Not all workloads respond the same way to cloud migration. Rightsizing helps you focus on where the economics are most attractive.
1. Nonproduction workloadsCompanies are often more likely to save when they migrate
nonproduction workloads (such as development, testing, and staging) because:
- Usage is more volatile, so these workloads benefit more from the cloud’s flexibility.
- They can help reduce software licensing fees tied to core processor counts, especially when you rationalize and downsize cores.
2. Nonvirtualized workloadsNonvirtualized environments typically gain more from cloud migration than already virtualized ones, because virtualization has already delivered some of the efficiency and flexibility that the cloud provides. Moving nonvirtualized workloads gives you more room to:
- Consolidate servers and storage.
- Eliminate overprovisioning and zombie servers.
- Align capacity more closely with actual demand.
3. Workloads with transferable licensesOrganizations that hold existing
Microsoft SQL or similar licenses that can be migrated to the cloud often see the highest savings, since they avoid repurchasing licenses and can still rightsize infrastructure underneath.
For CIOs and IT leaders, the practical takeaway is to:
- Start with a data-driven assessment of current usage (for example, using tools like AWS Migration Evaluator).
- Prioritize nonproduction, nonvirtualized workloads and those with transferable licenses.
- Use migration as a chance to rethink capacity planning, not just relocate it.
This approach helps you capture the financial upside of the cloud while building a more manageable hybrid environment over time.
