KubernetesCloud Native Berlin 🇩🇪 Meetup is celebrating the ✨ 10th anniversary of Kubernetes✨ 🔍 Join Karim Shakirov to explore a strategic method of autonomously and continuously optimizing your #K8s environment using a combination of Karpenter, Keda, and pod right-sizing. 💡 #HPA, #VPA, and Cluster autoscalers help efficiently manage clusters to ensure resilience and availability with minimal resources. However, achieving continuous, effective pod right-sizing remains a significant challenge due to several factors: - Shifting left resource allocations - Seasonality - Continuous delivery These factors introduce constant changes into the environment. To keep your environment continuously optimized for both cost and performance, you need a strategic approach combined with the right tools. Register now!

If you got Cilium, then you definitely gotta have Gateway API as well. I mean, why not, right? It makes total sense cause it's more flexible than Ingress and has more capabilities than its cousin. Anyway, I'm not here to convince you which to pick (psst... pick Gateway API)... I'm here to announce the new article I published just today for installing cert-manager and fetching TLS certificates by integrating your preferred cloud provider. It goes from the installation of the operator in the Kubernetes cluster, creating the issuer, fetching a TLS certificate, and what's good without a concrete example if there wasn't an HTTPS application exposed at the end (spoiler alert, there is an example). Enjoy reading, and if you like the content, share it with your network. #kubernetes #cilium

On Aug 7, Oliver Zihler & Alina Liburkina will speak about: From EventStorming to Test-Driving Aggregates. Last time, we showed how EventStorming, DDD, and Clean Architecture can help us foster shared mental models between domain experts and developers effectively. This time, we will focus on one main variation of EventStorming, Design-Level EventStorming, to demonstrate how we can effectively employ it during iteration planning to split user stories and derive business rules and aggregates, such that we can then use the EventStorming diagram to directly create test cases for Test-Driven Development. We will then demonstrate how to test-drive an aggregate from no code to existence using TDD in baby-steps. In this coding part of the session, besides iterating on basic TDD tools like the rule of 3, fake it, obvious implementation with transformation priority premise (TPP), triangulation, or ZOMBIES, we will also demonstrate how software design is done in the refactoring phase and show how refactoring tools like “Parallel Change” can effectively, and safely, replace code structures like single with multiple values in baby-steps, without breaking any code, nor breaking tests, in the process. This session focuses on integrating various tools and techniques to effectively develop software from story to implementation within an agile, domain-focused context. ABOUT OLIVER Oliver is a technical agile coach, technical trainer, and software engineer that promotes, teaches and coaches on DDD, XP, refactoring, Ports & Adapters (and its variations) and other related agile software development topics. - LinkedIn: https://lnkd.in/dkHB_YHF - GitHub: https://github.com/ozihler ABOUT ALINA Alina is a technical trainer, consultant, software engineer and (IT) event organizer passionate about DDD, Refactorings, Hexagonal and Clean Architecture.

Hey! I decided to blog again and my first post is about my first open-source contribution to Terraform-Provider-AWS. https://lnkd.in/e9VbpYQ2 I'm planning to write more about platform engineering and coding, so stay tuned! :) #terraform #platformengineering #golang

Recap of our talk at KCD Munich ✈️ Last week we gave a talk at Kubernetes Community Days Munich about the #opensource project #clusterstacks that we work on in cooperation with Sovereign Cloud Stack. The Cluster Stacks are the backbone of the new Syself Autopilot. 👉 The goal of the Cluster Stacks is to build an open-source Kubernetes as a Service solution based on Cluster API. 👉This KaaS solution is supposed to be extremely user-friendly and allows you to create and update clusters easily and quickly. 👉It is designed to be extremely reliable for users as well as for those managing the Kubernetes platform, by bundling together all configurations of a Kubernetes cluster. 👉These bundles can be tested extensively before they are shipped to users. 👉The tools to use and build these bundles are out there and ensure a good user and developer experience! Can't wait to start building your own Kubernetes platform? Then check it out! https://lnkd.in/eF76waeQ Do you rather prefer a hosted solution? Have a look at our docs or book a free demo with us! https://syself.com/docs https://syself.com/demo Did you miss our talk at KCD Munich? Don't worry, there will be a video of the full talk soon 😃 #syself #kcdmunich #devops #kubernetes #clusterapi

Great talk where Roman Boiko and 💻 Daniele Frasca dive deep on how ProSiebenSat.1 Media SE use Kafka and EventBridge Pipes. They will guide you through the journey of optimizing Kafka, why they went with Confluent Kafka instead of Amazon MSK and how they integrated Kafka with Amazon EventBridge Pipes. They will discuss the benefits as well as the limitations and issues. They also discuss the specific architectural patterns such as the Claim-check and Point-to-point fan-out to enhance resilience and efficiency. https://lnkd.in/eDrX9TPh
