One-click AWS Deployment

Switch from Copilot to Autopilot. Cloud-9 assumes a least-privilege cross-account IAM role — scoped to ASG updates only, zero billing or IAM write access — and deploys an optimised mixed spot/on-demand policy directly to your Auto Scaling Groups across all 18 supported regions. Revert anytime with one click, and every action lands in an append-only deployment history. Prefer your pipeline in control? Every config also ships as a ready-to-open pull request — your repo stays the single source of truth.

Find Cheapest Spot

Real-time scan across all regions and AZs to find the absolute price floor for your specs.

FREE

Value Score

Weighted index of price, stability, and interruption risk across hardware generations.

PRO

Capacity & Price Forecast

Combines AWS Spot Advisor interruption-rate data with a next-day price-trend model to flag pools drifting toward tighter capacity — the real spot risk, not a stock-ticker price guess.

PRO

Commitment Advisor

Shaved Ice algorithm sizes your EC2, Fargate, and Lambda Savings Plan commitments to minimise total cost across all compute types.

PRO

Auto-Switching Config

Generates production-ready Terraform for mixed spot/on-demand ASGs — with workload eligibility gating, FIS interruption drills, and a revert-safe on-demand floor. Ships as a ready-to-open pull request: savings estimate, eligibility evidence, and revert path in the PR description, so the change flows through your CI/CD with a human in the loop.

Karpenter NodePool

Generates a scored, interruption-weighted NodePool + EC2NodeClass YAML for Karpenter v1 — pre-tuned for spot-to-spot consolidation with ≥15 instance types.

ZERO-DRIFT GITOPS

Ships as a pull request, not a black box

Every generated config — Terraform, Karpenter YAML — comes with a ready-to-open PR: title, description with the savings estimate and eligibility evidence, and the script to open it. Your repo stays the single source of truth; the change flows through your own CI/CD with a human in the loop, not around it.

The 'Shaved Ice'
protocol.

Peer-reviewed at ICPE '25, our algorithm treats cloud capacity as a high-frequency liquid market — then executes on the insight, not just reports it.

01
TELEMETRY INGESTION

567K+ price points ingested from the AWS Spot feed across 18 regions and all availability zones.

02
RISK FACTORIZATION

Historical interruption rates are mapped against real-time fleet demand signals to produce a composite score.

03
FLEET EXECUTION

Your choice of control: Copilot generates Terraform for review, the PR export pushes it through your own pipeline — repo stays the source of truth — or Autopilot deploys directly via a scoped cross-account role with a full audit trail.
