Good architecture tips

gistfile1.txt

    microservices in containers without overengineering

    all communications by BUS (easy to monitor everything, easy to add new sites, easy to test, easy to implement business logic )

    all messages in json with schema (allows easy parsing/storage/replay and multiple service versions to coexists)

    central db and Redis NOT in the cluster (shared storage as single point of truth, no cache sync problem)

    api routing with nginx or openresty (http routing inside the gateway, no application gw)

    services announce themselves on boot (easy to monitor, you can have a whole environment startup strategy )
