Summary
In this chapter, we have covered the most important service, Amazon EC2, which helps us to run our application on the server. Also, we covered how we can balance the load between multiple EC2 instances and auto scale the server based on the CPU utilization. We can choose any metrics to auto scale our EC2 instances. These Auto Scaling groups also help us to handle fault tolerance of EC2 instances and scale up and down accordingly. In the next chapter, we will be learning about the Simple Storage Service (S3), which is used to store any type of files and can be accessed over HTTP.
