Summary

This chapter was all about networking. We started by introducing computer networking and all the various components of computer networking. Then, we drilled down to looking at networking from the AWS standpoint and the different AWS services and the different areas of networking specialty that they cover.

The next stage was then to take some of the services and see how networking works for each of them. We started with Amazon VPC and understood the value of flow logs, and then we created a flow log to demonstrate how we can use it to collect logs of network activities in our VPC and subnets within the VPC. We explained the different information contained within the log and how to interpret the meaning of the logs generated by the VPC flow logs.

We then moved on to load balancers in AWS and looked at the graphs and metrics of a load balancer and what some of the metrics mean. We talked about how to configure alarms for the critical graph metric.

Then we moved on to...
