Cloud Computing

Cloud computing has become a key component in the delivery and management of information systems for many organisations. It offers flexibility, scalability and significant cost cases. Man companies which cannot afford large software implementation can access systems over the cloud using Software as a service. Additionally where demands on systems and servers varies and peaks such as Black Friday must be managed, cloud computing offers the ability to access computing resources on demand, and we do not have to service a large capacity in-house. But there are problems with cloud computing which need addressing, particularly around security. Procuring cloud computing requires and understand of current services and capacity, and identification of IT applications and services which would benefit and a definition of a business case.
