Service Availability

Availability Management is one of five components in the ITIL Service Delivery area. It is responsible for ensuring application systems are up and available for use according to the conditions of Service Level Agreements (SLA).  CDT’s Service Level Management (SLM) practice serves to enhance quality and customer expectations of IT Services through formalized Service Level Agreements. The following services have Service Level Agreements:

  • z Systems Service Availability Plan
  • CGEN Service Availability Plan
  • CalCloud Service Availability Plan

The purpose of this practice is to ensure that existing and future availability requirements for service offered by CDT can be provided cost-effectively and meet the vital business needs of its customers.  Availability is a foundational factor in the formation of Service Level Agreements (SLA) and upon which SLA warranties and penalties are calculated.
