Simple Message Queue (formerly MNS)
Simple Message Queue, formerly known as MNS, is a developer tool provided by Alibaba Cloud. It allows you to send messages between different applications. This service helps manage communication flows within your software infrastructure. It falls under the broader category of developer tools designed to support application integration.
Choose this service when you need to decouple application components using message passing. Be aware that it operates on a pay-as-you-go pricing model. There is no free tier available, so you will incur costs from the first unit of usage. This structure means you pay strictly for what you consume without any initial free allowance.
