Can Cloudflare replace Amplify's hosting entirely?

No, Cloudflare does not completely replace Amplify's hosting capabilities. Cloudflare primarily acts as a CDN and security layer *in front of* an application, which can be hosted on various platforms, including Amplify. Cloudflare provides the performance, security, and reliability improvements, while Amplify handles the application's code deployment and management. They are complementary technologies, not direct replacements for one another.
