i'm trying understand layout of microservices pattern. given each microservice run on over vm (for sake of example) how database fit architecture? would each service, in turn, connect consolidated database read/write data? thanks insight there's no 1 size fits solution. the general principle each microservice should make right decision in terms of right persistence architecture should be. might connected central sql database, or using filesystem, or using nosql data store, or memcached, or whatever. (this why people talk eventual consistency lot microservices.) you want way capture benefits of microservices. you want each microservice independently shippable, you're not blocked on anything. stronger coupling centralized infrastructure reduces independence of microservice. persistence requirements highly variable. if you're running search microservice, don't need acid semantics of typical sql database. if you're doing payments, need acid...

these days looking scala writing non-blocking restful api. have done couple of projects in node.js , curious scala time around. my findings till have been impossible write 100% asynchronous code in scala of underlying code blocking. can find tutorials on how use jdbc in scala application database connectivity. jdbc being blocking means application using can't work in single threaded environment queue other requests while waiting db response.play framework recommends increasing thread pool when using blocking apis means going started. as node.js, available modules have been written asynchronously. specially of database connectors , file handlers read/write asynchronously keeping in mind nothing can block when have single thread. yet see people favoring scala on node.js type safety , computation power while being asynchronous. asynchronous behavior doesn't reflect in of tutorials , resources available online. my question is, me failing understand or there confusion in j...
