n the world of DevOps and the cloud, most developers have to learn new technologies and methodologies. The focus tends to be on adding capabilities such as resilience and scaling to an application. One critical aspect consistently overlooked is security. In this session, learn about a few of the simple actions you can take (and some behaviors you must change) to create a more secure Java application for the cloud.

Everyone is talking about building “cloud native” Java applications—and taking advantage of microservice architecture, containers, and orchestration/PaaS platforms—but there is surprisingly little discussion of migrating existing legacy (moneymaking) applications. This session aims to address this, and, using lessons learned from several real-world examples, it covers topics such when to rewrite applications (if at all), modeling/extracting business domains, applying the “application strangler”… Show more

Everyone is talking about building “cloud native” Java applications—and taking advantage of microservice architecture, containers, and orchestration/PaaS platforms—but there is surprisingly little discussion of migrating existing legacy (moneymaking) applications. This session aims to address this, and, using lessons learned from several real-world examples, it covers topics such when to rewrite applications (if at all), modeling/extracting business domains, applying the “application strangler” pattern, common misconceptions with “12-factor” application design, and the benefits/drawbacks of container technology.

Two years ago at Devoxx UK we talked about DevOps, what it was, why it was important and how to get started. Boy, was it scary. Now we’re wiser. More battle-scarred. The large scale of the challenge for application writers exploiting cloud and DevOps is clearer, but so is the path forward. Understanding the DevOps approach is important, but equally you must understand specific deployment technologies, security issues, operational reliability, and how to drive organisational transformation… Show more

Two years ago at Devoxx UK we talked about DevOps, what it was, why it was important and how to get started. Boy, was it scary. Now we’re wiser. More battle-scarred. The large scale of the challenge for application writers exploiting cloud and DevOps is clearer, but so is the path forward. Understanding the DevOps approach is important, but equally you must understand specific deployment technologies, security issues, operational reliability, and how to drive organisational transformation. Whether creating simple applications or sophisticated microservice architectures many of the challenges are the same. Join us to learn how you can apply this within your team and company. Show less

Worried about the future of Java? Want to see it keep moving forward? Don't be concerned. The transformation of Java is already underway. Driven by new technologies and new opportunities Java and the JVM are entering uncharted worlds and challenging old approaches. In this session learn about one such expedition in the form of an introductory talk to technology being developed by IBM. This experimental technology is exploring a new way to share data between the JVM and other runtimes. This new approach radically reduces the cost of data sharing and introduces new capabilities to Java that will benefit everyone, not just those interested in high speed interoperability. In a nutshell PackedObjects is designed to allow better control over the layout and form of fields within an Object. This approach provides better, faster, easier inter-op with native code. Would you like to be able to really share data with native applications? No copying, no special, arcane APIs. Just Java classes on one side, C style structures on the other and a lot less JNI. Even if you don't directly work with JNI the platform level benefits are potentially enormous. Faster interoperability with any native code means faster networking performance, faster I/O and faster graphics rendering. Ever tried to write a 3D game in Java and been bottlenecked by OpenGL interoperability? PackedObjects can help eliminate the performance pain point. Come to this session and see PackedObjects in action. Show less

This session discusses the technical, business, and personal challenges involved in creating a new type of “social” Website where developers from all walks of life can work together on their common passion: helping keep Java great. Building and testing code is something all developers understand. The presentation uses that common understanding of the challenges involved to help demonstrate the design and implementation of a unique system built for Java by Java developers.

Whilst Java is a feature rich, there are still areas where it looks enviously at other languages. Native languages like C boast the ability to specify arrays of structures which has the benefit of being able to have compact representation of data and allow for the fast conversion of data into a stream of bytes (ie. serialization). It's possible to achieve the same things in Java by carrying out direct memory management yourself through the use of the Unsafe class, but as the name suggests this… Show more

It's possible to achieve the same things in Java by carrying out direct memory management yourself through the use of the Unsafe class, but as the name suggests this can be perilous. This session will introduce the concept of bringing C like structures to Java through a proposed Java Language change, and show the improvements possible for the memory footprint and performance of applications.
