2 Agenda What are microservices? What do we need to be successful? How does Spring make it better? Q & A

3 Microservices are the solution Now tell me your problem.

4 Monoliths do we have to change? But we ve always done it this way Easy to understand Tried and true Lots of experience Where does this break down? Limited scaling Gets complicated in a hurry Deployments are hard and scary

5 Microservices are they really that different? Monoliths Microservices

6 Microservices are they really that different? Monoliths Shared code / shared libraries Microservices Code duplication / transparency

7 Microservices are they really that different? Monoliths Shared code / shared libraries Reusable APIs shared by many Microservices Code duplication / transparency Bespoke APIs for specific business solution

8 Microservices are they really that different? Monoliths Shared code / shared libraries Reusable APIs shared by many Enterprise data model / single source of truth / system of record Microservices Code duplication / transparency Bespoke APIs for specific business solution Fit-for-purpose data models / duplicate data / system of engagement

9 Microservices are they really that different? Monoliths Shared code / shared libraries Reusable APIs shared by many Enterprise data model / single source of truth / system of record Stable resilient infrastructure Microservices Code duplication / transparency Bespoke APIs for specific business solution Fit-for-purpose data models / duplicate data / system of engagement Unstable / inconsistent / shared infrastructure

10 Microservices are they really that different? Monoliths Shared code / shared libraries Reusable APIs shared by many Enterprise data model / single source of truth / system of record Stable resilient infrastructure Scale up with bigger hardware Microservices Code duplication / transparency Bespoke APIs for specific business solution Fit-for-purpose data models / duplicate data / system of engagement Unstable / inconsistent / shared infrastructure Scale out with more instances

11 Microservices are they really that different?

12 You must be this tall to use microservices These are things you must have in place to be successful: Monitoring Rapid provisioning Automated repeatable deployments

13 We get a lot from Bluemix Rapid provisioning Auto-scaling Logging aggregation (Logmet) Databases on demand (Compose.io)

14 Let s make it even better Spring Cloud: Service discovery Configuration management Intelligent routing Fault Tolerance Ansible / UrbanCode Deploy: Automated repeatable deployments

15 Spring Boot / Spring Cloud Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". Make JAR not WAR Reclaim the main Convention over configuration

16 It s really this easy

17 Let s make it even better Spring Cloud: Service discovery Configuration management Intelligent routing Fault Tolerance Ansible / UrbanCode Deploy: Automated repeatable deployments

18 Service Discovery Spring Cloud Netflix Eureka A name is all you need Integrates well with Spring Cloud

19 Let s make it even better Spring Cloud: Service discovery Configuration management Intelligent routing Fault Tolerance Ansible / UrbanCode Deploy: Automated repeatable deployments

20 Configuration management Spring Cloud Config Seamless integration with Spring Encrypt and decrypt property values Many backends

21 Let s make it even better Spring Cloud: Service discovery Configuration management Intelligent routing Fault Tolerance Ansible / UrbanCode Deploy: Automated repeatable deployments

22 Microservices are they really that different?

23 Intelligent Routing Spring Cloud Zuul Reverse proxy A/B testing

24 Intelligent Routing Spring Cloud Zuul

25 Let s make it even better Spring Cloud: Service discovery Configuration management Intelligent routing Fault Tolerance Ansible / UrbanCode Deploy: Automated repeatable deployments

26 Fault Tolerance Hystrix and Ribbon Circuit breaker (Hystrix) Handle slow responses Graceful failure Sensible defaults Client-side load balancing (Ribbon) Reduce network hops Eliminate single point of failure No extra work to implement

27 Let s make it even better Spring Cloud: Service discovery Configuration management Intelligent routing Fault Tolerance Ansible / UrbanCode Deploy: Automated repeatable deployments

28 Automated deployments worth it! Less errors; more repeatable Anyone in the team can deploy Developers spend their time developing You can release more frequently

29 Automated deployments Lessons learned Only deploy the bits that changed Ansible, Chef, etc. High upfront time investment, long term benefit

30 Summary What are microservices? Microservices promote independence What do we need to be successful? Sophisticated processes required How does Spring make it better? Spring Cloud makes it easy Q & A
