This statistic (80% of the World's corporate data resides or originates on Mainframes) caught my attention at IBM InterConnect. As IT has evolved, specifically in the most recent transition in conversation from Cloud to that of Hybrid-Cloud, we witness the traditional roots in everything we do. Mainframe or Systems of Record based on an Open Systems architecture is an essential part of any Hybrid Cloud implementation. Rarely does one find a Hyperscale only implementation, instead multiple components used to deliver on a single outcome. Mobile and web based applications are best hosted via a Managed or Unmanaged Public Cloud whereas customer database and financial records, used to support this application would reside on prem or in a private infrastructure next-to or near the Public Cloud.
