Throughput vs. Uptime: The Two Sides of Real Performance

Throughput vs. Uptime:

The Two Sides of Real Performance

 

 

Throughput and uptime are two crucial elements working together to affect business performance.

 

Uptime is a basic metric that essentially means — is your system alive? Throughput is the rate at which a system, network, or process produces, transfers, or processes data within a defined timeframe.

 

A real-world way to think of throughput is as miles per gallon. It measures how much useful output (miles traveled) is produced per unit of input (one gallon of fuel). Or in an environment — what is actually going on in the deployment? How efficiently is the system performing? How much data can be moved within a certain amount of time?

Uptime then is a question of — does the car turn on?

 

Uptime is a crucial metric to look at, but it doesn’t tell the full story. This is where other metrics like throughput come in.

My Uptime Is Fine — Why Does Throughput Matter?

 

Uptime is important, but uptime alone doesn’t tell you the full performance story.

 

Downtime is obvious. It’s very clear to any organization when their system isn’t online, which means downtime is usually easy to spot across organizations. Throughput issues, their effects, and how they’re noticed highly depend on the organization impacted.

 

For example, a radiology organization works with large numbers of complex scans. A company like this might not notice drops in throughput because so much data is being processed so often, their workload isn’t sensitive in that way.

 

However, what about an organization that provides medical transportation to patients for doctor’s appointments, hospital visits, etc.? For this type of organization, a drop in throughput would be felt right away. Their queue of callers would build and their ability to address them would be compromised.

 

A relatively small drop in throughput can have a proportionally oversized business impact depending on how an organization operates. Even though uptime isn’t this nuanced, it simply isn’t enough to say that you provide 99.99% uptime. Uptime is a just measurement of if your application is online or not.

It guarantees access, but it doesn’t guarantee performance or responsiveness.

 

Uptime and throughput are especially important to consider during the hours your business operates, as this is when your environment sees the heaviest traffic. Downtime during business hours will immediately halt all productivity and impact every customer. Even though throughput might not have such a dramatic effect, times of heavy traffic are when we most often see issues bottlenecking throughput. Work may still be getting done, but it’s slowed down to such a degree that it can significantly hurt your business.

 

You want to ensure you have a system that can stay online and perform well no matter the time of day or traffic load.

 

How Do Uptime & Throughput Impact Organizations?

 

There’s a difference between your system being on and your system actually keeping up with your business.

 

Let’s say you’re experiencing a network issue:

Customers and staff can be online — the system is ‘up.

However, the network is unable to process requests, and requests that can be processed have volume limitations because of infrastructure degradation — poor throughput.

 

Whether you’re experiencing downtime, issues with throughput, or both, the trickle-down effects of these problems can seriously impact your organization.

 

The system is online, but barely functional OR your application is frequently ‘down’.

  • Work is delayed or not getting done at all.
  • Employees and customers are left frustrated.
  • Staff get fed up and leave.
  • Customers feel they can’t trust your organization to deliver what you’re offering.
  • Profits take a hit.
  • Your reputation is on the line.

 

For example, in the field of radiology, uptime and throughput can impact business in the following ways:

 

Doctors can’t do their jobs — they can’t get patient results or see patients in a timely manner.

Patients have trouble checking in — it takes a long time for anyone to provide help or clear answers because office staff can’t access the PHI they need.

Staff decide to leave your practice, further hurting productivity and efficiency.

Patients get fed up and chose to switch to a different organization.

Revenue decreases and trust in your organization is hurt.

 

Minimal connections or connections constantly going ‘down’ can also cause problems with images and patient data being written to disk, creating further issues for the integrity and performance of the practice.

 

Providing reliable, unmatched performance gives you a competitive edge.

 

When you have a deployment designed for your organizational needs and built for scale, you have an environment that consistently performs the way it should — eradicating disruptions from downtime or poor throughput.

 

Customers trust that you’ll be able to deliver on your promises.

Staff aren’t left frustrated by lags, crashes, etc.

Reputation and profits are bolstered, not threatened

 

Uptime and throughput are two sides of the same business growth coin. If you can’t scale good uptime and throughput, no matter what kind of organization you have, you risk the death of your business.

Why Uptime Alone Doesn’t Tell the Full Story

 

 

Uptime is an important metric, but it’s also been the most cited metric for a very long time. In the days of old, outages and inconsistent service were just part of the game. Uptime was adopted as a critical metric in the early 2000s because having a product that was online most of the time set companies apart. Today, hardware and software are more advanced than they used to be. Now, if a company cannot provide 99.99% uptime, they’re not considered a serious contender in the field.

