How to debug Kubernetes Pending pods and scheduling failures

When Kubernetes launches and schedules workloads in your cluster, such as during an update or scaling event, you can expect to see short-lived spikes in the number of Pending pods. As long as your cluster has sufficient resources, Pending pods usually transition to Running status on their own as the Kubernetes scheduler assigns them to suitable nodes. However, in some scenarios, Pending pods will fail to get scheduled until you fix the underlying problem.

Create powerful data visualizations with the new Datadog dashboards experience

Dashboards are a crucial tool in your monitoring arsenal, as they allow you to visualize and correlate telemetry data from across your stack in a single place. Historically, Datadog offered two dashboard types: Screenboards, for pixel-level control on a canvas, and Timeboards, for troubleshooting a specific point in time. Now, we’re excited to introduce a new dashboard layout that combines the best of Timeboards and Screenboards in a single, seamless editing experience.

Data Lake, Data Lab, Data Hub: what's the difference?

In this post we’ll explore the concepts of data lake, data hub and data lab. There are many opinions and interpretations of these concepts, and they are broadly comparable. In fact, many might say they’re synonymous and we’re just splitting hairs. But let’s look again carefully.

Careful attention to database query construction and execution also pays similar dividends, as improved database performance helps organizations get more done faster.

Integrating a Cloudsmith repository with a Semaphore CI workflow

At Cloudsmith, we believe that packaging should be at the centre of any modern build and deployment process. In fact, we think that Continuous Packaging is the glue that ties Continuous Integration and Continuous Deployment or Delivery together. So with that in mind, in this blog, we will take a walk through how easy it is to integrate Cloudsmith with a Semaphore CI workflow and push the artifacts and packages that you build to a private repository. TL:DR – It’s super easy.

A DBA's Habit for Success: CMMI (Part Two)
