Cloud architecture & migration
Move the workload with a plan for what comes next.
Assess dependencies and migration risk, then move workloads through rehearsed cutovers and rollback gates.
- 1Prepare
Map dependencies and rehearse a restore
- 2Cut over
Move traffic with one authority for writes
- 3Verify
Run business checks before retiring the source
A successful cutover is more than redirected traffic
The fragile approach
Move the servers, then fix the dependencies
The application may start while authentication, scheduled jobs or financial interfaces still point to the old environment.
The intended approach
Move a verified operating system
Use a dependency register, runbook and acceptance checks that cover complete business workflows.
From implementation to ownership
What your team receives
Agree the scope and the acceptance evidence before delivery starts.
Dependency register
Identity, data, scheduled tasks and external interfaces required by the workload.
Included scope agreed before deliveryCutover runbook
Sequence, decision owners, validation and the last reversible checkpoint.
Included scope agreed before deliveryRecovery evidence
A rehearsed restore and verification of important business workflows.
Included scope agreed before deliveryAn implementation example
The migration ends when the business can operate
Plan identity, data ownership, integrations and rollback alongside infrastructure. Rehearse the cutover against representative workloads before changing the production path.
A migration with a return path
An Australian operations team is moving an application while keeping its existing integrations working.
A failure to account for
New writes arrive in the destination after the team has started reversing traffic.
Illustrative scenario, not a customer case study.
Cloud & platform engineering
Move the workload and its operating context.
Workload dependencies
Inventory applications, data stores, identities, scheduled jobs and external connections.
Cutover rehearsal
Test data transfer and traffic switching while keeping one authoritative writer for each record.
Operational ownership
Hand over access, recovery procedures, monitoring and cost responsibilities with the environment.
Often. Separate changes needed for hosting from product changes, and migrate in increments where data ownership and rollback remain clear.
