Guides
Get the most out of every reservation.
No listicles, no fluff — long-form guides that teach you exactly how Reserved Instance pricing, terms, and renewals work, so nothing you already paid for goes to waste.
Reserved Instances
The AWS Reserved Instance renewal playbook
The biggest, most boring discount in cloud has one silent failure mode: it doesn't renew itself. Here's what an RI actually is, why the renewal cliff catches even disciplined teams, and how to stop it happening to you.
Coverage
The Reserved Instance coverage playbook
Reserved Instances only save money if they're covering something real — and covering everything isn't the goal either. How to measure coverage, set a target, and keep it honest as your fleet grows from a handful of reservations to thousands.
Savings
The AWS Reserved Instance savings playbook
Every Reserved Instance is the same bet: pay some or all of it now for a lower rate later. Here's how term and payment option change that bet, how to read break-even, and why running the math pays for itself at any fleet size.
Comparison
Reserved Instances vs Savings Plans
Two different commitments, both sold as "reservations." Here's exactly what an RI locks in versus what a Savings Plan locks in, an honest head-to-head, and why the renewal cliff catches both the same way.
