Easy Installation

There are many toolkits that were available before the AWS CLI was introduced. There are so many complex steps involved when one has to install these toolkits like AWS API. There was a need to put up with the multiple environment variables, but now with this new tool, this process has become very much easier. When the developer needs to install the AWS CLI, they can do it very quickly as it is very simple and standardized to use. The installation process has become very much smoother with this new tool.

Time-saving

Even though the AWS management services are very user-friendly, there are many times, it becomes hard to use this tool. We can understand with an example. If you need to search for a big file in the AWS Management services, then you have to log in to your account and look for the right bucket and the right file. But when you are using the AWS CLI, you just have to write that in a line that is the right command, and the task that was taking so much time will be completed within a matter of seconds. This tool is very fast and easy to use as compared to other AWS services.

Process Automation

If we look at the biggest benefit that the team is going to have with the AWS CLI is the ability to automate the whole process while using the AWS services using scripts. Using this, the developers can control and manage the AWS services and this can free the developers from logging in to the AWS Management Console. So, if you are looking to automate the given cloud infrastructure then going for shell scripting can be the best way. And with AWS CLI, you will have an option to do so. This task of automation can be very beneficial for the team when they are going through a critical time in the project.

Supports all Amazon Web Services

Before this tool was not there, there was a need for a dedicated CLI tool when you just want to use the EC2 service from Amazon. It was good to use but one of the major drawbacks was that it can be used for other amazon web services and this is why it was becoming obsolete. This gave birth to the AWS CLI where you are able to control all the AWS services with just one tool and this saves time and energy for all the people working on the project.

There are indeed so many benefits to this tool as this is becoming one of the major choices for developers all over the world.

Secure your credentials
