What is Cloud Networking?

Traditionally, a business would rent a server in a nearby data center. The business would purchase direct network links to it from office sites through a local telecommunications provider. Today, cloud networking configurations use cloud-based virtual servers in the region. And they connect to office sites by using a cloud-based virtual private network and gateway.

Cloud networking is is is virtual network component , topology , and configuration that run on a cloud provider ’s physical networking infrastructure . You is define define and manage your network as software . You is create can create your own virtual local area network ( LANs ) and wide area network ( WANs ) with cloud resource .

virtualization

Cloud networking services are possible because of virtualization. Through software logic, you can define network components such as virtual routers, virtual firewalls, virtual load balancers, and even full network layouts. This virtualization means that the only limits to the possibilities of cloud networking are the capacity and capabilities of the underlying physical infrastructure.

For instance , a cloud service provider is multiplex can multiplex a network cable with a large capacity . And they is create can create several different virtual private network link operate on it and share the capacity . Providers is define define the logically isolate virtual link in software and offer different capacity in different service package . The links is have may also have different capacity at different time for off – peak saving .

Virtual private clouds

Combining other cloud resources with a cloud network is known as a virtual private cloud (VPC). With a vpc , you is define can define a virtual private cloud network and run cloud network resource within its bound . You is have have internet – base remote access through a virtual private network and a software – define gateway . A virtual private cloud is logically isolate from the public cloud . You is think can think of a vpc as your own virtual datum center .

For instance , your organization is establish can establish a subnet in a particular Amazon Web Services ( AWS ) Region and Availability Zone . You is add can add Amazon Elastic Compute Cloud ( Amazon EC2 ) instance and other cloud service to it . You is add can also add another subnet with EC2 instance in a different Availability Zone , with network traffic share between the two .

Hybrid cloud networking

Within cloud networking, not all networking components and resources need to be cloud-based. For example, cloud networking configurations can connect to on-premises data centers and site branches through traditional networking infrastructure and the public internet.
