I have multi module application. To be more explicit these are maven modules where high level modules depends on low level modules. Below are the some of the modules :-
user-management
common-services
utils
emails
For example :- If user management module wants to use any services from utils module, it can call its services as dependency of utils is already injected under user-management.
To convert/call my project truly following microserives architecture, I believe i need to convert each module as independently deployable services where each module is a war module
and provides its services over http(mainly as resful web services) . Is that correct or anything else need to be taken care of as well ?
Probably each modules now has to be secured and authentication layer as well ?
If that's the crux of microservices I really do not understand when someone ask whether you have worked on microservices as to me Its not tool/platform/framework but a simple concept to divide you monolithic application in to smaller set of deployable modules whose services is available through HTTP. Is n't it ? May be its another buzz word.
Update:- Obviously there are adavantages going micro services way like independent unit testablemodule, scalable as it can be deployed on separate machine, loose coupling etc but I see I need to handle two complex concerns also
- Authentication:- For each module I need to ensure it authenticates the request which is not the case right now
- Transaction:- I can not maintain the transaction atomicity across different services which I could do very easily at present
