Service Registry

Motivation: Use Nginx as an example

• Nginx is a reverse proxy. It knows the application servers' address because it is inside configuration file. This approach has some limitations:

  • When application servers scale up, needs to update Nginx's config file and restart.

  • When application servers have problems, also need to update Nginx's config file and restart.
