Right now, we have the building blocks for network automation, but we don’t have end-to-end designs or complete systems. It’s like having a bunch of Legos but no instructions for how to build your spaceship. Ryan Shaw, David Sinn, and their colleagues in the Network Automation Forum are tackling this problem. Their goal is to... Read more »

Kubernetes is designed to be highly scalable and highly dynamic… a perfect habitat for cryptominers to terminal shell into and then exploit your workload’s resources to the max.

One dark day, Ivan Pepelnjak stopped labbing. He just couldn’t make himself yet again go through assigning addresses, building links, putting devices in place, setting up OSPF, BGP, VXLAN, EVPN, etc. before even being able to start whatever simulation or test he wanted to do. But from that darkness arose netlab. Ivan created netlab to... Read more »

It’s rare for strategists, executives, and technologists to all get on the same page in order to create, execute, and adjust an organization’s tech strategy, much less do it well. But it is possible.

What are we talking about when we are all talking about private clouds? On-prem? Hybrid? Virtualization? Where does hardware fit into it all– and would younger engineers even know what to do with a physical piece of hardware? Driven by Broadcom’s acquisition of VMare and the anticipated rising costs of VMare licenses, enterprises are exploring... Read more »
