The document is a beginner's guide to Spring Cloud, covering its background, key projects, and components essential for building cloud native applications. It discusses components like configuration services, service discovery, routing and messaging, API gateways, circuit breakers, and tracing, aiming to simplify the development process for developers. The guide emphasizes the importance of using Spring Cloud to provide useful defaults and centralize configurations across environments.

Why Spring Cloud?
• In general, cloud native apps are a good thing, just not easy
• It is easy for big companies to put forth the resources to succeed with Cloud
Native, but what about the little guys?
• Why do we have to reinvent the wheel each time someone wants to build a Cloud
Native app?
• Follow the Spring Boot model of providing useful defaults for Cloud Native apps
with the ability to easy configure them
• Cloud Agnostic

Configuration
• We want to remove the configuration out of
the application to a centralized store across
all environments
• Spring cloud Config Server can use Git, SVN,
filesystem and Vault to store config
• Config clients (microservice apps) retrieve
the configuration from the server on startup
• Can be notified of changes and process
changes in a refresh event

Service Discovery
• With the dynamic nature of any cloud native application, depending on things like
URLs can be problematic
• Service Discovery allows micro services to easily discover the routes to the
services it needs to use
• Netflix Eureka
• Zookeeper
• Consul

Routing and Messaging
• Your cloud native app will be composed of many microservices so communication
will be critical
• Spring Cloud supports communication via HTTP requests or via messaging
• Routing and Load Balancing:
• Netflix Ribbon and Open Feign
• Messaging:
• RabbitMQ or Kafka

API Gateway
• API Gateways allow you to route API requests (internal or external) to the correct
service
• Netflix Zuul
• Leverages service discovery
and load balancer
• Spring Cloud Gateway

Circuit Breakers
• Failure is inevitable, but your user’s don’t need to know
• Circuit breakers can help an application function in the face of failure
• Netflix Hystrix

Tracing
• A single request to get data from your application may result in an exponentially
larger number of requests to various microservices
• Tracing these requests through the application is critical when debugging issues
• Spring Cloud Sleuth and Zipkin

CI Pipelines and Testing
• Building, testing, and deploying the various services is critical to having a
successful cloud native application
• Spring Cloud Pipelines is an opinionated pipeline for Jenkins or Concourse that
will automatically create pipelines for your apps
• Spring Cloud Contract allows you to accurately mock dependencies between
services using published contracts