 

This doesn’t mean uptime isn’t as important as it used to be, it just means that it’s not the only crucial metric you should be paying attention to. Having a system that is slow is better than a system that won’t come online, but having a fast system is better than both of those options. For example, if a page loads in 30 seconds versus 1 second, both are considered ‘up’, but one is nearly unusable.

 

At Protected Harbor, we treat uptime as the baseline — not the definition — of performance.

 

Performance Depends on Throughput & Design

 

Computers are logical — they only do what they’re designed to do. This means that it’s crucial that a deployment is designed correctly/ tailored to the unique needs and goals of your business. How your environment was built plays a crucial role in both uptime and throughput.

 

Was your environment built with your unique business workflow in mind?

Was your environment built for scale?

What happens when systems aren’t designed to handle sustained, simultaneous work?

 

Throughput measures how much of a thing can be done in a specific time period. Throughput is critical, especially at scale, because if you can’t add more users, features, reports, etc., then the platform slowly deteriorates.

 

If your organization hasn’t made a fundamental code change in a couple of decades, this will make any mobility now extremely painful and time consuming.

 

Maybe your organization is trying to make do with a hodge podge of servers trying to balance requests or put specific clients in specific places. This is unsuccessful because it’s arduous to manage, not sustainable, and doesn’t address core infrastructure deficiencies.

 

When your business is still starting out, a bad deployment won’t have the same impact as trying to scale to 1,000 users or even 100. Business growth exposes the architectural limits of a deployment not built for scale. This creates a painful user experience, threatening productivity and customer satisfaction. A scalable environment is crucial because without it, the growth of your organization is severely limited. If your business can’t grow, you die.

 

Another issue is misinterpreting problems as they arise. Let’s use an analogy: renting a speed boat as a novice versus an experienced fisherman.

 

As a novice, you can steer around a lake, catch some fish, catch some sun, but you’re not a skilled fisherman. You don’t know where the different schools of fish are, what the currents are like, how the water moves, or even how you should maneuver your boat to be most optimal. Now something that seemed trivial at first is actually more complicated. It involves understanding the weather, the lake, and your boat all at the same time to be efficient.

 

This analogy helps us understand why some IT teams misinterpret the data. They are the novice renting a boat, but they have the same contract as a fisherman, which is an impossible task.

 

A skilled professional has the knowledge and tools necessary to build an environment for heavy workloads and scaling your unique organization. They also know how to properly define metrics of performance for your specific workflow. This helps them understand when things are working well and when there are issues. They can then quickly and efficiently respond to those issues to ensure performance isn’t impacted.

 

At Protected Harbor, owning the full stack allows performance metrics to become actionable instead of confusing. We design environments around real workflows, define the right performance signals, and respond before slowdowns turn into business problems.

 

This same philosophy extends to Service Level Agreements (SLAs). An SLA is an agreement that a certain level of service will be provided by your Managed Service Provider (MSP). While uptime belongs in any agreement, it shouldn’t be the only metric. Responsiveness, latency, capacity under load, and consistency matter because they reflect how work actually gets done — not just whether systems are online.

When an issue is spotted, our system will flag it and notify our technicians immediately. This allows our engineers to act fast, preventing bottlenecks and downtime instead of responding after they’ve already happened.

 

Framework: How Do Throughput & Uptime Impact You?

 

Throughput and uptime are crucial metrics to pay attention to. They work together to either support or damage business performance. Organizations need environments built around their specific demands and built for scale. They also need a Managed Service Provider who has the expertise and tools required to support a successful environment.

 

A poorly designed deployment will only get worse as your business tries to grow.  Preventing downtime and throughput issues helps to increase efficiency, bolster productivity, and ensure staff and customers are satisfied — which all combines to equal a positive reputation, supported business growth, and increased profits.

 

Consider:

  • Are you experiencing frequent downtime? — If not, is your throughput adequate?
  • What metrics are included in your Service Level Agreement (SLA)? — Do those metrics actually reflect the workflow of your business?
  • Are you satisfied with the agreed upon level of service being provided?
  • Is your Managed Service Provider effectively meeting the requirements of your SLA? — Are they doing the bare minimum or going above and beyond?

Benefits of Managed ServicesThe-Role-of-Managed-Services-in-Reducing-Downtime-Middle-image

1. Cost Savings

Outsourcing IT management to a managed services provider can result in significant cost savings. Businesses can avoid the expenses associated with hiring and training in-house IT staff, purchasing and maintaining hardware, and dealing with unexpected repair costs. Managed services offer predictable monthly fees, making budgeting easier.

