java - Which is scalable? Simple CRUD Webapp vs Webapp talking to a REST service -

i think title says clearly. no scalability guru. on verge of creating web application needs scale big info sets , perchance many (wont exaggerate here, lets thousands of) concurrent users.

mongodb info repository , torn between writing simple play! webapp talking mongodb versus play! app talking rest service app (in scala) heavy lifting of business logic , persistence.

part of me thinks having business logic wrapped service future proof , allows deploying webapp in multiple nodes (scaling). come java ee stack , play! rebel in java web frameworks. approach assures me can move away play! if needed.

part of me thinks play! app + scala service app additional complexity , mayn't fruitful in long run.

any suggestions appreciated.

note: newbie scala, mongodb , play!. pardon me if question silly.

scalability engineering science art. means have lots of parameters , apply experience specific values of these parameters come solution. general advice, without more specific info problem, hard.

having said that, experience, general advice:

keep application clean , simple possible. allows maintain options open. in case, start simple play app. concentrate on clean code can rework have different architectural model (with clean code, that's simpler you'd think :-)) measure, not guess, bottlenecks are. it's simple plenty flood server requests. utilize profiling, memory dumps, whatever, pinpoint bottleneck in scalability.

only then, working app in hand (which launch with) , info on scaling bottlenecks are, can create decisions on split off in (horizontally scalable) services.

on outset, services nice , scalable, in mess - services need communicate each other, start introducing messaging, etcetera. maintain simple, measure, optimize.

intellij idea - Update external libraries with intelij and java - simple plenty really. i'm using apache jars, i'll create changes jar's every often. these jars listed external libs in intelij (i.e classpath looking install dir of jar's). when create changes intelij doesn't seem know new implementation. have remove jar external library , re-ad it. does know have intelij picks changes automatically ? i've done clean , rebuild project had little effect. you can go preferences -> build, execution, deployment -> build tools -> maven -> importing , check box says import maven projects automatically . in mac, can command + shift + a , come in action reimport , click on reimport maven projects . intellij-idea
