AWS Case Study - NHS Business Services Authority


NHS BSA is a Special Health Authority that provides a number of UK-wide services for the NHS including all UK prescription payments and administering the pensions for all NHS staff.


In 2016, frustrated by its incumbent supplier of traditional hosting where six month delays in building servers were possible, it decided to move to the cloud and use a DevOps approach.

BSA wanted to find an infrastructure supplier who could provide them with unfettered access to cloud services from any supplier. The provider also needed the public sector experience and technical expertise to design, build, secure and operate hosting using a collaborative approach. Once a partner had been selected, they wanted to deploy multiple applications at speed.

Why Arcus & AWS?

As an AWS Managed Services Partner, the quality of our managed service is rigorously assessed every year by external assessors. BSA also needed a supplier with public sector experience.

Arcus was the the first partner in Europe to gain the AWS Public Sector Competence. BSA also liked the simplicity of Arcus’ support pricing which makes it easy to predict costs and gain business case approval.

BSA wanted to remain ‘cloud agnostic’ by using tools that can deploy to several cloud providers so we worked with them to provide secure environments on AWS that would work with their standard toolset.


  1. Within five months of procuring Arcus, BSA had a series of secure, live AWS environments with N3 connectivity and deployed the first wave of over 80 applications
  2. The lead time for a new server to be built has dropped from over six months to three minutes
  3. Initial indications show that the new infrastructure will be up to 75% cheaper than its predecessor
  4. BSA now benefits from a shared responsibility model where AWS provides low-cost, resilient infrastructure, Arcus manages, monitors and ensures security, and the BSA team builds and deploys applications

“Ever since our first engagement with Arcus it has been a positive experience and the relationship continues to grow from strength to strength. Our Cloud environments were brought online very quickly and despite our exacting requirements, Arcus has delivered. We are excited about the benefits of moving to the Cloud and have confidence that we will supported through this journey by Arcus.”
