Book description

How can Cloud Foundry help you develop and deploy business-critical applications and tasks with velocity? This practical guide demonstrates how this open source, cloud-native application platform not only significantly reduces the develop-to-deploy cycle time, but also raises the value line for application operators by changing the way applications and supporting services are deployed and run. Learn how Cloud Foundry can help you improve your product velocity by handling many of essential tasks required to run applications in production.

Author Duncan Winn shows DevOps and operations teams how to configure and run Cloud Foundry at scale. You’ll examine Cloud Foundry’s technical concepts—including how various platform components interrelate—and learn how to choose your underlying infrastructure, define the networking architecture, and establish resiliency requirements.

This book covers:

  • Cloud-native concepts that make the app build, test, deploy, and scale faster
  • How to deploy Cloud Foundry and the BOSH release engineering toolchain
  • Concepts and components of Cloud Foundry’s runtime architecture
  • Cloud Foundry’s routing mechanisms and capabilities
  • The platform’s approach to container tooling and orchestration
  • BOSH concepts, deployments, components, and commands
  • Basic tools and techniques for debugging the platform
  • Recent and soon-to-emerge features of Cloud Foundry
