What is Cloud WAN and what’s its impact on Cloud Networking?

Everything today can be delivered “as-a-service” to customers or end-users via networked “things” over the Internet. Even IT infrastructure is delivered ” as-a-service” – servers, storage, databases, networks, software, analytics, intelligence, and more. Moving to a multi-cloud ecosystem across differently deployed clouds (public, private, and hybrid) helps enterprises become more agile, efficient, and service-oriented. All this results in a lot of pressure on the enterprise network (WAN). With cloud computing playing a critical role in the digital enterprise, networks need to be cloud-ready – flexible, fast, scalable, and secure. 


Enterprise spending on cloud computing is on the rise. Cloud IT infrastructure spending increased to $57.2 billion, up 21.3% year-over-year. 

What do we mean by Cloud WAN?

Traditional network infrastructures (like MPLS) were never meant to meet the economics and flexibility of cloud technology. Cumbersome, complex configurations, high cost, and low performance (backhauling Internet traffic into DCS) at the branch office or remote site have made MPLS inadequate to meet today’s changing needs WAN. 

The rise of cloud models has subjected traditional methods in IT businesses. It is responsible for what is happening on networks today – new infrastructures, bandwidth-intensive applications and devices, and new types of cloud traffic. No matter what the demand, the enterprise network should deliver seamlessly and consistently. 

Why is CLOUD WAN crucial for cloud computing?

1 .  Enterprise Network Virtualization

CLOUD WAN enables enterprise network virtualization, which IT can use to create a unified fabric of all connected cloud services – storage, WAN, DCS, wired and wireless LAN, etc. These cloud networks feature tremendous flexibility and scalability and provide consistent policy delivery across the distributed enterprise ecosystem. By virtualizing networks over CLOUD WAN, IT can manage and handle any traffic flow, including to the cloud, from a central orchestrator. 

2 . Using CLOUD WAN for network automation 

CLOUD WAN can direct traffic based on policy. It provides the business flexibility needed to get maximum value from cloud services. With CLOUD WAN, end users can automatically connect to cloud services over the best available connection. Traffic is defined by policy and automatically routed over the best path based on business needs, security requirements, and the current state of the network. It eliminates the need for hectic and tedious manual configuration. 

3 . Delivering Security with CLOUD WAN in the Cloud 

CLOUD WAN enables IT teams to use cloud security as a service. CLOUD WAN can selectively route traffic to the appropriate cloud security service while providing embedded security services such as firewalls, VPNs, and user segmentation. In addition, CLOUD WAN and its security features are becoming key to secure cloud connectivity with the rise of multi-cloud ecosystems. 

 4 . Manufacturing Networks Cloud-Ready with CLOUD WAN 

Digital transformation, adopting a cloud-first strategy, and optimizing cutting-edge technology all have one reason: Bespoke Customer and User Experience. All these initiatives are worthless if the customer and user experience are poor and inconsistent. That’s why CLOUD WAN is at the heart of digital transformation today. CLOUD WAN provides detailed insight into application performance, network flows, and congested paths. It gives IT helpful information about the users and devices connected to the network. 

 

Why is Cloud WAN crucial for Cloud Computing?

Conclusion

As the demand for cloud computing services continues to grow, most enterprises are adopting a cloud-first strategy. The cloud has made the current traditional technologies, if not obsolete, a significant impediment to the digital transformation of enterprises across the globe. No wonder most enterprises have either switched to CLOUD WAN or are planning to switch shortly.
