We design for the failure modes the workload actually has. For most growth-stage systems that means active-passive across two AWS regions with replicated state and a documented failover runbook — not active-active by default, which often costs more than the downtime it prevents. We size the redundancy strategy to your real RTO and RPO, not a generic best-practice template.

It depends on workload complexity, regulatory constraints, and how clean the existing system is. A focused workload (one service, one database) can move in 4–8 weeks. A multi-service modernization with refactoring runs 3–6 months. We use the AWS 6R strategy to pick the right path per workload — Rehost, Replatform, Refactor, etc. — and migrate in phases so the legacy system stays operational throughout.

Every engagement starts with a discovery sprint — mapping your stack, constraints, and outcomes. From there we agree on scope and shape: fixed-scope project, embedded team, or staffed augmentation. Post-launch, we hand off the runbooks and operating model so your team can run what we built. Long-running managed operations are a separate conversation, not a default included service.
