Hello everyone, we now have many micro-services, and now we want to develop a unified platform. After logging in through this platform, we can click on the service you want to enter and use it directly after logging in through this platform.
but now there are some problems in the development idea
1: because all services are in the same level 1 domain name, it is feasible for cookie storage to call cookie in each service to confirm registration. However, considering the direct jump to their own services, it may be difficult to expand services in the future. This difficulty is unknown and has not been thought of yet.
2: there is a new feature, micro-services, which are merged through unified routing, but the previous services are quite different and difficult to merge.

so I would like to solicit your opinions on how to design this front-end. Thank you
