Understanding the Complete Cloud Cost of Kubernetes

When organizations think about the relationship between Kubernetes and cloud costs, they often focus on Kubernetes’ auto-scaling capabilities and what this means for optimizing compute resources. Kubernetes does allow organizations to provision compute resources more thinly, because the platform allows them to scale up automatically if there’s a demand spike in the middle of the night.

All robots based on ROS and ROS 2 are programmed using five simple but core constructs: In this tutorial and associated video we’ll introduce these concepts with simulated robots.

Integrating Sensu Go into your CI/CD pipeline with sensuctl prune

Since the release of Sensu Go, many in our community have told us Sensu is easier and faster to deploy, more portable, and more compatible with containerized and ephemeral environments (as compared to Sensu Core, the original version of Sensu). In a recent webinar, I talked about integrating Sensu Go with your CI/CD pipeline and how to use the sensuctl prune command to keep your Sensu resources in a declarative state, reducing dependence on traditional configuration management tools.
