Resilience Without Cloud Dependency
Healthcare organisation, North America
An active-passive multi-cloud architecture reduced concentration risk and protected the continuity of critical healthcare services against regional cloud failure.

The challenge
What was going wrong
A healthcare organisation in North America required a multi-cloud resilience strategy to reduce dependency on a single cloud platform and protect the continuity of critical services. It operated sensitive and business-critical workloads that could not tolerate extended disruption, requiring high availability, cross-cloud recovery, protection against regional cloud failure, healthcare privacy compliance and defined recovery objectives.
Our approach
What we built
- 01
Classified applications by business criticality, data sensitivity, Recovery Time Objective, Recovery Point Objective, platform dependencies and cross-cloud compatibility.
- 02
Designed a primary active environment and a secondary passive recovery environment with secure inter-cloud connectivity, identity federation, data replication, configuration consistency and central monitoring.
- 03
Developed failover sequencing, application recovery groups, DNS transition, network activation, data validation, business-testing procedures, failback planning and recovery runbooks.
- 04
Incorporated healthcare-data controls, access governance, encryption, logging, audit evidence and periodic DR testing.
The outcome
What changed
- Reduced concentration risk and stronger business continuity.
- Defined and testable recovery procedures and improved visibility of application dependencies.
- Better cross-cloud governance and enhanced leadership confidence.
- Greater protection of critical healthcare services and a scalable resilience model for future workloads.
