Business uptime is of utmost importance for any organization and critical data/application should be made available on timely manner. Clusters at various levels are the answer to have at first level of redundancy on hardware, application or OS based failure. We understand the criticality of outages and integrate/implement solution of clustering at various levels.
We design high available solution using clustering services of VMware, Microsoft Hyper-V and Database cluster from all the principle/s. Firewall redundancy at core level and distribution switching is another aspect we consider and implement to have no Single point of failure (SPOF).
