Week 07 — Production APIs | SoftBricks Academy

What You'll Learn

Wrap your agent in a real API. Containerize it. Deploy it. You'll build a FastAPI service with authentication, rate limiting, and proper error handling, then containerize with Docker and deploy to AWS/GCP/Azure.

Session Schedule

Day	Time	Focus
Saturday	8:00 - 11:00 PM WAT	FastAPI & Docker
Sunday	8:00 - 11:00 PM WAT	Cloud Deployment & CI/CD

Pre-Requisites

Weeks 01-06 completed
Docker Desktop installed
AWS/GCP account (free tier)
Basic Git knowledge

Topics Covered

FastAPI with Async Endpoints

async/await, dependency injection, middleware, streaming responses. Build APIs that handle concurrent requests without breaking a sweat.

FastAPI Async Middleware

LangServe for Agent Deployment

Wrapping LangChain in LangServe, playground UI, input/output schemas. Deploy your agent with a built-in testing interface.

LangServe Playground Schemas

Docker & docker-compose

Dockerfile best practices, multi-stage builds, compose for multi-service. Package your entire stack into reproducible containers.

Docker Compose Multi-stage

AWS / GCP / Azure Deployment

ECS/Cloud Run/Container Apps, load balancing, auto-scaling. Get your containerized agent running in the cloud with production-grade infrastructure.

AWS GCP Azure

Environment Management & Secrets

.env files, secrets managers, 12-factor app patterns. Keep your API keys safe and your deployments consistent across environments.

Secrets .env 12-Factor

Weekly Build: Production AI API

Build and deploy a complete FastAPI service wrapping your agent, with auth, rate limiting, Docker, and cloud deployment.

Code Repository

Clone the bootcamp repo and switch to the week-07 branch:

git clone https://github.com/softbricks-academy/agentic-ai-bootcamp.git
cd agentic-ai-bootcamp
git checkout week-07

Session Recording

Recording will be available within 24 hours after the live session. Check the WhatsApp group for the link.

Homework

Due before Week 8 live session.

Deploy your API to the cloud — push your Docker container to a cloud provider and share the live URL
Add API key authentication — implement middleware that validates keys against a database
Implement rate limiting — token bucket algorithm with configurable limits per API key
Write a Dockerfile with multi-stage build — optimize image size below 500MB
