ProsperOps automates Savings Plans portfolio management, and it fits best when your compute baseline is stable and well understood. As of June 2026, AWS Compute Optimizer includes 32-day lookback for cyclic workloads and Graviton migration paths. Run those recommendations before enabling autopilot.
Engagement shape we commonly see: a mid-market SaaS, stable EC2/EKS compute after a recent migration, ProsperOps enabled immediately, effective savings rate drops after a Graviton refactor because the SP portfolio no longer matches the new baseline.
Teams that enable autopilot without a plan over-commit after a migration or under-commit during growth.
This guide covers when to enable ProsperOps, what to fix first, and how to pair automation with architecture work.
What ProsperOps does well
- Automated Savings Plans purchases and exchanges
- Risk-adjusted commitment strategy across compute families
- Integration with AWS billing and Organizations
- Reporting on effective savings rate (ESR)
- FinOps Foundation-aligned commitment management
What ProsperOps does not do
- Remove NAT Gateway or cross-AZ waste
- Rightsize EC2, Lambda, or EKS before commitment
- Stabilize tagging for allocation
- Execute Graviton migrations or serverless refactors
- Guarantee savings if baseline compute is mis-sized
Autopilot needs a plan: model the baseline, stabilize the architecture, enable automation, then review quarterly.
Pre-flight checklist (before enabling autopilot)
1. Baseline stability (4 to 6 weeks of clean data)
- No major migration in flight (EC2 → Lambda, x86 → Graviton, datacenter exit)
- Idle resources removed (cost pitfalls: idle resources)
- Rightsizing reviewed via Compute Optimizer
- Dev/test schedules or shutdown policies in place
2. Commitment portfolio design
- On-Demand vs Spot vs SP split documented per workload class
- 60 to 80% of stable compute covered by SP (FinOps Foundation guidance)
- Burst/workload variance identified; keep On-Demand headroom
- Graviton migration plan if significant x86 remains
3. AWS native alignment
- Savings Plans recommendations reviewed in Cost Explorer
- RI legacy portfolio inventoried (convert or let expire deliberately)
- Payer account billing alerts configured
4. Enable ProsperOps
- Read-only + purchase-scoped IAM role per ProsperOps docs
- Stakeholders: finance + platform + engineering sign-off on risk tolerance
- ESR target defined (FinOps consulting engagements typically target 25 to 35% average savings on covered compute)
Post-enable operations
| Cadence | Action |
|---|---|
| Weekly | Glance ESR trend; flag architecture changes in sprint |
| Monthly | Reconcile ProsperOps actions vs Cost Explorer SP utilization |
| Quarterly | Full cost optimization cadence; reassess baseline after major releases |
| After architecture change | Pause autopilot; re-baseline 30 days |
When to add FactualMinds
Commitment Strategy Workshop (1 week):
- Baseline modeling from CUR
- Architecture stability assessment
- SP portfolio design document
- ProsperOps enablement with guardrails
- Handoff runbook for quarterly review
FinOps Foundation Build if tagging, NAT, or EKS costs undermine commitment accuracy.
What to do this week
- Pause autopilot if a major architecture change shipped in the last 30 days.
- Export CUR and validate stable compute baseline before re-enabling.
- Review Compute Optimizer Graviton recommendations, and migrate before locking SP coverage on x86.
