DevCon – Java Frontier

Even after ten years, the Java Programming Language and Environment continue to stake out new territory. This talk will discuss some of the directions that the language, and things being built using the language, are going.

We will start by talking about some of the things that were presented at JavaOne in San Francisco. Rather than discussing the big-bang announcement items, we will try to concentrate on the small but innovative uses in the Java ecosystem that may show where the mainstream will be in the next five years.

We will then move on to talk about some of the work being done in Sun Microsystems Laboratories. In particular, we will talk about attempts to move the Java environment to the extremes. On one side, we will look at moving Java to ever smaller devices (in this case, wireless sensors). At the other, we will look at the work that is trying to build large-scale, very long-lived systems exploiting Java.

Building and Deploying 12 Factor Apps in Scala and Java

April 18, 2017

The twelve-factor app is a modern methodology for building software-as-a-service apps:

• Use declarative formats for setup automation, to minimise time and cost for new developers joining the project.

• Have a clean contract with the underlying operating system, offering maximum portability between execution environments.

• Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration.

• Minimise divergence between development and production, enabling continuous deployment for maximum agility.

• And can scale up without significant changes to tooling, architecture, or development practices.

We will build a RESTful web service in Java and deploy the app to CloudFoundry. We will go over how to build a cloud manifest, how to keep our database credentials and application configuration outside of our code by using user-provided services and go over what it takes to build a 12 Factor application in the cloud. This presentation will be heavy on code and light on slides!
