Assuming Roles

Dive in to see what it means to "assume a role".

We see how the sts service is used, and what exactly a trust policy is doing for us.

We manually assume a role (with the aws command), and see how we can use the assumed role to perform permitted API calls.

Finally we see how the aws CLI tool assumes a role for us with some configuration! The SDK's do the same thing as well, so we get a real look at how we can use assumed roles.
