Easy route to the cloud

We understand that not everyone is at the same stage in their transformation journey which is why we represent freedom of choice to the customers we serve.

We empower IT transformation for all public sector organisations, regardless of size or complexity of the infrastructure.

We offer our customers the same foundation to create and inspire change, opportunity to transform, move forward, consolidate infrastructure, and migrate to new platforms using a more efficient and cost-effective model.

Pay for what you use

Flexible, transparent pricing with minimum volume commitment and contracts you can terminate at any time.

Reliable migration services and onsite support

Our migration services can help you move from your existing data centre with minimal downtime and maximum security.

We then offer a full range of onsite support services, designed to complement the day to day running of your data centre.

Leverage lessons learnt

In 2013, the UK government introduced the Cloud First Policy, urging all public sector organisations to transition their services to the public cloud. Many have found this ‘complex and challenging’.

We help customers determine the best solution for their data and migrate relevant applications to the public cloud. We then continue to provide the optimal location for remaining on-premise equipment, as recognised in the updated Cloud First Policy.

This approach is a key part of how we support our customers through their digital transformation journey.

Accurate, meaningful reporting

As an integral part of our service, we provide you with valuable insights to optimise your data centre operations and social values, empowering better, more informed decisions.

These can include electricity usage, carbon usage (for emissions reporting) and water usage (for sustainability reporting).
