The role can only read. It cannot buy or change anything.
The engineer who owns the AWS account, the IAM role, and the architecture running on it. A missed renewal turns into a debugging session with your name near it, and a bad reservation becomes a purchase nobody remembers approving.
The engineer who owns the AWS account, the IAM role, and the architecture underneath it.
- You hold the IAM role everything else in this fleet depends on
- A reservation bought against the wrong family becomes your problem to explain
- Nobody assigned you renewal tracking, but the job landed on you anyway
Where this role gets blindsided
Same role, same three blind spots.
The leak
A role that can buy something you never approved
A tool that automates purchases can automate a mistake just as easily. If the connection role can act without a check, a bad recommendation becomes a bad purchase before anyone reviews it.
What Reserver does
Read-only by default.building · M4 The connection role only describes and lists what's running. It cannot start, stop, resize, or buy anything. A separate purchase role is on the roadmap, opt-in when it ships.
The leak
A commitment that outlives the architecture
You reserve a family today. The service gets rearchitected next year, and the instance it was reserved for is gone. The mismatch sits there until someone notices.
What Reserver does
Matching runs continuously. Reserver checks what's running against what's reserved on a schedule. When a family ages out of the fleet, its reservation shows up as uncovered. You see it before it becomes a silent write-off.
The leak
One more dashboard to maintain
Every tool connected to the account is one more thing to patch and to explain in a security review.
What Reserver does
One scan, one answer. Connect the role once. Reserver scans, matches, and recommends on its own, so there is no job for you to babysit.
The fee against the saving
Priced for your fleet size.
A renewal nobody put on a calendar ends up as a cost spike, and you are the one who has to trace it.
A renewal missed by 14 days runs about $92.
On Watch, catching it costs nothing.
Watch is free, so you keep all of the $10,530 a year.
A renewal missed by 14 days runs about $951.
A single prevented miss pays for about 6 months of Autopilot.
Saves about $105,300 a year. That is 59× Autopilot's fee, which is 2% of the saving.
A renewal missed by 14 days runs about $6,904.
A single prevented miss pays for a year or more of Scale.
Saves about $1,053,000 a year. That is 176× Scale's fee, which is 0.6% of the saving.
Objections
Straight answers for platform teams
Does the connection role need write access to anything?
No. It only calls Describe and List actions across the services Reserver covers. Nothing it does can start, stop, resize, or delete a resource.
What happens to a reservation if the architecture changes under it?
Reserver keeps matching reservations against what's actually running, so a reservation that no longer fits shows up as uncovered. Nobody has to remember to look for it.
Who gets paged if a purchase goes wrong?
Nobody today. The connection role is read-only and never purchases anything. A separate, narrowly scoped purchase role is on the roadmap, opt-in and revocable when it ships.
Does Reserver suit a small fleet and a large fleet alike?
Yes. A fleet with a few reservations and a fleet with thousands run on the same read-only role and the same daily scan. Only the plan changes, and the three case studies show one account at each size.
Proof, not a promise
Three accounts, read for your job.
Look for the renewal that slipped and the tier nobody reserved. Each account had at least one, and the cards show what it cost.
RDS · ElastiCache · EC2 · 1 account
One missed renewal and one tier never reserved. We priced both.
RDS · ElastiCache · EC2 · 6 regions
Twelve years of careful reviews still missed money between review dates.
RDS · ElastiCache · EC2 · 40 accounts · AWS Organizations
Each account looks fine alone. The loss shows only across all 40.
