¶ About Shared Networks
In an IaaS cloud environment, networking plays a crucial role in facilitating communication between instances and the public internet. Networking is a distinct component, offering various configurations to support seamless connectivity. One notable feature is the provision of guest networks, which enable instances to interact both internally and externally. These guest networks, existing alongside storage and management networks, serve as the backbone for communication among virtual instances.
Within our IaaS Cloud, there are two primary types of guest networks: Isolated networks and Shared networks. While Isolated networks provide dedicated environments for individual instances, Shared networks allow multiple instances across different accounts to access the same network resources. Additionally, the platform offers the flexibility to create Virtual Private Clouds (VPCs), enabling the grouping of instances into separate tiers with unique IP subnets.
Instances can be assigned to both shared and isolated networks simultaneously, allowing connections across multiple networks at the same time. Each network connection results in the creation of a separate virtual network interface on the instance. However, for instances with multiple networks, manual configuration is necessary to ensure proper routing.
In our cloud environment, shared networks can be created by either end-users or administrators. Furthermore, administrators have control over Shared Network resources, including VLAN and physical network mappings. Additionally, the platform supports Source NAT per account within Shared Networks, contributing to efficient network management.
Overall, the networking capabilities within our IaaS cloud platform offer a robust framework for facilitating communication and resource allocation, empowering users to configure and manage networks according to their specific requirements.
¶ Creating Shared Networks
Follow these steps to create a new Shared network:
1. Navigate to Network → Guest networks on the left navigation bar.
2. Click on Add network in the top row:
3. Click on the Shared tab to access the appropriate network settings, then specify the following parameters:
- Name of the Shared network.
- Short Description text of the network.
- Zone of the network.
- Decide the Scope of the Shared network by assigning it to a domain, account, or project.
- Select an appropriate Network offering.
If the offering list appears empty, please contact us, and we'll provide further instructions and assistance.
- Optionally, you can configure IPv4 settings by specifying the Gateway, Netmask, and IPv4 range.
- Optionally, you can also configure IPv6 settings by specifying the Gateway, CIDR, and IPv6 range.
- Custom DNS suffix for the Network domain.
- Whether or not the IP address usage should be included in the API request.
4. Click on OK to save and create a shared network.
¶ Managing Shared Networks
¶ Update Shared Networks
To update a shared network, follow these steps:
1. Navigate to Network → Guest networks on the left navigation bar.
2. Select a specific shared network from the list view.
3. Click on Update network in the right top action toolbar:
4. Here, you can update the parameters configured during the creation process.
5. Click on OK to save and apply your changes to the shared network.
¶ Restarting Shared Networks
To restart a shared network, follow these steps:
1. Navigate to Network → Guest networks on the left navigation bar.
2. Select a specific shared network from the list view.
3. Click on Restart network in the right top action toolbar:
4. Optionally, you can decide if you want to Clean up or Live patch the shared network.
5. Click on OK to restart the shared network.
All services provided by this network will be interrupted.
¶ Deleting Shared Networks
To delete a shared network, follow these steps:
1. Navigate to Network → Guest networks on the left navigation bar.
2. Select a specific shared network from the list view.
3. Click on Delete network in the right top action toolbar:
4. Click on OK to confirm and delete the shared network.
Ensure that all instances are removed before deleting a shared network.
