The Current and Future State of SDWAN: Part 2 of 2

In our last blog, we defined what SDWAN is and the current state in which we interact and use it. For the second half of this two-part series, we’ll look at the future state of SDWAN and how you can make the most of where it’s going.

1. Future state of SDWAN

The future for SDWAN is like most of your technology — it will only get better from here. According to Cisco, it will allow you to quickly connect all company data centers, core and campus locations, WAN branches, colocation facilities, cloud infrastructure and remote workers. SDWAN is also a critical piece of your networking that provides the security and efficiencies to optimize how you connect your campus to applications — whether they reside in your private or public cloud. So not only is SDWAN becoming more widely adopted across industries (resulting in higher productivity and lower IT costs) but it is also completely transport independent and able to operate over technologies such as the Internet, MPLS or 4G/5G in order to enhance networks across the spectrum of use. There’s a general misconception that MPLS is a thing of the past but a lot of companies still use it so don’t go in and rip it out. The evolution of MPLS and SDWAN go hand in hand. You can use SDWAN to enhance, layer or augment your MPLS to improve network capabilities and potentially lower costs that you spend on MPLS.

Furthermore, SDWAN helps ease the pain of including wireless network connections as part of a larger WAN strategy and it eases some of the complexity of how the various forms of access will be used.  The long story short is SDWAN makes your wireless network more secure and allows for better use.  Wireless network 4G or 5G implementation can use SDWAN as a springboard to enhance data flow and deliver value-added intelligence to a collective transport strategy by combining the capabilities between wireless and any hard-wired access.

The common denominator in all these technologies is the cloud.  Cloud edge is evolving and with it, so are data centers and how data is pushed from point A to point B. Everyone is moving towards consuming higher and higher amounts of cloud-centric services and we all know it’s a multi-cloud world we live in. SDWAN is the underlying vehicle to help adoption of cloud-centric services because it provides the foundational architecture to optimize and secure how you reach and access those cloud services. Implementing SDWAN with a multi-cloud, however, is a strategic conversation that organizations need to have with experts in order to plan for the future of secure data.

2. How to make the most of SDWAN

The most valuable thing SDWAN offers is that it helps you optimize, streamline and ensure security: your network must evolve to support the new applications and devices that are added each day. With today’s push towards modernization, your legacy network infrastructure is most likely no longer ideal for the new demands of essential applications, cloud migrations, mobility, virtualization and the management and access of critical assets driven by the Internet of Things that end users depend on.  Your IT team needs more flexibility and a single view of traffic to ensure performance measures and expectations are met. To do this, IT teams are being forced to look at their networks in a new way, but sometimes the roadmap isn’t clear.

Iron Bow can help you identify your current state and assist you with development of a go forward plan that is future proof because we look at your network in the context of your specific business goals. Our expertise provides that tailored roadmap of products and integration techniques to help you chart the best path forward to the next generation network, whether that means on premises, via the cloud or in a hybrid model.

Our teams do this day in and day out and come with the knowledge you need with not only SDWAN, but software-defined networking (SDN), data center networking, LAN/WAN infrastructure, wireless networking and programmability (including orchestration and automation). When you’ve been around as long as we have, you know everything within your network is tied together. To be prepared for a productive (and cost efficient) future, take the steps to ensure your current and future state SDWAN network is doing the most for you.
