After shifting our mindset toward an AI-First architecture in the previous episode, it is now time to get our Infrastructure ready. Our goal today is to build a stable and scalable environment for the AI projects we will be diving into throughout this season.\u003C\u002Fp>\u003Cp>Having a solid infrastructure is like laying a strong foundation for a skyscraper. Since AI workloads are resource-intensive and libraries evolve rapidly, establishing a standardized toolset from the very beginning is crucial.\u003C\u002Fp>\u003Ch2>Why Go 1.2x + Docker?\u003C\u002Fh2>\u003Cp>In the world of AI development, where models and libraries change on a weekly basis, running code directly on your local machine (Native Host) often leads to the classic \u003Cstrong>\"It works on my machine\" \u003C\u002Fstrong>problem. This is why the pairing of Go and Docker has become our go-to standard.\u003C\u002Fp>\u003Cul>\u003Cli>\u003Cp>\u003Cstrong>Docker (Consistency & Portability):\u003C\u002Fstrong> Docker ensures that your Development (Dev) and Production (Prod) environments are 100% identical.
