Apache Tomcat sort ses griffes

Le Jeudi 15 Décembre l’AlpesJUG a le plaisir de recevoir Jean- Frederic Clere pour parler du futur d’Apache Tomcat (en français).

Apache Tomcat Next

This presentation will provide an update on the Tomcat 9 implementation of the next versions of the JavaEE specifications that most impact Tomcat (Servlet, JSP, EL and WebSocket).

There will be a particular focus on the progress of HTTP/2 support.

The Tomcat 8.5 which brings the HTTP/2, SNI etc in a java7 and EE7 is the step before EE8 will be presented. The configuration changes and migration to earlier Tomcat versions will be discussed and the roadmap to the next stable Tomcat releases will be presented.

Using OpenSSL to Boost JSSE in Tomca

In Tomcat-native and Tomcat9 it is now possible to use the NIO and NIO2 connectors with OpenSSL and have a a full support of HTTP/2 with TLS/SSL. JSSE is known to have poor performances compared with OpenSSL additionally ALPN required by HTTP/2 won’t be in the JVM before java9.

The goal of the new connector is to get ride of the old APR connector and use the NIO or NIO2 one and still have the performances of OpenSSL.

Additionally the tc-native can be used in other java web server for example undertow, the presentation will explain how and demo it quickly.

The presentation will explain the new code and the corresponding configuration and show the performance improvements: With the new piece of code Tomcat with the NIO or NIO2 connector gives even a better throughput than with the old APR connector!

Microservices scalables avec OpenShift le Mercredi 30/11/2016

Le Mercredi 30Novembre l’AlpesJUG a le plaisir de recevoir Clément Escoffier pour parler microservices dans le cloud (en français).

Microservices scalables avec OpenShift

Vert.x is a framework to create reactive distributed and polyglot applications on the Java Virtual Machine.

Vert.x takes the JVM to new levels of performance yet having a small API. It lets you build scalable microservice-based applications transparently distributed and packaged as a single jar file.

Due to this simplicity, deploying and managing Vert.x applications on OpenShift is a breeze, upload your jar and Vert.x internal cluster manager will connect all your pods in single distributed network. Several examples are shown during the talk and demonstrate how Vert.x can simplify DevOps daily job when working together with OpenShift such as deployment, rolling updates, monitoring, metrics…

Clément Escoffier (Red Hat) :
Who am I? That’s a good question. I had several professional lives, from academic positions to management. Currently, I’m working for Red Hat as Vert.x core developer. I have touched to many domains and technologies such as OSGi, mobile app development, continuous delivery, DevOps…

My main point of interest? Software engineering, so processes, methods, tools that make the development of software more efficient and also more fun. I’m also an active contributor to many open source projects such as Apache Felix, iPOJO, Wisdom Framework, and obviously, Eclipse Vert.x.
