What is AWS?

AWS stands for Amazon Web Services, it is a platform that provides easy-to-use, cost-effective, and reliable cloud computing solutions.

The various services provided by AWS are:

1. EC2 (Elastic Compute Cloud)

2. Light Sail

3. Elastic Beanstalk

4. EKS(Elastic Kubernetes Service)

5. AWS Lambada

from the following services, EC2 is a service that is widely used.

EC2(Elastic Compute Cloud):

EC2 is one of the oldest services provided by AWS. It is a service that provides a virtual machine to the user. This helps reduce the investment cost required for hardware which makes the process of developing and deploying the application faster and smoother. As the name suggests this service is resizable in nature, it can easily be used from the smallest companies to the biggest companies in the market. It offers an extensive range of instances that provides different resources according to the client’s requirements.

What is an Instance?

An instance is the smallest program/server which consists of its own hard drive, network connection, and operating system. These instances are virtual in nature. The different types of AWS instances help to execute applications on various platforms easier.

When an instance is launched; according to the type of instance it is determined the hardware used. Each type of instance provides a wide range of resources based on the use and requirement of the applications. These type of instances are further divided into classes

The instances can be derived into the following:
