In this tutorial, you will learn how to quickly create a VPC and link a tier network on Jotelulu.
A VPC is essentially what we might call a Super CIDR, a network that contains subnets or tier networks, whereby each tier corresponds to a VLAN. These tiers are connected to each other and to the internet through a virtual router.

How to create a VPC and link a tier network on Jotelulu?
Before you begin
To successfully complete this tutorial, you will need:
- To have an account on Jotelulu with a Servers subscription. IF you need more information about how to create a Servers subscription, have a look at the tutorial entitled: How to Deploy a New Server on Jotelulu.
Step 1. Open the Servers subscription page
Step 1. Open the Servers subscription page
Step 2. Open the Networks/IPs section and Create a VPC
On the Servers subscription page, click on Networks/IPs in the left-hand menu (2). Click on the VPC Networks tab (3) and then click on the Create VPC Network button (4).
Step 2. Open the Networks/IPs section and Create a VPC
Step 3. Assign a name to the VPC network
First, you will need to name your new VPC (5) so that it is easily identifiable in the future (in the example, it is named simply “VPC1”). If you do not enter a name, the platform will generate one automatically. Once you have named your VPC, click on Continue (6).
Note: The Super CIDR (shown in orange) will be automatically generated by the platform. This is a network that will be made up of all the subnets or tiers. This Super CIDR can be modified. However, bear in mind that any tiers that are created later on must be contained within the same Super CIDR.
Step 3. Name your VPC network
Step 4. Add and name a tier on the VPC
By creating a tier network, you can then add rules for how to access the network from the outside.
Once your VPC has been created, a message will appear in the VPC Networks section saying “This VPC network does not yet contain a tier” (7). Click on the three dots to the right and click on Add Tier (8) in the drop-down menu.
Step 3. Add the tier to your VPC network
At this point, the platform will ask you for a name for the tier (9). If you do not fill in a name, the platform will generate one automatically. Naming your VPCs and tiers in a systematic way is good practice and will help you to link them and be more efficient in the future.
Note: The range 10.1.0.0/24 that is assigned by the platform by default is contained in the Super CIDR 10.1.0.0/16.
Step 4. Name your tiers and VPCs to identify them more easily later
You will now have successfully created and named a VPC and a tier network. Both will appear in the Networks/IPs section under VPC Networks (10).
Step 4. Tier network created successfully
Summary and recommendations
You now know how to successfully configure a VPC on the Jotelulu platform. If you eventually would like to create a VPN between two VPCs on Jotelulu, simply create another VPC that is not on the same network. For example:
- VPC Name: VPC2
- TIER Name: TIER2
- Network: 10.2.0.0/16 (unlike the VPC1, which was 10.1.0.0/16)
For more information about how to create a VPN between two VPCs on Jotelulu, have a look at the tutorial entitled: How to Create a Site-to-Site VPN Tunnel on Jotelulu.
Finally, it is also worth mentioning that you also have the option to connect your VPC with VPCs hosted by other cloud service providers or even to Cisco ISR devices running IOS 12.4 (or later) or Juniper J-Series routers running JunOS 9.5 (or later).
Glossary:
- VPC (Virtual Private Cloud): Set of shared IT resources assigned to a public cloud environment, that provides a certain level of isolation between the different organisations using said resources. A VPC can act as a container for multiple isolated networks that can communicate with each other through a virtual router.
- Network TIER: Each tier or subnet acts as a separate network with its own VLAN, where you can locate groups of resources, such as virtual machines. These tiers are segmented through VLAN.
- VLAN (Virtual Local Area Network): A network that makes it possible to separate the logical segments that make up a LAN and that do not need to communicate with each other across the local network.
