viestijonopohjaiset

Viestijonopohjaiset refers to a Finnish term that translates to "message queue-based" or "queue-based messaging" in English. This concept describes a software architecture or design pattern where different components or applications communicate with each other indirectly by sending and receiving messages through a message queue. Instead of directly calling functions or services of another component, a sender places a message into a queue. Another component, the receiver, then retrieves messages from the queue and processes them.

This asynchronous communication model offers several advantages. Decoupling is a key benefit, meaning that the sender and receiver do not need to be aware of each other's existence, availability, or implementation details. The sender can continue its operations without waiting for the receiver to process the message, and the receiver can process messages at its own pace. This can improve system responsiveness and throughput.

Message queues also provide buffering capabilities. If the sender generates messages faster than the receiver can process them, the queue acts as a temporary storage, preventing data loss. This resilience is crucial in distributed systems where failures or temporary network issues can occur. Furthermore, message queues can facilitate scalability by allowing multiple instances of a receiver to consume messages from the same queue, distributing the workload. Common examples of message queue technologies include RabbitMQ, Apache Kafka, and Amazon SQS.
