Space Based Architecture – Scaling

Diagram 1. Car wash, the tier based way: a different warehouse for each step in the process.

11

Space Based Architecture – The Unit System

Diagram 2. An all-in-one "washing unit" containing soaping, watering and drying services.

12

Space Based Architecture – Multiple Units

Diagram 3. Scaling the system by adding more "car washing units"

13

Space Based Architecture – A GigaSpaces Processing Unit

Diagram 4. A Processing Unit with 3 services collocated with a space.

Example Set 1

15

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.

16

HTTP Session Management

Example Set 2

18

Remoting

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

19

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
