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.

Worker applications


In Chapter 6, Deploying Apps to Cloud Foundry, you learned how to build and deploy a simple web application into Cloud Foundry on PCF Dev. Once the application was pushed onto PCF Dev, the platform created a route to the application that could then be used by the users to communicate with the various endpoints exposed by the application. In this section, we will talk about the applications that have no route, but that run in the background, performing a task. A worker application is basically a process, lower level than a web application, that maps naturally to many so-called back-office jobs.

These applications generally have no API endpoints, and can be treated as the jobs that are run every night, to keep various systems in sync. A worker application can be written in any language and be deployed into Cloud Foundry.

Fortune teller worker application

We will now build a Spring Boot application that will run every five seconds and output a random fortune. Let's call this...
