Join Brandon Rich for an in-depth discussion in this video Understand AWS Auto Scaling, part of Amazon Web Services: Deploying and Provisioning.
- [Narrator] Let's take a look at AWS auto scaling,…one of the main ways that AWS allows you…to dynamically change your compute capacity.…When you deploy a web application,…you're taking it out of the cozy confines…of your development environment…and into the real world where it will be exposed…to real world traffic.…As your app's popularity increases, so will its load.…You could just increase the capacity of your single host.…That's called vertical scaling,…and in EC2 it'll require a reboot and some downtime…while you change your instance type.…Or you could introduce another host,…then add a load balancer to distribute the traffic…across those two hosts.…
This is called horizontal scaling,…and it tends to be a more robust, resilient way…of scaling an application…since, unlike with vertical scaling,…you can add capacity without needing to reboot host.…However, horizontal scaling can require…some tedious, manual work.…You must build and provision a new machine,…deploy your application to it,…and add it to the load balancer.…
