Water (water breeds all things…)

Water provides a one-stop solution for project development and service governance (which can be understood as a microservice architecture support suite). Developed based on the Solon framework and supports the full Solon Cloud specification; has been running in production for 4 years.

The function is equivalent to: consul + rabbitmq + elk + prometheus + openFaas + quartz + etc., and organically combined. Or approximately equal to: nacos + rocketmq + PlumeLog + prometheus + magic-api + xxl-job + etc.

It is friendly to k8s, supports IP drift, and supports k8s service mapping.
