- #10: Systems of Engagement depend on services offered by mainframe applications. In many cases, those services in turn depend on older “legacy” applications. Organizations are gradually, incrementally, modernizing these applications by breaking them down into modular services. As they do, they modify the old applications to use the services as well; the services don’t just “wrap” the old application, they take over part of it. Services may have their own data, or they may come to own some of the corporate data. These service also are used to intermediate the interactions between legacy applications which helps to reduce complex inter-application dependencies.
