Lift and shift is a reasonable first step. It becomes a problem when it is mistaken for the destination: the same architecture running on rented infrastructure, often at higher cost and with the original constraints intact.
1. Decide what each workload is for
Retain, rehost, replatform, refactor or retire — the right answer differs per workload and depends on business criticality, change frequency and cost profile. A single migration strategy applied uniformly wastes effort on systems that should have been retired.
2. Cost control is an engineering practice
Rightsizing, autoscaling, storage tiering and clear tagging deliver ongoing savings. Without cost visibility built into delivery, consumption rises quietly and the business case degrades.
3. Resilience must be designed, not assumed
Cloud availability zones do not automatically make an application resilient. Recovery objectives, failover testing and dependency mapping determine whether the platform holds under failure.
4. Automate the platform, not just the migration
Infrastructure as code, standardized pipelines and policy guardrails are what turn a migration into a sustained improvement in delivery speed.
Sequence for value
Modernize the workloads where change is frequent and cost is high first. Those deliver the clearest return and establish the platform patterns everything else can adopt.
