How we achieved seamless k8s upgrades with Zero Downtime 🚀 When managing a system with over 100 microservices and 6000+ production containers, the risk of outages during a Kubernetes upgrade is real. But we thrive on challenges. 👉 Our solution? Immutable infrastructure and a fleet of independent Kubernetes clusters on GCP & AWS. By leveraging GKE, EKS, Golang, Terraform, and our custom eks-cli tooling, our 4-engineer team streamlined cluster creation and automated deployment using a GitOps model. 👉 The result? High availability, reduced maintenance costs, and peace of mind. 🔧 Interested in how we can optimize your infrastructure?

🚀 Terraform Wars: The Great Naming & Modularization Debate 🤔 Terraform users, unite! Ever felt like Terraform is less about infrastructure and more about survival? Let’s dive into one of the biggest debates in the Terraform world: 🥊 One Module for All vs. Different Modules for Each Environment Team One-Module-to-Rule-Them-All: "Why write multiple modules when you can just use variables? Reusability is everything!" Oh sure, reusability is great—until you’re knee-deep in 30 variables and trying to figure out why is_this_even_working = true doesn’t fix your deploy. Team Separate-Modules-for-Everything: "Let’s split it up! More modules = more clarity, right?" Well, until you’re maintaining FOUR copies of the same thing and spending your weekends searching for that one missing tag across environments. Clarity? 🤷‍♂️ Where? And Then... Naming Conventions! 😱 Snake_case? kebab-case? Or how about YOLO_case? Naming AWS resources is like naming your Wi-Fi... It seemed funny at first, but now you're stuck with it forever. Pro tip: If your tags include prod-final-final2, you might need to rethink your life. 🙃 But Seriously… What’s the Answer? Spoiler alert: There’s no perfect answer. It’s all about trade-offs: ✅ A single module works great—until you need a PhD to manage all the conditionals. ✅ Separate modules feel clear—until you’re maintaining clones of the same code everywhere. Most teams start simple, with one reusable module. But as things grow (and let’s be real, they always do), you’ll need to rethink your strategy. Why Does This Matter? - Because Terraform is all fun and games until you inherit a setup named prod-backup-final-FIXED-FIXED2. 🤦‍♀️ And let’s not even talk about bloated modules that feel like mini-black holes. - Terraform isn’t just about managing infrastructure—it’s about keeping your sanity. 🧠 What’s Your Terraform Horror Story? Are you Team “One Module to Rule Them All,” or Team “Split ‘Em All Up”? How do you handle naming wars? 🤷‍♀️ Drop your thoughts (and your funniest naming fails) in the comments! Let’s laugh together—because if we don’t, we might just cry. 😂 📢 #Terraform #InfrastructureAsCode #DevOpsHumor #TerraformModules #NamingConventions #CloudComputing #AWS #DevOpsLife #IaC #TerraformTips #CloudInfrastructure #AWSCommunity #DevOpsEngineer #TechHumor #InfrastructureAutomation

𝗘𝗡 👉 Kubernetes has revolutionized the management of applications in cloud environments and has established itself in many organizations, especially in those with a high demand for cloud flexibility and scalability. It is currently the most popular open-source tool for managing and scaling cloud containers. We have been building Kubernetes competencies at Beyond.pl for years. So far, they have been used for the implementation of complex cloud projects for clients and for internal purposes. Based on the experience gained, we have launched a service dedicated exclusively for the support of projects using K8s technology, Managed Kubernetes. 💡 As part of Managed Kubernetes, we design, implement, monitor, and develop customers' Kubernetes environments. We manage instances regardless of their location - they can be maintained locally, on-premise, at an external provider, or in our data centers. Find out more at 👉 https://bit.ly/3LlvRIo Why choose Managed Kubernetes from Beyond.pl? ✔ 2 types of support levels to choose from - SysOps, where we take care of Kubernetes architecture including system components, and DevOps which includes a comprehensive support of Kubernetes environments including in the application layer. ✔ Support provided by a team of certified specialists - the competencies in containerization support are confirmed by certificates held by internal and external experts cooperating with us. ✔ Time and cost savings - you reduce operational costs, including those related to building internal competencies, and gain more time to focus on strategic initiatives. ✔ Quick access to other IT services - extending support to managed services areas - Managed Network, Disaster Recovery, BaaS, and IT infrastructure maintenance services (colocation, dedicated infrastructure, and managed cloud in multiple models). ✔ Ready-to-go kubernetes cluster - for companies starting out with K8s, we offer the e24kubernestes solution, a configured and ready-to-go environment developed and maintained in the e24cloud. It allows you to quickly deploy Kubernetes clusters without the need to have administrative expertise or to invest into IT infrastructure costs. ✔ Secure location of kubernetes environments - the infrastructure on which kubernetes clusters are maintained at Beyond.pl (e24kubernetes) is located in Data Center 2, one of the most secure data centres in Poland and the EU (ANSI/TIA-942 Rated 4 and EN 50600 Class 4 certification). ✔ Reducing the carbon footprint of the company's IT infrastructure - our data center where Kubernetes clusters are hosted uses 100% renewable energy for power, has high energy efficiency (PUE 1.2) and a low water consumption rate (WUE), placing it among the European leaders in low-carbon facilities. By choosing to locate your K8s instance at Beyond.pl, you are reducing the carbon footprint generated by your company's IT resources. We look forward to working with you! #beyondpl #datacenter #cloud #managedservices #kubernetes

Happy New Week Yesterday at Poshem Technologies Institute during the Azure DevOps masterclass We automated the entire CI/CD process, from a developer's local laptop to the deployment environment, using industry best practices. We worked on our sample ASP.NET app by creating a new feature branch, editing the index file, and adding it to the Git repository. After committing and pushing the changes to our remote Azure Repo, we created a pull request, requiring at least one reviewer before merging to the main branch. Once reviewed and merged, a Continuous Integration (CI) build was triggered. The CI build ran smoothly, performing WhiteSource Bolt security vulnerability checks and SonarQube code quality tests, ultimately generating a build artifact. The Release pipeline then kicked off automatically, initiating Continuous Delivery (CD) and Continuous Deployment (CD) to a staging environment before moving to production. We covered deployment slots in Azure App Service, which are separate instances of your app with their own host names. Deployment slots allows to deploy and test changes without impacting the production environment, it’s a very great stuff. We created a deployment slot called "Staging Environment" in our Azure App Service. Our release pipeline included a stage for “deploying to this staging environment” and a task to deploy the app there. Another stage, "Swap Slot," was added to swap from staging to production once everything was validated. With pre-deployment and post-deployment approvals set for both stages, we approved the changes, deployed to staging, checked our staging web app, and swapped slots, making our application live in production. It was a great learning session! #CICDAutomation #DevOps #Azure #ASPNet #ContinuousIntegration #ContinuousDeployment #TechInnovation #SoftwareDevelopment #CloudComputing #DeploymentSlots #LearningJourney #TechCommunity #ITBestPractices #CodeQuality #SecureDevOps #StagingEnvironment

Pawel Piwosz will be speaking at the DevOps & Agile Summer Retreat! He will talk about "Security testing for Terraform templates" “I hate DevOps, you are not thinking about security!” This is a real quote. Let’s try to prove it is not the truth! Infrastructure as Code is one of the pillars of “best practices” in DevOps world now. It is more and more popular to use it through CI/CD pipelines, but… what about security? Do we really care about it? In this talk we will explore a few Terraform scanners and we will try to answer to one question: are these tools good enough to be security scanners? We're honoured to have you 🎉
