Reducing network complexity is one of the primary reasons why organizations implement software-defined WAN (SD-WAN) solutions. In a recent IDC study, rapid deployment, operational efficiency and reduced complexity scored high as motivational factors for organizations considering SD-WAN deployments. The ability to simplify WAN infrastructure was a top SD-WAN use case.
In theory, SD-WAN delivers on this promise. SD-WAN sits on top of multiple WAN links, using software-driven policies to automatically select the best data transport mechanism for each application. As such, SD-WAN masks the complexity of implementing and managing an aggregate WAN and frees IT from the virtually impossible task of implementing those policies manually.
But that’s only one aspect of WAN management. Most organizations are struggling with a complex array of WAN equipment, including routers, load balancers and other gear along with firewalls and other security appliances. SD-WAN becomes yet another box IT has to deal with.
Furthermore, the cost-saving benefits of SD-WAN only manifest themselves when you connect branch locations directly to the Internet as opposed to backhauling Internet traffic to headquarters via a private circuit. With direct Internet access, security becomes an even greater concern, so additional security solutions are typically needed. The branch WAN stack grows larger, and maintaining user accounts takes more time.
And when broadband Internet links enter into the mix, IT has to worry about application performance—particularly for latency-sensitive applications such as voice and video conferencing. However, troubleshooting performance problems becomes more difficult given the fragmented nature of the WAN.
Doesn’t sound so simple, does it? Plus, you’re adding a new technology (SD-WAN) that the IT team isn’t familiar with, and changing WAN management processes.
Some organizations try to sidestep these issues by going with a managed SD-WAN solution through their telecom carrier. However, this approach increases costs and makes it harder for organizations to respond to changing business and IT requirements.
With InSpeed Quality Service (IQS), you get all of the benefits of a managed service in a carrier-independent model. Designed for rapid deployment and ease of use, IQS consists of a small onsite appliance that routes WAN traffic through a secure VPN tunnel to the InSpeed cloud. The cloud service automatically shapes the traffic entering and leaving the site, giving priority to interactive traffic such as voice and video conferencing. It also manages bandwidth utilization from end to end, ensuring optimum performance for all applications.
IQS enables secure site-to-site connectivity without the need for private circuits or complicated firewalls. It also supports multiple WAN connections for business continuity, automatically switching to a backup link while maintaining Quality of Service.
Installation of the IQS appliance is plug-and-play simple, and the cloud service does all the heavy lifting without the need for complex configuration or policy management. It’s so easy you can use it in all of your sites, including the home offices of your remote workers.
SD-WAN is supposed to relieve complexity, so many organizations are wondering why it has to be so hard. It doesn’t. IQS delivers all the benefits of SD-WAN without any management headaches.
