Sigh maybe I should use clunkier engineering at first and then “optimize” by just switching out to Polars ). I kid. Some data engineerer unintentionally do this, ensuring job security 😆 (some I am told do this intentionally - like insert some sleep(100) in a long loop, 🫤). Unfortunately it’s really hard to improve performance or reduce costs when Polars is your goto library for “T” layer of ETL.

Kubernetes turned 10 years old yesterday! I'm very glad I was able to participate in the after-work kubernetes meetup "KuberTENes Birthday Bash Munich" organized by Max Körbächer to celebrate this exceptional date! Next to a lot of cool stickers, a t-shirt raffle and "curry wurst" , I got the chance to meet some great engineers and learn more about Wasm and the inner workings of kubernetes sig (special interest groups). Mario Fahlandt with his talk "How works the infrastructure for the infrastructure? A view into Kubernetes’ inner workings." provided some great insights into the work of the kubernetes maintainers and I learned for example that registry.k8s.io is now hosted on AWS. He also provided some insights into their build organization around their Cicd tool " prow". For those curious ones, checkout https://lnkd.in/dEcp6fCu Also he shared an interesting anecdote: Last week the kubernetes X/Twitter account was suspended and they just got it unlocked again. The reason: They actually thought it's a nice idea to set the accounts birthday to the original kubernetes date of birth. Sadly X does not allow 10 year olds on their platform 😄 David Leitner with his talk "Containerless Kubernetes in a Multi-Cloud World" clearly pointed out the superiority of web assembly over containers in many area. Things I got out of this talk and the following discussions with attendees: - kcp: https://lnkd.in/dr7NyQaP a kubernetes variant for running wasm - https://wasmcloud.com/ a wasm orchestration layer worth having a look at Also some things i learned about WASM in later discussions: - small binaries: quick transfers, quick startup - security by default: everything the binary is allowed to do needs to be implemented and enabled first, quite an advantage in comparison to kubernetes wide open default permissions - since it is so small and has quick startup, an application can be separated in individual parts that are only started up if needed. This leads to less runtime consumption and other benefits - threading and complex bindings lead to problems at compiletime For everybody who is a fan of the famous newsletter "Last week in AWS" (https://lnkd.in/d7iac8Ek) (I couldn't live without it), there is also a kubernetes variant, check it out! https://lwkd.info/ Also had a great time with Carlos Ponce and Hasan Berkay C.! Thanks also to SQUER and Gerald Brose and crew for hosting the event and Max Körbächer for organizing and getting the anniversary merch to Munich in time.

With re:Invent kicking off next week, we expect to see a lot of announcements and hype around the AWS universe. The improvements we've seen in the lead up to re:Invent are already pretty impressive. So, lets use this fantastic opportunity to get together and discover, discuss and enjoy the changes before the Christmas break. Save your seat for the last meetup of the AWS user group in Dresden on Dec 12th: 👉 https://lnkd.in/e7ET6DkP Note that there is a difference how we do these recaps in Dresden compared to other cities. While we will have an overview of the announcements ready, we would be happy if some of our attendees can explain the announcements that they like the most and why. That way we will have more of a discussion about what's hot. Plus, of course I will bring my "cards against developers" game and we can have some fun afterwards 😁 Special thanks to our host, ZEISS Digital Innovation; without the support of companies like you such events would not be possible! 👏 (and of course we are also looking for hosts for 2025 already; ping Paweł or myself if you have some space for a bunch of AWS enthusiasts) #aws #awscommunity #reinvent #dresden

🚀 Why We Built Our Own Kubernetes Management Platform 🚀 Ever tried to tame a wild beast? 🦁 That’s what running Kubernetes can feel like. It’s complex, with countless moving parts and a dynamic environment. Getting your cluster up is just the start. The real challenge begins with Day 2 operations. 🛠️ The Day 2 Dilemma: Ongoing Maintenance 🛠️ Imagine you’ve set up your Kubernetes cluster. Success! 🎉 But now comes the hard part: managing its lifecycle. Manual methods, Ansible scripts, or even Terraform configurations might be your first approach. But these traditional methods won't solve the critical issues in production. Nodes can fail under heavy workloads, needing constant debugging and fixes. Scaling Kubernetes with these outdated methods just won’t work. 🌟 The Birth of Cluster API: A New Hope 🌟 Recognizing these challenges, the Kubernetes community developed Cluster API. This tool allows software to manage cluster lifecycles and react to situations dynamically. Cluster API provides a framework defining an API for clusters and the interaction of components like infrastructure providers. (At Syself, we specialize in developing Cluster API Provider Integrations and build the ones for Hetzner and Hivelocity). It enables an autonomous system by defining a standardized way for clusters and components to interact. 🌐 The Challenge: Building a Production-Ready Platform 🌐 Even with Cluster API, building a production-ready Kubernetes cluster is complex. Kubernetes is often used to host applications that serve millions of users. One wrong move in configuration can have huge impacts, leading to outages and affecting millions. Ensuring seamless updates and operations is critical. 💡 The Cluster Stack: Practical Solutions for Real Problems 💡 Two years ago, we had a vision: the Cluster Stack. A system allowing you to define your Kubernetes Cluster Configuration comprehensively. It includes tools to test configurations extensively, ensuring compatibility before deployment. This systematic process allows reliable upgrades and seamless interaction with autonomous systems like Cluster API. 🌟 The Syself Promise 🌟 With the Cluster Stack, we created a process that makes testing upgrades reliable and ensures seamless interaction with autonomous systems like Cluster API. Choosing Syself means more than a Kubernetes management platform. You get a reliable, production-ready system backed by our global team. We handle the complexities so you can focus on harnessing the power of #Kubernetes.
