Hands-on tutorials for Claude Code, AI agents, cloud and system design
A look at how Amazon Lambda works. AWS Lambda runs your code on demand without you managing servers, and the architectural feat that makes it economically viable is Firecracker microVMs, a purpose-built VMM that boots a fully-isolated VM in ~125 milliseconds. That single engineering choice is what let AWS offer “pay per 100ms of execution”… Continue reading
A look at how Meta serverless works. Meta’s serverless platform runs internal webhooks and async jobs for Facebook, Instagram, and WhatsApp at a scale that dwarfs every public serverless offering combined. The architectural choice that makes it work is TwSF (Meta’s internal async workflow framework), purpose-built for the call patterns Lambda was never designed for…. Continue reading
Agentic AI transforms how cloud architects build intelligent systems on AWS. Instead of writing rigid procedural code for every workflow, you delegate goals to software agents that perceive context, reason about trade-offs, and act on your behalf. This guide covers the foundations and shows how Amazon Bedrock, AWS Lambda, and AWS Step Functions bring autonomous… Continue reading
Serverless AI runs agentic workloads without provisioning a single EC2 instance. Lambda, Bedrock, AgentCore, and Step Functions compose into elastic, pay-per-use architectures that scale to zero between requests. Serverless AI: What You’ll Learn Serverless AI runs agentic workloads on fully managed, event-driven AWS services instead of provisioned infrastructure: Lambda for orchestration, Bedrock for foundation model… Continue reading
