Serverirakendused

Serverirakendused, often translated as server-side applications, are computer programs that run on a server and perform tasks that are requested by a client. Unlike client-side applications that run directly on the user's device, serverirakendused handle the processing, data management, and business logic behind the scenes. When a user interacts with a web application or a mobile app, their device (the client) sends requests to the server. The serverirakendus receives these requests, processes them, and then sends back the necessary information or performs the requested action.

The functionalities of serverirakendused are diverse and essential for modern computing. They are responsible for managing databases, authenticating users, executing complex calculations, generating dynamic content for websites, and facilitating communication between different systems. For example, when you log into a website, a serverirakendus verifies your username and password against stored data. When you search for a product online, a serverirakendus queries a database to find relevant results and then sends them to your browser.

Common technologies used to build serverirakendused include programming languages like Java, Python, Node.js (JavaScript), PHP, and Ruby, often working with frameworks such as Spring, Django, Express.js, Laravel, and Ruby on Rails. These applications are typically deployed on web servers like Apache or Nginx, and they interact with databases such as PostgreSQL, MySQL, or MongoDB. The architecture of serverirakendused plays a crucial role in the performance, scalability, and security of the overall application.
