AWS

Amazon Web Services (AWS) is the dominant cloud platform. In 2025, the focus is heavily on Generative AI (Bedrock, Q, Trainium chips) and Serverless Data (Aurora Limitless).

When to Use

• Enterprise: The default choice for large-scale, compliant infrastructure.
• AI/ML: Amazon SageMaker and Bedrock provide the deepest toolset for training and inference.
• Serverless: Lambda + DynamoDB + API Gateway is the canonical serverless stack.

Core Concepts

VPC (Virtual Private Cloud)

Your isolated network. Subnets, Route Tables, Internet Gateways. Understanding networking is mandatory.

IAM (Identity and Access Management)

Global service for permissions. "Deny by default". Use Roles for services, not access keys.
