Top 6 benefits of SDWAN

Enterprises are revolving around different business strategies and new technologies to be ahead in the game. Whether it is cloud or SaaS, mobility, BYOD, network security, or unified communications- every entrepreneur is in search of the best and latest tech. Among which, the cloud is most eminent. It has gifted certain presents to the clan of businessmen- easy data transfer among intra-geographical locations, ease of storage, etc. Along with these advantages of the cloud, its security plays an equally important role. Here enters SD-WAN, which provides:

  • Granular Security
  • Agile Network
  • Better Speed
  • Low Operating Cost
  • Higher UX, etc.

No doubt, SD-WAN is a hype in the current scenario. Even, many businesspersons have adopted it just because other enterprises have staffed it in their agendas. But, do you really know what is SD-WAN? What is this approach all about? Does it have the potential to assist you in solving your business problems? What does it possess that drives many organizations to turn their heads towards it? Does SD-WAN match the expectations of your business?

Let’s discuss what is SD-WAN, why it has turned up, and what are its advantages.

What is SD-WAN?

SD-WAN or Software-Defined Wide Area Network is an approach, which distributes the traffic that uses software-defined networking (SDN) technology across WANs to find out the best possible route for traffic flow among different geographical stations.

Technically, we can define that- SD-WAN is a technology that optimizes the operations over WANs with cloud-based management and automation.

Why does SD-WAN Emerge?

With continuous adoption of the use of SaaS/ IaaS applications, the graph of user experience has been degraded within a short period. This is being resulted in poor performance and reduced ROI. Plus, conventional MPLS circuits were designed as well to function in a branch with security constraints within that specific campus. That’s why SD-WAN appears to fix all these issues with these resolutions:

  • It makes processes more agile to improve the user experience.
  • It offers security and accessibility to cloud-based applications.
  • It has the potential to prioritize the traffic, automatically, according to its criticality on the cloud.
  • It is, literally, evolved for the companies with multiple branches and SD-WAN can handle critical branch office operations.
  • On the whole, SD-WAN comes into existence because it balances the proper management of the user experience, complexity, and security.

What are the Benefits of SD-WAN?

1. Upgrading Business’s Connectivity with Traffic Prioritization:

SD-WAN tech is all about the robust connection with full-fledged security. It allows the users to create a common network infrastructure, which accommodates different connections, such as- MPLS (Multiprotocol Label Switching), wireless LTE, or broadband. The user can enjoy this benefit easily- by allotting critical applications to robust connection, and less sensitive data to the public connection.

Moreover, this technology helps customers by removing the routing hardware and bringing the provisioning connectivity & services from the cloud on the platform. Even, you will also have the flexibility to scale connectivity up and down according to your prerequisites. In short, SD-WAN can easily upgrade the business’s connectivity among branches, headquarter, and the cloud.

2. Improved Edge-to-Edge Security:

Cybercrime is increasing day-by-day; and at some point, users can also ask the access to critical applications. This might be risky. SD-WAN takes care of each application at all branches. This technology has in-built security protocols along with encryption capabilities to ensure that only authorized person can access and/or view the specific application on the corporate network.

3. Network Agility with Increased Provisioning Times:

Flexible enough to diversify the bandwidth access using any local internet provider and to add newer sites easily and quickly. Also, you can increase the speed for any site (whenever it is required) by adding another connection, and upgrading the site licenses, since the bandwidth requires some changes within a particular time of interval. Hence, we can say that now, with SD-WAN, provisioning is no more peril to enterprises.

4. Increased Reliability and Responsiveness:

Links and speed both play an equivalently vital role in data transfer. Of course, links should be undisturbed, and the speed should be optimum (or, accordingly). Therefore, for gaining the utmost security, cloud-based application traffic uses direct internet connectivity to acquire a simpler and consistent performance on the cloud. Plus, the links’ health gets monitored after a span in order to keep your sites connected and all inbound & outbound actions go on smoothly.

5. Reduced OPEX:

Automation and self-managed protocols of SD-WAN scale down the requirement of external IT expert. Adding a new branch (anywhere) online is easy and can be accomplished in less time and cost. It can be done by- combining the efficiency of a centralized network management & automation with convenience & predictability of a managed service. Most appropriate for small/medium sized businesses, it, eventually, lowers the risk and total sum.

6. Higher Quality Data Transfer:

Not all applications have the same level of criticality. Some of them flow without any specific privilege, but others require higher quality and performance to match the pace of the expected user experience. SD-WAN selects the most appropriate route for specific traffic application. This helps spot the congestion points fast and divert the traffic to the less-utilized path.

Thus, traffic prioritization and congestion management assist in maintaining high-quality data/traffic.

Conclusion

Although SD-WAN is a new entity on networking interface, it is proving its 100% worth for cloud-based applications. So, today, the cloud with SD-WAN has become an essential component for an enterprise, isn’t it?
