Welcome to this demo on the OCI Compute Service. Here in this demo, I'm logged in as an ociadmin. Remember this is the administrator for this account. In practice, administrator will set up compartments and give right policies for users to spin up compute instance here. The compute users, in this case, just to keep things simple, log in as ociadmin who has full access to a particular compartment called sandbox. I'm going to spin up compute instance inside that sandbox. To get started, I'll click on "Create a VM instance" here. As I do that, you would see that it's picking up a name for my instance. You can see here, it's picked up my current date. It's asking where to create this instance. It's picked up the compartment that I have the access the sandbox compartment. It put it in the right availability domain. This particular region, US West San Jose has only one AD, so it shows that. Then it shows image and shape. Remember image is your operating system that you put on your instance and maybe support various operating systems. We're going to send OS Oracle Linux, Windows, I'm happy with Oracle Linux. I could create my own image here, custom image. Partners could publish their image. There are lots of other image options which are available. I'm happy with Oracle Linux. Right here you can see that in change shape when I do that, I get an option of virtual machine and bare-metal instances. These bare-metal instances are physical servers which get allocated to me without any hypervisor or anything is the actual machines. I could spin those up, or I could spin up virtual machines. Down below here, you can see the processor choices. I get AMD, Intel, Arm-based processor. In this particular example looks like a particular VM got chosen for me. I'm happy with that. It's always free means even once my free $300 is exhausted, I could keep using this particular instance. I'm happy with this. I'll select the shape. Then down here, it's giving me a virtual Cloud network. Now, in this particular account, we haven't gone through VCN demos. I don't have a virtual Cloud network, so it's creating one for me. More importantly, it's creating a subnet because the compute instances need a subnet in order to be instantiated. We looked into this as part of our theory listen. It's creating one for me, virtual sub network. It's also assigning a public IP address, IPv4 address. If I wanted, I could keep it private. If I was running a database and I would not assign a public IPv4 address here. Down below, it's asking me options for SSH keys. In one of the previous lessons, we generated using SSH key pair, public key and private key. Let me just log in, go to my Cloud shell and bring up these keys. You can see here I have the public and the private keys here. Let me just pull up my public key and copy here the content of my public key. I will paste the public keys here. Using the public and private keys, I'll be able to SSH into this Linux instance. There are options around boot volume. We will look into these as part of the storage demos. Down below, we have options on management, availability, etc. More advanced topics. We're not going to touch on these right now, but we did talk about live migration and in this case, I'm saying that I'm okay with Oracle choosing the best migration option for me. If I was not, I could opt in or opt out for in case my hardware underlying host has an issue. In this case Oracle is going to do live migration. If I was not okay with that, I have couple of options here. These reports selected, I will click on "Create". Within a few seconds, you would see my compute instance will be instantiated. I should be able to SSH into the machine here. As it is getting instantiated, let me just quickly go through some of the quick ones here. Right here, as you can see, it's picking up a fault domain. Every availability domain comes with three fault domains. I pick one randomly. I had an option to provide it. All the four domains are similar, some will pivot this second fault domain, it give me a public IP address here, there's a username. You can see some of the networking details here, like network interface card and some instance details. Again, these are more advanced topics. We are not going to cover these in the foundations course. Now, I have the IP address here, so let me just copy here this IP address and SSH into this machine. My username is opc. As you can see here, I would provide the public IP address. I should also give my private key here. Since I'm in the same directory, I don't need to specify a path. As you can see here, I'm able to SSH into the machine. If I am inside my compute instance here, and if I want to ping an external website like google.com, I could do it from here and you can see that I'm able to ping from inside the instance, I'm able to get out. This is a quick demo of the Compute Service. As you can see here, it has lot of functionality. We will cover some of these in our storage demos and also in networking demos. But for now hopefully this gives you a good overview of how easy it is to get started with the Compute Service. I hope you found this demo useful. Thanks for watching.
