Instance basics

“

(logo humming) - Welcome to this lesson on instance basics. Let's look at some of the instance basics here. So when we say an instance, what we mean is a compute host and it has several dependencies, so let's look at them. So, you have an Oracle Cloud region here. A region is comprised of multiple ADs, and AD is nothing but a data center as you can see here. The first dependency the compute service has or compute host have is on virtual cloud network, so in order to spin up an compute instance, you need a virtual cloud network. As you can see here, you have a network. We divide it into smaller portions called subnets, so you have a subnetwork here, and you need to create these before you can spin up a compute host. Now, you can spin up a compute host. It's a physical construct. Networking is a virtual construct. So, how are they related? Within a compute host, you have a physical network interface card, and you virtualize that card. We virtualize that card, give you this virtual NIC…
