State of the Container

Jeremy Brown – [email protected] 2013

A Short History● 1995 – Jetty (originally IssueTracker/MBServler)

● 1997 – Java Servlet Spec

● 1998 – Weblogic and Websphere Java Application Servers

● 1999 – Tomcat Servlet Container

● 1999 – JEE Spec (then J2EE 1.2), JBoss AS (now called Wildfly)

● 2004 – Spring Framework 1.0

● 2009 – JEE 6 Released (EJB fixed)

● 2013 – JEE 7 (HTML5, Websockets etc.)

4

Meanwhile...● PHP - Zend

● Ruby on Rails

● Python – Django

● Scala – Akka/Play Framework

● Node.js – game changer - non-blocking I/O and a single-threaded event loop

● Vert.x – polyglot, JVM based, non-blocking I/O, aschronous programming model, distributed event bus

● In Memory Computing

● Platform as a Service - PaaS

5

Thoughts● The JEE Container has been commoditised!

● JEE is here to stay, continue to evolve and support “new stuff”

● Event Driven/In Memory Computing – I Need to consider new programming models – are they relevant or a better solution for my use case

● Polyglot/Multi-container is proliferating – Can I leverage this?

● What is my PaaS strategy?


In-Memory Computing

Cost of memory since 1957

Problem: How to fix the response time problem?

Design for more...

● Pile on complex code, servers, databases, DBAs

● Cost-prohibitive

● Quick fix until you need to scale again

Start from scratch...

● Completely re-architect

● Sharding? Denormalization?

● Complicated

● Time- and resource-intensive

● Risky

“By 2014, at least 40%of large organizationswill have deployed oneor more in-memorydata grids.”

Solution: Introduce a Data Grid

● Insert a Grid between the App and the overloaded DB

● Small application changes esp. With e.g.

● Memcached

● Hibernate OGM

● Orders of magnitude response time speed up

Let’s take a look…

OpenShift is a PaaS on top of… Infrastructure

AWS / CloudForms / OpenStack (IaaS) / RHEV (Virt) / Bare Metal

11

The Foundation of OpenShift is Red Hat Enterprise Linux

RHEL RHEL RHEL

OpenShift is Built on Instances of Red Hat Enterprise Linux (RHEL)

RHEL


12

An OpenShift Broker Manages Multiple OpenShift Nodes

Nodes are where User Applications live.

Brokers keep OpenShift running.

Why OpenShift?

• It’s Trusted. OpenShift is built on proven Red Hat technologies.

• It’s Freedom. In OpenShift, work the way you want.

• Choice of Interface: Web Console, Command-line, or IDE

• Choice of Middleware: Java(EE6), Ruby, Node.js, PHP, Python, and Perl

• Choice of Cloud: Public, Private, or Hybrid Cloud

• Automatically Scaling: Eliminates the worry of handling load

It’s Open. OpenShift’s open source software stack ensures application portability and No Lock-In.
