Whether you are a complete beginner or switching from another platform, this guide will save you months of confusion. ...

You have worked through all 12 articles in the Kubernetes series. Now it is time to go to production. This checklist covers everything you need to verify before your application is ready for real traffic. Each item links back to the tutorial where it is covered in depth. Going through this checklist before your first production deploy will save you from the most common production failures. Reliability Define resource requests and limits on every container Without requests, the Kubernetes scheduler cannot place Pods correctly. Without limits, one runaway container can OOM-kill an entire node. ...

We also explain German taxes so you know what you actually take home. Average Software Developer Salary in Germany (2026) Here are the typical annual gross (brutto) salaries for software developers in Germany: ...

Your app works great with 2 replicas at normal traffic. But at peak hours it gets 10x more requests. And at 3 AM it gets almost none. Running 10 replicas around the clock wastes money. Running 2 replicas at peak is too slow. Kubernetes can scale your application automatically — up when traffic is high, down when it is quiet. This tutorial covers three autoscaling tools. Three Types of Scaling Type What scales Tool Horizontal Number of Pods HPA, KEDA Vertical CPU/RAM per Pod VPA Cluster Number of nodes Cluster Autoscaler Horizontal scaling adds more copies of your app. Vertical scaling makes each copy bigger. Cluster autoscaling adds more machines to the cluster when all machines are full. ...

Python is one of the most popular languages in 2026. It dominates AI/ML, web development, data science, and automation. This guide covers the 30 most common Python interview questions. Answers are short and practical with code examples. Quick Reference — Python Key Features Feature Description Dynamically typed No need to declare types (but type hints are recommended) Interpreted Runs line by line, no compilation step GIL Global Interpreter Lock limits true multi-threading Indentation-based Uses whitespace instead of braces for blocks Duck typing “If it walks like a duck…” — type is determined by behavior Garbage collected Automatic memory management with reference counting Batteries included Large standard library for common tasks Package manager pip (or uv for faster installs) Beginner Questions (1-12) 1. What is Python? Python is a high-level, interpreted, dynamically-typed programming language. It was created by Guido van Rossum and released in 1991. Python emphasizes readability with its use of indentation. It is widely used for web development, AI/ML, automation, and data analysis. ...

A Kubernetes cluster has many attack surfaces. Misconfigured Pods can break out of their namespace. Overprivileged service accounts can access the entire cluster. Unscanned images can run with known vulnerabilities. This tutorial covers the essential security practices before taking any Kubernetes application to production. The 4Cs of Cloud Native Security Think of Kubernetes security in layers: Cloud → Cluster → Container → Code Code — vulnerabilities in your application code Container — image security, running as non-root, minimal base images Cluster — RBAC, Pod Security Standards, Network Policies Cloud — network firewall rules, IAM policies, cloud provider security Each layer depends on the one below it. Fixing only one layer is not enough. This tutorial focuses on the Container and Cluster layers. ...
