New and expanding workloads are increasingly demanding more from enterprise mainframe systems. These workloads include applications running in the cloud, analytics, mobile device access to business applications, social media, and improvements in security. All these workloads are bombarding the IT systems with requests for information and providing new data to existing business applications.
