Amazon EC2 provides resizable compute capacity in the cloud, making it easy for developers to run applications on a virtual server. This service offers scalability and control over the computing environment, enabling users to manage and deploy any application.
AWS Lambda
AWS Lambda allows users to run code without provisioning or managing servers. This serverless computing service automatically scales applications in response to incoming requests, making it highly efficient.
2. Storage Services
Amazon S3 (Simple Storage Service)
Amazon S3 provides scalable object storage for data backup, archiving, and analytics. It is designed for durability and offers easy-to-use management features to organize and retrieve data.
Amazon EBS (Elastic Block Store)
Amazon EBS offers persistent block storage for use with Amazon EC2, providing high availability and performance for applications that require constant data access.
3. Database Services
Amazon RDS (Relational Database Service)
Amazon RDS simplifies the setup, operation, and scaling of relational databases in the cloud, offering support for various database engines.
Amazon DynamoDB
DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.
4. Networking Services

Compute: Amazon EC2, AWS Lambda.
Detailed Explanation
AWS offers compute services that allow users to run applications and manage workloads. Two major services under this category are Amazon EC2 and AWS Lambda.
- Amazon EC2 (Elastic Compute Cloud) is a service that provides resizable compute capacity in the cloud. It allows users to rent virtual servers to run their applications without investing in physical hardware.
- AWS Lambda is a serverless computing service that lets users run code in response to events without provisioning or managing servers. It automatically manages the compute resources required by your code, allowing you to focus solely on the function of your application.
Examples & Analogies
Think of Amazon EC2 as renting an office space where you can set up your own furniture and equipment β you manage everything and control how itβs used. On the other hand, AWS Lambda is like hiring a service where you only pay when you need specific tasks done, like scheduling a cleaning service that shows up only when you need it.
