Cloudwalker Solutions
Stratum gives engineering teams complete observability across serverless workloads — errors, performance, and cost — in a single portal that spans every AWS account and region.
When you run hundreds of Lambda functions across multiple AWS accounts and regions, understanding what's failing — and why, and what it's costing — becomes genuinely hard. CloudWatch helps, but it doesn't aggregate. It doesn't alert owners. It doesn't track spend per function.
Stratum is Cloudwalker's answer to that gap. It continuously monitors every Lambda in your organisation, surfaces errors in real time, notifies the right people automatically, and gives you a daily operational digest — all from a single portal your entire team can use.
Every Lambda error across all accounts and regions is captured, deduplicated, and stored within seconds. Smart alert thresholds notify you at key escalation points — 1st error, 10, 50, 100, 500, and 1,000 — so you catch problems early without being spammed on every occurrence. Alerts go directly to the function maintainer and team.
A searchable, filterable registry of every Lambda in your organisation — runtime, maintainer, region, last modified date, log group presence, and monitoring status. Updated twice daily. Filter by account, owner, or region in seconds.
Duration, invocation count, error rate, and concurrency pulled directly from CloudWatch via standard APIs. Displayed in a frontend-friendly format without requiring engineers to navigate the AWS console or build custom dashboards.
Suppress known, intentional exceptions (Step Function flows, expected business logic errors) with per-function ignore rules. Toggle monitoring on or off for any function at any time directly from the portal — without redeployment.
Every morning at 09:00 CET, Stratum publishes a structured error digest to Confluence and posts a Slack notification with a direct link. Your team starts the day knowing exactly what happened overnight — before anyone needs to ask.
Per-function Lambda compute cost and CloudWatch Logs spend — both storage and ingestion — tracked across all accounts with 6-month trend charts. Configurable thresholds trigger alerts when costs spike unexpectedly or grow beyond defined limits.
Step 1 — Collect
Stratum continuously monitors Lambda error events from every account and region. Everything is handled automatically — you don't configure anything per function.
Step 2 — Process
Each error event is enriched with maintainer tags and function metadata, deduplicated against recent events, and checked against spike thresholds. When thresholds are crossed, alerts fire within seconds — directly to the function owner.
Step 3 — Surface
All data lands in a single portal — filterable by account, region, owner, or date. Every morning a daily digest is posted automatically. Cost data is collected three times daily and presented with trend charts so you can spot runaway spend early.
Most AWS cost tools show spend at the account level. Stratum goes deeper — tracking compute cost and CloudWatch Logs spend (storage and ingestion) down to the individual Lambda function, across all accounts and regions.
Built on AWS — fully managed within your own infrastructure
Stratum gives your team the visibility to triage faster, reduce noise, and keep Lambda costs under control — across every account you run.
