Cloud networking is a kind of network where the cloud hosts all the network resources. However, the cloud can be private, public, or hybrid. The resources provided by the cloud provider are firewalls, bandwidth, and virtual routers. The customer can access these networking resources over the Internet.
Cloud networking leverages the organization in extending its computing infrastructure that improves its services at a reduced cost. Let’s proceed with the content.

What is Cloud Networking?
Cloud networking is one where all the network resources are in the cloud environment. Cloud networking is a technique of resource sharing where the resources are:
- Other computing resources
These resources are in different locations and shared over the network.
Whenever any user tries to execute any application over the cloud network, the required resources are made available to the application over the cloud network. All the resources are connected via the Internet. However, the performance of a cloud network plays a major role in the performance of any cloud computing application. But what was the need for cloud networking? Let’s find it out.
Why is it Required?
Modern businesses require an agile network that can provide faster computing solutions. Cloud networking offers a computing solution that can be monitored and managed remotely. With this, the computing solutions it offers are fast and secure.
Cloud networking leveraged organizations to increase their computing infrastructure, regional expansions, and data redundancy plans. So, many companies, organizations, and enterprises are nowadays opting for cloud networking.
How does it Work?
Cloud networking is nothing but the IaaS service offered by cloud computing. Here the cloud provider offers you all the networking capabilities and resources. They provide these services on demand, and you can pay-as-you-go over the Internet or any dedicated network.
As the cloud network is set up using the cloud services, it sets up differently depending on the kind of services offered by the provider.
For example, the customer can control and manage the entire cloud network with a private cloud. The customer can control the hardware and software on which the cloud is built.
In the public cloud, the customer can control and manage the cloud networks if the cloud is deployed using an IaaS service. And if the network is deployed using the SaaS or PaaS services, the customer cannot control or manage the cloud network. It is the cloud provider that entirely controls and manages the cloud network.
How Secure is Cloud Networking?
The cloud networking resources are hosted by a third-party provider that we refer to as a cloud provider. So as the host is a third party, security is a major concern when opting for cloud networking. Because all your data, may it be a file, photo, video, etc., is stored on a server that’s beyond your control. And you are totally unaware of how vulnerable these servers are to attackers.
This network is far more secure than your local network. Because they are the large companies that host the cloud services, so, they are more robust when it comes to security. The host of the cloud services takes appropriate measures for the security of the cloud network.
Types of Cloud Networking
We can classify cloud networking into two types, as discussed below:
- Cloud-enable Networking – It is a kind of networking with core network infrastructure on the customer’s premises. However, the rest of the network resources required for cloud networking are located in the cloud. The core network infrastructure on the customer’s premises is packet forwarding, routing, data and other networking services. The remaining network resources in the cloud are network management, administrative processes, monitoring, maintenance and security. For example: Let us consider a firewall, a SaaS service, i.e. a cloud-based networking resource. The firewall is implemented on the customer’s computer to protect his non-cloud network. Thus, it is cloud-enabled Networking where the firewall, a networking resource, is installed on customer premises but regulated and maintained by the cloud.
- Cloud-based Networking – In cloud-based Networking, the entire networking resources are located on the cloud host premises. The cloud-based Networking offers connectivity between cloud applications and all the networking resources in the cloud.
How Cloud is Changing Traditional Networking
Cloud networking is continuously evolving and creating new challenges for network architects. The main concern of every network user is that they can have reliable, fast and secure access to the application or data they use daily.
Traditional Networking is secure because the data owner has complete control over it and its transmission. But for the traditional networking model, we have to purchase the entire setup for Networking, such as hardware & software, and update them regularly. Buying and maintaining the entire setup can be tedious even for the big companies with skilled IT teams.
Thus, a cloud came up with solutions to the problems of traditional Networking. With cloud networking minimum of the user-owned resources are involved. All the network resources, i.e., hardware and software, are in the cloud environment.
In cloud networking, users can use these resources whenever they want to on a pay-as-you-go-basis. This is how cloud networking is changing traditional Networking.
Benefits of Cloud Network
- It reduces the cost of purchasing and maintaining the network resources.
- Business can easily scale their network infrastructure.
- The cloud network is agile and provides you with resources and solutions quickly.
- The cloud network is reliable and secure.
So, this is all about cloud networking, where the cloud providers host the entire network resources. Cloud networking is an IaaS service.
