When you get fresh instance of Oracle Java Cloud, you are assigned with one admin and one managed server. If there is requirement to host multiple environments - demo, production, etc. - one managed server is not enough. Is better to run different environments on dedicated managed servers, this would simplify maintenance. WebLogic 22.214.171.124 partitions are not supported yet for Fusion Middleware, so only choice we have right now - different managed servers per environment.
