AWS Auto Scaling using Python Boto3

Auto Scaling Group in AWS configure using Python Boto3  What is Auto Scaling means?  This is key capability or power of Cloud Computing Engineers believe in their skills on scaling abilities.  Amazon EC2 Auto Scaling helps to maintain application availability and lets automatically add or remove EC2 instances using scaling policies that we define.  There are 2 types of scaling policies : Dynamic or predictive. These scaling policies let us add or remove EC2 instances capacity to service established or real-time demand patterns. It contains various steps involved in Auto Scaling process using Python Boto3 we will explore every step that accumulate to form a complete automation solution for a DevOps project. ASG Groups associated with ELB and EC2 instances   Understanding AWS Auto scaling configuration steps Check any running instances Create launch configuration Configure ASG for Auto scaling Verify the configuration Disable Auto Scaling In order to setup A...
