This article helps you understand the pros and cons of the possible high availability solutions and will help you decide which solution is right for you.
With an ever increasing dependence on IT infrastructure to perform critical business processes, the availability of this infrastructure is becoming more important. The failure of an IT infrastructure results in large financial losses. The solution to this problem is careful planning to ensure that the IT system is resilient to any hardware, software, local, or system wide failure. This capability is termed "resilience computing", which addresses the following topics:
- High availability
- Fault tolerance
- Disaster recovery
- Workload balancing and stress
This article addresses the most fundamental concept of resilience computing, high availability. It explains how you can easily configure and achieve high availability using IBM's enterprise messaging product, WebSphere® MQ V5.3 and later.
