What is Cloud Networking? Is it better than traditional IT networking?

Cloud Networking is an IT infrastructure that enables a business to run some or all of the network resources on the cloud. Businesses can host networking on a private or public cloud in order to provide better connectivity between apps and workloads spread across:

  • Cloud-based services like IaaS, PaaS or SaaS.
  • On-premises data centres.
  • Co-located facility.
  • Edge computing services.

While it still remains optional for some use cases, this strategy of networking is vital for efficient performance and management of hybrid and multi-cloud environments.

Cloud Networking

How does it Work?

Cloud Networking allows a business to design, configure and manage the network resources in the cloud. A company could create any virtual networking resources that the system requires, including:

  • Adapters.
  • Content delivery networks (CDNs).
  • Data connectivity.
  • Domain name systems (DNS).
  • Firewalls.
  • Gateways.
  • Routers and switches.
  • Virtual bridges.
  • Virtual private networks (VPNs).

Businesses have 2 options while choosing where to set up cloud-based network resources:

  1. Use private cloud -> Private cloud offers higher flexibility in the overall networking design.
  2. Use public cloud -> If a public cloud offers to host a network, it allows the consumers to control and manage the setup in only the IaaS based deployments.

Once the setup is complete, the cloud provider offers centralized management, control and, visibility across all the networking resources.

If a company want to manage this in-house, it requires many elements such as collaboration between the stakeholders and teams, most notably:

  • Cloud Architects.
  • NetOps.
  • SecOps

Cloud Networking Types

1) Multi-Cloud Networking

Multi-cloud networking allows the design, deployment and, operation of a network between multiple cloud networks. The goal of Multi-cloud networking is to make sure that there are consistent networking policies across all the cloud networks.

2) Hybrid Cloud Networking

Hybrid cloud networking allows data transfers between the on-site networking resources, private clouds, and public clouds. The term hybrid commonly reflects connectivity between public and on-site data centres.

Hybrid cloud networking allows a business to keep critical apps and data under the on-site direct control while still using the cost-efficiency and flexibility of the public cloud offerings for less sensitive cloud networking operations.

Hybrid Cloud vs Multi Cloud: Detailed Comparison

Benefits of Cloud Networking

  1. Lower operational costs.
  2. Better networking performance.
  3. Better team productivity.
  4. Cheaper and faster scalability.
  5. More agile DevOps and NetOps teams

Advantages of its Software

A cloud networking software enables the team to design, set-up and, and manage a cloud network. This networking tool simplifies management, speeds up resource deployment, and increases visibility across all the environments.

The list below shows why businesses should consider using dedicated tools:

  1. High Security Across Hybrid Cloud Environments.
  2. Simpler and More Easier Cloud Migrations.
  3. A Centralized Network Management.

Challenges of Cloud Networking

While in many ways cloud networking is superior to the traditional setups, cloud networking is not free from challenges. The most notable problems with cloud networks are:

  • Vendor lock-in.
  • The lack of control.
  • Poor integrations between different environments.

Traditional vs. Cloud Networking Security

Traditional IT networking setups are among the most secure networking models in the entirety of their existence. Businesses get to tightly control the data and sharing processes without relying on 3rd-party vendors.

However, complete control doesn’t mean requiring fewer security measures, which is why most businesses setup:

  • Zero-trust security policies.
  • Strict firewall laws.
  • Reliable access control.
  • Robust user and employee auth protocols.
  • An Intrusion detection system (IDS).
  • Monitoring, anti-virus and anti-malware tools.

In a cloud network, a 3rd-party vendor hosts the networking resources, an arrangement that often raises various security concerns. However, there is a playthrough of security measures network architects can take on to keep a cloud network much safer.

Conclusion

When used correctly, the cloud networks could lower the costs, boost the agility, and, improve the performance. A cloud network could be a major turning point for businesses. A cloud network could also reduce operational costs, allows quick and easy scaling, and reduce downtimes.

Whether the businesses would like to go for a fully cloud-based network or combine the cloud resources with a local on-prem setup, the network performance and day-2-day management will both see huge improvements.
