Service Mesh Comparison: Istio vs. Linkerd

As service architectures have transitioned from the monolith to microservices, one of the tougher problems that organizations have had to solve is service discovery and load balancing. The advent of service mesh technologies seeks to solve these and other problems exacerbated by the number of hosts that has grown exponentially. In this article, we’re going to explore what a service mesh is.

How to Troubleshoot Microservice Connectivity in Kubernetes

In this online training we will demonstrate how to troubleshoot and resolve service-to-service connectivity issues for microservices running on Kubernetes. We will show how to do this manually using system logs as well as features in Calico Enterprise that simplify troubleshooting.

How to pronounce Kubernetes so you don't get laughed at

We’ve all been there. A new tool is trending, it is getting mentioned all over the place, and you get dropped into a conversation about it. The last thing you want to do is embarrass yourself by pronouncing something wrong and revealing you don’t know anything about the latest thing. We want to make sure you avoid that happening. When it comes to Kubernetes, there are really only four terms that you might need some help with pronouncing.

How to find-and use-your GKE logs with Cloud Logging

Logs are an important part of troubleshooting and it’s critical to have them when you need them. When it comes to logging, Google Kubernetes Engine (GKE) is integrated with Google Cloud’s Logging service. But perhaps you’ve never investigated your GKE logs, or Cloud Logging? Here’s an overview of how logging works in GKE, and how to configure, find, and interact effectively with the GKE logs stored in Cloud Logging.

Longhorn: Rancher's Journey from Zero to GA

When Frodo was commissioned on a seemingly straightforward journey to retrieve the One Ring, I doubt he realized the adventure and commitment he was embarking on. Rancher Labs started on a similarly daring journey almost four years ago. It didn’t take a wizard showing up uninvited at dinner to convince us of this. From the beginning of Rancher Labs, our founding team had a deep conviction about the importance of storage in the future of cloud-first computing.

Longhorn Simplifies Distributed Block Storage in Kubernetes

Today we’re announcing the general availability of Longhorn, an enterprise-grade, cloud-native container storage solution. Longhorn directly answers the need for an enterprise-grade, vendor-neutral persistent storage solution that supports the easy development of stateful applications within Kubernetes. We’ve been working on Longhorn for almost as long as we’ve been around as a company.

Datadog on Kubernetes

When 2 years ago Datadog decided to move its infrastructure platform to Kubernetes we didn’t expect to find so many roadblocks, but ingesting trillions of datapoints per day in a reliable fashion requires pushing the limits of cloud computing. Creating and managing dozens of clusters, with thousands of nodes each and operating in several clouds was a challenging but rewarding learning experience. In this episode Ara Pulido, Developer Advocate, will chat with Laurent Bernaille, Staff Engineer at Datadog and part of the team that created Datadog’s Kubernetes platform. We’ll cover the challenges we found creating and scaling Datadog’s Kubernetes platform and how we overcame them.

KMC - Running a Multi-Cluster Service Mesh in Rancher

If you are or your organization is running Kubernetes, then it's likely that you are running more than one cluster. This model works well for most, but starts to break down when microservices and service mesh enter the discussion. However, with some additional configuration and tooling , a multicluster mesh can take advantage of distributed Kubernetes environments and the services therein. In this Master Class, recorded on June 20, 2020, Rancher Field Engineer Jason Skrzypek discusses and demos a multi-cluster service mesh running Istio.
