Agenda

• Briefly introduce Microservices

• Spring Ecosystem

• Couchbase with Spring Data

• Addressing production-ready concerns when building Microservices

Why Microservices?


Spring PlatformSpring Boot, Spring Cloud and Spring Data


From framework to platform

Spring Framework


Spring Framework Ecosystem



Spring Boot



Spring Bootthe opinionated glue that ties all that together



integration of various projects via starters

Spring Boot


Spring Boot

externalized configuration management


Spring Boot

externalized configuration management

CLI > … > JNDI > system properties > OS env > … > .properties outside jar > .properties inside jar …


Spring Boot

auto-configuration


Spring Boot

auto-configuration(not a mystic art)


Spring Boot

monitoring & configuration via actuator


Spring Cloud

use Spring Cloud in Bootfor resiliency and production gradeness


Spring Cloud

Circuit Breaker(Hystrix...)


Spring Cloud

Distributed Configuration


Spring Cloud

Service Discovery(Eureka, Consul...)


Spring Cloud

Load Balancing & MicroProxies(Zuul...)


Spring Cloud

Distributed Tracing(Sleuth, Zipkin...)


Spring Data

use Spring Data in Bootfor data access


Spring Data

Repository abstractionfor CRUD


Spring Data

Template abstractionfor lower level interactions


Spring Data

Query Derivation in repositoriesfor easy querying


And Much More

A lot of other aspects to integrate in Boot


And Much More

A lot of other aspects to integrate in Bootmessaging, session, security, auditing, templating, social ...

Spring Data CouchbaseOverview


Spring & Couchbase

JSON JSON


Repository Pattern

Separate logic that stores and retrieves the data and maps it to the entity model from the business logic that acts on the model


Repository Pattern & Spring Data


Repository Query methods


Repository Query methods


• Secondary Index querying using N1QL

• View Index querying

• Spatial View Index querying

Querying in Couchbase


• N1QL – SQL like query language for JSON

• Secondary Index supports global indexes across the cluster

• Mutlidimensional scaling - Separate index and query service

Secondary Index querying with N1QL






• Built into the data service

• User defined MapReduce Javascript functions to index and filter results

• Uses scatter-gather approach to get results in a multi-node cluster

View Index querying


View Index querying


View Index querying


• Similar to Views with just Map function, built on R Tree

• Index on GeoJson objects as well as other JSON properties

• Open and closed range queries supporting the N-dimensions indexed

Spatial View Index querying


Spatial View Index querying


Production-Ready Microservice


Production-ready microservice’s cross-cutting concerns

• Reliability

• Discoverability

• Observability

• Configurability

• Securability

• Auditability
