High availability is becoming increasingly important as our business depend more and more on computers. Unfortunately, many off-the-shelf solutions for high availability (HA) are expensive and require expertise. This paper explains the design and implementation of an inexpensive high-availability solution for our business-critical needs without requiring the use of expensive additional hardware or software. Along with discussion on high availability, this paper also discusses the data integrity of files and database, of the services which are to be made highly available. Using HTTP as the service example and MySQL as the database to be replicated for data integrity, a two node cluster has been configured to implement the concept.
