Multi-Cluster Application Network (MCAN)

What is a MCAN?

The easiest way to visualize, connect, secure, protect, and monitor microservices communication across any cluster, site, cloud, or network. A Multi-Cluster Application Network is an overlay network that connects to multiple Kubernetes Clusters, so that pods and services can communicate securely between clusters.  

What is Skupper?

powered-by-redhat logo

Skupper an open source project created by RedHat.  It's a containerized layer 7 router that you can put in a K8s cluster to build a Multi-Cluster Application Network.  Pods can communicate securely across Kubernetes clusters with no VPNs or special firewall rules. With Skupper, your application can span multiple cloud providers, data centers, and regions.


Nethopper uses Skupper to securely connect your KAOps tools, clusters, and applications.  For example, when ArgoCD attaches a remote cluster, it must connect to remote cluster's K8s API service.  Most people expose the K8s API to the internet, and that’s risky. We use skupper to securely attach remote clusters without exposing the K8s API.  For another example, if you want to connect your frontend running in one cluster, to your backend database running in a different cluster, we use skupper to do it.

MCAN as a Service

Simplify Your Kubernetes Communications

Microservice and contains need to communicate for your app to work.  Often, between two or more clusters.  There’s two ways to make that communication; the hard way, and the easy way.  Too many DevOps teams do it the hard way.  First, they hire a team to implement a service mesh with sidecars.  Then, to get in and out of Kubernetes clusters, they hire a team to implement an ingress gateway.  Then, to get in and out of the cloud networks, they hire a team to automate network configuration (firewalls, gateway routers, load balancers).  In the end, they have 3 teams, each with their own dashboards in each cloud.  

The easy way is to use Nethopper MCAN.  Simply sign up, and even with no training, you can easily discover and connect your containers in multiple clouds.  It only takes a few minutes.
