AWS released AWS CloudShell on 15/DEC/2020. We can operate with shell environment with it.
In your AWS Console after login, you can see the link button of AWS CloudShell.
When you access to AWS CloudShell, you can see this information dialog.
This article is the Memo that I learned about AWS CloudShell.
Cannot get EC2 Metadata
As first impression of console, it seems EC2 instance. So I tried to get Metadata but couldn't.
Preparing your terminal...
Try these commands to get started:
aws help or aws <command> help or aws <command> --cli-auto-prompt
[cloudshell-user@ip-10-0-XX-XXX ~]$
[cloudshell-user@ip-10-0-XX-XXX ~]$ sudo curl http://169.254.169.254/latest/meta-data/
curl: (7) Couldn't connect to server
In official blog, there is a condition. Internal access will be available later.
Network Access - Sessions can make outbound connections to the Internet, but do not allow any type of inbound connections. Sessions cannot currently connect to resources inside of private VPC subnets, but that's also on the near-term roadmap.
About Python and Node.js environment

$ node --version
v12.18.4
$ python3 --version
Python 3.7.9
Initialize timing of the environment
After installing pandas with sudo command, close the console tab and open the console again. The pandas is remained as installed.
$ sudo pip3 install pandas
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

Installing collected packages: numpy, pandas
Successfully installed numpy-1.19.4 pandas-1.1.5
$ pip3 freeze | grep pandas
pandas==1.1.5
After close and open the tab (CloudShell console) pandas is still installed.
$ pip3 freeze | grep pandas
pandas==1.1.5
We need to understand about timing of initializing the CloudShell environment or how we can initialize the environment.
Different IAM user, different environment
It should be. But I could confirm. For different IAM user, different CloudShell environment will be provided.
Preparing your terminal...
Try these commands to get started:
aws help or aws <command> help or aws <command> --cli-auto-prompt
[cloudshell-user@ip-10-1-XXX-XX ~]$
As the information, when I confirmed the user who executed AWS CLI, the user was the IAM user which logged in AWS console.
$ aws sts get-caller-identity
{
"UserId": "ABCDEFGHIJKLMNOPQRSTU",
"Account": "123456789012",
"Arn": "arn:aws:iam::123456789012:user/test"
}
[Conclusion] Convenient environment not depended on your PC environment
With AWS CloudShell, you can avoid the situation when you replace your PC, you need to prepare AWS CLI environment. Currently internal accessing like VPC cannot be operated but it is included near future roadmap. This new service is very convenient for us to operate AWS resources.
