3 Guidelines for a Productive SD-WAN Deployment



You’ve most likely heard of SD-WAN by now, and possibly your company has SD-WAN adoption in the books for your IT approach this year.


The benefits are difficult to ignore: automatic provisioning, complete network visibility, centralized management, price savings and much more.


On the other hand, migration is no effortless undertaking and needs thorough planning and preparation to make sure that SD-WAN delivers the outcomes you are on the lookout for. Such a large-scale network transformation may cause disruption and introduce business risks.


So, how are you able to anticipate network alterations and reduce disruptions? Read on for guidelines on how to prepare for a profitable SD-WAN deployment. Get a lot more info about considering SD-WAN providers


1. Assess your network specifications and requirements


Prior to receiving too caught up in the benefits of SD-WAN, take a close look at your existing network infrastructure and ascertain what kind of network you might be planning to create.


Ask oneself this query: What am I wanting to obtain with SD-WAN?


In case your aim would be to reduce expenses, calculate the anticipated savings and return on investment. Take into account your number of sites, average bandwidth per site, router costs and WAN optimization costs. If you are searching for greater flexibility, plan for the integration your access devices, communications infrastructure, applications, communication tools and security. Figuring out your targets will ascertain the type of SD-WAN solution your company demands.


Additionally, evaluate your network to ensure that SD-WAN implementation doesn’t disrupt your current networks and operations in order that you'll be able to migrate as seamlessly as you can.


2.Make security a leading priority


As with any other networking architecture, SD-WAN security ought to be a leading priority.


Diverse vendors give different security options, and there is no normal for how security is constructed into SD-WAN. Some vendors use an overlay based on IPSec VPN and other folks may use third-party SaaS security systems. However, offered the number of cybercrimes today, these might not be sufficient to prevent attacks on your network. Fundamental security options like Layer-3 firewalls could not be adequate for your company to secure all branches either. So, be sure to evaluate your SD-WAN vendor’s encryption and firewall characteristics. If essential, use separate products for security in the branch.


One option could be the zero trust model, which treats any user or network attempting to access its systems as untrusted. Adopting this model requires you to leverage an application-centric security policy, at the same time as micro-segmentation of your customers, applications and services, and granular perimeter enforcement.

Lastly, run pilots for unique areas and applications to discover challenges and identify whether or not the network design supports your traffic flows and application priorities. This will likely also enable make sure that you are using the correct network access varieties.


Running pilots is important, as it will assess the resilience of your SD-WAN under the tension of high traffic volume and check whether high-quality of service (QoS) might be maintained beneath these situations. Recognizing these factors will help you accelerate a full-scale SD-WAN deployment across the complete company.
