Key Concepts

  1. What is FaaS?
  • FaaS is a cloud computing model that executes small units of code in response to events.
  • It abstracts server management, focusing solely on application logic.
  1. Features of FaaS
  • Event-Driven: Executes code in response to triggers (e.g., HTTP requests, database changes).
  • Automatic Scaling: Dynamically scales based on demand.
  • Pay-as-You-Go: Charges only for the time the code runs.
  1. Popular FaaS Platforms
  • AWS Lambda: Offers tight integration with AWS services.
  • Google Cloud Functions: Supports multiple languages and event-driven triggers.
  • Azure Functions: Seamlessly integrates with Microsoft Azure services.
  1. Benefits of FaaS
  • Reduced Operational Overhead: No server provisioning or management required.
  • Cost Efficiency: Ideal for workloads with variable demand.
  • Faster Development: Focus on code logic instead of infrastructure.
  1. Common Use Cases
  • Data Processing: Process IoT data streams, ETL tasks, or real-time logs.
  • Backend Services: Handle REST API requests or event-driven tasks.
  • Scheduled Jobs: Perform periodic tasks like backups or report generation.
  • Third-Party API Integration: Connect with external services via API calls.
