Dickerson's Hierarchy of Service Reliability

From Wikipedia: “Abraham Maslow was an American psychologist who was best known for creating Maslow’s hierarchy of needs, a theory of psychological health predicated on fulfilling innate human needs in priority…” In developmental psychology, Maslow’s hierarchy is a classification system that reflects the universal needs of society as its base and then proceeds to more acquired emotions. Here is a graphical depiction of Maslow’s hierarchy.

3 Steps to Full-Stack Awareness With Nutanix

If you’ve chosen Nutanix Enterprise Cloud, you’re almost certainly relying on Nutanix Prism to help you migrate, then operate, the “enterprise cloud.” There’s no doubt that Prism is an outstanding tool for managing virtual environments. But — when was the last time someone complimented you on a well-managed virtual environment. Never, right? Because that’s not your job.

Kubernetes vs Docker Swarm: Comparison of Two Container Orchestration Tools

With the rise of the containerization technology and increased attention from enterprises and technologists in general, more and more containerized applications have been deployed to the cloud. Moreover, research conducted by 451 Research predicts that the application container market will grow dramatically through 2020, which will continue to expand the number of containerized applications being deployed to the cloud.

Runc CVE-2019-5736

Today CVE-2019-5736 was announced which impacts all known versions of runc. Runc is the underlying component that creates containers in Docker, Kubernetes, and many other container systems. The full details of this vulnerability are available in the Openwall oss-security mailing. Due to the severity of this issue, exploits will not be published for another week, giving people time to patch.

Optimizing Cloud Cost Using Cloud Lease

“I want to optimize cloud costs, my monthly bills are running high and we are overshooting our budgets, I thought by migrating to cloud we would end up saving!” Heard that before? This is the basic question from the senior management as to how can we lower the high-infrastructure cost once on the cloud. If you are facing either or all the challenges below, this article is for you!

The Anatomy of a Serverless App

Serverless has, for the last year or so, felt like an easy term to define: code run in a highly managed environment with (almost) no configuration of the underlying computer layer done by your team. Fair enough, but what is is a serverless application? A Lambda isn’t an app by itself, heck, it can’t even communicate with the world outside of Amazon Web Services (AWS) by itself, so there must be more to a serverless app than that.

Achieving Full Stack Automation Through Kubernetes

The open source revolution is back in full swing with the rise of Kubernetes. Flexibility and agility are the key factors to making the most of the cloud, multicloud, or hybrid cloud era. Kubernetes makes that easier by granting DevOps teams greater control across their infrastructure. But easier does not necessarily mean easy — there are still hurdles to overcome.

A Beginner's Guide to Getting Started with Google Kubernetes Engine (GKE)

There’s no shortage of providers willing to host your containers. Many of the world’s biggest cloud platforms offer Kubernetes as a service, including features such as automatic scalability and high availability. However, Google Cloud Platform (GCP) stands out as perhaps the best tool for building and hosting a Kubernetes cluster for a number of reasons. In this article, we’ll present these reasons and why GCP offers a better Kubernetes experience than other providers.
