Hi Florian, in general you can scale ArangoDB for each microservice but you definitely have a close eye on the data models and their scalability. e.g. you leverage ArangoDB graph capabilities and want to scale to a cluster and thereby shard your collections to several instances. In this case you might not see the performance you experienced on a single instance because of network hops from server A to server B within your traversal. With ArangoDB SmartGraphs there is already a solution for sharded graphs in a cluster setup but it depends on your use case and queries if this is the right solution for you. Please note that SmartGraphs is part of ArangoDB Enterprise Edition.
Your second question was if using a global cluster for all your microservices is the better option. This is also possible and it is a personal choice. For both approaches there examples which work successfully in production. I´d like to recommend joining our Startup Program to elaborate more on those questions and get individual answers aligned with your use case and specs.
