What is AWS, and why is it so popular?
Amazon Web Services (AWS) is the world's largest public cloud platform, offering over 240 services across compute, storage, databases, networking, AI, and security on a pay-as-you-go model.
Breadth of services — from EC2 (virtual servers) and S3 (object storage) to managed AI (Bedrock, SageMaker) and fully serverless platforms (Lambda, Fargate).
Global reach — 33+ Regions and 100+ Availability Zones in 2026, plus 600+ CloudFront edge locations, enabling low-latency global apps.
Pay-as-you-go pricing — no upfront capex, with discounts via Reserved Instances, Savings Plans, and Spot for elastic workloads.
Mature security & compliance — SOC 2, HIPAA, FedRAMP, PCI-DSS out of the box via the Shared Responsibility Model.
First-mover ecosystem — launched 2006; deepest set of tooling, integrations, and a marketplace of partner solutions.
Why popular: AWS combines scale, breadth, and reliability that lets startups and Fortune 500s ship faster without managing data centers.
Lead with breadth + scale + pay-as-you-go. Drop one number — 33+ Regions or 240+ services — to sound current.
Mention the Shared Responsibility Model and you separate yourself from juniors.
