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.

Chapter 3. Getting Started with PCF Dev

TDD or test-driven development is essential to the 3 pillars of great software development:

  • Test-driven development (TDD
  • Continuous integration and continuous deployment (CI/CD)
  • Pair programming

However, to execute the TDD loop quickly and to make TDD worth doing from the moment their hands are placed on the keys, developers prefer to shorten the cycle of code deployments as much as possible. While balancing the necessity of running their code against a locally running environment that reliably mimics the production environment the code will eventually run in. And, with as few hops as possible over potentially latent or, in highly secured facilities, a nonexistent internet connection. And, just as importantly, to avoid much of the trouble and toil that arises from differences between these local environments where code is developed and the production environment from which the code will ultimately serve the world.

Enter PCF Dev.
