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. If a primary server fails, a backup server can take over and continue to serve requests.

The focus of most published research in architecture is on applications implemented in high-performance, “ close-to-the-metal” languages essentially developed before computers got fast. Programmers continue to write applications in them, and they continue to evolve: the just approved C++20 standard is the latest example.

An example of a specification is the correct operation of the hardware of a microprocessor. For example, high energy particles tend to produce transient faults, whereas defects can cause intermittent or permanent faults. An example protection technique that can provide this capability is an Error Correcting Code (ECC).
