 ## Implementation background
 It is necessary to introduce the server-side thread strategy in more detail to deepen the user's judgment basis for selecting server-side asynchrony. It is also necessary to introduce coroutines, the "secret weapon" often used in server-side asynchrony.

 1. DNS: The default Kubernetes service is based on the DNS plugin (The latest version of the recommendation is coreDNS), one proposal on Dubbo is about this.  since HSF/Dubbo has always highlighted its soft-load address discovery capability, it ignores Static's strategy insteadily, my understanding is that as a service discovery mechanism, the static resolution mechanism is one of the simplest and most needed to support mechanism, you can also refer to Envoy's point of views. While at the same time, ant's SOFA has always supported this static strategy, it can provides an explanation for an engineering fragment of the SOFA project. There are two advantages to doing this. 1) When the soft load center crash is unavailable and the address list cannot be obtained, there is a mechanism to Failover to this policy to handle certain requests. 2) Under LDC/unitization, the ant's load center cluster is deployed in the equipment room/area. First, the LDC of the soft load center is guaranteed to be stable and controllable. When the unit needs the request center, the address of the VIP can come in handy.

It has not only been validated by Ali's massive traffic in e-commerce scenario, but also been widely implemented in domestic technology companies.
 
 In practical application scenarios, Apache Dubbo is generally used as the implementation framework for RPC calls between back-end systems, and when HTTP interfaces need to be provided to the front-end, the Dubbo Service is packaged as an HTTP interface through a "glue layer" and then delivered to the front-end system.
