Managing consistency, state, and identity in distributed microservices

Duncan DeVore (Lightbend)
4:50pm–5:40pm Tuesday, February 27, 2018
Secondary topics:  Best Practice, Theoretical

Who is this presentation for?

  • Architects, CIS managers, and programers

Prerequisite knowledge

  • Familiarity with Java and the JVM

What you'll learn

  • Learn best practices for distributed computing, including state management, behavior management, and identity realization (aggregation) in a distributed environment

Description

Building distributed Java applications is markedly different from traditional monolithic design. In this new modular landscape, we face many challenges: parallelism, asynchronous boundaries, state management, identity management, and consistency deficiencies, to name a few. Of all these problems, consistency, state management, and identity management can be particularly challenging. Duncan DeVore discusses the ins and outs of dealing with modular JVM-based application consistency, distributed state, and identity coherence with techniques such as idempotency, eventual and casual consistency, the CAP theorem, single source of truth, and distributed domain design.
