1.8 The three major providers, side by side

What this is and why it exists

Job descriptions, syllabi and tutorials each assume one provider's names for the same handful of ideas. This lesson gives you the map: the three major providers, their shapes, and the translation table that lets you read all three while learning one deeply.

The vocabulary

• AWS (Amazon Web Services) — the oldest and broadest of the three, with the largest service catalogue.
• Microsoft Azure — strongest where organisations already live in Microsoft's estate; second by size.
• Google Cloud — smaller than both, with a reputation strongest in data and machine-learning services.
• Hyperscaler — a provider operating at global scale; these three are the ones the word usually means.

The mental model

One idea, three names. Underneath the branding, the providers sell the same conceptual catalogue, because the needs are the same everywhere. The translation table for the core ideas:

Learn one provider deeply — whichever your course, employer or project puts in front of you — and read the other two through this table. The concepts transfer whole; what changes is names, consoles and billing quirks. A person who understands what object storage IS can work in any of the three columns after a day of name-learning; a person who memorised one console cannot.

The smaller providers — regional clouds, Indian data-centre operators, specialist hosts — fit around the edges: closer support, local billing, sometimes local-law comfort. They matter in practice and appear in Indian job markets; the concepts you learn here apply to them unchanged. All three majors run regions in India.

What you should now be able to explain or do

Read a job description naming any provider's services and say what each service is in plain words. Name the typical strength of each of the three. Explain why learning concepts beats memorising one console.
