With the constant growth of enterprise networks, the demand of application servers is also increasing. Studies show that over the past few years, there is a huge change in the users’ behavior when it comes to choosing a server for a business. In the present scenario, thousands of people can easily access a single database application, at the same time. Sometimes, it becomes quite difficult to support the functions of a high performance hardware with a single cluster. This may often cause problem to the business owners, causing delay in the load time of the website. This can result into the dissatisfaction of the users, which business owners are not ready to accept at any cost. This is why the idea of combining multiple servers together are becoming so popular among business owners.
However, one may wonder what a server cluster is. Basically, it’s a group of multiple resources and servers which act as a single system. This enables improved service, high availability and sometimes, also parallel processing and load balancing.
Though the benefits of using a server cluster are quite obvious, not all businesses can benefit from it equally. This is because the requirements of different businesses are widely varied and whether or not your business would be able to benefit by using a server cluster depends on a number of factors. Here are some such factors that you must consider before investing in a server cluster –
- Check the hardware considerations – Before you plan a server cluster environment, you must check the hardware that you will need. There are certain environments that need special kind of servers that are originally designed in a way so that these can be clustered together. While buying servers for clustering you should keep in mind that any server that was designed for clustering, won’t work for the environment that you are planning. This is why it’s essential to check the compatibility of the hardware beforehand.
- Be aware of the software considerations – In order to make a server cluster run perfectly, it’s not enough to have the right operating system and hardware. You should also consider the software requirements. The application must be suitable for the cluster environment so that you can make use of it in the best way possible. Although it’s possible to make an application, which is originally not cluster aware, ideal for the environment, it’s not advisable to do the same, since there are many complications in this process.
- Judge the applications properly – It’s of utter importance to regulate the time that is dedicated by each of the machines to each tasks that they are performing. This helps track the importance of the different applications, individually. While planning the server cluster environment, you must be able to decide the actual processor time that each of the applications receives. It’s also important to know how to handle a server failure. Figure out if the remaining processing power is dedicated to the most critical application.
These are some of the major considerations that you must do before investing in a server cluster environment.Tags:
