What is Function-As-a-Service (FaaS)?

Function-as-a-Service lets developers run small pieces of code in the cloud without setting up or managing any servers. Each function runs only when a specific event triggers it, like a file upload or an API call, and the provider handles scaling, patching and infrastructure behind the scenes. Costs get tied directly to the compute time a function uses, cutting waste and speeding up how fast new code reaches production.

Capabilities

  • Event-Driven Execution – Functions run automatically in response to triggers like database changes, HTTP requests, or scheduled jobs.
  • Automatic Scaling – The platform spins up as many instances as needed during traffic spikes, then scales back down when demand goes down.
  • Pay-Per-Use Billing – Costs get tied to actual execution time and requests.
  • Rapid Deployment – Developers can push code straight to production without provisioning hardware or configuring runtime environments.
  • Microservices Support - Functions work well as independent, loosely coupled pieces within larger application architectures.
  • Built-In Fault Isolation – A failure in one function stays contained, so the rest of the application keeps running.

Application Modernization services help clients redesign legacy applications around cloud-native, event-driven patterns like FaaS, cutting infrastructure overhead while boosting agility. Backed by certified engineers and a proven managed operations framework, businesses get application architectures built for speed, cost efficiency and long-term scale.
