Kentik Blog: WAN and SD-WAN

SD-WAN is a reliable, fast, and secure WAN network. In this guide, you’ll learn some best practices for planning, monitoring, analyzing, and managing modern SD-WANs.

Today’s modern enterprise WAN is a mix of public internet, cloud provider networks, SD-WAN overlays, containers, and CASBs. This means that as we develop a network visibility strategy, we must go where no engineer has gone before to meet the needs of how applications are delivered today.

Today’s enterprise WAN isn’t what it used to be. These days, a conversation about the WAN is a conversation about cloud connectivity. SD-WAN and the latest network overlays are less about big iron and branch-to-branch connectivity, and more about getting you access to your resources in the cloud. Read Phil’s thoughts about what brought us here.

The advent of various network abstractions has meant many day-to-day networking tasks normally done by network engineers are now done by other teams. What’s left for many networking experts is the remaining high-level design and troubleshooting. In this post, Phil Gervasi unpacks why this change is happening and what it means for network engineers.

SD-WAN promises to boost agility, security, performance, and management and operations. However, without effective network visibility, the path to a successful deployment is difficult to achieve. In this post, we provide considerations for solving SD-WAN visibility challenges.

Google is investing and innovating in SD-WAN. In this post, Kentik CTO Jonah Kowall highlights what Google has been up to and how Google’s SD-WAN work can apply to the typical organization.

Fixing a persistent Internet underlay problem might be as simple as using a higher bandwidth connection or as complex as choosing the right peering and transit networks for specific applications and destination cloud services. In this blog, ACG analyst Stephen Collins advices that to make the best-informed decision about how to proceed, IT managers need to be equipped with tools that enable them to fully diagnose the nature of Internet underlay connectivity problems.

As one of 2017’s hottest networking technologies, SD-WAN is generating a lot of buzz, including at last week’s Cisco Live. But as enterprises rely on SD-WAN to enable Internet-connected services — thereby bypassing Carrier MPLS charges — they face unfamiliar challenges related to the security and availability of remote sites. In this post we take a look at these new threats and how Kentik Detect helps protect against and respond to attacks.
