Multi-cloud is often framed as a strategy choice, but one of the strongest multi-cloud use cases is disaster recovery.
The logic is straightforward. Disaster recovery exists for the scenarios where your primary environment is unavailable or compromised. If production and recovery share the same provider and the same trust boundary, then you still carry concentration risk.
This blog explains why multi-cloud disaster recovery is growing in relevance, why Azure-first organisations may use AWS for recovery, and how disaster recovery becomes a practical starting point for multi-cloud strategy.
A few years ago, many organisations treated same-cloud recovery as ‘good enough’. Today, three pressures are changing that:
1. Cyber incidents increasingly target identity and backups
2. Business expectations for continuity have risen
3. Boards and executives are more aware of systemic risk and vendor concentration
The goal is not to abandon Azure. It is to ensure that recovery capability is independent enough to survive the same category of incident.
When production and recovery depend on the same provider, a platform-wide event can impact both.
These events may be rare, but the entire purpose of DR is to handle rare, high-impact incidents.
Boards understand this instinctively. If a risk is systemic, mitigation must be systemic. Multi-cloud recovery breaks that dependency.
A common objection is that multi-cloud adds complexity. That can be true if you run production across multiple providers.
Disaster recovery is different. In many designs:
- Production remains in Azure
- The recovery platform is maintained in a minimal state
- Recovery environments are activated during tests and incidents
This means you can achieve the risk reduction benefits of multi-cloud without running two full production platforms day-to-day.
Azure-first organisations often choose AWS for recovery because it provides:
- A separate identity and access model
- Mature object storage capabilities for immutable backup copies
- Elastic compute that can scale during recovery
- Network segmentation controls that support isolation
The recovery platform does not need to match production. It needs to be independent, reliable, and capable of running recovered workloads.
A cross-cloud DR approach delivers three outcomes:
1. Independent recovery
If Azure is unavailable or compromised, you can still restore and run critical services.
2. Stronger ransomware resilience
If the primary identity plane is compromised, the attacker does not automatically control recovery storage and recovery compute.
3. A foundation for multi-cloud strategy
The DR platform becomes an operational entry point into AWS. It creates governance patterns, landing zone capability, and hands-on familiarity.
Traditional multi-cloud adoption is often framed as a migration programme. That creates resistance.
Disaster recovery is different. It is use-case led. You build AWS capability for a specific purpose: resilience.
Over time, this can reduce friction for future initiatives such as:
- Workload portability
- Migration waves
- Optimisation and FinOps
- Modernisation
But the first step remains resilience, not migration.
Multi-cloud DR is most valuable when:
- Workloads are critical and downtime has a material cost
- There is strong cyber risk exposure
- There are governance requirements to reduce concentration risk
- The organisation wants a gradual path to multi-cloud capability
It is less valuable when:
- Workloads are non-critical and downtime tolerance is high
- The organisation cannot support any additional operational scope
In those cases, same-cloud recovery may be acceptable.
A sensible adoption path is:
Run a DR readiness assessment
Define RPO and RTO per workload
Select the right pattern - backup-only, warm standby, or hot DR
Build an isolated recovery platform
Test regularly and capture evidence
If you want to reduce single-cloud risk and improve ransomware resilience without forcing a migration decision, start with a DR readiness assessment and design an independent recovery platform.
