At first system administrator used to do upgrades, secure patches and installation on 100s of servers using shell script that had to loop over all 100s of servers. With cloud( micro service architecture) no. of servers increased and the compute/resources had decreased. Earlier we had to take care of distribution of OS(alpine, ubuntu), so the script might not work. To solve this configuration management came into picture. Puppet, chef and Ansible . Why Ansible over others? Ansible is much a push mechanism model. Write Ansible script at one instance and update all the worker nodes. Ansible is agentless, just put DNS or ip adress of servers in inventory file and have ssh password-less authentication configured, along with python3 installed by default in Linux distros. 2. Ansible also has feature of dynamic inventory. If you are creating 100s of servers in AWS cloud, Ansible will automatically detect new server. 3. Support both Windows, AIX and Linux all distros 4. Ansible is pretty simple, uses simple yaml manifest.

In AWS while creating EC2 instances - we can give some configurations right? So using ECS which has cluster of EC2 instances or something, can't we do the configurations?? Should Ansible be used? Also in Puppet when you are giving multiple slaves - so if 1000 machines are added. you go and add all the 1000 again in the master file?

excellent work but is some one please help to get the command which to used over lab setup

Does Ansible support all cloud providers like AWS,azure,gcp.. Ans. For Ansible it doesn't matter what your cloud provider is. You only need public ip adress, is ssh access allowed publically to your machine(laptop).
