serverprogrammens

Serverprogrammens, a term used to describe software that runs on servers to provide services to client applications over a network, correspond to what English-language sources call server programs or server software. They accept requests, perform computations, access data, and return results. In a client–server model, clients initiate requests while servers manage resources, enforce access control, and ensure reliability and scalability.

Server programs are typically organized by service role. They can run on dedicated hardware, virtual machines, or containers, and are commonly deployed behind load balancers to achieve higher availability. They may be stateful or stateless and can be designed for horizontal scaling, fault tolerance, and rolling upgrades.

Common types of server programs include:

- web servers that deliver web pages and APIs

- database servers that store and query structured data

- application or business logic servers that execute server-side code

- file servers that provide centralized storage and sharing

- mail servers that handle routing and delivery of email

- game servers and media streaming servers

Networks and protocols: server programs communicate using standardized protocols such as HTTP/HTTPS, FTP/SFTP, SMTP, IMAP/POP3, and database protocols. They may expose interfaces via APIs, RPC, or message queues, and often operate within larger architectures such as microservices or service-oriented architectures.

Security and maintenance: server programs require regular updates, proper configuration, encrypted connections, access control, monitoring, backups, and incident response planning to protect data and services.

Examples of well-known server programs include Apache HTTP Server, Nginx, Microsoft IIS, MySQL, PostgreSQL, Oracle Database, Tomcat, and Postfix.
