Backend Deep-Dive · Beginner Friendly ~16 min read · Updated for 2026 · No prior experience required If the words Kubernetes and EKS have always felt like a wall of jargon, this is the guide that finally makes them click. We start from absolute zero — what a container even is — and build up, one idea at a time, until you can follow a single user request all the way through a real Amazon EKS cluster and back. Plain English, simple analogies, and a clear mental model instead of a pile of commands. Prefer to read? Everything in the video is written out below. Skim the table of contents and jump to whatever you need. TL;DR — the whole idea in six lines Containers pack your app and its environment together so it runs the same everywhere. Kubernetes is a manager that runs, heals, scales, and connects hundreds of containers for you. Every cluster has a Control Plane (the brain) and Worke...
Backend Deep-Dive · Opinion + Code · ~14 min read · Updated for 2026 Python vs Java for Backend in the AI Era Every few months someone asks me — on YouTube, on Topmate, in a mock interview — "Prashant, should I learn Python or Java for backend?" And every time, I give the same unsatisfying answer: it depends on what you're building. I know that sounds like a cop-out. But I've spent years writing Java in production — Spring Boot services handling real traffic, real transactions, real on-call pages at 2 AM — and I also teach Python, write automation scripts in it, and have built small backends with FastAPI. I'm not neutral because I lack opinions. I'm neutral because I've seen both languages do things the other genuinely cannot do well. This post is my honest, experience-based take. I'll show you the same endpoint built in both Spring Boot and FastAPI, talk about where each one starts to hurt in production, and give you the decisio...
