Most failed cloud migrations aren't failures of technology — they're failures of sequencing. Moving everything at once, without a clear rollback plan, is where most of the risk lives.
Start by classifying workloads: what's stateless and easy to move, what holds critical state and needs careful data migration planning, and what's genuinely legacy and might be better retired than migrated.
Migrate the lowest-risk, highest-learning workload first. This gives your team real operational experience with the new environment before anything business-critical depends on it.
Invest in monitoring before migration, not after. Knowing what 'normal' looked like on the old infrastructure makes it far easier to spot problems on the new one quickly.
Key Architectural Takeaway
Enterprise systems achieve long-term resilience by establishing clear domain boundaries, decoupling business logic from external frameworks, and automating end-to-end regression testing from Day One.
