In this blog post, we’ll introduce you to WebAssembly. We’ll start with a history lesson on the Assembly language, which was created to make programming easier and boost productivity. Then we’ll move on to WebAssemby, a descendent of Assembly, and cover what it is, the problems it solves and how it does that. Assembly Decades ago, if you wanted to program a computer, you had to write binary code. We called it machine code because it is the native language of any computer (maybe this will change with the rise of quantum computing, but for now, every computer works on binary code ..read more

Virtual machines (VMs) have transformed infrastructure deployment and management. VMs are so ubiquitous that I can’t think of a single instance where I deployed production code to a bare metal server in my many years as a professional software engineer. VMs provide secure, isolated environments hosting your choice of operating system while sharing the resources of the underlying server. This allows resources to be allocated more efficiently, reducing the cost of over-provisioned hardware ..read more

In Episode 1 of the OCTOpod, Alan Clark talks with Thierry Carrez about open source communities: what they are, how they work and how you can get involved. Trying to define what an open source community is might sound like a simple task, but it is a layered, nuanced collective with many moving parts. Thierry has been in the open source community for years and is currently the VP of engineering at the Open Infrastructure Foundation ..read more

Building successful machine learning (ML) production systems requires a specialized re-interpretation of the traditional DevOps culture and methodologies. MLOps, short for machine learning operations, is a relatively new engineering discipline and a set of practices meant to improve the collaboration and communication between the various roles and teams that together manage the end-to-end lifecycle of machine learning projects. Helping enterprises adapt and succeed with open source is one of SUSE’s key strengths ..read more

We are happy to share the v0.3.0 release of Rancher Desktop. This release brings more stability, some new features, and a fresh look to the UI. This screenshot shows the preferences screen while in dark mode on Mac. In the lower left corner the status when performing an action is now displayed. This status will tell you when Rancher Desktop needs to download something, such as a version of Kubernetes you have now used before, or when another step is happening ..read more

For those of us who need to get applications running in Kubernetes, having Kubernetes on the desktop is incredibly useful. When we want to focus on our applications, it’s especially useful when Kubernetes is easy to use. This is where Rancher Desktop comes in. Rancher Desktop provides easy-to-use Kubernetes and container management (something we’ll look at in a moment) for Mac and Windows. Having Kubernetes isn’t enough. Being able to choose your version of Kubernetes and even being able to test upgrading Kubernetes versions is important ..read more

It has been five months since we announced project Harvester, open source hyperconverged infrastructure (HCI) software built using Kubernetes. Since then, we’ve received a lot of feedback from the early adopters. This feedback has encouraged us and helped in shaping Harvester’s roadmap. Today, I am excited to announce the Harvester v0.2.0 release, along with the Beta availability of the project! Let’s take a look at what’s new in Harvester v0 ..read more

Containers and Kubernetes have changed the way we operate applications. This has been a boon for Site Reliability Engineers (SREs) and DevOps professionals who handle infrastructure management. Yet, it has come at a cost to many who develop and operate applications. Their experience has become more complicated and cumbersome. If we look at our cloud or cluster computing platforms as a stack, Kubernetes and many supporting tools have focused on low-level concerns ..read more

Whether you’re new to the cloud native space or an accomplished practitioner, you’re probably aware that there are many Kubernetes distributions to choose from. Maybe you’ve heard about the challenges of getting up and running with Kubernetes. Guess what? It doesn’t have to be hard. This blog provides an introduction to K3s, a lightweight CNCF-certified Kubernetes distribution. We’ll look at what makes K3s different from other Kubernetes distributions. Built for resource-constrained environments like network edge devices, K3s is lightweight and simple yet ready for production from day one ..read more

Security has always been a wide and complex topic. A recent survey from StackRox about the state of containers and Kubernetes security provides some interesting data on these topics. In this blog post, I’ll dive into some of the findings in that survey and introduce you to Kubewarden, an open source policy engine. Security Measures and Skills are Lacking A staggering 66 percent of the survey participants do not feel confident enough in the security measures they have in place ..read more
