Appendix B High Availability Technology
As services grow, key applications must be available 24/7 and systems must have the fault tolerance capability. However, the systems with fault tolerance capability are costly. To lower the system costs, economical applications that provide the fault tolerance capacity are required.
A high availability (HA) solution ensures the availability of applications and data in an event of any system component fault. This solution aims at eliminating single points of failure and minimizing the impact of expected or unexpected system downtimes.
