Micro vs Monolithic… is not a new discussion From: kt4@prism.gatech.EDU (Ken Thompson) Subject: Re: LINUX is obsolete Date: 3 Feb 92 23:07:54 GMT Organization: Georgia Institute of Technology I would generally agree that microkernels are probably the wave of the future. However, it is in my opinion easier to implement a monolithic kernel. It is also easier for it to turn into a mess in a hurry as it is modified. Regards, Ken

…Didn’t the Monolith win? Wait a Minute…

What’s Wrong with a Monolithic Application? (does your monolith drive you to drink?)

A More Elegant Alternative

How Much More Micro Do You Go?? import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation.Configuration; import org.springframework.web.bind.annotation.* ! // assumes org.springframework.boot:spring-boot-starter-web on CLASSPATH @Configuration @RestController @EnableAutoConfiguration public class GreetingsController { ! @RequestMapping("/hi/{name}") String hello(@PathVariable String name) { return "Hello, " + name + "!"; } ! public static void main(String[] args) { SpringApplication.run(GreetingsController.class, args); } }

The Impact of the Cloud & § Spring Boot makes it dead simple to stand up services.
 (Where do they live? Who runs them?) § Things get Distributed REALLY quickly! CF provides a way to simplify ! ! § Manifests are are the ultimate installer. 
 (cf push an entire distributed system!) ! § Spring Cloud PaaS connectors simplify service-consumption > cf push hystrix.jar > cf push …

Spring Integration and Spring XD § Both make it easy to setup alternative-protocol endpoints ! § Spring Integration can even handle orchestration and messaging ! § Spring XD makes it super-simple to build big-data pipelines

Spring Security and Spring Security OAuth § Spring Security OAuth is a natural way to build REST-centric services with federated identity ! § Whatever else you want, Spring Security provides a solution ! § Spring Session is a turnkey session binding that lets you plugin alternative HTTP session implementations. Can be valuable in scaling out your access-tokens or other ephemeral security state.
