IT as a Service is one of the hottest topics these days. In a nutshell, it entails the radical alignment of all IT disciplines around strategic business requirements. Instead of having to beg IT for resources and services, as many of us are accustomed to, we can now pick all the resources and services from an easy-to-use online catalog. Workload automation features are finally becoming part of this service catalog, allowing business users to trigger, monitor, and even repair essential job flows.
Almost all of today's business processes are supported and complemented by enterprise IT applications. These applications are often business-critical and therefore tied to strict Service Level Agreements (SLAs). Most enterprises utilize sophisticated monitoring tools to track system health on the application, operating system, hypervisor, hardware, network resources, and storage levels. These health monitoring tools send out alerts to the administrator if any of the warning lights turn yellow or red. When all lights are green, there should be no problem.
