Availability is best described as the time a particular resource is accessible and usable. Customers in today's networked world require any time, any where access to essential services, meaning the underlying systems, data and applications need to be continuously available. But high availability (HA) isn't just about delivering 99.999% - the fabled five nines - uptime for your IT infrastructure. It's about identifying the business criticality of individual IT systems, tackling all the causes of downtime - people and processes as well as products - and minimizing the total cost of availability.

High Availability Lifecycle
IT professionals who make purchase decisions and manage an infrastructure often get caught in a tug-of-war between the demand to improve service levels and the pressure to reduce service level costs. This means that IT professionals juggle two very difficult roles. The first is answering to the internal organization, namely the CIO and CFO. In this role, IT professionals are tasked with reducing or maintaining the cost of managing, sustaining, and evolving the infrastructure.

Simultaneously, they are burdened with guaranteeing that end users have access to business systems at any moment. Here, they must satisfy business managers' quality-of-service expectations for the company's customers. Striking a balance on this internal/external seesaw is tricky indeed. Those IT professionals who don't stay on budget or lack confidence in the system's ability to provide total business availability suffer through many sleepless nights. Embarking on a seven-step approach to availability positions you for success on both fronts.

  • Step 1: Inventory systems by business impact - Classify each system based on how downtime would affect the company's bottom line.
  • Step 2: Analyze availability in tiers - Plan for different levels of availability based on the criticality of the application or system.
  • Step 3: Mitigate availability cost and risk architecturally - Design a system that meets service level targets at a cost proportional to the business criticality of the system.
  • Step 4: Reduce the time to value - Know when your availability solution will start paying off.
  • Step 5: Address the complete environment--products, processes, people - Reduce the overall cost of business availability by factoring in all the components that comprise an infrastructure.
  • Step 6: Design and implement comprehensive recovery plans - Establish a swift response to failure for each system to lower business risk and keep revenue streams intact.
  • Step 7: Partner for experience - Get predictable business availability from Jaggy
