Virtual Routers in Cloud Networking

Virtual Routers

• Virtual routers are software-based devices that route traffic between different Virtual Networks (VNs) and on-premises networks.
• They provide similar functionality to traditional hardware routers, allowing for complex network topologies.
• Virtual routers can be configured to route traffic based on different criteria, such as IP address, subnet, or port.

Cloud Network Management

• Cloud network management involves monitoring, troubleshooting, and optimizing your cloud network.
• Cloud providers offer a variety of tools for managing your network, including monitoring network performance, identifying and troubleshooting issues, and configuring network settings.

Subnets

• Subnets allow for further segmentation of your network traffic and improve security.
• Subnets can be created with different security groups and routing configurations to control traffic.
• For example, a separate subnet can be created for web servers, database servers, and application servers, with different security controls applied to each.

Security Groups

• Security groups act as virtual firewalls that control inbound and outbound traffic to your resources.
• Rules can be defined to specify which types of traffic are allowed and which are blocked, based on source, destination, port, and protocol.
• Security groups can be attached to individual resources or entire subnets, providing flexibility for different security needs.

Internet Gateways

• Internet gateways provide public access to your resources from the internet.
• They act as the entry and exit point for internet traffic, allowing users around the world to access your resources.
• Multiple gateways can be created for different VNs.

Cloud Network Architecture

Virtual Networks (VNs)

• Virtual networks are the foundation of cloud networking, providing logically isolated environments for your resources.
• VNs can be created, managed, and destroyed as needed, allowing for isolation of resources from other tenants in the cloud.
• VNs can be public or private, with different levels of access control depending on your needs.

Why Virtual Networks?

• Virtual Networks act as a communication channel between resources launched in the cloud.
• They are necessary because there are no actual routers or switches in the cloud, allowing resources to interact with each other.
