3 Trends in test automation

Automation is becoming a powerful tool in every industry. With the pace of development at breakneck speed, test automation is a big asset in deploying applications quickly. The volume and complexity of testing environments mean that machines are well-suited for the job, and a modern QA strategy is all about leveraging that automation effectively.

Python at Netflix

As many of us prepare to go to PyCon, we wanted to share a sampling of how Python is used at Netflix. We use Python through the full content lifecycle, from deciding which content to fund all the way to operating the CDN that serves the final video to 148 million members. We use and contribute to many open-source Python packages, some of which are mentioned below.

Cilium 1.5: Scaling to 5k nodes and 100k pods, BPF-based SNAT, and Rolling Key Updates for Transparent Encryption

Linkerd or Istio?

This week I set out to write a post comparing Istio and Linkerd, and I told myself: I’m going to create tables comparing features, and it’s going to be great and people will love and the world will be happier for a few seconds. I promised myself It was going to be a fair comparison without bias from any end. While the ‘comparison table’ is still here, I shifted the focus of the article: the goal is not on which is better, but which is better for you, for your applications, for your organization.

Guidance for Building a Control Plane for Envoy Part 5: Deployment Tradeoffs

Setting up Kubernetes Network Policies

The container orchestrator war is over, and Kubernetes has won. With companies large and small rapidly adopting the platform, security has emerged as an important concern — partly because of the learning curve inherent in understanding any new infrastructure, and partly because of recently announced vulnerabilities. Kubernetes brings another security dynamic to the table — its defaults are geared towards making it easy for users to get up and running quickly, as well as being backward compatible with earlier releases of Kubernetes that lacked important security features.

Debugging Istio control plane with Squash

Solo.io Squash is a distributed debugger that supports multiple languages. When running in a container environment like Kubernetes, debugging applications can be difficult especially when distributed into multiple containers with implementations in potentially different languages. Istio is a service-mesh implementation that exemplifies this “microservice” architecture by implementing its control plane as a set of services.

Introducing kube-iptables-tailer: Better Networking Visibility in Kubernetes Clusters

At Box, we use Kubernetes to empower our engineers to own the whole lifecycle of their microservices. When it comes to networking, our engineers use Tigera’s Project Calico to declaratively manage network policies for their apps running in our Kubernetes clusters. App owners define a Calico policy in order to enable their Pods to send/receive network traffic, which is instantiated as iptables rules.

Surface Kubernetes Errors with Sentry

Kubernetes, like a lot of other tools, can be noisy. Errors and warnings often go completely unnoticed in the event stream. Or sometimes they are noticed, but are hard to understand in the context of what else is happening in the cluster.
