Front End and Back End Services

Serverless Computing

Serverless computing refers to the practice of delivering backend services on a per-user basis. Users can build and station code without having to worry about the underlying infrastructure using a serverless supplier.

Because the service is auto-scaling, a firm that uses backend services from a serverless vendor is charged depending on their calculations and does not have to reserve and pay for a fixed amount of bandwidth or number of servers. Physical servers are still used despite the moniker serverless, although developers do not need to be aware of them.

How Front End & Back End Work

Let's pretend you're running a website that sells movie tickets. When a user types a website address into their browser's address bar, a request is sent to the backend server, which answers with the website data. The user will next see the website's frontend, which may indicate screening times, cast, and dates for the user to complete.

When the user clicks the “submit” button, another request is sent to the backend. The backend system checks its database to see if a movie with this name exists, and if so, when and how many tickets are available for their selected date and time.

The data will then be passed from the backend to the frontend, which will present the results in a fashion that makes sense to the user. A similar back-and-forth communication between the frontend and backend will occur when the user registers an account and inputs financial information to purchase tickets.

Front End Services

The visual layout is an example of the frontend, which is the part of the application that users view and interact with. The frontend service is in charge of showing the appropriate material on various target devices and systems (smartphones, desktop browsers, wearables such as smartwatches, etc.) swiftly and optimally for each display.

Front-end development is client-side programming that creates a professional and engaging user experience and user interface by primarily employing HTML, CSS, and JavaScript programming languages.

Back End Services

The backend is the part of the application that the user doesn't see; it includes the server that stores the application's files and the database that stores user data and business logic. It is a platform that reduces or eliminates the need for developers to perform time-consuming and complex backend server activities.

It enables developers to concentrate on frontend functionality and user experience. Any form of backend service can be used. It could be a data service, a web service, a Java service, a security service, or an API provided by a third party. Alternatively, you might write your own code to extend functionality.
