SD-WAN: The Next Level Of Growth @ edge
2019-07-03The IT services industry has been going through a transition phase since the beginning of 2018. The industry is way past the point when it was expected to just implement and maintain IT applications. Today, the need of the hour is to be more aware of various business areas and create innovative digital experiences for the customers. The adoption of newer technologies such as IoT, AI and more recently blockchain has also pushed the industry to reskill itself as well as hunt down new talent that can help it survive.
"Changes are happening in the IT services space and we are talking about disruptive technologies like AI and blockchain, which is causing so much of change. Clients really need help from service providers in regard to how technology can advance their business goals in the best possible way. SD-WAN implementation which is tailored to Indian business needs around data security, last-mile-connectivity and performance monitoring. Indian IT industry in the face of constant disruption. This is needed so that organizations can make the best use of technology and human resources and become agile in all processes. Executives need to realize capabilities to make the shift to ‘digital’ and develop an understanding of what digital shift in an organizational context entails.
VARINDIA, has witnessed the growth of SD-WAN evolution, which requires integrated security. Since, Cloud is driving fundamental changes in how networks are built, which requires a more flexible network architecture that can accommodate and secure connections to multiple clouds. SD-WAN, or Software Defined WAN, is the concept of using software-based controllers on top of existing WAN architecture, to access better bandwidth, optimize traffic, control and manage the network via single portal and thereby dramatically improve network performance. SD-WAN enables the broader goal of enterprises connecting users to applications in a cost-efficient WAN topology. This will also help enterprises’ branch offices to route traffic to the internet where a more expensive MPLS line is not necessary.
It is true that, SD-WAN is providing connectivity from the enterprise edge to the cloud, with use cases showcasing successful deployment. Edge connectivity, allowing compute to move closer to users and things such as in the enterprise branch office, is driving a re-think of the enterprise WAN. Rather than an architecture based upon branch to corporate connectivity and branch services provided by standalone appliances, enterprises are moving to shared communication and compute infrastructure with services chained together providing traditional functions such as security, load balancing, SD-WAN, WAN optimization, etc. This new architecture for networking and compute at the enterprise edge will allow for rapid deployment of new applications, increased performance when connecting the enterprise edge to corporate operated DCs or the multi-cloud, comprehensive monitoring and control, and reduced capex and opex.
The worldwide data center SDN market will be worth more than $12 billion in 2022, recording a CAGR of 18.5% during the 2017–2022 period. The market generated revenue of nearly $5.15 billion in 2017, up more than 32.2% from 2016. As per IDC. Software-defined networking (SDN) established a foothold in cloud computing, intent-based networking, and network security, with Cisco, VMware, Arista, HP Enterprise, Juniper, Extreme Networks and Huawei are the leading players in the industry.
SD-WAN and security are in the midst of an evolution that will grow in importance and dominate the WAN Edge landscape for many years to come. That’s because cloud is driving fundamental changes in how networks are built, which requires a more flexible network architecture that can accommodate and secure connections to multiple clouds. Here the customers can see all of their devices and TCP flows, which means they can slice up the network from the data or management plane to support a variety of applications and configurations. With this users can more easily segment an IoT application from the production world if they want.
Now with the transformation of WAN with a vision to elevate the quality of life for consumers by offering unparalleled convenience. Organisations like large Insurance, Banks and Retail sectors gone under Network transformation to meet the demands of the cloud era and have achieved key goals for WAN transformation by deploying SD-WAN solution across its multiple branches. Next Gen WAN was the need of the hour to improve network performance and to eliminate long procedural challenges of new service provider contract roll-outs.
As the opportunity is knocking the door, Enterprises around the world tap into the growing world of cloud applications. It dynamically reallocate network resources and use software defined policies to manage network traffic. SD-WAN effectively takes your WAN to a significantly higher level of speed, consistency and control.
Lastly, SDWAN brings forth the next generation WAN connectivity solution for Indian enterprises in today’s cloud centric environment where agility, flexibility and ease of management of entire network from a single user interface are paramount, and all this is delivered by reducing the overall TCO of the entire network.
