A business-first guide to workload assessment, migration sequencing, security and operating model design.

Classify workloads by value and risk
A cloud programme should not start by moving everything. Map the applications, data dependencies, users, uptime needs, constraints and cost drivers. This shows which systems are good candidates for a quick move, which need modernisation and which should stay where they are for now.
The right sequence balances visible progress with safety. It also avoids disrupting an essential system simply because it is technically possible to migrate.
Create the landing zone before the migration wave
Identity, networking, logging, backup, encryption, cost controls and incident access should be designed before workloads arrive. A well-defined landing zone gives teams a repeatable foundation instead of a collection of one-off environments.
This is where cloud governance becomes practical: clear account structure, least-privilege roles, tag standards, monitoring and accountability for spend.
Plan the operating model, not just the cutover
After migration, someone must monitor, patch, improve and manage costs. Define ownership and service expectations early, including how internal teams and external partners will work together.
Cloud creates flexibility, but it also makes disciplined operations more important. The goal is a platform that is easier to change safely over time.
