Due to the surge in remote work inspired by COVID-19, VPN infrastructure designed to support 10-20% of the workforce has failed to keep up. This has inspired companies to invest in scaling their VPN infrastructure, but this is not as easy as it sounds. All systems (VPN, networking, security, etc.)

A recent conversation with a WAN engineer got me thinking about how network optimization techniques have changed over the years. Optimization has always been about overcoming latency, jitter, packet loss, and bandwidth limitations. However, in recent years bandwidth has become much less of an issue for most enterprises.

This stat struck a chord with me as it helps to quantify a common problem the Cato team works with customers to solve: reducing WAN latency. However, keeping WAN latency in check while using traditional solutions, like MPLS or VPN, with cloud services has become impractical. Well answer that here.

Nick Dell is an IT manager who recently led a network transformation initiative at his company, moving from MPLS to SD-WAN. Dell shared why he made that transition and the lessons he learned along the way in the webinar SD-WAN Confessions: How I migrated from MPLS to SD-WAN. I couldnt trust them to manage the SD-WAN, says Dell.

Software-Defined Wide Area Networks (SD-WANs) promised to address the high costs, rigidity and limitations of private MPLS services. Like so many technologies, though, there are the promises of SD-WANs and then there are the realities of SD-WANs. Bandwidth upgrades and changes can also take weeks.

The Dutch engineering company had built a global wide area network (WAN) out of MPLS and Internet services connecting 17 locations 14 in Europe and 3 in the Asia Pacific with about 800 mobile and field employees. Cloud applications were starved for bandwidth as they were backhauled across a 10 Mbits/s connection to the datacenter.

The market for SD-WAN has been driven in part by its ability to reduce bandwidth costs and improve the performance of cloud access.
