What is an overlay network?

An Overlay is a tunnel providing connectivity over the physical infrastructure. IPsec is an example of this.

Does the MCNA apply to k8s workloads as well?

All the examples presented were based on VMs workloads but it applies to k8s workloads as well.  They would reside in a VPC at the end of the day, so we can handle it.

Is the MCNA an open framework? If so, who is contributing to it?

The MCNA is an architecture that Aviatrix developed and implements using our platform. Others may leverage this type of architecture in the future as it is cloud-agnostic. We believe this is the best reference architecture for the cloud for single cloud or multi-cloud deployments.

If we are using the same subnet in a different VPC, how does MCNA address that?

Aviatrix provides the ability to overcome overlapping CIDRs if you’re using them repeatedly. If you are referring to IP address overlap, we have some solutions for that. The gateways we can deploy can provide SNAT/DNAT functionality but this use case is discussed in depth in our Professional course.

What encryption does Aviatrix use?

Aviatrix is FIPS 140-2 certified for Level 1. See our certificate at:

How many paths are being built between multi-clouds and how does Aviatrix handle path degradation (packet loss, latency, jitter, etc.)?

Aviatrix Gateways are deployed in ActiveMesh mode basically Avtive/Active criss-cross links, with built-in high availability. One can build as little as one path or higher depending on the requirement. We recommend our customers to use private circuits such as DX or Express Route to build the cloud-to-cloud connectivity which can mitigate the issues that comes with public Internet facing links.
