but does not give deeper cause or hypothetical exploration of unknowns provided by an observability platform.

What Is Network Observability?

According to Gartner, Observability is the evolution of monitoring into a process that offers insight into digital business applications, speeds innovation, and enhances customer experience. So we should use observability to extend current monitoring capabilities. Network observability is intended to have a deep knowledge of network health to provide an optimal end-user experience. When teams observe networks deeply, they understand ways to solve problems, correct them, and improve network performance to prevent future errors. Here are the main differences:

The Current Challenges With Network Monitoring

The rapid shift towards cloud technology and related trends, such as SD-WAN, has changed the concept of network monitoring. Still, the traditional network performance monitoring tools are not keeping up with advanced networking technologies. Here are some issues regarding conventional network performance monitoring tools.

• Traditional Network Performance Monitoring (NPM) tools do not include metadata or routing policy, network security, or cloud orchestration information.
• Basic network connectivity info such as IP/MAC and port numbers are insufficient to analyze network traffic securely.
• The tools can’t handle cloud scalability, as cloud customers produce terabytes of VPC flow logs every month. So Typical network packet sniffer solutions do not work in the cloud environment.

Conclusion

As mentioned above, challenges associated with network observability can be solved by implementing a combination of network monitoring and network analytics solutions. These solutions can help you get a high-level view of network activities across your hybrid cloud and on-premise environment. – Network monitoring: Network monitoring solutions are responsible for gathering network data from all network devices. They can help you identify issues that may affect business continuity and performance. – Network analytics: Network analytics solutions can be used to gain insights into network activities, such as network anomalies, performance, and capacity issues. Additionally, the data from the network monitoring solutions can be used to build network analytics dashboards.

Protected Harbor Zero Trust NAC can solve the challenge.

Network observability is necessary to ensure that the networks remain secure, reliable, and scalable. It is crucial for organizations that rely on hybrid cloud and IoT architecture. A hybrid cloud architecture, cloud migration, and end-to-end digital transformation are the primary reasons for network observation being demanded. A Zero Trust network architecture is the best way to achieve network observability.

Protected Harbor’s Hybrid Cloud Network Orchestration and Security platform is powered by a Zero Trust Network Access Control (NAC) engine. This network access control engine is designed to enforce a Zero Trust architecture and help achieve network observability by:

Device identity: Identify devices and enforce access rules based on device identity and user identity.

User identity: Identify users and enforce access rules based on user identity.

Endpoint compliance: Detect and enforce endpoint compliance using agentless endpoint compliance and vulnerability assessment.

Endpoint threat detection: Detect and quarantine endpoints with malicious activities in real-time.

Session visibility: Monitor and analyze all network traffic to detect suspicious activities during a session.

Session compliance: Detect and enforce session compliance based on policies.

Session threat detection: Detect and quarantine sessions with malicious activities.

Session compliance enforcement: Ensure all network traffic conforms to the policy.

Session visibility: Monitor and analyze all network traffic for all sessions.

Port visibility: Monitor and analyze all traffic on ports.

Protected Harbor Zero Trust Network Access Control (NAC) can log and monitor traffic coming from all branches and remote users using Cloud Gateway. The total network traffic can be observed. However, you can only watch and control unauthorized or non-compliant devices.

Most importantly, Protected Harbor Device Platform Intelligence powered by Cloud technology can enhance network visibility more contextually by correlating network connectivity info with business context (e.g., Connected devices’ EoL, EoS, manufacturer) and risk-related information like CVE. Overall, you can monitor and control all connected devices’ activities holistically without losing business performance, so you can substantially boost the success of an organization’s operations.

If you want to know more about how network observability can help your business, or if you want to see how you can simplify your network infrastructure, we’d love to talk.

What are the types of clouds? Which one’s best for your business?

When you think of cloud technology, the first thing that comes to mind is big companies like Google and Amazon using it to run their massive online operations. But the truth is, this type of software has many small-time entrepreneurs using it to run their businesses. And if you’re not sure which kind of cloud computing service is right for your business, here’s a brief explanation about the different types of clouds and why you should choose one over the other.

What is a Hybrid Cloud?

