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.

Why PCF Dev?


A typical Cloud Foundry deployment, commonly referred to as a Cloud Foundry foundation, can be demanding on the infrastructure it needs to run on. Cloud Foundry requires a significant set of resources from the underlying Infrastructure as a Service (IaaS) it is deployed on, for example, vSphere, AWS, Azure, GCP, and so on. In addition, Cloud Foundry requires a good deal of specialized platform engineering expertise to deploy and properly configure it before the first cf push command can even be issued by an application development team.

The broad-stroke typical resources for common Cloud Foundry deployments can be heavy:

Pivotal Cloud Foundry minimally requires the following:

  • More than 50 GB of memory
  • More than 100 GB of disk space
  • Minimally 2-6 physical CPU cores
  • More than 1 hour to deploy (only once the infrastructure and other requirements are ready)

Open Source Cloud Foundry minimally requires the following:

  • More than 48 GB of memory
  • More than 50 GB of disk space
  • Minimally 2-6 physical...
