If you’re preparing for AWS certifications or working with cloud services, you’ve probably noticed that some services start with Amazon while others start with AWS. Here’s the simple rule:

✅ Services that start with “Amazon”

These are higher-level, customer-facing or application-level cloud services.

Examples:

• Amazon EC2

• Amazon S3

• Amazon RDS

• Amazon DynamoDB

• Amazon CloudFront

• Amazon VPC

• Amazon SageMaker

• Amazon Lex

• Amazon Polly

✅ Services that start with “AWS”

These are foundational, infrastructure, security, or management services.

Examples:

• AWS IAM

• AWS Lambda

• AWS Glue

• AWS Backup

• AWS WAF

• AWS Shield

• AWS Organizations

• AWS CloudFormation

• AWS CodePipeline

🧠 Easy Way to Remember

• If it feels like a product → it starts with Amazon

• If it feels like infrastructure, security, governance, or deployment → it starts with AWS
