The server cluster consists of a unified set of servers that are hosted on a single IP address and managed as a group. As a result, the system is more reliable, has a better load balance, and is scalable.
In this setup, every server is a node with its own storage (hard disk), memory (RAM), and processing power (CPU).
A two-node cluster configuration, for example, means the second physical server automatically takes over if the first crashes. You can avoid downtime by using this process, called failover clustering.
Types of Server Clusters
Server clusters are divided into two categories – manual and automatic. There are advantages to manual clustering, but there are also disadvantages. Manual configuration of a node to the same IP and address leads to downtime. Having your system unavailable for even a few minutes can be expensive.
Server clusters: Why Are They Used? Or What Is the Purpose of Server Clusters?
To avoid downtime and ensure system accessibility, businesses often deploy a server cluster. Businesses experiencing performance degradation can also benefit from cluster architecture. With this solution, they can experience fast and uninterrupted performance for high-volume workloads by separating the database server.
As a result, a server cluster may be a good option for your business if it needs reliable IT services. In order to grow and perform in the long run, they are an essential investment. When clustering is implemented, performance will be improved, scalability will be enhanced, and reliability will be assured.
