Cloud Migration Without a Big-Bang Rewrite
Representative cloud modernisation pattern
A practical example of planning cloud change around business continuity, dependency risk, ownership, and cost visibility.
Challenge
A critical estate needed modernising, but downtime, compliance, dependency risk, and unclear ownership made a simple migration plan unrealistic.
Approach
The safer route is to define the target environment, map dependencies, move services in bounded batches, validate rollback paths, and introduce cost governance early.
Impact
The useful outcomes are better sequencing, clearer ownership, visible costs, and less uncertainty around the systems the business depends on.
