In this tablet talk we are going to discuss how the underlying AWS network actually works. This will be an advanced conversation that will describe how traffic moves through the VPC, from the internal IP spaces to the external world, as well as how instance to instance communication takes place. There are a few hidden AWS services that make all the magic happen behind the scenes, and we are going to talk about them in this tablet talk.
