Microservices demo using Cloud Foundry

Microservice Cloud Foundry Sample

This sample is like the sample for my Microservices Book (English / German) that you can find at https://github.com/ewolff/microservice .

However, this demo uses Cloud Foundry to run the microservices. As a PaaS it requires very little configuration to make the microservices work on this environment.

This project creates a complete micro service demo system with Cloud Foundry. The services are implemented in Java using Spring and Spring Cloud.

It uses three microservices:

• Order to process orders.
• Customer to handle customer data.
• Catalog to handle the items in the catalog.

Cloud Foundry

To use Cloud Foundry you need to install the cf command line tool first, see https://docs.cloudfoundry.org/cf-cli/install-go-cli.html.

Then you need to install Cloud Foundry itself. You can either do a local installation as described at https://pivotal.io/pcf-dev  or get an account at a public Cloud Foundry instance. https://www.cloudfoundry.org/how-can-i-try-out-cloud-foundry-2016/ is a list of public Cloud Foundry provider.

Then a simple cf push in the directory microservice-cloudfoundry-demo will deploy the microservices and the Hystrix dashboard.

The application assumes that the microservices are accessible with the path local.pcfdev.io - that is the default for the local Cloud Foundry installation. A website to access the microservices is deployed at http://microservices.local.pcfdev.io/. The website has links to all the microservices.

Remarks on the Code

The microservices are:

• microservice-cloudfoundry-demo-catalog is the application to take care of items.

• microservice-cloudfoundry-demo-customer is responsible for customers.

• microservice-cloudfoundry-demo-order does implements order processing. It uses microservice-cloudfoundry-demo-catalog and microservice-cloudfoundry-demo-customer. Hystrix is used for resilience.

Note that the code has no dependencies on Cloud Foundry. Only Spring Cloud Hystrix is used to add resilience.
