Our CTO Andy Jeffries explains how k3s by Rancher Labs differs from regular Kubernetes (k8s). Since we launched the world’s first k3s powered, managed Kubernetes service – we’ve had a lot of questions from our members on what the differences are between k3s and k8s (full blown Kubernetes), aside from the choice from each on how to capitalise a "K" (or not).

Maintaining reliable Kubernetes systems is not easy for anyone, especially for team members with less in-depth knowledge of Kubernetes itself and the overall service environment. This blog, part 1 of 3 in the “8 SRE Best Practices to Help Developers Troubleshoot Kubernetes” series, outlines the key challenges SREs and developers face when they need to quickly troubleshoot and remediate issues in applications running on Kubernetes.

Rajeev Kumar, Automation Product Leader at Broadcom, explores the 2023 Gartner® Market Guide for Service Orchestration and Automation Platforms. He reveals how Automation from Broadcom embraces the concepts of SOAP, driving a modern workload automation strategy.

Rancher is a Kubernetes management platform that creates a consistent environment for multicloud container operation. It solves several of the challenges around multicloud Kubernetes deployments, such as poor visibility into where workloads are running and the lack of centralized authentication and access control. Multicloud improves resiliency by letting you distribute applications across providers.

In this post we want to give a simple introduction for using network policies in a sample project and explaining how it works in K3s to help improving the security of your deployments. There is a common misunderstanding about K3s support for network policies, as K3s is using flannel CNI by default, and the Flannel CNI doesn’t support network polices.

Google Cloud provides its own set of metrics for monitoring applications, services, and instances. There are a huge number of metrics – more than 1,500 different ones just for GCP monitoring! While this is great, dealing with such a number can also be overwhelming. Filtering, pulling, exploring, and storing the metrics that you really need can be an enormously time-consuming task, and a big challenge.

The arrival of Docker container technology brought with it an amazing array of capabilities. By encapsulating an entire software package, including its dependencies and libraries, into a single, portable container, Docker has made deployment across platforms such as AWS, Google Cloud, Microsoft Azure, and Apache a simple and straightforward process. When people talk about Docker, they probably talk about Docker Engine, the runtime that allows you to build and run containers.

The world of DevOps is constantly evolving and adapting to the needs of the software development industry. With the increasing demand for faster and more efficient software delivery, organizations are turning to modern technologies and practices to help them meet these challenges. In a series of articles on the Kublr blog, we will take a look at some of today’s top DevOps trends.

What is the difference with similar tools? Detect graftcp with Falco Conclusion A new network open source tool called graftcp (GitHub page) has been discovered in everyday attacks by the Sysdig Threat Research Team (TRT). Nowadays, threat actors try to improve their techniques by using new tools (as we mentioned in the PRoot article) to enhance the compatibility of their code to hit as many targets as possible and hide their traces properly.

Cloud technology is growing rapidly, and we see a new cloud service almost every day. Deploying your product releases rapidly and efficiently is crucial for any business. AWS, being the market leader in the cloud world, has a lot of tools and services which facilitate deployments. Last year, we discussed different deployment options on AWS. Now that AWS has launched some new features, we will present the 2023 version of our previous article on the best AWS deployment options in 2022.
