Function as a Service (FaaS): Core Building Block of Serverless Technology

What 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.

Noah Gift guides you through a year-long journey with 52 Weeks of Cloud, a weekly exploration designed for anyone building, managing, or simply curious about modern cloud infrastructure. Each episode digs into a specific technical topic, moving beyond surface-level explanations to offer practical insights you can apply. You’ll hear detailed discussions on the platforms that power the industry-like AWS, Azure, and Google Cloud-and how to navigate multi-cloud strategies effectively. The conversation regularly delves into the orchestration of these systems with Kubernetes and the specialized world of machine learning operations, or MLOps, including the integration and implications of large language models. This isn't just theory; it's a focused look at the tools and methodologies shaping how software is deployed and scaled today. By committing to this podcast, you're essentially getting a structured, expert-led curriculum that breaks down complex subjects into manageable weekly segments, all aimed at building a comprehensive and practical understanding of the cloud ecosystem.
