Cloud & APIs

How modern software is built and connected. The foundation under every app and AI system.

APIsRESTGraphQLCloudAWSAPI Management

Why this track exists

Almost everything online is held together by APIs running in the cloud — and yet most explanations assume you already know how it all fits. This track starts from zero and builds the complete picture: what an API is, the different styles, how to design good ones, where they run, and how the pieces connect into a real, scalable system.

It's the foundation under every web app, mobile app, and AI product. Understand this, and the rest of software stops being a fog of buzzwords.

The journey, in order

  1. API Fundamentals — what an API is and how one is built, from scratch
  2. The Types of APIs — REST, GraphQL, gRPC, SOAP, WebSockets, and when to use each
  3. Designing Good APIs — naming, errors, versioning, security, and docs (with the standards)
  4. Cloud Foundations — where your API runs: IaaS/PaaS/SaaS, serverless, AWS/Azure/GCP
  5. Modern Architecture & API Management — how it all connects, and the gateway every serious API needs

Who this is for

  • Beginners and starters who want to understand how modern software is built
  • Builders and founders who need APIs and cloud to ship a real product
  • AI engineers making their systems production-grade and connected

What this unlocks

  • Applied AI — building agents and LLM systems that need robust APIs and cloud infrastructure to reach the world

Courses in this track

1

API Fundamentals: What an API Is & How One Is Built

Available

Start here, even if you've never built software. What an API actually is, how two programs talk through one, and the simple parts every API is made of — explained with everyday analogies and real examples.

The Types of APIs: REST, GraphQL, gRPC, SOAP & WebSockets

Available

There isn't one kind of API — there are several styles, each good at a different job. A plain-English tour of REST, GraphQL, gRPC, SOAP, and WebSockets: what each is, when to use it, and the standard behind it.

Designing Good APIs: Principles & Best Practices

Available

The difference between an API people love and one they curse: naming, versioning, errors, security, and documentation. Practical principles — with the standards to follow — that keep an API clean and usable for years.

Cloud Foundations: Where Your API Actually Runs

Available

Your API has to live somewhere. A beginner's map of cloud computing — renting vs. owning, the IaaS/PaaS/SaaS layers, serverless, and how AWS, Azure, and GCP fit — so you can choose where to build without drowning in jargon.

Modern Architecture & API Management: Putting It Together

Available

How the pieces connect into a real system you could build — the journey of a request, monolith vs. microservices, and the API gateway every serious API needs. The capstone that turns the whole track into one clear picture.
