E.ON is one of the UK’s leading power and gas companies, generating electricity, and retailing power and gas. BJSS worked closely with E.ON to understand and migrate its Microsoft base services, including Windows, to Azure. This crucial migration provided the basis for future services and a model for providing integrated hybrid on-premise and Azure IaaS based solutions. BJSS also integrated Windows and SQL with back end services in addition to a complete deployment modernisation which has provided E.ON with a process for Azure migration.
