When containers became mainstream, they were designed to support ephemeral – stateless – workloads. Since then, a lot of effort has been made to support stateful applications in the container ecosystem, with a lot of that focus targeted towards better support from core Kubernetes. Stateful applications – and the data they contain – are extremely […]

We just returned from KubeCon + CloudNativeCon 2019 held in sunny San Diego Nov 18-21. KubeCon San Diego 2019 drew more than 12,000 attendees, a 50% increase since the last event in Barcelona, just 6 months ago. While at the event, we interacted with more than 1,800 attendees and had more than 1,300 attendees complete

Machine Learning (ML) is rapidly becoming essential to businesses and institutions across the globe. Each organization must meet the challenge of provisioning a computational infrastructure that can support a resource-intensive machine-learning pipeline. While moving computation to the cloud has become the standard response to the challenge of scalability, machine learning teams have specific needs that

Cloud-native applications are often architected as a constellation of distributed microservices, which are running in Containers. Increasingly, these containerized applications are Kubernetes-based, as it has become the de-facto standard for container orchestration. One outcome that most companies using microservices architecture don’t fully understand the impact of until they are well down the path is microservices

When it comes to security, there is a lot that Kubernetes does. There is also a lot that it doesn’t do. To secure Kubernetes effectively for real-world deployment, you must understand which built-in security features Kubernetes offers and which it doesn’t, and how to leverage Kubernetes’s security capabilities at scale. Below, we walk through Kubernetes’s

Overview This article will cover: What Is Kubernetes Service Discovery Deploy an Application as a Pod Create A Kubernetes Service Service Discovery Troubleshooting What Is Kubernetes Service Discovery One of the reasons why Kubernetes is the leading Container Orchestration platform today is because it offers a nice separation of concerns in terms of describing workloads. Essentially,

In a simpler world, all Kubernetes deployments would host just a single tenant — meaning only one workload or application runs on the entire Kubernetes environment. In the real world, it’s common to have multi-tenant Kubernetes deployments. In a multi-tenant deployment, multiple workloads share the same underlying Kubernetes infrastructure. Multi-tenant Kubernetes creates some special challenges

Overview This article will cover: Kubernetes Upgrade Paths Upgrading Kubernetes: A Step-by-Step Guide Etcd Upgrade Paths Upgrading etcd Operating enterprise Kubernetes deployment is difficult. That is due in no small part to the fact that Kubernetes is not just one tool, but a collection of a dozen-odd components that provide functionality ranging from application deployments

Earlier today we had the pleasure of presenting at a CNCF-hosted webinar about KubeVirt. KubeVirt is a set of Kubernetes CRDs and controllers (an Operator) that lets you run virtual machines on Kubernetes! In this webinar we discussed: Introduction of KubeVirt, its concepts and architecture Key use cases where you can already take advantage of

At VMworld 2019, VMware shared two major announcements: VMware Tanzu Mission Control, which provides multi-cluster management across distributed Kubernetes clusters and Project Pacific, which ties Kubernetes more closely within vSphere. These are significant announcements in the first VMworld following VMware’s acquisition of Heptio a year ago and the recent news of its intent to purchase

Security-Enhanced Linux (SELinux) is a swiss army knife for Linux security, which is as relevant in commodity Kubernetes deployments as it was in yesterdays era of artisanally crafted linux server silos. Whether or not you are using cloud native technology, some of the lessons we’ve learned around being transparent, disciplined in your security practices, and

Kubernetes orchestrates containers reliably at scale while abstracting the underlying infrastructure. Unlike Virtual Machines, this helps developers separate the workloads from the complexities of the infrastructure. Kubernetes is ideal for CI/CD automation because it offers many built-in capabilities that makes application deployment standardized and reusable, improves developer productivity, and speeds up the adoption of cloud-native
