The 6 Rules for Modernizing Your Legacy Java Monolith with Microservices

Kevin Webber illustrates the Microservices approach

View on Slideshare

We change a monolithic system only when we have no other choice. Traditional enterprise systems are tightly-coupled; all-in-one, all-or-nothing, difficult to scale, difficult to understand and difficult to maintain.

Rather than swiftly capture opportunity, we ponder if it’s really worth it—is it worth upsetting the delicate balance of the house of cards we call our enterprise system? Often the opportunity quickly disappears, captured by a faster company. Some people have started calling this “Getting Ubered”.

So what can you do about it? Talking about Microservices is one thing, but how can your organization start taking action to address this issue?

In this webinar by battle-hardened Enterprise Advocate, Kevin Webber, we walk through the 6 key concepts to understand as a guide for taking action:

  • Domain Driven Design (DDD)
  • Asynchronous messaging 
  • API management
  • Dependency management
  • CQRS & event sourcing
  • Transactions & ordering
