Red Hat SummitChapter 3. Introduction to example applications
Examples are working applications that demonstrate how to build cloud native applications and services. They demonstrate prescriptive architectures, design patterns, tools, and best practices that should be used when you develop your applications. The example applications can be used as templates to create your cloud-native microservices. You can update and redeploy these examples using the deployment process explained in this guide.
The examples implement Microservice patterns such as:
- Creating REST APIs
- Interoperating with a database
- Implementing the health check pattern
- Externalizing the configuration of your applications to make them more secure and easier to scale
You can use the examples applications as:
- Working demonstration of the technology
- Learning tool or a sandbox to understand how to develop applications for your project
- Starting point for updating or extending your own use case
Each example application is implemented in one or more runtimes. For example, the REST API Level 0 example is available for the following runtimes:
The subsequent sections explain the example applications implemented for the Node.js runtime.
You can download and deploy all the example applications on:
- x86_64 architecture - The example applications in this guide demonstrate how to build and deploy example applications on x86_64 architecture.
s390x architecture - To deploy the example applications on OpenShift environments provisioned on IBM Z infrastructure, specify the relevant IBM Z image name in the commands.
Some of the example applications also require other products, such as Red Hat Data Grid to demonstrate the workflows. In this case, you must also change the image names of these products to their relevant IBM Z image names in the YAML file of the example applications.
