High-availability on Application Layer (also known as HA clusters or fail-over clusters) is a group of servers that support applications that can be reliably utilized with a minimum amount of down-time. This layer operate with the load balancer to harness redundant application servers in clusters that provide continued service even though some of the apllication servers fail, as long as one application server is up.
We can assist you to setup your EPrints or DSPace application on HA capability, means you will have your application on more than 1 server, incase one of the application servers is down, the other application server/s could still continue to provide the service to your client. The HA Application Layer can be more than 2 servers and the Load Balancer need to work together with the HA.
