Computer clustering offers a much more powerful system with a great deal of benefit to its users. The reduced costs of a powerful network of computers that are able to keep up with changing technologies appeal to many businesses which need a reliable system. There are different types of computer clusters, with each offering specific benefits. It is important to understand the differences in order to get a system that works best for what is needed by the end user. Among them are:
Load Balancing Clusters
These types of clusters work by taking information into one or more load balancing computers, which are called nodes, in the front, and dividing the workload evenly by spreading it out between the remaining nodes in the cluster. By distributing this work equally, it harnesses the limited processing power into a more powerful system. The load balancing cluster is designed to always be working, however if one node fails, the cluster will not work.
High Performance Clusters
High performance clusters are specifically designed to combine the processing power of parallel computers. These clusters are most common for applications that require one computer to be able to communicate with another in the cluster while performing its tasks. Often the results of one computer task will directly affect the future results of another in the cluster.
High Availability Clusters
When access is needed at all times to server applications, high availability clusters are used. They are designed to maintain nodes for backup systems in the case of a failure. The minimum amount of computers, or nodes, in one of these clusters is two. One is the active node, while the other is redundant and used in case of a backup. However, most high availability clusters have much more than just the minimum amount of computers. These HA clusters ensure continuous access to computer power, which is especially important for a business that relies on data processing that is time sensitive.
Cluster computing offers a lot of benefit to users who need to maximize power and efficiency, without extra costs.
