EC2 spot instance in AWS

In this article, we will discuss the EC2 spot instance in AWS.

What is an EC2 spot instance?

Whenever an EC2 instance is allocated to the customer, the AWS always reserves the extra capacity to deal with the surge in demand. This extra capacity is allocated to other clients to run their applications at much cheaper rates.

This extra capacity EC2 instance is called the EC2 spot instance.

Drawback of using the EC2 spot instance

In case there is a surge in demand, the AWS terminates the EC2 spot instance with the short notice.

How to create an EC2 spot instance?

At the time of creating an EC2 instance, you have to tick the "Request Spot Instances" checkbox. Once you tick the checkbox, you can see the different availability zones and their per hour charges.
