AWS Terminal, putty and mobaxterm

Hi, the 3 of them are ssh terminals that you can use to connect to EC2 instances.

My personal preference goes to EC2 Instance Connect: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-connect-methods.html

1. It doesn't require install of any software on the client machine
2. It's purely web based: you can do it from your laptop, your tablet, your phone, your TV, etc...
3. the connection to EC2 instance is pre-baked: you don't have to manage the ssh private key locally (lose it, have it leaked, etc...)

The fat ssh client have probably one avantage: you can have pre-recorded key sequences to replay set of commands that you use often

Also such a fat client is required if you need / want to run shell scripts from your laptop on the EC2 instance.

Personally, I have 1 fat client that I use for my automation use cases (advanced shell scripts) otherwise for quick connections (when I debug something unexpected) I use EC2 Instance Connect most of time

Best,

Didier
