Over-provisioning does not enable the infrastructure to cope with the constantly changing pattern, mix and volume of requests over time. Enterprises frequently find themselves with excess capacity in their infrastructure that they can t get to because they are isolated and dedicated for a single application. Delivering service quality linked to business objectives in a web-based application environment is an inherently difficult task, and while there are a number of tools that can measure the service quality, no methodologies and solutions are available to enable operations to proactively deliver consistently exceptional response times, in a dynamic environment. Monitoring and reporting tools have traditionally been used to manage the infrastructure. With this approach, hundreds of infrastructure metrics are monitored, and alarms are set off when metrics reach defined thresholds.
Operators react to the alarms and take actions to address the problem.
While this approach has been valuable for maintaining the health of the infrastructure, it is operationally expensive, inefficient and reactive in addressing service quality problems. There are simply too many metrics for human beings to define thresholds meaningfully correlated to service quality and a flood of events to manually handle to correct problems. The result is that operational costs have become the major portion of the cost of service delivery. Infrastructure architects and planners are struggling to build and operate cost-effective systems that deliver service quality today, can accommodate growth objectives, and mitigates the operational risk, uncertainty, and lack of precision.
