Highway's product was scaling fast. The AWS estate under it was still run by hand. Streaver made it declarative — and took six figures off the annual bill inside the first month.
A short look at the carrier-identity platform our embedded team keeps declarative, observable, and cheap to run.
Highway builds the carrier identity layer for freight — the system brokers and shippers rely on to know who they're actually doing business with. It's infrastructure for a fast-moving industry, and it has to behave like it.
By the time Streaver came in, Highway was scaling hard: tables taking tens of millions of writes a day, some of the largest RDS instances on AWS, and a platform built for well past two million loads. The product was working. The infrastructure under it was still being run by hand.
Highway didn't have a reliability problem so much as a manageability one. The estate had grown faster than the discipline around it — and the gaps showed up where they hurt most: in releases and on the bill.
ECS services, scaling rules, and capacity were managed manually — with no single source of truth for what was actually deployed, or why.
InfrastructureImage tags, tagging conventions, and sidecars had drifted between services and environments — small inconsistencies that quietly accumulated risk.
DriftInconsistent logging, tagging, and sidecar setup had become release blockers. The infrastructure itself was slowing the team down.
DeliveryCPU and memory were provisioned from experience and caution, not production signal — so the estate was over-provisioned in places and fragile in others.
CapacityThis was the first time Highway had trusted an outside engineering partner with its infrastructure. The engagement had to earn that on day one — and prove, fast, that it was a trusted extension of the team rather than external help.
On day one — January 2 — the team spotted the EC2 → Savings Plans opportunity that became the first chunk of savings. Delivery-first, before any roadmap.
As the months went on, Highway's leadership pulled Streaver deeper — relying on the team's Terraform and AWS judgment rather than treating it as staff augmentation.
Calls were made with the business in mind: what to standardize, what to leave alone, and what to flag for discussion rather than silently change.
The estate didn't need a rebuild. It needed a source of truth — so every change could be reviewed, traced, and justified with data.
Every service, secret, and scaling rule — declared, reviewed, and promoted through CI/CD.
Streaver embedded a platform team and worked in two directions at once: make the estate declarative, and make its behavior legible. Five workstreams carried the engagement.
The Monitor and Sidekiq services moved to Terraform — the first real source of truth for what's deployed and how to promote it. CI/CD gained safer plan / promote / apply flows, deliberate task-definition handling, and no more invisible unapplied changes.
A base secret per environment with optional per-service extension: common values live in one place, exceptions are explicit and controlled, every change is auditable, and duplication drops.
CPU and RAM were re-allocated from real production metrics — CPU, memory, queue pressure, Sidekiq latency, task counts — each change carrying a confidence level and rolled out in batches: high-confidence and low-risk first, with conservative thresholds for critical services.
Puma backlog metrics, CloudWatch and Grafana, and New Relic / Grafana Alloy / Beyla sidecars surface real service pressure — and feed autoscaling, so the platform responds to load instead of to guesses.
Drift from incident-time manual fixes is preserved, not overwritten. Capacity providers are classified by cost and resilience. And the Sidekiq recombination question was handled as analysis — isolation, criticality, ownership, autoscaling — not a change shipped for its own sake.
Six months in, the estate is cheaper to run, safer to change, and able to justify every technical decision with data. Figures with a TBD badge are awaiting Highway's sign-off before we quote them publicly.
Savings Plans on database and compute, plus right-sized capacity — the first cut spotted in the very first meeting.
From kickoff on January 2 to the first savings live on January 29.
ECS under Terraform as the source of truth; drift eliminated as a release blocker.
Dev, stage, and prod brought into alignment so changes promote predictably.
Reallocations driven by production metrics, each with a confidence level and a staged rollout.
The platform now runs declaratively at Highway's current scale, built toward 2M+ loads.
Scale-ups running a serious AWS estate by hand — where infrastructure inconsistency has started to block releases, and capacity is still a matter of intuition.

Infrastructure as code and the CI/CD plan / promote / apply flows.

Evidence-based capacity, the secrets model, and observability.

AWS cost optimization, RDS, and autoscaling signals.
Streaver embeds platform teams into scale-ups running serious AWS estates by hand — turning drift and intuition into a declarative, evidence-governed platform that's cheaper to run and safer to change.
