DevOps Toolchain Explained: What Is & How to Create One. Choosing Between Buying or Building Your Own Tools

Over the past few years, we’ve seen an almost obsession with developing and adopting CI/CD tools throughout the DevOps community. There are thousands of “how-to’s”, “top x tools”, and “tool x vs tool y” type articles, and it has gotten to the point where it’s quite difficult to figure out how and which one to pick as your own.

Implementing Canary Releases on Kubernetes with Spinnaker, Istio, and Prometheus

In a microservices world, applications consist of dozens, hundreds, or even thousands of components. Manually deploying and verifying deployment quality in production is virtually impossible. Kubernetes, which natively supports rolling updates, enables blue-green application deployments with Spinnaker. However, the gradual rollout is a feature that doesn’t come out-of-the-box but can be achieved by adding Istio and Prometheus to the equation.

The Fastest at the Edge

When you think of Kubernetes, you probably don't think "fast," but that's what K3s has at its core. Designed for resource-constrained environments like IoT and the Edge, K3s is lightning fast, robust, and powerful, and it includes innovative new features like its Helm controller. In this short video, Adrian Goins talks about K3s, MetalLB, Nginx, Traefik, and Helm while doing an install of a K3s system with MetalLB, Nginx, and Mosquitto in only a few minutes.

Deploy HAProxy Ingress Controller from Rancher's Apps Catalog

In Kubernetes, Ingress objects define rules for how to route a client’s request to a specific service running inside your cluster. These rules can take into account the unique aspects of an incoming HTTP message, including its Host header and the URL path, allowing you to send traffic to one service or another using data discovered in the request itself. That means you can use Ingress objects to define routing for many different applications.

Elastic Security opens public detection rules repo

At Elastic, we believe in the power of open source and understand the importance of community. By putting the community first, we ensure that we create the best possible product for our users. With Elastic Security, two of our core objectives are to stop threats at scale and arm every analyst. Today, we’re opening up a new GitHub repository, elastic/detection-rules, to work alongside the security community, stopping threats at a greater scale.

Continuous Intelligence for Atlassian tools and the DevSecOps Lifecycle (Part 2)

Today’s modern deployment pipeline is arguably one of the most important aspects of an organization’s infrastructure. The ability to take source code and turn it into a production application that’s scalable, reliable and highly available has become an enormous undertaking due to the pervasiveness of modern application architectures, multi- or hybrid-cloud deployment strategies, container orchestration and the leftward movement of security into the pipeline.

Dissecting a Tanzu Kubernetes Cluster Spec with the TKG Service for vSphere

This post is part of a series that examines some of the fundamentals of creating, utilizing, and managing Tanzu Kubernetes clusters with the Tanzu Kubernetes Grid (TKG) Service for vSphere. If you need a primer to understand the basic concepts, make sure you read vSphere 7 — Introduction to Tanzu Kubernetes Grid Clusters. And if you haven’t already, this would also be a good time to read An Elevated View of the Tanzu Kubernetes Grid Service Architecture, the first post in the series.

How SLIs Help You Understand Users' Needs

In our article on SLOs, we discussed the need for service level indicators to be relevant to the users’ experience. By consolidating a number of internal metrics into one indicator that reflects the typical use of the service, we can ensure that meeting our SLO means keeping users happy. A good way to think about this is by looking at the user’s experience or journey.
