Statelessarkkitehtuuryhmän

Statelessarkki is a theoretical concept in distributed systems and computer science. It refers to a system or component that operates without maintaining any internal state from one request to the next. This means that each request is treated as an independent transaction, and all the necessary information to process that request must be provided by the client with the request itself.

The principle of statelessness is fundamental to the design of many modern web services, particularly RESTful APIs. In a stateless system, the server does not need to store information about previous interactions with a specific client. This significantly simplifies server-side development and management, as there's no need to worry about session management, data consistency across multiple requests, or server failures affecting client sessions.

Benefits of statelessness include improved scalability, as new server instances can be added or removed without impacting existing clients. It also enhances reliability; if a server fails, another server can seamlessly take over without losing any client-specific context. However, stateless systems can sometimes lead to increased network traffic, as clients may need to resend redundant information with each request. The responsibility for managing state, such as user preferences or shopping cart contents, then shifts to the client-side application.
