Rightsizing Cadence

How often to rightsize.

Overview

Rightsizing cadence regularly reviews instance sizing against actual utilisation. Initial sizing is the easy part; the cadence of review is what preserves cost discipline as workloads drift over months and quarters.

• How often to rightsize. Per-quarter rightsizing review; the cadence matches the rate at which workloads drift.
• Per-quarter review. Per-quarter instance utilisation review; surfaces over-provisioned and under-provisioned instances.
• Per-instance right-size. Size adjustment per instance; the action that follows the review.
• Reserved capacity refresh plus accountability. Per-year reserved purchase reflects the new baseline; per-team cost surfaces accountability.

The approach

The practical approach: quarterly review, automated rightsizing where supported, annual reserved capacity refresh, per-team accountability, documented policy. The team’s discipline produces sustainable cost instead of reactive cost-cutting.

• Per-quarter review. Per-quarter utilisation review; the cadence catches drift before it becomes a CFO conversation.
• Automated rightsizing. Per-instance auto-rightsize where supported; reduces manual work; the action follows the data.
• Reserved capacity refresh. Per-year reserved purchase; the new baseline informs the next commitment cycle.
• Per-team accountability. Per-team cost; the team that consumes is the team that sees the bill.
• Document the policy. Per-team rightsizing policy committed to the handbook; supports operational reviews.

Why this compounds

Rightsizing cadence discipline compounds across quarters. Each review captures savings; the team’s cost maturity grows; the bill stays linear with usage instead of compounding with drift.

• Better cost efficiency. Right size matches workload; capacity follows demand without paying for unused headroom.
• Better operational fit. Right cadence catches drift; the next quarter starts from a tuned baseline.
• Better culture. Cost awareness becomes part of operations; the team owns the cost it generates.
• Institutional knowledge. Each review teaches workload patterns; the team’s capacity engineering muscle grows.

Rightsizing cadence discipline is an operational discipline that pays off across years. Nova AI Ops integrates with cost telemetry, surfaces patterns, and supports the team’s cost discipline.
