Application delivery without managing server infrastructure

Core Idea: Serverless deployment is an approach to application hosting where developers deploy code without provisioning or managing servers, with the infrastructure automatically handling scaling, high availability, and maintenance.

Key Elements

• Key Features

  • No server provisioning or management
  • Automatic scaling (including scaling to zero)
  • Pay-per-execution pricing model
  • Built-in high availability
  • Event-driven execution patterns
  • No persistent runtime environment
  • Stateless execution model
  • Rapid deployment and iteration

• Technical Specifications

  • Execution time limits (typically seconds to minutes)
  • Memory allocation restrictions
  • Ephemeral file system access
  • Cold start latency considerations
  • Limited CPU burst capacity
  • Restricted execution context
  • Vendor-specific deployment formats (functions, containers)

• Use Cases

  • API backends
  • Microservices
  • Data processing pipelines
  • Webhooks and integrations
  • Scheduled tasks
  • Event-driven automation
  • IoT data ingestion
  • Authentication services

• Implementation Steps

  1. Select appropriate serverless platform for requirements
  2. Structure application for stateless execution
  3. Package code according to platform requirements
  4. Configure event triggers or HTTP endpoints
  5. Set up environment variables and secrets
  6. Deploy with platform-specific tools
  7. Configure monitoring and alerts
  8. Implement CI/CD for automated deployment

• Common Serverless Platforms

  • AWS Lambda
  • Google Cloud Functions
  • Google Cloud Run
  • Azure Functions
  • Vercel
  • Netlify Functions
  • CloudFlare Workers
