Why switching to SD-WAN is good for business

 In Hardware, Networking

If you’re a CIO or a business manager, you spend a portion of your time worrying about cutting expenses and how you can do so with as little impact to your business as possible.

One often overlooked area is your wide area network (WAN). If you don’t know how much your WAN costs you monthly, you should look into it. High-bandwidth MPLS circuits can cost thousands per month.

At the same time, businesses are demanding more flexible, open, cloud-based WAN technologies. They want a secure connection using high speeds at a lower cost.

That has been leading them to software-defined WANs (SD-WANs), which replace the more expensive MPLS solutions with lower-cost broadband internet connections for certain lower-priority traffic.

The days of having a single expensive MPLS circuit for your business are coming to an end. It’s time to think about having dual links and dual providers, making life easier for you and your IT staff. MPLS still has its place, but SD-WAN is here and ready to be a big time player in the WAN networking space.

Why you should be looking at SD-WAN

What are the benefits of SD-WAN, and why should you move my business over to this new service? Simple: cost savings, more network flexibility, cloud connectivity, and of course, enhanced visibility into applications and network performance.

Choosing a wide range of WAN services, such as MPLS, wireless, or broadband, allows you to connect all your geographically spread out locations while also having the choice to purchase services from different providers that meet your particular needs.

You can even choose to migrate to SD-WAN using a hybrid approach to make the change a little easier. You can keep your current MPLS using IP Sec VPNs and just use SD-WAN at select sites as you see fit.

These hybrid (MPLS and internet) networks support applications such as VOIP and tele-video, which will require certain MPLS features. You can use the high-speed broadband internet for all your lower priority applications.

How to get started with SD-WAN

Most businesses already have internet access in their offices, meaning all you must do is set up a network device at each of your remote locations, and a device or software can connect you to your current VPN infrastructure. You can even automate this process using SD-WAN.

Broadband internet doesn’t take months to order and set up like MPLS does. The key is to order two lines from two different providers to increase the reliability. Broadband internet SD-WAN also avoids any bandwidth penalties. It’s simple to upgrade without any changes required to your network or hardware appliances.

Not only does SD-WAN allow you to cost-effectively mix and match network links according to content type or traffic priority, it also adds the advantage of security. You can rest assured, knowing traffic will be encrypted end to end across the entire network (including the internet). All the devices and endpoints are authenticated using software-defined security measures.

SD-WAN also controls costs by removing expensive routing hardware and using cloud for connectivity and services.

Reap the benefits of SD-WAN

The benefits of SD-WAN are remarkable. Reduced recurring network costs, a more simplified management control, more visibility into the performance of your network, and Zero-Touch deployment methods are just a few of the advantages of SD-WAN.

Companies like Cisco, Riverbed, Aryaka, and CloudGenix are all now focusing on more “cloud-based” WAN offerings such as SD-WAN. If you’re in favor of lower costs, more flexibility, ease of use, ease of deployment, and increased security, SD-WAN is the answer you’re looking for.
