There is a need to break down large monolithic structures into smaller, independent pieces called microservices, which offer clarity of functionality, reduced surface area to test, less brittleness, promoted team autonomy, and easier comprehension and adoption. Microservices can be used in conjunction with JAMstack architecture, where prebuilt applications are served via a CDN without web servers, allowing for dynamic experiences through serverless functions or APIs. This approach enables modularity, making it easier to reason about complex systems and reducing the risk of unforeseen side effects. By building something, developers can gain hands-on experience understanding how to implement microservices in their own projects, starting with Netlify's Functions playground.
