Building "Bootiful" Microservices with Spring Boot

Microservices? A thing? Or hype? What does it mean in practice? The answer, like so many Facebook statuses, is complicated. In broad strokes, Microservices offer a refreshed approach to application architecture. Microservices are a new way to describe many of the patterns that have fallen out of large-scale applications in practice over the recent years. There is no doubt that the approach works. The question is: how does one build a microservices architecture? Join Josh Long for this webinar introducing the Spring Cloud project to support building cloud-scale and cloud-ready microservices. Spring Cloud builds on Spring Boot and makes building complex distributed systems and and microservices a snap.

3. Micro vs Monolithic… is not a new discussion

   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.

15. 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 …

16. 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

17. 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.
