It’s not practical to have your own servers nowadays unless there is a compelling reason. Cloud computing vendors offer a lot with their products. Cloud computing can offer lower costs than buying and managing physical servers.
It makes sense to run virtualized servers using AWS’s EC2 platform. EC2 becomes even more powerful when you can autonomously deploy and remove your virtual infrastructure. Let’s now look at how to control EC2 using the command line.
What is EC2?
Amazon’s AWS Services offer EC2 as a cloud computing product. EC2 is a virtual service.
Businesses would traditionally purchase hardware to run different applications. Each physical server could only run one OS at a time, with many different applications within that OS. It became a common practice to run virtualized server hardware on top of physical servers as information technology improved.

Sandboxing operating system and applications from one another
Security – Increased
Lower total cost of ownership
Maintenance costs are reduced

Businesses still need to maintain physical hardware, network infrastructure, and internet connections when using physical hardware. While operational costs can be reduced, they cannot be eliminated.
EC2 takes this one step further. Organizations don’t have to worry about maintaining physical hardware, the network that powers the virtualized environment, and connectivity by moving it to the cloud. Because EC2 works in Amazon’s data centers, there is a lower chance of a downtime issue. EC2 can be cheaper than buying and maintaining physical servers.
What is AWSCLI?
The AWS CLI allows you to interact with Amazon’s AWS resources via various shell environments. The AWS CLI is compatible with Linux, Mac OS, and Windows. Amazon also offers a Docker container that can be used with the AWS CLI.
You might mistakenly believe that the AWS CLI is an AWS utility. This confusion can be common for cloud engineers new to AWS. Command-line utilities are not often referred to as a command line interface. The AWS-CLI in this instance is nothing more than an executable which runs within other shell environments such as PHP, NodeJS or MySQL.
The AWS-CLI is compatible with Windows Command Prompt and Windows PowerShell. It can also be used with Bash, Mac OS Terminal, Bash, Bash, Bash, and other shell environments. Each command is called using the ‘aws command followed by the name of the service (Eg). EC2 and then various flags to indicate what the command should do.

How do I install AWS CLI
You must first install the AWS-CLI before you can use it. Amazon offers AWSCLI packages for Windows (Command Prompt, PowerShell and PowerShell), Linux(Bash, Zsh and tcsh), Mac OS (Terminal) and Linux (Bash. Zsh, and tcsh). Amazon also offers AWS-CLI in a Docker container.
Although the Docker version is portable and easy-to-use, you will need credentials and configuration information to the Docker container that hosts the AWSCLI application in order to link it with your Amazon account. It’s usually just as easy to download the native AWS-CLI version for your computer’s operating system.
The AWS-CLI can also be purchased in V1 and V2 versions. V1 of AWS-CLI is now deprecated. Amazon recommends that you use V2 unless you have a reason to use AWSCLI V1. V1 of AWS-CL