The hybrid cloud integrates private cloud services, public cloud services, and on-premises infrastructure. It provides management, orchestration, and application portability over all three cloud services. As a result, a unified, single, and flexible distributed computing environment is formed. An organization can deploy and scale its cloud-native or traditional workloads on the appropriate cloud model.

The hybrid cloud includes the public cloud services from multiple cloud service providers. It enables organizations to

• Choose the optimized cloud environment for each workload
• Combine the best cloud services and functionality from multiple cloud vendors.
• Move workloads between private and public cloud as circumstances change.

A hybrid cloud helps organizations achieve their business and technical objectives cost-efficiently and more effectively than the private or public cloud alone.

Hybrid Cloud Architecture

Hybrid cloud architecture focuses on transforming the mechanics of an organization’s on-premises data center into the private cloud infrastructure and then connecting it to the public cloud environments hosted by a public cloud provider. Uniform management of private and public cloud resources is preferable to managing cloud environments individually because it minimizes the risk of process redundancies.

The hybrid cloud architecture has the following characteristics.

1. Scalability and resilience

Use public cloud resources to scale up and down automatically, quickly, and inexpensively to increase traffic spikes without affecting private cloud workloads.

2. Security and regulatory compliance

Use private cloud resources for highly regulated workloads and sensitive data, and use economic public cloud resources for less-sensitive data and workloads.

3. Enhancing legacy application

Use public cloud resources to improve the user experience of existing applications and extend them to new devices.

4. The rapid adoption of advanced technology

You can switch to cutting-edge solutions and integrate them into existing apps without provisioning new on-premises infrastructure.

5. VMware migration

Shift existing on-premises infrastructure and workloads to virtual public cloud infrastructure to reduce on-premises data center footprint and scale according to requirements without additional cost.

6. Resource optimization and cost savings

Execute workloads with predictable capacity on the private cloud and move variable workloads to the public cloud.

Hybrid cloud advantages

The main advantages of a hybrid cloud include the following.

• Cost management_ Organizations operate the data center infrastructure with a private cloud. It requires a significant expense and fixed cost. However, a public cloud provides services and resources accounted for as operational and variable expenses.
• Flexibility_ An organization can build a hybrid cloud environment that works for its requirements using traditional systems and the latest cloud technology. A hybrid setup allows organizations to migrate their workloads to and from the traditional infrastructure to the vendor’s public cloud.
• Agility and scalability_ Hybrid cloud provides more resources than a public cloud provider. This makes it easier to create, deploy, manage, and scale resources to meet demand spikes. Organizations can burst the application to a public cloud when demand exceeds the capacity of a local data center to access extra power and scale.
• Interoperability and resilience_ A business can run workloads in public and private environments to increase resiliency. Components of one workload can run in both environments and interoperate.

What is a Public Cloud?

A public cloud is a computing service provided by third-party service providers across the public Internet. It is available to anyone who wants to use these services or purchase them. These services may be free or sold on-demand, allowing users to pay per usage for the storage, bandwidth, or CPU cycles they consume. Public clouds can save organizations from the cost of buying, maintaining, and managing on-premises infrastructure.

The public cloud can be deployed faster than on-premises and is an infinitely scalable platform. Each employee of an organization can use the same application from any branch through their device of choice using the Internet. Moreover, they run in multi-tenant environments where customers share a pool of resources provisioned automatically and allocated to individual users via a self-service interface. Each user’s data is isolated from others.

Public cloud architecture

A public cloud is a completely virtualized environment that relies on a high-bandwidth network to transmit data. Its multi-tenant architecture lets users run the workload on shared infrastructure. Cloud resources can be duplicated over multiple availability zones for protection against outages and redundancy.

Cloud service models categorize public cloud architecture. Here are the three most common service models.

• Infrastructure-as-a-Service_ in which third-party providers host infrastructure resources, such as storage and servers, and virtualization layer. They offer virtualized computing resources, such as virtual machines, over the Internet.
• Software-as-a-Service_ in which third-party service providers host applications and software and make them available to customers across the Internet.
• Platform-as-a-Service_ in which third-party service providers deliver software and hardware tools for application development, such as operating systems.

