Summary

This approach, with a simple website supported by serverless functions and a serverless database, will scale incredibly well and is very fast to develop. One particularly important thing to note is the total separation of frontend and backend development—this will free both disciplines of development to progress rapidly. Generally, frontend developers would use a SPA framework such as Angular, React, or Vue to produce an interactive web application, but it's equally possible to use vanilla JS or jQuery to call the serverless backend. In the next chapter, we will be covering asynchronous processing and caching as a way to increase the scalability of serverless architecture.
