Cloud computing technologies have brought enterprises of all sizes to the forefront of the biggest technology revolution to date. Cloud solutions are on track to completely alter enterprise IT, and disrupt the way that organizations do business.
As a result of the shift to the "as a service" model, application performance has had a direct impact on business productivity. Consequently, CIOs have realized that traditional networks are not cut out to handle the shift to the cloud; thus network connectivity has also seen a transformation. To keep up with the demands that cloud computing has placed on the network, Software-Defined WAN (SD-WAN) has emerged to augment legacy network connections.
Amidst this revolution, the SD-WAN market has seen tremendous growth. IDC Analysts estimate that the SD-WAN market will reach 1.19 Billion this year and is expected to maintain a CAGR of 69% over the next 5 years. With this kind of success, CIOs are asking why and how they should use SD-WAN. There are several reasons, let's explore:
Agility and Deployment
While traditional MPLS connections are rigid and take a lot of time and resources to deploy, SD-WAN solutions are not. SD-WAN simplifies deployment because it does not take a skilled network engineer to install. In fact, SD-WAN can be remotely delivered and installed, with no need to send IT personnel on-site.
Additionally, SD-WAN allows users the flexibility to incrementally add resources and interoperate within existing devices and circuits.
With SD-WAN, you get the benefits of a reliable and secure WAN service at internet price points. Not only is the solution itself affordable, but it reduces costs in other areas. SD-WAN leverages cloud gateway-based architecture, which reduces or eliminates the need to pay for expensive data center upgrades, recongiguration and equiptment replacement. Additionally, the virual configuation of SD-WAN removes the costs associated with truck rolls to the branch site.
SD-WAN allows enterprises to own the network connection; and this becomes crucial when mission critical data is being transferred outside of the companies firewall. IT organizations can leverage SD-WAN connections and implement a multi-layered security model, ensuring the secure transfer of data.
The primary benefit of shifting to a cloud-based network strategy is to achive fast and reliable application performance. By augmenting traditional networks with an SD-WAN solution, assures performance and reliability for the most demanding real-time apllications and enables direct access to cloud applications.
The shift to the cloud is something that enterprises need to consider if they would like to stay competitive. With the benefits of cloud computing outweighing the costs for a majority of industries, a migration to the cloud is inevitable. With this in mind, SD-WAN's role in IT will continue to see growth, and it is up to CIOs to ensure that they prepare their organizations fully for the transition to cloud-based services.
