As the cloud-native ecosystem continues to evolve, many alternative solutions are popping-up, that challenges the status quo of application deployment methodologies. One of these solutions that is quickly gaining traction is Unikernels, which are executable images that can run natively on a hypervisor without the need for a separate operating system.

It’s only four months ago that I blogged about histograms in Prometheus. Back then, I teased my talk planned for (virtual) KubeCon Europe 2020. On Aug. 20, the talk finally happened.

Logs in continuous delivery pipelines are often entirely ignored, right up until something goes wrong. We usually find ourselves wishing we’d put some thought into our logs, once we’re in the midst of trawling through thousands of lines.

A growing movement of businesses, including performance monitoring services like Request Metrics, are working to create sustainable web analytics tools. Tools that give web developers the metrics they need to improve their websites without compromising the privacy of our users.

Nowadays, software development teams utilize continuous delivery or some variation, to create better, faster, more accurate software releases. Continuous delivery is a DevOps practice that empowers software teams to continuously ship code directly to an environment once automated tests pass. Continuous delivery is facilitated through the deployment pipeline. You can read more about it in a previous post.

With the state of the world today, healthcare facilities of all kinds and sizes are operating under a state of distress. Employees are working on the frontlines, while also having to manage low budgets for IT security, coupled with low resources and all the while having to manage legal and compliance issues on top of it.
