The limitations of the single server triggered the need for server clustering. And clustering proved effective in offering a better experience to organizations. It ensured high availability of applications, minimized downtimes, and made recoveries faster. Server clustering offered business continuity like no other. In spite of all its benefits, cluster servers are not commonplace.
Are there any problems with server clustering that prevent organizations from deploying it? Yes, clustering has certain limitations.
Not all types of servers can be clustered. In fact, not all applications are supported by server clustering. Thus, it loses its purpose if your applications cannot be supported.
You are required to acquire and maintain many servers. Your infrastructure will increase, and so will your maintenance overheads.
Some cluster designs are extremely expensive and complicated. It is not easy to implement and maintain all types of cluster designs. And they can be just beyond the budget.
The security of data is not guaranteed. It is your responsibility to take measures to ensure data security.
If you are not limited by a budget, server clustering will work for you. However, it is important to make sure that all your applications are supported by the cluster design you are going for. You should also be willing to and capable of taking care of the cluster and the security of data.
The benefits of clustering will entice you. Make sure you have looked into its limitations before you commit to it.
