Summary

In this chapter, you have implemented a full end to end solution that provides resiliency and scalability to the web server tier using AMIs Auto Scaling groups and Elastic Load Balancing by provisioning and configuring an application load balancer.

We discussed different types of load balancers available and the benefits and tradeoffs of each one. A mention of some of the most relevant and day to day use attributes available like cross-zone load balancing and connection draining.

With Auto Scaling we created a logical grouping of instances that is designed to provide a minimum capacity at all times and tested by the injection of failure to observe how the system performs auto-healing.
