How does the rise of "Jamstack architecture" influence the way we consider web performance and scalability?

Jamstack architecture, which stands for JavaScript, APIs, and Markup, has been gaining popularity as an efficient modern approach to building websites and applications. Unlike traditional web development models, Jamstack decouples the frontend from the backend, delivering pre-rendered content over CDN. This approach promises faster load times, enhanced security, and easier scaling compared to conventional models. With the growing emphasis on web performance, particularly for SEO and user experience, understanding the impact of Jamstack on these parameters becomes crucial. How does this architecture shape the way developers measure and optimize the performance and scalability of their projects, and what does it imply for the future trends in web development?
