Viridian Housing


Viridian Housing increased flexibility of working environment with move to a Cloud-based IT model.


Wide Area Network & Virtual Data Centre.

Viridian, a UK social housing association which supports over 30,000 residents in England, with 850 employees, wished to move away from its dependence on internal systems to a Cloud-based IT model.

By transitioning into the Cloud, Viridian stood to benefit from a more flexible working environment, Viridian could therefore better control IT costs and the ability to drive greater efficiencies. Exponential-e’s carrier-class Network provided the robust Network infrastructure and its Virtual Data Centre was used to build Viridian’s high performance Cloud environment.


In order to reduce expenditure and align IT costs with the size of the business, Viridian required the transformation of its data centre and service infrastructure. Historically, Viridian was dependent on a cost driven approach to its infrastructure with little flexibility. As a result, the company was unable to adapt its IT skills and capabilities to match its new contract wins and business growth. To improve IT efficiency, Viridian needed IT expenditure to move to a pay-by-usage model.

Transitioning to a Cloud environment required careful consideration and assessment of business needs and existing infrastructure. Viridian’s existing in house Data Centre was not suitable to meet the demands of the growing business. With this in mind, Exponential-e was challenged with migrating its critical applications to three separate data centre locations.

Additionally, with an increasing demand for 24/7 customer service, Viridian required the flexibility to allow its call centre staff to work remotely. Moving services to the Cloud needed to ensure that Network reliability and availability of services were not compromised.

Therefore, Exponential-e were challenged with meeting security and disaster recovery requirements. Phil Copperwheat, Head of Systems at Viridian, comments: "We needed to more closely align IT costs to the business size and shape. This need informed our decision to move to a more flexible, Cloud-based service model. Exponential-e’s solution has been critical to enabling us to deploy the right technologies to meet our business goals"


To gain control over IT costs and the ability to drive greater efficiencies, Exponential-e moved Viridian's critical applications to a Cloud environment, providing the company's IT team with peace of mind that they had a robust and reliable Cloud platform able to provide the level of service required around the clock. Exponential-e's expert Cloud team ensured the deployment of the correct technology, providing invaluable advice on this transition and worked closely with Viridian's in-house IT team. People, processes and IT assets were all considered and the end Cloud solution was designed to best meet the future needs of Viridian whilst taking into account existing capabilities and resources. Many of Viridian's critical applications, like email, were completely rebuilt and an entirely new application environment created in the Cloud.


By opting for a hybrid model that extends the functionality of existing internal IT systems into the Cloud, Viridian ensured it had the time needed to move into the Cloud in a controlled way. This incremental on-boarding approach to Cloud migration allowed Viridian to balance its expenditure on internal IT and Cloud Services.
As the expenditure on internal IT systems was reduced and equipment retired, more investment could be made in new Cloud services. Legacy applications that made more limited demands on processing and storage capabilities could be left running on existing equipment, while more demanding business services could be hosted in the Cloud, effectively extending the life of existing systems. By transitioning into the Cloud Viridian’s employees also benefit from a more flexible working environment. By paying for services only as needed, Viridian can ensure that costs are controlled and service experience is maintained, ensuring that Viridian remains agile and responsive.
