- 14. Cloud Native Microservices – Java and Spring Cloud Asir Selvasingh – Principal PM Architect, Microsoft Adib Saikali – Principal Platform Architect, VMware
- 17. References
- 18. What is microservices architecture? suite of small services its own process lightweight independently deployable different programming languages different data storage technologies
- 19. Microservice Catalyst quickly penetrate the market Not interested agility and speed scale
- 20. Microservices popularized by Frameworks Platform Cloud providers Portability across platforms
- 21. Representative companies using Java microservices
- 22. Microservices are analogous to honeycomb aligning start small different materials Repetitive independent integrated grows organically solid abstracted reconstruct
- 23. Monolith & N-Tier TO Microservice architecture transformation
- 24. Microservice principles (1 of 2) •
- 25. Microservice principles – 12 factor app (2 of 2) • • • • • • • • • • • •
- 26. Why use Spring
- 27. What is Spring Cloud?
- 30. Spring Cloud Config Server Cannot embed config inside apps
- 31. Spring Cloud Service Registry No more code or URL dependencies
- 32. Spring Cloud LoadBalancer (client-side) • Moves beyond a single hard-coded server URL to a load-balanced solution • Provides client-side load balancing in calls to another microservice • Distributed systems demand an advanced set of routing and load balancing behaviors for microservice to microservice communications One microservice wants to call another microservice, looks up the service registry, returns all the instances of the calling microservice, caller service headache for which instance it calls
- 33. Spring Cloud Gateway Cannot duplicate or scatter cross cutting measures across microservices – securing, routing, rate limiting, caching, monitoring, hiding services, etc.
- 35. Example - Spring Cloud Gateway and LoadBalancer combined • Two instances of callme-service • Single instance of caller-service, which uses Spring Cloud Balancer to find the list of available instances of callme-service • callme-service ports are generated dynamically • Spring Cloud Gateway is hiding the complexity of our system from external client. It is open on 8080 and is forwarding requests to the downstream based on request context path.
- 36. Spring Cloud Circuit Breaker and Resilience4J Failure is inevitable, but end users need not know
- 37. Example – Spring Cloud Circuit Breaker and Resilience4j @Bean public Customizer<ReactiveResilience4JCircuitBreakerFactory> defaultCustomizer() { return factory -> factory.configureDefault(id -> new Resilience4JConfigBuilder(id) .circuitBreakerConfig(CircuitBreakerConfig.custom() .slidingWindowSize(5) .permittedNumberOfCallsInHalfOpenState(5) .failureRateThreshold(50.0F) .waitDurationInOpenState(Duration.ofMillis(30)) .build()) .timeLimiterConfig(TimeLimiterConfig.custom().timeoutDuration(Duration.ofMillis(200)).build()).build()); } • slidingWindowSize is equal to 5 • If 3 timeouts during last 5 calls, circuit is switched to OPEN state • waitDurationInOpenState is set to 30 milliseconds • after 30 milliseconds the circuit is switched to HALF_OPEN state • permittedNumberOfCallsInHalfOpenState is set to 5 • In this five attempts we get <= 2 timeouts, circuit is switched to CLOSE state
- 38. Spring Cloud Sleuth and Zipkin – Distributed Tracing Debugging distributed apps can be complex and take long time • Spring Cloud Sleuth can instrument apps in a predictable and repeatable way • Zipkin can zero in on latency problems • Together, they trace requests through microservices • Adds trace and span ids to logs • appname: name of the app that logged the span • traceId: ID assigned to a single request, job, or action • spanId: ID of a specific operation that took place • exportable: should the log be exported to Zipkin?

- 40. Capstone (2 of 3) – Spring Cloud Components Spring Cloud Apps Spring Cloud Components Spring Cloud Components Cloud Services App Consumers Breaker dashboard Service registry Distributed tracing Config dashboard IoT Mobile Browser API Gateway Microservices Microservices Microservices Message brokers Databases Build distributed systems by - • Versioning, distributing, and refreshing configuration via config server and management bus • Dynamically discovering remote dependencies • Decentralizing load balancing decisions • Preventing cascading failures through circuit breakers and bulkheads • Integrating on the behalf of specific clients via gateway • Instrumenting apps for distributed tracing
- 41. Capstone (3 of 3) – Migrate Monolith to Microservices - M3 Decompose monolithic applications using three principles
- 43. Spring Microservices – Azure Hosting Options Azure Spring Cloud Tanzu Application Service AKS VMs
