Hello, let me answer this question.

When we use computers, in some cases we may encounter situations where our computers do not start the server service. For this kind of problem, it may be because our system itself does not have the server service turned on, as long as we turn it on manually.

Sentinel uses traffic as the entry point to protect the stability of services from multiple dimensions such as flow control, circuit breaker degradation, and system load protection. Including core independent class library, monitoring console, and rich usage scenario verification. (This seems to be the consistent style of Alibaba’s open source components, which are extremely unique and regular.) Resources are one of the core concepts in Sentinel components. Scripts, static pages, API interfaces, files and pictures on the application server can all be understood as resources. For Java developers, API interfaces are the concept of resources here.

Hope it helps! !
