The customer

Established in 1974, this UK local authority is the third largest metropolitan district by area in England. It has 69 elected councillors, and has responsibility for delivering public services to over 437,000 county residents.

The situation

  • Reduce footprint of server infrastructure across messaging, directory services and supporting applications
  • Leverage the flexibility of cloud in scale and performance
  • Achieve robust Disaster Recovery (DR) capability
  • Upgrade existing Exchange solution to facilitate the co-existence and migration

  • Deploy ADFS v3.0 as the identity provider in a resilient, highly available architecture
  • Deploy Azure AD Connect for directory synchronisation to Azure AD with DR standby

Outcomes achieved
