    Serverless Architecture

    Serverless is excellent for spiky, event-driven and glue workloads, and a poor fit for steady high-throughput services where the per-request price never stops. The design work is knowing which of yours is which.

    Start with the audit

    No sales layer, no juniors. You meet the engineer before anything begins.

    // What is included

    What you get

    • Functions and event flows designed around real invocation patterns
    • Cold start, timeout and concurrency limits accounted for before launch
    • Runtime versions tracked against end-of-support dates
    • A cost model that holds at ten times your current volume

    // How it runs

    The sequence

    1. 01

      Qualify

      Which workloads suit serverless and which will cost more there.

    2. 02

      Build

      Functions, events and permissions defined in code.

    3. 03

      Watch

      Concurrency, errors and spend instrumented from day one.

    Where this has been done before

    Client names under NDA. The numbers are not.

    SOC 2-ready security hardening (NDA)

    • IAM rewritten to least privilege with credential rotation
    • Secrets moved to Secrets Manager with Lambda rotation
    • WAF and rate limiting in front of public endpoints

    Controls in place and documented for the SOC 2 audit

    Self-hosted infrastructure retired onto managed services (NDA)

    • Self-managed Kubernetes to ECS and Fargate
    • Configuration store to Parameter Store and Secrets Manager
    • Artifact repository to ECR and CodeArtifact

    Four self-maintained components retired
