Benefits of virtual networks

Virtual networks are a must for deploying any meaningful IaaS solution. Virtual machines cannot be provisioned without virtual networks. Apart from being almost a mandatory component in solutions, it brings great architectural benefits and the most important among them are the following:

• Isolation: Most application components have separate security and bandwidth requirements and have different life cycle management. Virtual networks help in creating isolated pockets for these components that can be managed independently of other components with the help of virtual networks and subnets.
• Security: Filtering and tracking who is accessing resources is an important feature provided by virtual networks. They can stop access to a malicious IP address and port.
• Extensibility: Virtual networks act such as a private LAN on the cloud. It can also be extended into WAM by connecting other virtual networks across the globe and can be extended as an extension to on-premise data centers.
