As technology has advanced, so too have our needs for fast processing power. With the explosion of smartphones, tablets, and computer use across every sector of society, there is an ever-growing need to perform these tasks as quickly as possible. Just look at how popular some games are!

With all this demand for lightning speed processing, we now have a term for it: parallelization. Parallelizing or dividing up work can be done in two ways: using clustering technologies or traditional architecture approaches.

Clustering is when separate computers are connected together to function similarly to create one efficient machine. This typically requires additional software (like Linux or Windows operating systems) and connectivity tools (such as WiFi or Ethernet cables).

Traditional architecture uses many different types of processors or hardware components to achieve similar results. These include things such as having multiple CPUs, GPUs, or ASICs (application specific integrated circuits).

This article will talk about why you should care about which type of cluster technology you choose and what benefits each offers. Then, we’ll dive into some examples of both types of clusters before making your choice.

What are the different types of clusters?

Clusters can be categorized into two main cluster architectures, depending on how you use them. If your cluster is only used for computing tasks that require heavy processing or large amounts of memory, then a traditional computer server-based cluster makes sense. These are typically referred to as clustered servers or centralized clusters.

A second type of cluster uses a distributed model. In this case, instead of having one very powerful node that does all of the work, several nodes contribute small chunks of work towards completing an overall task. This way, even if one node fails, the rest continue working until the job is done!

This article will talk about why distributing workloads across multiple computers is a better option than using a single, extremely fast machine with lots of RAM. It also goes over some examples of each cluster architecture in action. You will learn what it takes to run both Linux and Windows machines within a cluster, and how to manage all of the software needed to connect to the internet.

What are the differences between cloud and on-premise clusters?

As mentioned before, one of the biggest differentiators is where the cluster lives. A traditional enterprise data center cluster is built with dedicated hardware that connects to other servers using fast internal network connections like Gigabit Ethernet or higher.

These types of networks typically have very low latency, which means your computer software has a quick way to find resources such as databases or web applications. With these types of networks, it’s easy for all connected computers to talk to each other quickly, which helps promote faster overall system performance.

This is why most large companies use them — because they work well!

But what if there was a way to create speedier, more scalable server clusters than what people have been using traditionally?

A new approach

The technology behind the massively successful services we use every day -- from Facebook to Google to Amazon –is known as “cloud computing.” It allows you to pay only for what you need while still getting the full power of internet-connected computers. This article will go into more detail about how this is done.

Before we get too far, let us rewind and discuss something important: not all clouds are the same.

Not all clouds provide the same level of performance or reliability, nor do they all offer the same features. Make sure to check out our comprehensive comparison chart to see which ones fit best for your needs.

What are the different sizes of clusters?

A cluster size comparison is important to understand the differences between traditional architectures and clustered ones. The most common types of clustering you will come across include small, medium, large, and very-large scale clusters.

A small business or department may have an internal server that functions as their own private web domain. This internal server does not connect to the internet, so it does not meet the requirements for what we refer to as a classic infrastructure system.

A classic infrastructure system requires at least one public facing IP address and a DNS name attached to it. Systems like this are used in companies that want to create a unique online presence that can be accessed by anyone worldwide.

Publicly accessible servers are often referred to as being “on line” because they are no longer in use for creating individual domains but instead work together to provide users with seamless access to content and applications. Some examples of companies using this type of architecture are Amazon, Google, and Facebook!

The difference between these three giants is simply how many people use their service. With only tens of millions of users, they each had their own separate computer running their software and equipment was limited to just those few machines.

It is difficult to compare big company infrastructure to individuals and households since there are too many variables.

Who should run a cluster?

As we discussed, there are two main types of clusters- traditional architectures and cluster architecture. Both have their place depending on what you want to do!

With traditional clustering, one node does all of the work while other nodes exist solely to pass messages back and forth with the first node. For example, in an internal chat system, one user’s message would go from person to person until it is delivered.

This type of setup is great for many things such as having multiple people collaborate on an idea or sharing resources between several users.

