A cluster is two or more interconnected computers that create a solution to provide higher availability, higher scalability or both.Clustering can be implemented at different levels of the system, including hardware, operating systems, middleware, systems management and applications.

that sounds very much like virtual servers, where you connect the servers together to give an illusion that there is only one large server taking all the load.

If your application needs to run without any failure, then you need a cluster solution. For an example, if you are running trading application, your application shouldn't go down, if it goes down, you will loose $x million dollars.
High availability ismore and more important in critical systems such as networked storage. Demands on these systems include not only ensuring
the availability of important data, but also efficient resource
sharing of the relatively expensive components.

Basically, if one of the systems goes down, other system will take over it and will run the application.

In a computer system, a cluster is a group of servers and other resources that act like a single system and enable high availability and, in some cases, load balancing and parallel processing.

Clustering is a popular strategy for realize similar processing applications because it enables companies to leverage the investment already made in PCs and workstations. The advantage of clustering computers for high availability is seen if one of these computers fails, another computer in the cluster can then assume the workload of the failed computer.

If this is about a cloud cluster, then a cloud cluster consists of multiple servers that support the functioning of the website irrespective of the website traffic. A clustered setup is beneficial to a high traffic website because even if one server fails, another server is available to balance the load and ensure the smooth functioning of the website.This is a great option for the online store websites as for them, downtime is something that might have a direct effect on the business.

Clustering, in the context of databases, refers to the ability of several servers or instances to connect to a single database. An instance is the collection of memory and processes that interacts with a database, which is the set of physical files that actually store data.
