Any web application is expected to meet customer expectation by contributing to high performance. They are likely to have multiple requests at a single instance which is difficult to handle. Cluster architecture helps a system to overcome this issue. It is a system of interconnected nodes which works together in executing an application. In this scenario, a user will be ignorant about the multiple nodes and will have an impression that only a single system responds to the request. Through this article let us discuss cluster architecture along with its importance in database and web applications.

Cluster architecture has the requests or parts of the user requests divided amongst two or more nodes in such a way that a single user request is handled and delivered by two or more nodes. If one node fails, the user request is taken care of by another node. Hence the chances of complete system failure are less. A Cluster includes multiple tier and structures that depends on the need of the system.

Cluster architecture has the following benefits for any database and web applications.

Load balancing

When the process gets distributed across, vertical or horizontal scalability takes place. By this, the application can leverage resources more efficiently. Java GC is an example of this. If the user sessions get distributed to multiple JVMs, then GC would run less, and the performance would enhance. It will also overcome the JVM heap size limit.


Fail-over is less and shorter service disruption. Some SLAs may require high availability percentages like the two-line availability. A server may be down due to many reasons like a planned outage system failures network or network problems etc. For high availability of web applications and database, clustering is essential. Fail-over occurs either automatically, or manually. A backup system has to be in place which can serve the fail-over function.

As we all know that a computer is a machine that can have some hardware failures. To deal with such issues, the role of failover or high availability clusters comes into existence. These clusters maintain the service availability by replicating servers, and hardware and software configuration. Every system monitors one another and takes up the request if any one node fails. These types of clusters are useful for users who have a high-dependency on their computer systems.

The system should be efficient to know the current running systems, those that are assigned a request and the course of action when any failure occurs. Hardware like RAID systems or redundant boards provides fault-tolerance ability and connected networks which used when any path breaks.


The aim behind a high-performance cluster is to distribute high performing computer systems. They run many parallel programs that are mandatory for any time-exhaustive computations. It increases the performance by sharing the workload. They are mostly applicable in scientific and research industry, graphics rendering services and many more.


Having a cluster-architecture is motivated by the two primary objectives of scalability and high availability.
