Planning the Service's High-Availability Implementation

Messaging-service availably can be affected in a large number of ways. Being aware of these factors and how to mitigate them is important when designing a plan for high availability. Adopting good patching and maintenance procedures will go a long way in keeping your messaging platform stable. (You can find more information on patching in Chapter 17 of this book.) No matter how many procedures you adopt, a flawed design can still cause undue frustration. It is important to be aware of any single point of failures in your environment. Care should be taken to choose hardware that best meets the availability requirements. Having redundant power supplies and hot-swappable disk drives in a RAID (redundant array of independent disks) set are important considerations. Also, improperly sized hardware can cause service outages when load exceeds the capacity of the server. Exceeding load can happen when the processors or memory aren't ...
