AWS services

An EC2 instance is a virtual server in the cloud.. An EC2 instance is a resizable virtual machine that runs on Amazon’s infrastructure, providing compute capacity that you can configure with an operating system, storage, and networking.

AWS Route 53 provides DNS resolution.. Route 53 is AWS’s managed DNS service that translates domain names to IP addresses, enabling both public and private name resolution.

Amazon S3 provides a highly available and durable storage solution for objects such as files, images, and videos, making it ideal for backups, archives, and static content. A diagram for this topic isn't available yet — the worked example below walks the same reasoning step by step.

• !A common confusion is between Amazon S3 and Amazon EBS, as both are storage services, but they serve different purposes and have different use cases. Amazon EBS is used for block-level storage attached to EC2 instances, whereas S3 is used for object storage.
• !Many people confuse Amazon VPC with Amazon S3, mistakenly believing that S3 provides network isolation due to its secure data storage capabilities. However, S3 is primarily an object storage service, not a networking service.
• !Managed databases (like RDS) and serverless functions (like Lambda) do not provide the same level of control and configuration as EC2 instances.
• !CloudFront, Direct Connect, and API Gateway are often misidentified as DNS resolvers, when in fact they serve different purposes.
• !Learners sometimes mistake CloudWatch for a storage or version‑control service, confusing it with S3 or CodeCommit.
