By leveraging cloud-based infrastructure, platforms, and services, organisations can build, manage, and optimise their networks more efficiently and dynamically.
FREMONT, CA: Cloud networking utilises cloud computing and network resources to deliver networking services and capabilities. Instead of relying on local servers or personal devices, cloud computing allows users to access and utilise these resources remotely, on-demand, and as a service. It also consists of leveraging cloud-based infrastructure, platforms, and services to build, manage, and optimise networks. In cloud networking, traditional networking functions such as routing, switching, firewalling, load balancing, and virtual private networking (VPN) are virtualised and delivered as a service. This enables organisations to build and manage their networks more efficiently and dynamically.

The Functioning of the Cloud Networking
In cloud networking, the network might be either completely cloud-based or just cloud-enabled.
For cloud-enabled networking, the network is generally present on-prem, but some, or perhaps all, resources that are used in their management are on the cloud. The core of the network infrastructure, which includes packet forwarding, routing, and data, remains in-house, and other aspects of the network, such as monitoring, network management, security services, and maintenance, are executed via the cloud. One example is utilising the SaaS-based firewall to safeguard an on-premises network.
The entirety of cloud-based networking is in the cloud. This also comprises network management resources, as well as physical hardware. The cloud-based networking is utilised to deliver connectivity between resources and applications in the cloud.
The Cloud is Transforming Traditional Networking
Individuals who use digital devices and applications daily require dependable and secure access to the applications and data. However, the allocation of services and applications across physical data centres and the cloud is generating new obstacles for IT. Conventional application delivery controllers (ADCs) and load balancing are no longer enough for providing applications in a multi-cloud and hybrid world.
Additionally, as applications are being moved to the cloud, companies have also become more vulnerable to internet-based attacks. To resolve this concern, organisations are no longer associating themselves with the model of ‘connect first, then authenticate’ users. Instead, businesses are implementing a secure digital perimeter, which consists of web application firewalls, ADCs, and secure web gateway components, and using this perimeter to authenticate the user before granting access on another basis, such as their identity, location or the device they are using.
Ultimately, employing different solutions for each application across hybrid or multi-cloud environments can be challenging to obtain and manage. It’s important to obtain end-to-end visibility and analysis of users, applications, and devices across the network. Cloud networking empowers organisations to leverage the advantages of cloud computing to optimise and streamline their network infrastructure, resulting in enhanced scalability, cost savings, agility, and simplified management.