2. Improved Efficiency

With managed services, businesses can streamline their IT operations and improve overall efficiency. By offloading routine tasks to an MSP, internal teams can focus on strategic initiatives that drive growth and innovation. This improved efficiency translates into better productivity and a stronger competitive edge.

3. Increased Uptime

The primary goal of managed services is to maximize uptime. With proactive monitoring, regular maintenance, and swift issue resolution, MSPs ensure that systems remain operational and available. This increased uptime directly impacts business continuity, customer satisfaction, and revenue generation.

4. Access to Advanced Technology

Managed services provide businesses with access to the latest technology and industry best practices.

This access to technology ensures that businesses stay ahead of the curve.

5. Focus on Core Business Activities

By outsourcing IT management, businesses can focus on their core activities and strategic goals. Managed services free up valuable time and resources, enabling companies to concentrate on what they do best. This focus on core competencies enhances overall business performance and growth.

 

Network Update Management

Without regular updates, network softwares can become a hotspot for security vulnerabilities, leaving organizations susceptible to data breaches. The consequences of such breaches extend far beyond downtime prevention, potentially leading to the loss of intellectual property and sensitive customer information.

Implementing a robust network update management strategy doesn’t have to be costly or time-intensive. In fact, studies by CSO reveal that basic scanning and patching could have prevented 60% of data breaches. For larger organizations, the challenge grows with scale, but proactive IT support simplifies the process. Leveraging centralized network monitoring tools, managed service providers (MSPs) automate updates and install patches during off-hours, minimizing disruptions.

However, updating must be done with precision. Improperly applied updates can lead to misconfigurations, causing performance issues and operational headaches. Experienced MSPs understand the nuances of network softwares and can recommend which updates are essential for security and performance while avoiding unnecessary changes.

By combining proactive IT support, network monitoring tools, and strategic update management, businesses can achieve reliable downtime prevention while safeguarding their IT infrastructure against potential threats.

 

Proactive Monitoring and Prevention

For organizations looking to enhance their IT capabilities, partnering with IT managed services providers can offer a game-changing solution. Top providers prioritize proactive maintenance to maximize productivity and minimize downtime. By leveraging automation, artificial intelligence (AI), and expert oversight, managed services for IT focus on identifying and addressing issues before they impact business operations.

Many businesses still operate reactively: an issue arises, a ticket is created, and IT teams work to resolve it. While effective, this model often results in costly downtime. In contrast, a proactive approach emphasizes preventing problems entirely. IT teams utilizing proactive maintenance monitor systems continuously, perform regular performance reviews, and address minor issues before they escalate into major disruptions.

Advanced tools like AI and automation are critical to this approach. These technologies detect subtle irregularities, predict potential failures, and even implement self-healing solutions without human intervention. This allows technicians to focus on tasks that require expertise while automation ensures continuous system performance.

The benefits of managed services for IT extend beyond reduced downtime. Organizations gain greater efficiency, cost savings, and peace of mind knowing their IT infrastructure is well-maintained. Adopting a proactive model ensures smoother operations and long-term business success.

Why Do My Servers Keep Crashing?

Why Do My Servers Keep Crashing banner

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 crashing causes and fixes 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 crash is bound to happen at some point in time, so it’s a good thing to note what exactly a server crash is, why it happens, and how to troubleshoot server crashes.

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.
    Why Do My Servers Keep Crashing middle

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 common reasons servers crash:

  • 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 server crashing causes and fixes, and precautions we may take to reduce the risk. Although they aren’t impenetrable precautions, they can mitigate end-user disruptions and downtime.

Outages and Downtime; Is it a big deal?

Outages and DowntimeOutages and Downtime; Is it a big deal?

Downtime and outages are costly affairs for any company. According to research and industry survey by Gartner, as much as $300000 per hour the industry loses on an average. It is a high priority for a business owner to safeguard your online presence from unexpected outages. Imagine how your clients feel when they visit your website only to find an “Error: website down” or “Server error” message. Or half your office is unable to log in and work.

You may think that some downtime once in a while wouldn’t do much harm to your business. But let me tell you, it’s a big deal.

