IBM integrated Web application server for i

the ‘on-ramp’ to the Web



Introduction – IBM Integrated Web Application Server for i

IBM integrated Web application server for i– Goals

IBM i functional enhancement

The Web container is integrated into IBM i OS

Easy to use

Simplified access, deployment and management

Small, Less resources

Positioned as ‘on-ramp’ to the Web

Replacement for AFS Tomcat



Introduction

Integrated Web application server

– What is it?

Web container

Based on the OSGI framework

Supports application packaged in a WAR

Runs IBM Technology for Java (32 –bit)

Supports Java Toolbox and Native DB drivers

Web container for ‘simple’ applications

64-bit



Why is this important to the IBM i?

It runs on our smallest boxes

Simple to use

Easy to install – part of the operating system (already included!)

Easy to maintain - PTFs

Starts very quickly (seconds)

IBM admin interfaces have a place run

– No Tomcat

– No WAS system instance

Replacement for Tomcat

Allow us to do things like

– Web Services Server

– Web Query

– IBM Navigator for i

– Application Runtime Expert for i

– Generates new excitement for IBM i

IBM Integrated Web Application Server for i (IAS)

Since IBM i 5.3 we have been leveraging a Web Container that has been

integrated into the OS (LWI) – Used by:

– Navigator

– Web Services

– Web Admin GUI

– LDAP

– DB2 Web Query

– Even Customer Applications (5.4 and beyond)

Now we support the Liberty server

– All above applications have been moved over

Liberty vs Tomcat

Tomcat Liberty

Size <20M <50M

Startup speed 1~3s <5s

Java EE JSP 2.2, Servlet 3.0, JSTL 1.2, need to add

jar for other standard support

JSP 2.2, Servlet 3.0, JSF 2.0, JSTL 1.2, JPA 2.0,

JDBC 4.0, JAX-RS 1.0, JNDI 1.0, Bean

Validation 1.0, SSL 1.0, Security 1.0, Web

Security 1.0, JMX 1.0

Can add or remove feature dynamically

OSGi support No Yes, support Blueprint 1.0, WAB 1.0

Dev tool Eclipse Eclipse, Rational Developer

Performance Normal Core is same to WebSphere Application Server,

good performance

App hot deployment Yes Yes

Configuration Multiple configuration files. Need to restart

after configuration update

Single configuration. Configuration update is

loaded immediately. No need restart

Migration Can move to WebSphere Application Server

by IBM Application Migration Toolkit

Programming model is same to WebSphere

Application Server. Can run on WebSphere

Application Server directly

Documentation Less document from official web site but

many documents from internet

http://wasdev.net, lots of documents, video,

examples. Can communicate with developer

directly

http://wasdev.net/



Liberty IAS Instance

•Only some limited physical files.

No any symbolic link. Less

possibility to hit by problem due

to messed file structure.

•All server configuration is in

only in one configuration file

server.xml.

•Very simple and easy to move

to another system.

Simple



Benefits of Moving IAS to Liberty

Fully supported, maintained, and enhanced Web Container

Ensure PCI Compliance

– Security Vulnerabilities corrected and patched

Server will be easier for compliance

– It is recognized, It’s a standard WAS server

Opens up new technologies we can leverage

– Web Services runtime engine for example

– Move to new JVM levels (improved performance)

Full Development tools support for user applications



Dynamic Server ProfileNot static like Web Profile –configured by app at a fine-grained level

Developer First FocusSimplified, shareable server config (like a dev. artifact). One XML file or several to simplify sharing & reuse of config. Adds MAC OS for development

Start fast, run efficiently

Starts in <3s

Memory footprint: <50MB

(TradeLite benchmark)

Lightweight cluster managementLiberty servers can join a lightweight cluster for workload balancing and high availability

Fidelity to full profile WASSame reliable containers & QOS. Develop on Liberty profile and deploy to Liberty or full-profile WAS

Dynamically ExtensibleInstall new features from a repository (local or remote) without server restart

New featuresCDI, JMS, JAX-WS, local EJB, OAuth, federated user repository, MongoDB, clustering, WebCache
