One of the hands-on exercises in our Networking in Public Cloud Deployments online course asks the attendees to deploy a full-blown virtual networking solution with a front-end (web) server in a public subnet, and back-end (database) server in a private subnet.
The next (optional) exercise asks them to add IPv6 to the mix for a full-blown dual-stack deployment.
Packet duplication wastes bandwidth and can lead to significant network performance degradation or even outages.
In multicast routing, packets are replicated by the network, so there is always a fundamental risk of duplicate traffic. Special safeguards exist to avoid …
50 years ago when the first Earth Day happened, the networks that would later form the Internet were only beginning.
20 years later, when Earth Day 1990 turned the celebration into a global event, the World-Wide Web existed only as a single website in Switzerland.
Today, the Internet is our lifeline. In a world locked down by coronavirus, the Internet is how we connect. It is how we communicate, collaborate, and create together. It is how we work and how we play. And on this Earth Day 2020, we will use the Internet to celebrate the 50th anniversary.
Each and every day, we are using the Internet to respond to climate change and other environmental issues:

When IBM announced that it was acquiring Red Hat for $34 billion eighteen months ago, one of the things we said that Big Blue needed most and would get from taking over – but not messing with – the world’s largest commercial open source software company was a coherent story that it could tell to its customers about how IBM, which more than any other company helped define data processing, was still relevant to the future. …

Designing and maintaining networks is hard. When deploying Kubernetes in your on-prem data center, you will need to answer a basic question: Should it be an overlay network on top of an existing network, or should it be part of an existing network? The Networking options table provides guidelines to choose the right type of networking based on various factors. If you decide to use native peering (pre-dominant option for on-prem), you will have to configure the network to ensure availability in the event of network outage (ex. Cable disconnected, TOR switch failure etc.). We cover a typical L3 highly-available network design in this post.
A cluster spans multiple racks. In an L3 deployment, these racks have different CIDR ranges. So the nodes in different racks should be able to talk to each other. Referring to the diagram below, that traffic goes through the network fabric. If you want to build out such a lab for your own learning, here is the example.
If you have a leaf-spine fabric with a single TOR (top-of-rack, or leaf switch), then that TOR becomes a point of failure for the entire rack. If all the master nodes are on the same Continue reading