Downtime and outages are hostile to your business

Whether you’re a large company or a small business, IT outages can cost you exorbitantly. With time, more businesses are becoming dependent on technology and cloud infrastructure. Also, the customer’s expectations are increasing, which means if your system is down and they can’t reach you, they will move elsewhere. Since every customer is valuable, you don’t want to lose them due to an outage. Outages and downtime affect your business in many underlying ways.

Hampers Brand Image

While all the ways outages impact your business, this is the worst and affects you in the long run. It completely demolishes a business structure that took a while to build. For example, suppose a customer regularly experiences outages that make using the services and products. In that case, they will switch to another company and share their negative experiences with others on social platforms. Poor word of mouth may push away potential customers, and your business’s reputation takes a hit.

Loss of productivity and business opportunities

If your servers crash or IT infrastructure is down, productivity and profits follow. Employees and other parties are left stranded without the resources to complete their work. Network outages can bring down the overall productivity, which we call a domino effect. This disrupts the supply chain, which multiplies the impact of downtime. For example, a recent outage of AWS (Amazon Web Services) affected millions of people, their supply chain, and delivery of products and services across all of their platforms and third-party companies sharing the same platform.

For the companies who depend on online sales, server outage and downtime is a nightmare. Any loss of networking means customers won’t have access to your products or services online. It will lead to fewer customers and lesser revenues. It is a best-case scenario if the outage is resolved quickly, but imagine if the downtime persists for hours or days and affects a significant number of online customers. A broken sales funnel discourages customers from doing business with you again. There the effects of outages can be disastrous.

So how do you prevent system outages?

Downtime and outages are directly related to the server and IT infrastructure capabilities. It can be simplified into Anticipation, Monitoring, and Response. To cover these aspects, we created a full-proof strategy that is AOA (Application Outage Avoidance), or in simpler words, we also call it Always on Availability. In AOA, we set up several things to prevent and tackle outages.

  • First of which is to anticipate and be proactive. We prepare in advance for possible scenarios and keep them in check.
  • The second thing is in-depth monitoring of the servers. We don’t just check if a server is up or down- we look at RAM, CPU, disk performance, application performance metrics such as page life expectancy inside of SQL. Then we tie the antivirus directly into our monitoring system. If Windows Defender detects an infected file, it triggers an alert in our monitoring system so we can respond within 5 minutes and quarantine/cleans the infected file.
  • The final big piece of this is geo-blocking and blacklisting. Our edge firewalls block entire countries and block bad IPs by reading and updating public IP blacklists every 4 hours to keep up with the latest known attacks. We use a windows failover cluster which eliminates a single point of failure. For example, the client will remain online if a host goes down.
  • Other features include- Ransomware, Viruses and Phishing attack protection, complete IT support, and a private cloud backup which has led to us achieving a 99.99% uptime for our clients.

These features are implemented into Protected Harbor’s systems and solutions to enable an optimum level of control and advanced safety and security. IT outages can be frustrating, but actively listen to clients to build a structure to support your business and workflow – achieving a perfect mix of IT infrastructure and business operations.

Visit Protected Harbor to end outages and downtime once and for all.

What Functions Best? Virtualization vs. bare metal servers

What Performs Best

 

What Performs Best? Bare Metal Server vs Virtualization

 

Virtualization technology has become a ubiquitous, end-to-end technology for data centers, edge computing installations, networks, storage and even endpoint desktop systems. However, admins and decision-makers should remember that each virtualization technique differs from the others. Bare-metal virtualization is clearly the preeminent technology for many IT goals, but host machine hypervisor technology works better for certain virtualization tasks.

By installing a hypervisor to abstract software from the underlying physical hardware, IT admins can increase the use of computing resources while supporting greater workload flexibility and resilience. Take a fresh look at the two classic virtualization approaches and examine the current state of both technologies

 

What is bare-metal virtualization?

Bare-metal virtualization installs a Type 1 hypervisor — a software layer that handles virtualization tasks — directly onto the hardware before the system installing any other OSes, drivers, or applications. Common hypervisors include VMware ESXi and Microsoft Hyper-V. Admins often refer to bare-metal hypervisors as the OSes of virtualization, though hypervisors aren’t Operating Systems in the traditional sense.

Once admins install a bare-metal hypervisor, that hypervisor can discover and virtualize the system’s available CPU, memory and other resources. The hypervisor creates a virtual image of the system’s resources, which it can then provision to create independent VMs. VMs are essentially individual groups of resources that run OSes and applications. The hypervisor manages the connection and translation between physical and virtual resources, so VMs and the software that they run only use virtualized resources.

