Rightsizing Lab
Right-sized instances, backed by real performance data.
Rightsizing Lab recommends the instance, node or database size that fits how a workload actually runs. It shows CPU, memory, disk and network for the current size and projects the same load onto the recommended one, so nobody has to guess.
What it does
Built for the engineers who make the change, and the finance team that checks it.
Headroom you set
Choose a target such as p95 CPU under 60 percent. Recommendations never cross the limits you define.
Family and generation moves
Suggestions include moves to newer generations and Graviton or AMD families where the workload is compatible.
Kubernetes requests
Pod CPU and memory requests compared with actual use, and node pool shapes that pack workloads more tightly.
Managed databases
RDS, Azure SQL and Cloud SQL sizing based on CPU, memory, IOPS and connection counts.
Projected performance
A chart of the same 14 to 30 days replayed on the recommended size, with peaks highlighted.
Ready for change review
Each recommendation exports as a ticket with the evidence attached for your change process.
How it works
Rightsizing Lab, step by step.
Good to know
- Recommendations respect your headroom limits
- Peaks and seasonality are part of every check
- Savings use your negotiated pricing and discounts
- Nothing is resized automatically
- 01
Metrics are gathered
CPU, memory, disk and network metrics are read for every candidate. Memory needs the agent you already run, such as the CloudWatch agent.
- 02
Sizes are compared
The current shape is compared with every viable size and family in the same region, using your pricing.
- 03
Load is projected
Historical load is replayed on the candidate size to check that peaks stay within your headroom rules.
- 04
Change is planned
You get the target size, expected saving and a rollback note. Your team schedules the change.
Questions
About Rightsizing Lab
What if memory metrics are missing?
We mark the recommendation as CPU-only and lower its confidence. You will see exactly which metric is missing and how to enable it.
Do you consider reservations already bought?
Yes. A resize that would leave an existing reservation unused is flagged, so you can time the change with the commitment.
