Your cloud, your way

We provide a range of innovative cloud-based services to both public sector and commercial organisations across a range of industries.

Whether you need a secure private cloud, public cloud or the best of both worlds with a hybrid cloud platform, we have the expertise to advise and implement a solution tailored to your needs.

Our cloud services can be scaled according to your business requirements with the capability to add resources without server upgrades or downtime.

Moving to a cloud based infrastructure allows better cost management and value as you move to a more predictable OPEX model, giving you maximum return on your investment. You gain access to a wider pool of expertise, strengthened security and agile technology without the significant upfront cost.

Disaster Recovery as a Service

In the event of a disaster, the time it takes to recover critical application and/or data can make or break your organisation. An effective business continuity and disaster recovery plan can streamline how you handle such a situation and can significantly reduce both data loss and reputational damage.

Infrastructure as a Service

We offer a full server hosting and operation service that covers the supervision and monitoring of backups, a tailored 24/7/365 support service, security management, software and patch management, and delivers inbuilt software assurance, allowing you to reduce the overhead of maintaining a modern IT infrastructure and enhance and extend your existing IT resource.

Software as a Service

We have developed unique hosted solutions for many of our business software systems, with Infor SunSystems, Pegasus, Qlik and Microsoft Dynamics NAV and CRM solutions being made available from our cloud infrastructure. In addition we can implement and support Microsoft Office 365 and Microsoft Dynamics 365 solutions.
