Hello. Welcome to OCI. My name is Sergio Castro. Today, we're going to do a lab. We're going to be creating a virtual cloud network. Let's go ahead and get started. These are the topics that we will be seeing today. We're going to be creating a virtual cloud network with the wizard, then we will create a second one, but we will do this one manually so we need to add our own resources. Thirdly, we are going to create a network security group and attach it to a compute instance, vNIC. Let's go ahead and start doing that. Go ahead to your browser and go to cloud.oracle.com. You're going to be landing to this sign-on page, here you enter your Cloud account name or your tenancy, then click "Next", then login with your credentials. This is the landing page. We can immediately go ahead and create our network with the wizard, but because this might change, the menu is the best option. Here you go all the way down to networking, select Virtual Cloud Networks, and make sure that you're in the correct region that you want. In this case, we'll select San Jose, and also make sure that you're in the right compartment. As you can see, I have no virtual cloud network here, so my two options is create a VCN. This is the one that you have to do everything manually, and the first topic is to use the wizard. Let's go ahead and make that selection. The wizard will create all of these resources for us: the virtual cloud network, a public subnet, a private subnet, the Internet gateway that will allow bidirectional communication to the Internet, and NAT gateway, this allows a one-way communication, and a service gateway so you can reach your public-facing OCI resources. It's really easy. Click the "Start" button, give your VCN a name; make sure that you're in the right compartment. These are the default CIDR prefixes. For fun, I'll change them to 254 to make sure that it doesn't overlap with a previously created one, which I don't have but you can leave other parts if you want. Then, in this case, I will be using my DNS host names in the VCN. All you have to do is click "Next" and review that you're okay with all of these being created and hit "Create." Just like that, your VCN is going to be provisioned for you. Right now we're waiting for the private subnet, and it's done. Let's go ahead and view. Here's the private subnet, the catalyst demo. This is the public one. It did create the Internet gateway for us. This is the net gateway right here and the service gateway. Let's go ahead and check the route tables. As you can see, we have two route tables. If we take a look at the routes, this is the default one, it's provided me with a route to the Internet gateway. If I go to my Security List, you'll see that I will also have two security lists: a default one and one for the private subnet. In this case, let's open the one for the private subnet. You will see that by default port 22 is provision, so if you create a compute instance then you can SSH into it, but because this is the private subnet, only from within this source. If we go ahead to the default one, you will see that the source is different, it's the open Internet port 22, and you also have ICMP enabled. This concludes Lab 1. The next lab we will be seeing the manual process of creating a virtual cloud network. Everything that I show you right now, you'll have to act manually. Thank you very much. Bye.
