Application modernization is essential for all organizations, regardless of industry. To offer clients next-generation experiences and compete with new entrants in that industry, organizations must modernize their core applications and take advantage of modern architectural patterns such as microservices and event-driven architectures.

Modernizing old and fragile applications can be very challenging, time-consuming, and risky. Big Bang approaches don’t provide business value quickly enough, require a significant investment, and are a non-starter. Incremental approaches are technically complex and require substantial engineering; you need to establish a modern target architecture and a co-existence architecture. You need to simplify and standardize the integration. You need to figure out how you modernize the data.

In my role at IBM, I’ve worked with many clients that face the same challenges. This session will describe an event-driven Book of Reference pattern we call the “Digital Core” that we have leveraged to address these challenges. The pattern unlocks data in core systems of record breaking down data silos. It handles both streaming and batch data, leverages an industry-aligned data model, and has a speed layer based on Apache Ignite, among other capabilities. The pattern enables incremental modernization or complete replacement of a core system of record. It abstracts away the systems of record and the challenges that go with them.
