You may have several triggers to investigate the feasibility of moving a workload or set of workloads to the IBMAr System zAr platform. These triggers could be concerns about operational cost, manageability, or delivering the agreed service levels, among others. Investigating the feasibility of a possible migration or transition to any other platform, including System z, requires a number of basic steps. These steps usually start with an understanding of the current workload and its pain points, and end with a business case to move the workload. It is important to find out how easy a migration is going to be and how much risk will be involved. In this IBM RedbooksAr publication we offer thoughts on how to move through these steps. We also include a chapter with a System z technology summary to help you understand how a migrated workload may fit on the platform. Our focus in this book is on workloads that are mission-critical and require a high level of availability, including disaster recovery.Service level management involves implementing Service Level Objectives ( SLOs) to meet the needs of the business. ... resolution and tracking of problems that may originate in hardware, software (operating system and application code) , anbsp;...
