High Availability Communication

High availability Communication is the elimination of single points of failure to enable applications to continue to operate even if one of the IT components it depends on, such as a server, fails. To ensure continuous operation and uptime at least 99.99% annually.

High availability is an essential for Server infrastructures and it indicates IT systems able to ensure performance and SLA next to 100 percent over time.

It is achieved by creating clusters, a group of servers that act as a single server to provide continuous uptime. Having access to the same shared storage for data, so if a server is unavailable, the other servers pick up the load.
