About AWS Glossary

AWS Glossary is a free educational resource that provides clear, accurate definitions of Amazon Web Services — the services, concepts, certifications, and pricing models that power the modern cloud. Our goal is to make cloud terminology accessible to everyone, whether you are preparing for a certification, researching a new service, or ramping up on AWS.

Our Mission

AWS has more than 200 services and the list grows every year. Whether you are configuring your first VPC, comparing ECS and EKS, or studying for the Solutions Architect Associate exam, you deserve clear answers without the sprawl. We break down every term into plain English with real-world examples.

Accuracy & Sources

Articles are grounded in official AWS documentation, the AWS Well-Architected Framework, service quotas, and AWS certification exam guides. We update content regularly to reflect new services, deprecations, and pricing changes.
