Learning Outcomes

On successful completion of this module students should be able to:

Demonstrate specialised skills to achieve the reuse of design expertise through the application of software design patterns and particularly in the context of designing and building distributed applications.

Describe the generic architecture of multi-tier, distributed applications.

Assess critically the appropriateness of various Internet-based communication technologies to solving the communication requirements of a variety of distributed applications.

Build a simple, multi-tier distributed application that employs the use of appropriate testing techniques, design patterns and communication technologies.

Demonstrate a critical appreciation of Cloud computing.

Demonstrate a critical appreciation of design issues encountered when developing multi-tier, distributed applications.

Demonstrate cognizance of the security requirements of distributed applications.


Teach best practice in building web applications; enterprise design patterns; support for business-to-business application interoperation; security and in the context of the cloud. Give students the opportunity to build a distributed application that employs best practice in these areas. Make students aware of the opportunities and limitations of various distribution technologies. Allow students to demonstrate their ability to apply such technologies.

Brief description

The majority of the software developed today is distributed. It is important that students are given the opportunity to build a distributed application that employs best practice: agile methodologies taught in other modules, building web applications, enterprise design patterns, support for business-to-business application interoperation, security and deployment to the cloud.


1. Introduction to building Internet-based applications.
General introduction to the module. Distributed application architectures: client and server (n-tier architectures).

2. Building a simple web application using a web application framework such as Ruby-on-Rails. The web application framework and its support for the MVC enterprise design pattern and for object-relational mapping.
Introduction of a running example used during some of the module.

3. Internet-based communication technologies and architectures.
Support for interoperability by various technologies: e.g. sockets, object-based communication, message-based communication, XML-RPC and Soap-based web services. Representational State Transfer (REST) web services. Design issues. Application of web services to the running example. Ajax concepts and application.

4. Cloud computing.
Overview of the Cloud and deployment to a popular Cloud environment.

5. Testing Web-based applications.
Use of appropriate tools and techniques, such as behaviour-driven techniques.

6. Security of distributed applications.
Including cryptography, symmetric and asymmetric algorithms, Transport Layer Security protocol, mitigating web hacking attacks (code injection attacks), single sign-on. The Java Security Model, and the CERT Oracle Secure Coding Standard for Java.
