    .   Physical Server clustering in the event if there is a dedicated environment for the physical server.
    In the event if there is a physical damage like a hard ware failure, then we ensure that until the problem is fixed the work load is transferred to another physical server which is clustered.

    .   Virtual Server Clustering
    Under this technique, we go ahead and cluster the server which is nothing but a virtual image on a multiple hosting machine. We interlink the Virtual Machines(VM’s) with other machines which are compatible in the case of there is a software or hardware issue with the main Virtual Machine. This way, the Secondary Virtual Machines takes over to ensure smooth functioning.

    .   The Application High Availability
    In this method, we go ahead and focus on the approach for the application clustering instead of the complete Virtual Machine. This helps to balance the load and is tailored as per the type of Operating system that is being used by the client presently. Some of the most common operating systems are Solaris, Linux, Windows, Aix etc. There is also a physical and virtual setup. This method is generally used in order to ensure that there is not threat or downtime for the company in any form.
