In simple words AWS allows you to do the following things:

  • Running web and application servers in the cloud to host dynamic websites.
  • Securely store all your files on the cloud so you can access them from anywhere.
  • Using managed databases like MySQL, PostgreSQL, Oracle or SQL Server to store information.
  • Deliver static and dynamic files quickly around the world using a Content Delivery Network (CDN).
  • Send bulk email to your customers.


EC2 (Elastic Compute Cloud): These are just the virtual machines in the cloud on which you have the OS level control. You can run whatever you want in them.

LightSail: If you don’t have any prior experience with AWS this is for you. It automatically deploys and manages compute, storage and networking capabilities required to run your applications.

EKS (Elastic Container Service for Kubernetes): Allows you to use Kubernetes on AWS without installing and managing your own Kubernetes control plane. It is a relatively new service.

Lambda: AWS’s serverless technology that allows you to run functions in the cloud. It’s a huge cost saver as you pay only when your functions execute.

Batch: It enables you to easily and efficiently run batch computing workloads of any scale on AWS using Amazon EC2 and EC2 spot fleet.

Elastic Beanstalk: Allows automated deployment and provisioning of resources like a
highly scalable production website.


S3 (Simple Storage Service): Storage service of AWS in which we can store objects like files, folders, images, documents, songs, etc. It cannot be used to install software, games or Operating System.
