Cloud Foundry for Developers

By: Rahul Kumar Jain, Rick Farmer, David Wu

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.

Application migration and the journey to cloud-native design on Cloud Foundry

As briefly mentioned previously, a cloud-native application needs not be a new application from scratch, that is a green-field application; we can achieve a cloud-native from existing monolithic applications. In the context of business: what's important for application migration is to deliver business value and receive a return on investment from that, rapidly, with critical application feedback, which mitigates a number of project risks. We can apply this concept using the cloud-native maturity model. This model serves as a good indicator to benchmark an application's evolution to the epiphany of cloud-native design.


Your application doesn't have to be cloud-native in order to be deployed and running on Cloud Foundry.

Figure 1: The cloud-native maturity model

As can be seen in the preceding figure, the cloud-native maturity model follows the 16 guiding principles of cloud-native design. To achieve the first phase...
