Cisco SD-WAN Solution
SD-WAN technologies are being adopted at a rapid rate, replacing legacy WAN technology. It continues to be a hot trend for NetOps teams looking to drive IT change initiatives. In fact, according to recent research, 94% of organizations will have deployed SD-WAN within 2 years. Organizations that are slow to adopt transformative technology, like SD-WAN, are soon to be left in the dust by their digitally advanced competitors. But what can Cisco SD-WAN do for your business?
How SD-WAN is Transforming Networks
Major technology initiatives like cloud, NVF, IBN, SDN, edge computing, and more are transforming networks. The SD-WAN Cisco solution is impacting and changing network operations. According to research from IDC, the SD-WAN market will reach $4.5 billion by 2022.
But what is the impact on the bottom-line transport costs for businesses, and some of the key challenges and considerations to keep in mind if you decide to deploy Cisco SD-WAN solution?
What are the Benefits of SD-WAN?
Simply put, the Cisco SD-WAN solution automates wide area network environments and makes them more dynamic and secure. It can provide direct internet connection from a branch, enable teams to balance between multiple service provider and transport types more easily, and make intelligent adjustments to application paths for better performance.
But the most compelling part of the equation from Software-Defined WAN Cisco solution is the cost savings. Organizations’ can recoup close to 50% (or more) of the cost of traditional WANs and keep great service and a responsive network, all while NetOps teams save time.
Keep These Cisco SD-WAN Challenges in Mind
- Most large Software-Defined WAN Cisco solution deployments are phased and implemented at specific sites and then expanded slowly in a transforming network.
- This technology does not operate in a vacuum. It will likely have unexpected effects on application performance and existing infrastructure.
- Be prepared to manage the complexities of a mixed environment of legacy network components and the Software-Defined Wide Area Network solution until your transition is complete.
- SD-WAN Cisco solution is not a silver bullet, you still need to understand how traffic comes in and out of the various network fabrics and be able to find fix issues when they arise.
- You need visibility into the entire network to be able to properly manage and ensure SD-WAN solution performance.
- Your SD-WAN could have a different ISP for each site. This added path complexity requires good visibility.
Plan Properly with Network Monitoring
Cisco’s SD-WAN solution creates virtual networks using tunnels and remote sites, data centers, and the cloud. It requires granular visibility in the WAN. Unfortunately, built-in SD-WAN management platforms alone don’t provide the insight and context across multi-cloud, multi-domain, multi-fabric network environments you need for complete visibility.
Therefore, consider investing in enterprise network monitoring software. This will allow you to properly plan the deployment of an SD-WAN, confirm your Software-Defined WAN is working based on policies and performing as designed, and effectively troubleshoot, monitor, and manage the SD-WAN. It will also help eliminate cost on managing legacy network tools and speed your overall Mean Time to Resolution of issues.
