Function as a Service (FaaS): Core Building Block of Serverless TechnologyWhat is FaaS?

• Simplest unit of work for building applications, microservices, or event-driven protocols
• Basic workflow: Input → Logic → Output

Characteristics of FaaS

• Simple and easily understandable
• Highly scalable
• Quick response time

Popular FaaS Framework: AWS Lambda

• Can be attached to various services:
  • S3 notifications (e.g., file uploads)
  • SQS (Simple Queue Service) messages
• Enables building infinitely scalable services with small response times

Best Languages for Serverless/FaaS

1. Rust
2. Go

Advantages of Modern Compiled Languages for FaaS

• Speed
• Safety
• Optimal deployment characteristics
• Millisecond response and invocation times
• Low energy usage

Key Considerations for FaaS Development

• Focus on maintenance over ease of building
• Optimize for low costs (financial and energy)
• Consider total cost of service over time

Takeaway

When developing Function as a Service applications, prioritize long-term efficiency, maintenance, and cost-effectiveness over initial development ease. Choose languages and practices that support these goals in a serverless environment.
