The driving forces behind a move to cloud computing can vary immensely. Some research carried out last year shows that the public sector's most popular IT objective when deploying cloud services is dealing with end-of-life technology, closely followed by the replacement of legacy systems. The private sector however seems more focused on the cloud for cost-cutting. It may be reassuring then that the public sector is improving its IT infrastructure, but some organisations fail to secure the full benefits.

These can go beyond tactical wins such as boosting productivity and reducing risk. Cloud computing can help an organisation to make bold changes and innovate, not just in IT infrastructure, but across the organisation. By moving data and operations into the cloud it is possible to make significant changes to processes and improve growth strategies, offering long term benefit. It can also pave the way for future business developments by enabling easier deployment.

Whatever your reason for moving to the cloud, the biggest challenge exists in managing the transition. Whether you are replacing old technology or innovating, there are some fundamental steps that will create a successful transition.

Devise a strategy: Establish at the outset what your end-point should be: what do you want the cloud to deliver? Whether you select an off-the-shelf or bespoke cloud solution, having established one that suits your needs, your route to the cloud should be shaped accordingly.

Internal sponsorship: Our research indicates that a lack of internal sponsorship is the most common reason for delaying transition to the cloud - so said 40 per cent of respondents. Therefore, the IT team must devise and agree a solid business case with senior management. The case must explain how cloud adoption will help to progress the organisation and help to maintain a competitive edge. Support from all areas of the organisation will help to ensure that the implementation stays on track.

Select the supplier: With a clear understanding of what you require from a cloud solution, you need to identify a supplier that can help to achieve it. There may be a niche cloud provider specialising in what you need. Alternatively, you may find that large provider could best meet your needs. Don't forget to work out if you need a public or private cloud to deliver your plan and don't overlook factors such as the budget, the types of data, and the security that your business expects.

Due diligence: A cloud provider that isn't reputable or credible should be avoided. Ask for business accreditations and references and be sure that they belong to the right procurement frameworks if this applies. An ideal cloud provider should have a dedicated security or assurance function; establish how they are audited and if they are validated externally to determine standards compliance.

The exit strategy: You won't be using the same provider forever, so securing a clear and well understood exit route is essential. It should take account of how many suppliers make up the service and what format the data is in so that you can access your data successfully. Base your exit strategy on an open source service that offers full control and data ownership.

With the transition complete the difficult part is over. Provided your organisation is cloud-friendly your new solution should receive internal support. Having chosen the most suitable supplier you can be certain that your solution will be adequately maintained and secure.

Managing this transition to the cloud, whatever the reasons, will enable IT departments to view their cloud service as the perfect time to start innovating across all areas of its operations and beyond. NC
