Introduction to High Availability
High availability allows application processing to continue when a server instance fails and provides a reliable environment with minimal or no loss of service. High Availability is often achieved through the use of clusters, units of servers running concurrently to provide application failover and load balancing. Enterprise application deployments can benefit from the additional reliance and flexibility high availability systems provide.
Reasons for Implementing High Availability
Mission critical computer systems need to be available 24 hours a day, 7 days a week, and 365 days a year. However, part or all of the system may be inoperable during planned or unplanned downtime. A system's availability is measured by the amount of time that it provides service over the total time elapsed since the system's initial deployment.
System downtime may be categorized as planned or unplanned. Planned downtime refers to scheduled operations that render the system unavailable. The effect of planned downtime on end users is typically minimized by scheduling downtime when system traffic is slow. Unplanned downtime is any sort of unexpected failure. Unplanned downtime may have a greater effect than planned downtime because it can happen at peak hours, disrupt business operations, or lead to lost productivity or revenue.
When designing your P6 EPPM implementation, it is important to recognize the cost of downtime to understand how your services can benefit from availability improvements.
