Quick answer
This cloud infrastructure interview question asks you to design a multi-cloud disaster recovery orchestration platform. Aim for a design that runs reliably and securely in the cloud at a sensible cost, then explain the services, regions, deployment and trade-offs. Interviewers want to see how you balance reliability, security and cost.
The problem
Design an enterprise-grade Multi-Cloud Disaster Recovery (DR) Orchestration Platform. As organizations distribute their workloads across AWS, GCP, and Azure, they require an automated "control plane of last resort".
The platform continuously ingests health telemetry from enterprise infrastructure. When a catastrophic regional or provider-level failure is detected, the system must definitively confirm the outage (avoiding false positives), execute a complex, dependency-aware recovery runbook (a directed acyclic graph (DAG) of recovery tasks), and safely promote secondary environments in an alternate cloud provider.
What must a multi-cloud disaster recovery orchestration platform do?
- Telemetry & Failure Detection: Continuously monitor the health of managed infrastructure and reliably detect provider-level or regional outages.
- Fencing & Split-Brain Prevention: Before initiating a failover, definitively isolate (fence) the failing primary environment to prevent data corruption if network connectivity is restored mid-failover.

Questions people ask about this interview question
- Which design type is this question?
- It is a cloud infrastructure question. You design a multi-cloud disaster recovery orchestration platform and explain your choices the way you would in an interview.
- Is this question asked at entry level?
- It is marked Hard. It suits engineers preparing for senior interviews, where you are expected to drive the discussion and go deep on trade-offs.
- What should I cover first?
- Start with the workloads, the availability target and the security and cost limits. Agree on scope with the interviewer before you design anything.
