Istio vs. Linkerd vs. Envoy: A Comparison of Service Meshes

In a previous article, we examined service meshes in detail. Briefly, a service mesh takes care of network functionality for the applications running on your platform. As Kubernetes has matured as a technology, service meshes have become a hot topic, with various products being developed to solve the challenges associated with areas like traffic management, security, and observability. This article will compare three service meshes.

How to monitor Kubernetes audit logs

Datadog operates large-scale Kubernetes clusters in production across multiple clouds. Along the way, audit logs have been extremely helpful for tracking user interactions with the API server, debugging issues, and getting clarity into our workloads. In this post, we’ll show you how to leverage the power of Kubernetes audit logs to get deep insight into your clusters.

Kubernetes Events Explained

Kubernetes events are a resource type in Kubernetes that are automatically created when other resources have state changes, errors, or other messages that should be broadcast to the system. While there is not a lot of documentation available for events, they are an invaluable resource when debugging issues in your Kubernetes cluster. In this post we will learn how to look at events, learn about a few specific event types, and discuss how to monitor Kubernetes events.

Supercharging Workload Security in Your K8s Cluster

2019 was a big year for Kubernetes adoption, and 2020 is sure to exceed that pace. Already, we have seen a large number of organizations migrating their workloads to Kubernetes (k8s) both in public and private clouds as they embrace a hybrid cloud strategy. With so much at stake, what are you currently using for network security inside your k8s cluster?

What is Autodiscover for Filebeat? And why do we need it?

Microservices constantly change in containerized environs, making pod or node identification and their logging more of a challenge. Autodiscover simplifies monitoring movements in these sorts of environments—places like Kubernetes and Docker. Autodiscover allows you to track pods and adapt settings as changes happen in your environment.

Transport Layer Security Termination In Rancher 2.x, Part Two

In this blog series, we’ll explore a few ways that Rancher uses of TLS certificates. TLS, or Transport Layer Security, is a cryptographic protocol used to secure network communication. It is the successor to the now-deprecated Secure Sockets Layer, or SSL. You can expect to walk away with an understanding of how TLS integrates into various Rancher components, and how you can prepare your environment to properly leverage TLS in Rancher.

Make Kubernetes Essential to Your DevOps Pipeline

Kubernetes has seen an incredible rise over the past few years as organizations leverage containers for complex applications, micro-services and even cloud-native applications. And with the rise of Kubernetes, DevOps has gained more traction. While they may seem very different — one is a tool and the other is a methodology — they work together to help organizations deliver fast. This article explains why Kubernetes is essential to your DevOps strategy.

Monitoring a multi-cluster environment using Prometheus federation and Grafana

Monitoring the state of your clusters is an effective way to discover bottlenecks in your multi-cluster production environment. It is one of the key challenges that development teams are facing and factors such as the team experience as well as the number and distribution of the applications can make things even more complex. Better monitoring can help identify single points of failure.
