Technical Requirements
• Performance and Scalability: services must be
able to serve an unlimited number of users 24/7.
Engroup must be designed to be able to run in
clustering environment effectively.
• Extensibility: components are designed with
loose coupling and high cohesion. Cost of
upgrading and extending must be minimal.

independent of the others. One module can be
changed without impacting any other one.

method level of service class.

High Level Architecture

method between
Client and Server are
AMF, HTTP
protocols.

modules could be
integrated with other
clients via REST.

Engroup Client Platform
• Platform is developed
based on eSoftHead
framework including
an extension of
Adobe Cairngorm
framework.
• Module architecture
follows MVC pattern.
http://www.esofthead.com

Engroup Client Platform (cont.)
• Platform manages
Module life cycle.
• Platform routes
messages sent from
one module to
appropriate client
channel that then
dispatches events to
listening modules. It
helps the module
loose coupling with
each others.

Engroup Client Platform (cont.)
• Platform and common
API are independent of
AIR library.
• Factory pattern is used
to separate logic code
between platform and
specific AIR API →
Engroup client can run
on both desktop and
web environment.

framework and Osgi platform (Equinox) as well.
• Platform packages many third-party Java
libraries as Osgi bundles:
– Apache libraries.

Engroup server by:

– API - using Enterprise Integration Framework Spring
Integration to implement publish-subscribe pattern to
dispatch messages to appropriate channels.

and clear
responsibility.

and implementation
into different
packages.
