The Frontend Cloud is a service that aims to collect industry-best practices into one easy-to-use workflow, integrating new and better solutions as they come. It helps businesses improve the speed and personalization of their applications, which are crucial for user engagement and conversion. The cloud uses globally distributed servers to asynchronously compute and granularly cache user requests, providing consistent availability and optimizing latency. This allows for dynamic personalization without sacrificing speed, making it possible to design user-obsessed applications that offer deeply personalized experiences. By leveraging serverless functions and caching, the Frontend Cloud streamlines the development process, enabling teams to focus on product and creativity rather than performance issues.
