Now let’s have a closer look at each feature. * The availability engine is the heart of everRun Enterprise. It ensures you won’t have business interruptions because your applications co-exist on two servers. If one server fails, the application continues to run on the other with no data loss, and no application restarts. The availability engine simplifies the process of making your applications available fault tolerantly by automatically creating the connections between two servers . * One application lives on two virtual machines. If one machine fails, the application continues to run on the other machine with no interruptions or data loss. If a component fails, it’s replaced with the healthy component from the 2nd system. The I/O is automatically mirrored to the redundant server. Memory check-pointing ensures all in-flight transactions as well as data in memory and cache is preserved - wit
