The AWS Console lets you create and manage resources in a very easy and simplistic format. However, eventually, you’ll find that certain operations can be performed more efficiently using the AWS Command Line Interface. For example, say you have tons of EC2 instances supporting a website and you need to run a report to list the Public IP addresses from each one of these servers. These IP addresses may change over time, so you’ve been asked to run the report daily.
How do you do this? You could, of course, manually log into the console, and copy and paste the IP address for each server. Or, you can do this programmatically using the AWS CLI.
Eventually, you’ll find that scripting out commands and creating bash scripts is more efficient for a lot of workloads in AWS - and provides a safer and less error-prone approach to working with AWS resources.
Whenever you create, edit, or delete a resource in the AWS Console, you’re making an API call to the services. You can make these same API calls using the AWS CLI. The difference is how you interface with the API. Instead of logging into the console, you’ll use a terminal program to access the AWS CLI.
You can use a Linux shell, the built-in MAC terminal, an EC2 instance, or if you’re on a PC, you can use a program like PuTTy.
In summary, the AWS CLI is a powerful tool that provides more flexibility to access and manage AWS resources. That’s it for this one - I’ll see you next time.
