Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. Without enough infrastructure (physical or virtualized servers, networking, etc.),

Physalia is designed to offer consistency and high-availability, even under network partitions. In fact, each key needs to be available at only three points in the network: the AWS EC2 instance that is the client of the volume, the primary copy, and the replica copy. In practice, however, achieving high availability is challenging.
