Today’s Environment Today… Many System z shops run their core, data-sensitive business processes on System z but also maintain distributed servers to accommodate a variety of processing that interacts with mainframe resources. System z Data Management Structure Core Business Applications Consolidation Security Low TCO § The mainframe has hosted most of the world’s business data and executed a majority of core business transactions § The mainframe is best suited for applications that require the highest levels of: – Reliability – Security – Performance – Availability – Service – Scalability § However, the mainframe is not optimized for all workloads 7 Distributed Systems Cycles Many ISV Applications Large Skill Pools Low TCA § There are particular industry application where distributed topology is the standard. § Distributed environments are suited for applications where: – High levels resource sharing is not required – The workload is • CPU intensive • Does not require high levels of data sharing • Highest levels of availability are not required § Other Distributed System Characteristics – Multiple management interfaces – Redundancy required for availability – On-site assembly – End-user service for problem resolution Aktuelles zu IBM z.
