Stateful applications with Kubernetes

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

Kubernetes Service Mesh: A Comparison of Istio, Linkerd, and Consul

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

Kubernetes Security: What (and What Not) to Expect

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

Kubernetes Multi-Tenancy Best Practices

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

SELinux, Kubernetes RBAC, and Shipping Security Policies for On-prem Applications

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
