UCSD initiated the Enterprise Systems Renewal (ESR) program, which would transform and streamline core business and administrative processes. It is the largest technology improvement program ever undertaken at UC San Diego. ESR addresses key goals identified in UC San Diego’s Strategic Plan, including creating an agile, sustainable, and supportive infrastructure. The integration Platform as a Service (IPaaS) was rolled out to support the ESR program. It is a next-generation integration platform that can support capabilities such as streaming, batch, APIs, events etc. This session describes the roll-out and optimization of the integration platform called iPaaS (integration platform as a service) for the execution of UCSD’s ESR Enterprise System Renewal.
