Add Network Interfaces

Adding a new network interface to an instance in a cloud service is a powerful capability that enhances the networking flexibility and functionality of your cloud-based resources. In cloud computing, network interfaces (often referred to as network cards or NICs) are virtual network adapters that connect instances to networks, enabling communication with other instances, services, and external resources.

The ability to add a new network interface to an instance offers several advantages:

  1. Isolation and Segmentation: Adding network interfaces allows you to segment your instances into different networks or subnets, improving security and network isolation. This can be particularly useful in complex architectures.
  2. Enhanced Security: Network interfaces can be associated with specific security groups or firewall rules, providing fine-grained control over network traffic to and from the instance.
  3. Load Balancing: Multiple network interfaces can be used in conjunction with load balancers to distribute incoming traffic across instances, improving scalability and availability.
  4. High Availability: By attaching network interfaces to different network paths, you can enhance the availability and redundancy of your instances. If one network interface fails, traffic can automatically fail over to another.
  5. Routing and Networking Optimization: Additional network interfaces can be used to implement custom routing and networking configurations, such as creating a VPN gateway or implementing complex network topologies.

Getting started

Pre-requisite: Make sure you have available Private Network in same region with your VM/Instance. Refer to this document: Create Private Network

  • Start by login to your account and navigate to Instance details. Click on Network Interface tab and ‘+’ button.

  • In the “Create network interface” form, choose available network from the dropdown and click on ‘Save’ button.
  • Network interface successfully added to your instance
