• CDNs store static content (such as HTML and image files) in multiple locations around the world and are placed between the client and the origin server.

• Similar to CDNs, Edge servers are distributed to multiple locations around the world. But unlike CDNs, which store static content, some Edge servers can run small snippets of code.

In the context of Next.js, CDNs (Content Delivery Networks) refer to the networks of servers that are used to distribute static assets, such as images, stylesheets, and JavaScript files, to users around the world. CDNs can help to improve the performance and reliability of web applications by caching content closer to users and reducing the load on the origin server. Next.js has built-in support for using CDNs to serve static assets. You can configure Next.js to automatically optimize and serve your static assets using a CDN by setting the assetPrefix property in your next.config.js file. For example, you can set the assetPrefix to a URL that points to a CDN, like this: java Copy code module.exports = { assetPrefix: 'https://cdn.example.com' } This will cause Next.js to prefix all URLs for static assets with the specified URL, which will be used as the base URL for the CDN. In addition to using a CDN for static assets, Next.js also supports server-side rendering of dynamic content, which can further improve the performance and SEO of your web application.
