Purpose

This skill helps design and implement cloud architectures focused on serverless technologies (e.g., AWS Lambda, Cloudflare Workers), edge computing, CDNs, multi-region setups for high availability (HA), and Infrastructure as Code (IaC) using Terraform. It ensures scalable, cost-effective solutions by guiding precise configuration and deployment.

When to Use

Use this skill for applications needing low-latency edge delivery, serverless backends to reduce costs, multi-region redundancy for HA, or IaC automation. Examples include building global APIs, migrating to serverless, or optimizing CDN for media delivery. Avoid for simple monolithic apps or on-prem setups.

Key Capabilities

• Deploy serverless functions: Create AWS Lambda or Cloudflare Workers for event-driven processing.
• Edge and CDN integration: Configure Cloudflare for edge caching and routing to reduce latency.
• Multi-region HA patterns: Set up auto-failover with AWS Route 53 or Cloudflare load balancers.
• IaC with Terraform: Define and provision cloud resources declaratively for reproducibility.
• Cost optimization: Analyze patterns like using Lambda's reserved concurrency or Terraform's cost modules.

Usage Patterns

1. Serverless API Deployment: Use Terraform to define a Lambda function and API Gateway, then deploy for quick scaling. Ensure multi-region setup by adding Route 53 for failover.
2. Edge-Computing CDN Setup: Integrate Cloudflare Workers with a CDN to cache assets and handle requests at the edge, reducing origin server load. Combine with Terraform for automated provisioning across regions.