Since virtualized resources and physical resources are inherently bound to each other, virtual resources are finite. This means the number of VMs a bare-metal hypervisor can create is contingent upon available resources. For example, if a server has 24 CPU cores and the hypervisor translates those physical CPU cores into 24 vCPUs, you can create any mix of VMs that use up to that total amount of vCPUs — e.g., 24 VMs with one vCPU each, 12 VMs with two vCPUs each and so on. Though a system could potentially share additional resources to create more VMs — a process known as oversubscription — this practice can lead to undesirable consequences.

Once the hypervisor creates a VM, it can configure the VM by installing an OS such as Windows Server 2019 and an application such as a database. Consequently, the critical characteristic of a bare-metal hypervisor and its VMs is that every VM remains completely isolated and independent of every other VM. This means that no VM within a system shares resources with or even has awareness of any other VM on that system.

Because a VM runs within a system’s memory, admins can save a fully configured and functional VM to a disk or physical servers, where they can then back up and reload the VM onto the same or other servers in the future, or duplicate it to invoke multiple instances of the same VM on other servers in a system.

 

 

Advantages and disadvantages of bare-metal virtualization

Virtualization is a mature and reliable technology; VMs provide powerful isolation and mobility. With bare-metal virtualization, every VM is logically isolated from every other VM, even when those VMs coexist on the same hardware. A single VM can neither directly share data with or disrupt the operation of other VMs nor access the memory content or traffic of other VMs. In addition, a fault or failure in one VM does not disrupt the operation of other VMs. In fact, the only real way for one VM to interact with another VM is to exchange traffic through the network as if each VM is its own separate server.

Bare-metal virtualization also supports live VM migration, which enables VMs to move from one virtualized system to another without halting VM operations. Live migration enables admins to easily balance server workloads or offload VMs from a server that requires maintenance, upgrades or replacements. Live migration also increases efficiency compared to manually reinstalling applications and copying data sets.

However, the hypervisor itself poses a potential single point of failure (SPOF) for a virtualized system. But virtualization technology is so mature and stable that modern hypervisors, such as VMware ESXi 7, notoriously lack such flaws and attack vectors. If a VM fails, the cause probably lies in that VM’s OS or application, rather than in the hypervisor

 

What is hosted virtualization?

Hosted virtualization offers many of the same characteristics and behaviors as bare-metal virtualization. The difference comes from how the system installs the hypervisor. In a hosted environment, the system installs the host OS prior to installing a suitable hypervisor — such as VMware Workstation, KVM or Oracle Virtual Box — atop that OS.

Once the system installs a hosted hypervisor, the hypervisor operates much like a bare-metal hypervisor. It discovers and virtualizes resources and then provisions those virtualized resources to create VMs. The hosted hypervisor and the host OS manage the connection between physical and virtual resources so that VMs — and the software that runs within them — only use those virtualized resources.

However, with hosted virtualization, the system can’t virtualize resources for the host OS or any applications installed on it, because those resources are already in use. This means that a hosted hypervisor can only create as many VMs as there are available resources, minus the physical resources the host OS requires.

The VMs the hypervisor creates can each receive guest operating systems and applications. In addition, every VM created under a hosted hypervisor is isolated from every other VM. Similar to bare-metal virtualization, VMs in a hosted system run in memory and the system can save or load them as disk files to protect, restore or duplicate the VM as desired.

Hosted hypervisors are most commonly used in endpoint systems, such as laptop and desktop PCs, to run two or more desktop environments, each with potentially different OSes. This can benefit business activities such as software development.

In spite of this, organizations use hosted virtualization less often because the presence of a host OS offers no benefits in terms of virtualization or VM performance. The host OS imposes an unnecessary layer of translation between the VMs and the underlying hardware. Inserting a common OS also poses a SPOF for the entire computer, meaning a fault in the host OS affects the hosted hypervisor and all of its VMs.

Although hosted hypervisors have fallen by the wayside for many enterprise tasks, the technology has found new life in container-based virtualization. Containers are a form of virtualization that relies on a container engine, such as Docker, LXC or Apache Mesos, as a hosted hypervisor. The container engine creates and manages virtual instances — the containers — that share the services of a common host OS such as Linux.

The crucial difference between hosted VMs and containers is that the system isolates VMs from each other, while containers directly use the same underlying OS kernel. This enables containers to consume fewer system resources compared to VMs. Additionally, containers can start up much faster and exist in far greater numbers than VMs, enabling for greater dynamic scalability for workloads that rely on micro service-type software architectures, as well as important enterprise services such as network load balancers.
