Architectural Consideration for application to be deployed over Cloud

Cloud computing is new way of deploying a application. This deployment topology brings in its own pleasant moments and surprises. For an architect and designer Cloud opens up new avenue and dent into capacity planning. Now a programmer of application to be deployed on a cloud can spread over logical hardware at run time without involvement of any hardware and network person’s involvement.

While architecting a application for Cloud few aspects to be taken into consideration.

1. Scale: Application to be deployed on Cloud can grow and shrink dynamically based on load and can be controlled programmatically.
2. Coupling: Application to be developed in highly loosely coupled. Here SOA principles can come handy.
3. Clustering and Virtualization: Clustering and Virtualization is inherent to cloud architecture. These two aspects must be considered in detail while architecting an application.
4. Failure: Clod application must be architected to fail in parts, autonomic and fault tolerant fashion to get full benefits of Cloud architecture.

These are the considerations specific to Cloud. There could be several other which we can learn with experience over Cloud.
