Very nice explanation, If possible, please share. A question which useful to clear the AWS exam or interview.Thank you.

[@8xvortex32]

Awesome Video

[@a.ashkir9608]

Awesome! Thank you for putting out this video

[@mielushe2lheureux939]

Nice video, very clear. But, tell me: is it a good practice to store the ssh key inside the public server, I mean inside the webtier ec2 instance, as you did. If not what should be the good practice? Thank you again to share this precious knowledge with us. Cheers!

[@devopstutorial]

Yes, another Good practice is to have keypair rotation

[@smartpromise3430]

It's bad practice to store ssh key inside public or private server please don't do that. Imagine someone having access to that server, they can easily access the key which can have rippling effect on other applications tied to this key. SSH Key should be attributed to an individual not to a shared account or server.

AWS does not allow you to open public access. Is this something that prevents connection to MySQL DB? Also I want to use Retool with AWS and it doesn't seem to connect. CHope you can help.

[@devopstutorial]

Tell me ur setup , from where u r trying to connect to mysql ? Have you open port in security group ? Go to mysql and check for security grop access

1 doubt Why we need http protocol enabled in inbound rule of our application tier instances??

[@devopstutorial]

If port is not open then server will not communicate

Hi I copied your instructions click by click but my public ip4 is not working for the web tier. I also double checked the code for User Data and it’s correct
