The former principle of loading as much of the work as possible onto the webserver is outdated. Today’s user devices have more than enough resources to run web applications. This also includes mobile devices.

React is the most popular and fastest-growing JavaScript framework. The use of such web frameworks creates a new development architecture, where applications are no longer tied to specific operating systems or web servers.

Modern web APIs can be integrated for any JavaScript client to implement third-party services such as business applications with access to CRM and ERP systems as well as ecommerce functionalities such as payments and subscriptions. Utilizing web APIs can eliminate the need for additional servers.

Because web functions no longer need to be managed in the server, websites can be designed around microservices. A microservice undertakes a narrowly defined task which is initiated, carried out and terminated independently of other microservices.

The tasks carried out at the backend, such as creating, managing and saving content, are separated from the presentation on a frontend device (so the architecture is headless, or decoupled).

The website HTML is no longer generated by traditional frontend web servers, but rather the page is preconfigured, distributed via a Content Delivery Network (CDN), and displayed in the user’s browser.
