SD-WAN, SASE, and NaaS: Understanding Underlay vs. Overlay Networking

By 2024, Gartner predicts that enterprises will be spending a whopping $516B on cloud services. With 93% of enterprises reporting that they have a hybrid or multi-cloud strategy, getting cloud connectivity right is a must.

But there are a lot of similar-sounding propositions and confusing terminology on how you should connect to and within your cloud instances.

In this webinar, we’ll help you understand the differences between and the use cases for various approaches to overlay and underlay networking, including:

  • Cloud networking VPN overlays
  • SD-WANs and SASE
  • AWS Direct Connect, Azure ExpressRoute, Google Partner Interconnect and related private cloud network services
  • Underlay networks from MPLS to Network as a Service
