Today’s enterprise IT organization is faced with an interesting dilemma – the need to scale for business growth but limited or no space for data-center expansion. Provided below is a link that highlights the challenge data-centers in London are facing – lack of space for expansion.

Gartner believes that green theme will become a decision criterion for IT over the next five years.
From an application design standpoint this can be addressed by looking into how much space hardware requires and the hardware footprint application software requires. Hardware vendors have addressed the space problem by migrating to blades architecture. Application software remains the long pole to this space problem. Not many software solutions are designed from a green standpoint. Most commercial software designed on the principles of n-tier architecture requires more servers than what would be optimal to deliver a business solution. Grid and virtualization software are a step in the direction of green-IT. However, future application design needs to answer the question upfront on how many servers would be required to meet certain scalability requirements. Both space and power consumption constraints would impose design considerations for application designers.
Power consumption is becoming an issue.
N-tier architecture is a design paradigm right out of computer science design classes – an elegant architecture that is modular and therefore flexible. However, most of these applications which are supposed to scale to hundreds of thousands of users and thousands of concurrent users solve the scalability issue by throwing hardware at the problem. This combination of the design principles of n-tier architecture and the needs for scalability leads to server sprawl and therefore an “environmentally unsustainable” IT infrastructure.
New application design should take into account both scalability and “environmentally sustainable” IT upfront in designing next-generation applications.
