Evolution of Application Server Usage

- Ubiquitous Applications, Ambient Computing- Mainframes, Servers, Personal Computers, small, resource-

constrained electronic devices

- Examples:- mobile, home, public services- M2M, Home Automation and RFID-based applications…- health care (sensor and personal communication devices)- Telco and Internet mixed applications ->convergence between

IMS, Web and Media service technologies

- New Requirements- dynamic service-oriented platform which is able to personalise

itself- embedded system domain- inter domain interoperability- support flexibly adaptable distributed applications

Application Servers


OSGi based Application Server

- Bridge the gap between the different parts of new generation applications: servers, edge, premise, devices …

- OSGi provides new key features to application servers- Dynamicity, flexibility, modularity, pluggeability, reduced

footprint …

- The resulting platform benefits from AS features- Transaction, persistency, security …

- High Availability, scalability (clustering solutions)

- Advanced management (self-management)


Unbreakable Application Server

- non-stop self-healing application server for mission critical applications, suitable for ambient computing

- fully OSGi-based distributed and scalable architecture- Result from advanced research in component and services

models

- full service continuity thanks to- Automated reconfiguration and management- Smooth and transparent migration solutions- High availability clustering solutions

- Based on- Java EE-compliant JOnAS OSGi-based application server- JASMINe administration environment- EJB3-compliant EasyBeans lightweight container

4 key elements to deliver a non stop application server platform, suitable for ambient computing


Scalable platform

OSGi’s architecture and technology:

- Services grouped into « Bundles »

- Dynamic and on demand services

- Modularity (Java EE 6 Profiles)

- Pluggable: easier integration with existing software

- Dynamic re-configuration

- Automatic adaptation to runtime constraints

- Java EE access <=> OSGi

Rapid development

EJB3 container: EasyBeans

- Architecture: performance and resource optimization

- Lightweight and modular

- Pluggable: embeddable in JOnAS, Tomcat, Jetty

- Available as OSGi bundles

- Hot deployment. Smart factory (client container)

- Supplied with JPA implementations (Hibernate Entity Manager, Apache OpenJPA,

TopLink Essentials)

- EJB3: a new simple way to create Java EE applications

- EJB3 clustering

EasyBeans


EasyBeans: Java EE™ OSGi™ Interaction

- Java EE ™ modules communicate with the OSGi™world

- EJB ™ 3.0 can use the BundleContext

- Listen to OSGi™ events (framework, bundle, service)

- Access to OSGi™ services

/** Bundle context that will be injected by the EZB container.*/@OSGiResourceBundleContext bundleContext = null;

Easy clustering

Dynamic clustering and large scale support

- End to End solution

- Web / mod_jk&mod_proxy / replication

- EJB / cmi V2 / HA (Terracotta, pair replication)

- New version of the clustering protocol CMI, for EJB2

and EJB3, performance oriented

- Dynamic re-configuration of the load balancing logic

(via the console)

- Dynamic and transparent update of the API

- Simplified deployment

JASMINe

- JASMINe Design- Graphic tool for building a middleware

configuration

- JASMINe Deploy- Framework for deploying a middleware

configuration

- JASMINe Monitoring- Tools for performance tracking and error

detection

- JASMINe Self-management- Control loop for Self-optimization & Self-

healing

- JASMINE Repository- Static and dynamic data regarding

managed system

Advanced Management


JASMINe Design


JASMINe Monitoring

- Error Detection- Based on Drools rules engine- Rules Examples :

• Error logs or counter aggregation• Cpu overload detection over a significant period (ignore peak load)�• Memory saturation is close• Datasource bottleneck

- Actions : alarms, mail, … extensible.

- MBeanCmd- Java Command relying on JMX- Read/Write JMX attributes, JMX methods invocation- Shortcuts for probing the most relevant JOnAS indicators

• Tx,datasource, http connectors, threads pool, jms statistics…

- JASMINe EoS- Dynamic Flex Console for managing JASMINe Monitoring


JASMINe Monitoring

- Visualisation environment resulting from an advanced configuration of JASMINe EoS


Advanced Management: Versioning

- Context- 24/24 7/7 Critical Java EE Applications with quick evolution cycle

- Version Upgrade

• without service interruption

• Without loosing user sessions

• Without over sizing the system

- Principle

- Several versions of a same application co-running in a sameJOnAS instance

- Configurable request routing policy toward versions

- Available for WebApp Tomcat, EJB2/EJB3

JASMINe


Advanced management

� Improved Quality of Service

� Automatic Deployment

� Better reactivity

� Decreased Risks

� Self-behaviours: self repair, self optimisation…
