Steve Elliott – Java at 20 and Where we are Going

Daniel Bryant – The Seven Deadly Sins of Microservices

We are pleased to bring you the second event of the Docklands.LJC (; a group within the main London Java Community that will be focusing on the developer community in and around Docklands on the 2nd Tuesday of each month. #dljcjug (

Steve Elliott – Java at 20 and Where we are Going

This talk will look back at where Java has come from over the last two decades and where it is going in the future. It will provide a high level overview of the Java release cycle, the different versions and updates and look at the future challenges and how Java will evolve going forwards, including some of the things that may be in Java 9 such as Jigsaw, the sun.* changes, the G1 garbage collector, VarHandles and future projects such as Valhalla and Panama.

Daniel Bryant – The Seven Deadly Sins of Microservices

All is not completely rosy in microservice-land. It is often a sign of an architectural approach’s maturity that in addition to the emergence of well-established principles and practices, that anti-patterns also begin to be identified and classified. In this talk we introduce seven deadly sins that if left unchecked could easily ruin your next microservices project...

This talk will take a tour of some of the nastiest anti-patterns in microservices, giving you the tools to not only avoid but also slay these demons before they tie up your project in their own special brand of hell. Topics covered include: Pride - selfishly ignoring the new requirements for testing; Envy - introducing inappropriate intimacy within services by creating a shared domain model; Wrath - failing to deal with the inevitable bad things that occur within a distributed system; Sloth - composing services in a lazy fashion, which ultimately leads to the creation of a “Distributed Monolith”; and Lust - embracing the latest and greatest technology without evaluating the operational impact incurred by these choices.

Who should attend:

Anyone who is interested in Java or JVM based technologies, whether in the Docklands or further afield, is welcome to attend.
