AWS cost optimization that actually gets implemented.
Hands-on optimization across your whole stack, done by us, following your process. Config changes, migrations and cleanup that need next to nothing from your engineers.
Hello, this is Cristian Magherusan-Stanciu, a former AWS Specialist Solutions Architect for Spot and Graviton, and I built AutoSpotting. I help teams spending upwards of $100k/month on AWS.
What we optimize
We cover the usual compute, container, storage and networking services, and many more. On compute and containers that means EC2, Lambda, EKS, ECS, Fargate and EMR, plus the managed services that run on EC2 under the hood: RDS, ElastiCache and OpenSearch.
For each of these we apply the strategy that fits the workload: instance type selection, right-sizing, autoscaling and elasticity, adopting Spot instances, migrating to Graviton, and buying Savings Plans and Reserved Instances sized to what you'll actually run.
On storage we pick the right S3 storage class, add lifecycle policies, and right-size EBS volumes and their provisioned IOPS and throughput, including the EBS volumes behind RDS. On networking we cut inter-AZ traffic, add VPC endpoints and PrivateLink, and improve the CloudFront cache ratio. Storage, logging and networking are worth calling out because no Savings Plan or Reserved Instance ever covers them: they get cheaper only when someone optimizes them.
Much of this isn't only about cost. Teams routinely see better performance after the same exercise, most visibly when adopting Graviton, using VPC endpoints and improving the cache ratio.
What it costs
Most teams start with one scoped project: an agreed set of implementations for a flat fee, with the expected savings named before we begin. If it works, it becomes an ongoing monthly retainer.
We work three ways: a scoped project for a flat fee, an ongoing monthly retainer, an agreed block of engineering hours priced case by case against your scope and what you need, or a share of the savings, typically 10% to 30% sized to the footprint under our scope and billed per change for its first 12 months. On the savings-share model, a change that saves nothing isn't billed. All three can go through AWS Marketplace, so the money comes out of the cloud budget you already have. On any model, savings are measured automatically from your real before-and-after billing data, per change, so what you pay always ties back to the actual bill.
It typically costs less than a FinOps SaaS subscription, and on the savings-share model we'll agree a cap if you want one.
How the engagement works
Low-risk, reversible changes, shipped through your own review and rollout.
- 1
Discovery call
With the NDA and paperwork signed up front, a short call to walk through your stack and your goals, so the work starts on the right priorities.
- 2
Read-only access
You grant scoped, read-only access first, so we can analyze your setup in detail. No standing admin, minimal IAM, expanded only when a change needs it.
- 3
First changes in your repo
We open pull requests in your repositories, usually within days of getting access. They follow your process and stay low-risk and reversible.
- 4
Weekly sync
A 30-minute weekly sync with one engineer on your side. That plus occasional PR reviews is your team's entire time investment.
- 5
First measured savings
Changes land and the effect shows up on your bill in the same billing period.
Where the savings really come from
Commitments are the easy win, an afternoon of work, but they only ever cover part of the bill. Most of what we find is small: a few hundred dollars a month each, low-risk, with no migration project. Individually, none of them justify pulling an engineer off the roadmap for half a day to research, execute and verify, which is exactly why they never get done.
The arithmetic works for us, because we automated it.
Every change is prepared with help from tooling we built and battle-tested over many engagements, then still ships as a pull request through your own review. What costs your engineer half a day costs us half an hour, so the small wins finally get captured. One piece of that tooling, our EBS Optimizer, is available on its own for teams who just want their EBS volumes right-sized.
AWS cost optimization results
Anonymized by industry and spend band. Every number measured against the bill before the change.
FinTech scale-up, US
$1.1M+/yr
delivered cost avoidance
~$3M/year AWS under an EDP. In the first two weeks we shipped ~$378k/year of savings, enough to cover our entire fee within a few months. Then IO1 to GP3, right-configured Aurora, RDS rightsizing with RI coverage on top, ElastiCache rightsizing and Valkey, and more.
E-commerce SaaS, US
~30%
off the bill, ~$168k/yr
A bill growing with the business, from $30k to $50k/month. Cut to $36k/month in 3-4 months across RDS, compute, ElastiCache, S3 and EBS.
Every engagement is under NDA, so client names and identifying details are anonymized; references are available under NDA. The savings figures shown were measured against the bill before the change and already delivered. More detail on the case studies page.
