- AWS, Azure and Google Cloud all offer similar core services, so the basics transfer between them.
- AWS has the widest market share, Azure fits Microsoft-heavy companies and Google Cloud is strong in data and AI.
- Set budgets and alerts from day one to avoid surprise bills.
The Short Answer
The three big cloud platforms are Amazon Web Services (AWS), Microsoft Azure and Google Cloud. They all rent you computing, storage, databases and networking over the internet, and the core ideas are the same. For a beginner, pick the one most used in the jobs or projects you want, learn the fundamentals and then add another later. Free tiers and credits change often, so confirm current offers on each provider's site.
What the Cloud Gives You
Instead of buying servers, you pay to use them when needed. That means you can host a website, store files, run databases or train an AI model without owning hardware. If you only need a website, ordinary hosting may be enough, as explained in web hosting types explained.
