The document provides an overview of microservices, covering aspects such as version control, build pipelines, deployment options, and quality assurance methods. It also discusses microservice ecosystems, including service discovery, configuration management, API gateways, and monitoring tools. Additionally, it highlights specific microservices used in an example application, such as vets-service and customer-service.

3. Pipeline

4. Pipeline
● Version control - everything is in version control
● Commit Build - build, unit-test, static analysis/inspect
● Artifact Repository/Registry - store build once deploy many
● Deployment - options, ecosystem adds challenge
● Quality - automated acceptance testing
● Release - blue green?

5. Pipeline

6. Pipeline, rugged
● OWASP ZAP - Penetration and dynamic
testing
● Jmeter - Performance
● Resilience - Chaos Monkey and Simian Army
● Strong versioning - M.m.p.revision/hash

8. Ecosystem

9. EcoSystem, ours
● Discovery - Eureka locating services for the purpose of load balancing and
failover of middle-tier servers.
● Configuration - externalized configuration in a distributed system
● API gateway - Zuul is a gateway service that provides dynamic routing,
monitoring, resiliency, security
● Admin - Spring Boot Admin is a simple application to manage and monitor your
Spring Boot Applications.
● Tracing - Zipkin is an open source project that provides mechanisms for
sending, receiving, storing, and visualizing traces.

10. EcoSystem, resilience
● Monitoring - ELK, Sysdig
● Service-to-service calls
● Load balancing
● Circuit Breakers
● Global locks
● Leadership election and cluster state
● Distributed messaging
● Security
