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.

Route services


We've visited the concepts of services, user-provided services, and custom service brokers. What if there was a requirement to provide services to applications on the basis of incoming traffic to that application? That is, provide some processing/analysis and action on incoming request traffic for a given application, before it reaches the application. This is what route services provide. Route services can be instantiated through service brokers in the marketplace or through user-provided route services. We'll explore these in detail in this section. Alternatively, this could be done in a microservice fashion using a service registry to perform container-to-container networking. However, this would not be in the form of a service that is using the service capabilities of Cloud Foundry.

Enabling route services

In order to use route services, the platform operator must update the cf-release manifest with an appropriate passphrase and additional configurations relating to enabling...
