Why AWS?
There are three major cloud providers. Here's why this course starts with AWS.
AWS, Azure, and Google Cloud all do the same fundamental job. This course focuses on AWS for a few concrete reasons.
The largest public cloud by both revenue and adoption.
Datacenters across 30+ geographic regions worldwide.
200+ services, covering nearly every use case you'll run into.
The highest number of cloud job postings ask for AWS specifically.
Most Fortune 500 companies run on AWS, which is exactly why it dominates job postings. The underlying concepts here, regions, IAM, compute, storage, networking, transfer almost directly to Azure and GCP once you know one provider well.
AWS isn't the only cloud provider, it's just the one with the biggest footprint and the most jobs asking for it by name. What you learn here carries over to any other cloud.
