Overview of this book

Cloud Foundry is the open source platform to deploy, run, and scale applications. Cloud Foundry is growing rapidly and a leading product that provides PaaS (Platform as a Service) capabilities to enterprise, government, and organizations around the globe. Giants like Dell Technologies, GE, IBM, HP and the US government are using Cloud Foundry innovate faster in a rapidly changing world. Cloud Foundry is a developer’s dream. Enabling them to create modern applications that can leverage the latest thinking, techniques and capabilities of the cloud, including: ? DevOps ? Application Virtualization ? Infrastructure agnosticism ? Orchestrated containers ? Automation ? Zero downtime upgrades ? A/B deployment ? Quickly scaling applications out or in This book takes readers on a journey where they will first learn the Cloud Foundry basics, including how to deploy and scale a simple application in seconds. Readers will build their knowledge of how to create highly scalable and resilient cloud-native applications and microservices running on Cloud Foundry. Readers will learn how to integrate their application with services provided by Cloud Foundry and with those external to Cloud Foundry. Readers will learn how to structure their Cloud Foundry environment with orgs and spaces. After that, we’ll discuss aspects of continuous integration/continuous delivery (CI/CD), monitoring and logging. Readers will also learn how to enable health checks, troubleshoot and debug applications. By the end of this book, readers will have hands-on experience in performing various deployment and scaling tasks. Additionally, they will have an understanding of what it takes to migrate and develop applications for Cloud Foundry.

Deploying your first app onto cf using the cf CLI

We discussed buildpacks and services. We instantiated a service to use, but we need to bind it to an application that is deployed on Cloud Foundry first in order to use it. This section will now show you how to deploy the application. For demonstration purposes, this section will use the Hello Spring Cloud sample application. The Hello Spring Cloud is a simple Java web API application that uses the Spring Cloud Connectors library in order to inspect the bounded services and display their connection status. 

To deploy our first sample application, do the following steps:

  1. This project requires Maven, a tool for building and managing Java projects. If not done so already, download Maven from: and follow the installation instructions on the site.
  2. Download or git clone the Hello Spring Cloud repository at
  3. If the sample application was downloaded, extract...
