Creating resources in another region does not guarantee continuity. The decision depends on which faults need to be covered, how long the operation can wait, and what data needs to be available.
How to evaluate this decision
Map application, bank, files, identity and external services. Define recovery objectives with those responsible for the business before choosing architecture. Replication can carry errors and does not replace backup. A more complex solution also requires operation and testing; Maintaining an environment that no one can activate may offer little practical protection.
Criteria for comparing proposals
- Scope: identify unavailability scenarios and dependencies that remain shared.
- Data: define update and tolerable loss according to the operation.
- Activation: document decision, execution, validation and return to the main environment.
A scenario to discuss with the supplier
Hypothetical example: the alternative application works, but depends on the same unavailable authentication service. The plan needs to consider this dependency to represent the user's full path.
What to validate upon delivery
Carry out an authorized test with controlled criteria and environment. Measure time, available data, and obstacles, distinguishing demonstrated ability from estimation.
Prepare the conversation about the project
Bring Quantum9 criticality, dependencies, and recovery objectives. The design must compare alternatives proportional to the risk, without promising availability that the architecture and operation do not prove.
