Enva’s growth has been fuelled by a number of acquisitions of targeted businesses across the UK and Ireland, but with each new purchase the complexity and scale of their business infrastructure has grown. Whilst centralising all services was an option, this would have taken time and introduced significant risk, so Enva have been managing a disparate architecture of multiple infrastructure elements spread across the UK and Ireland.
A project to reduce the risk of this widespread infrastructure was needed, so Enva turned to Waterstons, a long-term technology partner with in-depth knowledge of the business and its infrastructure, to help.
Waterstons engaged with Enva’s IT team, their operating units, and a multitude of different suppliers to create, in partnership with them, a wide-ranging plan for delivery of the project. Waterstons proposed a new Nutanix hyperconverged infrastructure, which would allow the myriad virtual servers in use to be migrated to a single platform; but with over 100 virtual machines (VMs) in use across Ireland, England and Scotland, this was going to be no small task.
Waterstons managed this complex project in partnership with Enva, ensuring progress stayed on track, and to quickly identify and mitigate risks and issues as they arose; all the while co-ordinating the activities of different suppliers to ensure a smooth transition to the new architecture.
During the process of migration, Waterstons took the opportunity to rationalise and standardise Enva’s server infrastructure. A c30% reduction in the number of servers and the removal of end-of-life server operating systems was achieved, not to mention reducing environmental impact and running costs via a significant reduction in power usage from >12kW to under 3kW. The migrations and testing were undertaken without incident, bringing all the servers onto a single Nutanix cluster to service the entire organisation; with a concomitant reduction in infrastructure complexity which will lead to reduced support cost going forward.
With room to grow in the future, Nutanix provides a stable platform for the business now and going forward, and will greatly simplify the integration of further infrastructure for organic growth, or should any more acquisitions take place. With so many systems to migrate, it’s no surprise that previously there had been a wide variety of resilience and backup solutions in place individually across the estate. This project offered the opportunity to consolidate all the disaster recovery capability in a single backup with globally defined recovery point and recovery time objectives (RPO/RTO).
The new resilience and backup solution uses Veeam Backup and Replication to bring all the backups together in a single unified strategy, with ‘air-gapped’ backups used to ensure recoverability and security for the business’s critical data and services.
Covering on-premise and Azure cloud-based systems, the backup further employs Veeam for Office 365 to ensure even data in Microsoft’s public cloud infrastructure is securely backed up and recoverable.
With hyperconverged infrastructure, supported directly by Nutanix, and the new backup solution deployed, tested, and successfully made live, Enva are in a strong position to benefit from a single RPO/RTO which ensures they are able to bring critical systems and data back online well within 24 hours from a failure point. With Enva’s growth continuing, the stable, scalable platform will ensure their business is able to thrive well into the future and beyond.