Traditional clustering is appropriate when every job has a set process that repeats itself, and each worker has consistent hardware. This way, even if someone isn’t working, another can take over without any interruption.

Cluster architecture, however, is better when not everything is constant. For instance, say you wanted to create an online gaming platform where different games could be hosted on separate servers.

By using a cluster architecture, you can have one server that hosts a specific game and other servers that connect to this first server to retrieve extra CPU power or RAM.

This way, even though there is no direct connection, your server will still be able to function properly because they are connected through other servers.

What are the different cluster management systems?

A clustering software or hardware system is referred to as a clustered computing environment when it features parallelization of workloads across multiple computers. This allows for faster processing times because more copies of the data can be completed at once in comparison with having to process the same amount of work sequentially on one computer.

Most modern-day high performance computing (HPC) clusters use some form of clustered Linux or Unix operating systems, typically using either an embedded variant of Red Hat’s Fedora or Ubuntu distribution or another open source OS such as SuSE Enterprise Server, CentOS, or SLES. These types of OS’s have built-in support for virtual machine technology which makes them very easy to implement into HPC environments.

Another common type of clustered OS used in HPC is something called Nested Virtual Machine Clustering (NVMC). NVMC was originally designed and marketed by Sun Microsystems but has since been adapted and improved upon by many other vendors and developers. An example of this would be Google’s Chubby project that they developed back in 2008.

Cluster architecture concepts like these play a large role in how efficient your HPC job will run. If you are ever struggling to get your job to complete or if it takes far longer than expected to complete, make sure to check out whether or not your current settings are adequate. You may need to upgrade or downgrade certain components to see results.

What are the different cloud-based cluster architectures?

As we have seen, there is an ever-growing list of clustering software that people use to create clusters. Some of these products seem almost interchangeable at first, but in fact, they do quite different things!

What all of these clustering tools have in common is that they offer ways to connect computers or groups of computers into what’s called a “cluster.”

The term “cloud cluster” gets thrown around a lot these days, but most definitely it includes only two types of setups: shared cluster infrastructure (also known as public clouds) and private clusters. Let us take a closer look at each one.

Shared Clusters

A shared cluster is just like having your own personal computer except that many other users can access the resources on this computer too. This is not typically the case with individual PCs, because if someone else uses the same computer program you do, then their data will be lost when you close out of the app.

With a shared cluster, this is never a problem since everything is stored on a remote server instead of on your computer or the others’. Shared clusters are also usually much more cost effective than buying separate equipment or using off-the-shelf hardware that has limited capabilities.

Private Clusters

A private cluster is similar to a shared cluster, but instead of sharing the computer’s resources with everyone, only people who pay extra for access get access.

What are the different traditional cluster architectures?

Session clustering is one of the most fundamental types of clusters that can be built into an application. This article already discussed why session clustering is important, but it may still seem difficult to implement.

That’s okay! There are several ways to do this. One way is to use something like Redis or Node-Redis as your session store, and then have another service run in parallel using something like Apache Mesos or Kubernetes to manage the nodes for you.

Another option is to build your own custom solution by creating separate servers for each component of your app (web server, API server, UI server, etc) and linking them together with software such as NGINX or Vue Cli. Each of these solutions has their pros and cons, so pick whichever one feels more comfortable to you and learn from there!

General tips: remember to only add memory to your instances if they are idle! Overusing memory will cause your apps to slow down due to high overhead costs.

What are the pros and cons of each architecture?

While there is no right or wrong way to develop applications, some architectures have become very popular over time. One such architecture is called traditional architecture.

Traditional architecture was once the go-to choice for developing software. Back in the day, it was much easier to find experienced developers that used this approach. Since then, though, many experts believe that this approach has become outdated.

Why? Because modern technology allows us to create increasingly large-scale apps with less code. More importantly, we can use these tools to build almost as efficiently.

That’s why many development teams now prefer an alternative approach: cluster architecture.

In this article, you'll learn all about the benefits of clustering technology and how you can implement it into your own project.
