What is Amazon Machine Image (AMI)
An Amazon Machine Image (AMI) provides the data needed to launch an instance. The instance is a virtual server in the AWS cloud. AMI is a packaged environment with all the necessary parts to set up and boot an EC2 instance correctly. You can define an Amazon Machine Images (AMI) when you launch an instance.

What is Amazon CloudWatch Logs?
Amazon Web Services provides secure, high availability, and economical cloud computing services. Though, we should always prepare for the possible breakdown of AWS service. Therefore, we need an alert option present in our system. There is an AWS tool present in our system for monitoring our Cloud-based applications. CloudWatch is the name, and the work suits its name. Cloudwatch is a valuable monitoring service tool for your application that you run on AWS. Moreover, CloudWatch is free to use with the option to pay for more detailed control.
Benefits of Amazon CloudWatch
