What Is AWS (Amazon Web Services)? Services and Applications | Simplilearn

AWS stands for Amazon Web Services, it needs no formal introduction, given its immense popularity. The leading cloud provider in the marketplace is Amazon Web Services. It provides over 170 AWS services to the developers so they can access them from anywhere at the time of need.

AWS has customers in over 190 countries worldwide, including 5000 ed-tech institutions and 2000 government organizations. Many companies like ESPN, Adobe, Twitter, Netflix, Facebook, BBC, etc., use AWS services.

For example, Adobe creates and updates software without depending upon the IT teams. It uses its services by offering multi-terabyte operating environments for its clients. By deploying its services with Amazon services, Adobe integrated and operated its software in a simple manner.

Now, before getting started with what is AWS, let us first give you a brief description of what cloud computing is.

What is Cloud Computing?

Cloud computing is the delivery of online services (such as servers, databases, software) to users. With the help of cloud computing, storing data on local machines is not required. It helps you access data from a remote server. Moreover, it is also used to store and access data from anywhere across the world.

What is AWS?

AWS Meaning: The Amazon Web Services (AWS) platform provides more than 200 fully featured services from data centers located all over the world, and is the world’s most comprehensive cloud platform.

Amazon web service is an online platform that provides scalable and cost-effective cloud computing solutions.

AWS is a broadly adopted cloud platform that offers several on-demand operations like compute power, database storage, content delivery, etc., to help corporates scale and grow.

How Does it Work?

That was all about what is AWS. Next, let’s have a look at the history.

How Does AWS Work?

AWS usually works in several different configurations depending on the user’s requirements. However, the user must be able to see the type of configuration used and the particular server map with respect to the AWS service.

Advantages of AWS

  1. AWS provides a user-friendly programming model, architecture, database as well as operating system that has been already known to employers.
  2. AWS is a very cost-effective service. There is no such thing as long-term commitments for anything you would like to purchase.
  3. It offers billing and management for the centralized sector, hybrid computing, and fast installation or removal of your application in any location with few clicks.

  5. AWS offers a total ownership cost at very reasonable rates in comparison to other private cloud servers.

Disadvantages of AWS

  1. AWS has supportive paid packages for intensive or immediate response. Thus, users might need to pay extra money for that.
  2. There might be some cloud computing problems in AWS especially when you move to a cloud Server such as backup protection, downtime, and some limited control.
  3. From region to region, AWS sets some default limitations on resources such as volumes, images, or snapshots.
  4. If there is a sudden change in your hardware system, the application on the cloud might not offer great performance.


Migration services use 3 different sub-services, DMS, SMS, and snowball to transfer the data physically from Datacenter to AWS.

  1. DMS also known as Database Migration Service is used to migrate one database to another.
  2. SMS is a Server Migration Service that helps to migrate on-site servers to AWS within a short period of time.
