Security groups implicitly deny all traffic and only support ‘allow’ rules. NACLs support both ‘allow’ and ‘deny’ rules, which are evaluated in order by rule number.

A policy defines permissions but does not contain the username of the identity it is attached to; the ‘Principal’ element is used in resource-based policies to specify who is granted access.

Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. It is serverless, so there is no infrastructure to manage.

CloudFront is a content delivery network (CDN) that caches content in edge locations around the world, closer to users, to reduce latency.

An Auto Scaling group maintains a collection of EC2 instances, automatically replacing any that fail and adjusting the number of instances based on defined policies.
