Horizontal and Vertical scaling (Explained with AWS example)

Great work...

You took About 20 Minutes to explain this. However the same can be explained in about 2 Minutes. Please DRY. It would be better if you can practically show this.

nice explain.......

Need a link to Load Balancer as well as how it works during session management. e.g.: If there is an active session between server and client, then how load balancer handle that scenario.

OK

Nicely Explained, But i am having one doubt is it possible to do vertical autoscalling automatically? like if cpu utilization goes 80% above then need to increase the instance type from t2.medium to t2.large like that

very good explanation...

If we use ec2 service we use horizontal scaling, and if use rds instances we use vertical scaling?
