The Tier Based Architecture

Cache A Typical Tier Scenario

The Tier Based Architecture Tier integration impacts scalability, performance, and reliability

The Gigaspaces Architecture A single model for full life cycle enterprise systems

From J2EE to XAP Component J2EE XAP Persistency JPA Hibernate, JPA Messaging JMS,MDB JMS, Polling/Notify Container , Native Messaging API Security JAAS, SSL Spring Security, SSL Web Session Management HttpSession HttpSession (via Jetty) Transaction Management JTA Spring Transaction via Jini Transaction Manager Data Access JDBC , Session Bean, Entity Bean JDBC, Space, JPA Remoting EJB, IIOP, RMI Spring remoting over LRMI Web Servlet, JSP Servlet, JSP (via Jetty) Packaging and deployment ear , war jar , war Contexts and Dependency Injection JSR 299 Spring IOC System Management JMX JMX , SNMP, Native Admin API Java Naming and Directory Service JNDI Jini Lookup Service

Scope of this session…..
Space Based Architecture
Scaling
Web Application Deployment
HTTP Session Management
Remoting
Implicit Map Reduce
Messaging and Processing
Polling and Notify Containers

Space Based Architecture – Scaling Diagram 1. Car wash, the tier based way: a different warehouse for each step in the process.

Space Based Architecture – The Unit System Diagram 2. An all-in-one "washing unit" containing soaping, watering and drying services.

Space Based Architecture – Multiple Units Diagram 3. Scaling the system by adding more "car washing units"

Space Based Architecture – A GigaSpaces Processing Unit Diagram 4. A Processing Unit with 3 services collocated with a space.

Example Set 1

Web application Deployment
GigaSpaces support WAR files deployment natively.
- JSP , servlet
WAR files instantiate Jetty transparently.
- Popular open source web engine used with large scale systems
Port management handled transparently.
Web application scaling handled transparently .
HTTP session replication handled transparently .

HTTP Session Management

Example Set 2

Remoting
GigaSpaces Remoting allows direct invocation of remote services in synchronous and asynchronous manner .

Remoting
GigaSpaces Remoting supports parallel invocation of multiple service instances.
- Implicit map-reduce
The First phase involves the Service invocation The Second phase involves reducing the results retrieved from the Services

Example Set 3

Messaging and Processing - Polling Container
A JMS Queue equivalent consumer
Support One to One messaging model
Write

Example Set 4

Messaging and Processing – Notify Container
A JMS Topic equivalent consumer
Support One to Many messaging model
Write

Example Set 5
