Is AWS or cloud necessary to get a devops job of 3.5 yes experience. Please let me know.
Also thank you your doing a fantastic job
If you have 3.5 years experience then After all it is very important to learn cloud infrastructure. Because the basic need of companies nowadays is cloud automation. Terraform and Ansible are not so difficult as compared to other devops tools
Yes.. u must
Devops needs servers and networking to achieve cicd and stuff. Cloud plays a key role in that

1. my application container running in one EC2 server ...and application related database running in anotherv EC2 server .... How can we connect these two container ? Could please explain
U can use docker-compose file
Security group! Simple, don't overthink. If they're both in same VPC, which they should.
Ssh topic is based on docker container?

Can I learn DeVops and find a job
What is the Laptop configuration required for learning and practicing the DeVops course
I cannot comment on your first query. But for laptop configuration, here are some tips - You don't need high end laptop, have a free tier AWS account and use it for free for 12 months. You can access everything from your laptop browser. Before you start using free tier account, make sure you read all schemes related details carefully. Otherwise you will get charged for consuming resources which are not included in free tier.
If you do not want to leverage the cloud services and want to do it locally(on your personal laptop) with help hypervisors like Oracle VirtualBox or VMWare, then you will need high end laptop.
For example: If you want to build CICD pipeline like explained in this video czcams.com/video/WUv-LCRrdjY/video.html which has five VM provisioned in Google Cloud Private, in you laptop, then your laptop should have at-least 16 GB of RAM, 6 cores.
Above are my suggestions, I would suggest to wait for author to reply.
I would suggest - Start learning individual tools first ansible, docker, kubernetes and all others and at last start learning CICD pipeline with Jenkins
can you do video on kubernetes interview questions?
Thanks for watching, I have already uploaded few please checkout the playlists
Bro 1 question :
I want to ssh into all vm machines in all folders and all projects under my org .
After ssh I want to run a "sudo install apache2"

you need to use Ansible script to install the Apache in all machines
You can have list of server in CSV or text loop tho all the server and install software which one you wanted.
