Marcus Aurelius, Roman Emperor and philosopher, wrote that the secret of all victory lies in the organization of the non-obvious. While he could hardly have dreamed of organizations as they exist today and the technology at their disposal, his opinion on the source of success is still relevant.

A key factor contributing to enterprise success is the use of Information Technology. IT is the bedrock in business infrastructure across the planet, invisible but ubiquitous. In this paper we discuss considerations influencing the organisation of IT components and stacks, how Cloud Computing and Virtualization fit in, and how underlying concepts can be exploited in Enterprise IT solutions.

IT Architecture : Key Characteristics
Organisations typically measure the value of IT in two ways : how it maximises returns and delivers competitive advantage, and how it minimises the cost of operations. IT environments delivering mission critical services need to be rapidly deployed, to solve a problem or fulfil a need quickly. The environment needs to be elastic so that resources can be scaled based on demand.
To control costs, deployed resources should be utilised optimally, while provisioning and management should be simple. Finally, Enterprise IT Architecture should incorporate standardisation of platforms to further reduce costs. Adoption of Open Standards and Open Source technologies magnify these cost savings. Some major characteristics of good IT Architecture therefore are

* Rapid Deployment
* Elasticity of Resources