Advantages of Public Cloud

The public cloud has the following advantages

1. Scalability

Cloud resources can be expanded rapidly to meet traffic spikes and user demand. Public cloud users can gain high availability and greater redundancy in separated cloud locations. Apart from the availability and redundancy, public cloud customers get faster connectivity between the end-users and cloud services using the network interfaces. However, latency and bandwidth issues are still common.

2. Access to advanced technologies

Organizations using cloud service providers can get instant access to the latest technologies, ranging from automatic updates to AI and machine learning.

3. Analytics

Organizations should collect useful data metrics they store and the resources they use. Public cloud services perform analytics on high-volume data and accommodate several data types to give business insights.

4. Flexibility

The scalable and flexible nature of the public cloud allows customers to store high-volume data. Many organizations depend on the cloud for disaster recovery to back up applications and data during an outage or in an emergency. However, it’s tempting to store all data, but users must set up a data retention policy to delete data from storage to reduce the storage cost and maintain privacy.

Limitations or challenges of Public cloud

• Runway costs_ Increasingly complex pricing models and cloud costs make it difficult for companies to track IT spending. It is cheaper than on-premises infrastructure, but sometimes organizations pay more for the cloud.
• Limited controls_ Public cloud customers face the tradeoff of restricted control over the IT stack. Moreover, data separation problems arise due to multi-tenancy and latency issues for remote end-users.
• Scarce cloud expertise_ The skill gap among IT experts in the cloud is another challenge. Without expertise, companies can’t handle the complexities of advanced IT demands.

What is a Private Cloud?

A private cloud is defined as computing services provided over a private internal network or the Internet, only to specific users rather than the general public. It is also known as a corporate or internal cloud. The private cloud provides many benefits to businesses, such as scalability, self-service, and elasticity to a public cloud. In addition, it gives extended, virtualized computing resources through physical components stored at a vendor’s data center or on-premises.

One of the main advantages of the private cloud is that it provides an enhanced degree of control to organizations. As it is accessible to a single organization, it enables them to configure the environment and manage it in a unique way tailored to the particular computing needs of a company.

A private cloud can deliver two models for cloud services. Infrastructure-as-a-Service enables a company to use resources, such as network, storage, and computing resources. And platform as a service that allows a company to deliver everything from cloud-based applications to sophisticated enterprise applications.

Private Cloud Architecture

A private cloud with a single-tenant design is based on the same technologies as other clouds. Technologies that allow customers to configure computing resources and virtual servers on demand. These technologies include

1. Management software

It provides administrators with centralized control over the applications running on it, making it possible to optimize availability, resource utilization, and security in the private cloud environment.

2. Automation

It automates the tasks, such as server integrations and provisioning, which must be performed repeatedly and manually. Automation minimizes the need for human intervention and gives self-service resources.

3. Virtualization

It provides an abstraction to IT resources from their underlying infrastructure and then pooled into the unbounded resource pools of storage, computing, networking, and memory capacity divided across multiple virtual machines. Virtualization allows maximum hardware utilization by removing the physical hardware constraints and sharing it across various applications and users.

Moreover, private cloud customers can leverage cloud-native application practices and architecture, such as containers, DevOps, and microservices, to bring greater flexibility and efficiency.

Benefits of private cloud

Advantages of private cloud include

• Freedom to customize software and hardware_ Private cloud users can customize software as needed with add-ons via custom development. They can also customize servers in any way they want.
• Full control over software and hardware choices_ Private cloud users are free to buy the software and hardware they prefer or services provided by the cloud service providers.
• Fully enforced compliance_ Private cloud users are not forced to rely on the regulatory compliance provided by the service providers.
• Greater visibility and insights into access control and security because all workloads execute behind the user’s firewalls.

Challenges or Limitations of private cloud

Here are some considerations that IT stakeholders must review before using the private cloud.

• Capacity utilization_ Organizations are fully responsible for enhancing capacity utilization under the private cloud. An under-utilized deployment can cost significantly to a business.
• Up-front costs_ The cost of required hardware to run a private cloud can be high, and it will need an expert to set up, maintain and handle the environment.
• Scalability_It may take extra cost and time to scale up the resources if a business needs additional computing power from a private cloud.
