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, with the Twitter tag #dljcjug

The Docklands.LJC will meet on the second Tuesday of each month. At this event we are delighted to have two excellent speakers coming to talk:

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.

The presentation and video recorded from the event are are available from InfoQ.

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:

  • Lust - embracing the latest and greatest technology without evaluating the
  • Gluttony - using excessive communication protocols
  • Greed - trying to have too many systems
  • Sloth - composing services in a lazy fashion, which ultimately leads to the creation of a “Distributed Monolith” operational impact incurred by these choices
  • Wrath - failing to deal with the inevitable bad things that occur within a distributed system
  • Envy - introducing inappropriate intimacy within services by creating a shared domain model
  • Pride - selfishly ignoring the new requirements for testing
