Serverless application architectures are gaining popularity due to their ability to build and iterate on products faster with less infrastructure maintenance. This tutorial demonstrates how to create a serverless, SEO-friendly CMS-powered blog using React, ButterCMS, and Netlify. By leveraging the proprietary API-based CMS and content API of ButterCMS, developers can manage content efficiently and integrate it into their frontend applications. The tutorial covers setting up the project, creating routes, building the blog, adding head elements, prerendering, deploying to Netlify, and addressing potential issues such as 404 errors. With this approach, developers can focus on software development without worrying about server maintenance, outages, or scaling bottlenecks.
