Chapter 1,Cloud Foundry Introduction, introduces users to Cloud Foundry by providing background on the product itself and some related concepts. The chapter focuses on Cloud Foundry architecture and containers.

Chapter 2,Cloud Foundry CLI and Apps Manager, walks through all the necessary steps to create an account on Pivotal Web Services (PWS) and use the Cloud Foundry CLI to push a simple application to PWS. The chapter also introduces the reader to the Apps Manager running on PWS.

Chapter 3,Getting Started with PCF Dev, presents the steps required to install and manage Pivotal PCF Dev on your local machine. It explains the differences between a fully provisioned Cloud Foundry deployment and PCF Dev.

Chapter 4,Users, Orgs, Spaces, and Roles,introduces the concepts around Org, Spaces,Roles, and Users to help the reader to structure and manage their Cloud Foundry deployment. It walks through the various Cloud Foundry CLI commands on how to create the Orgs, Spaces, Users, and Roles.

Chapter 5,Architecting and Building Apps for the Cloud, teaches the guiding principles used to develop cloud-native applications, as well as the techniques to migrate and modernize monolithic applications into cloud-native applications.

Chapter 6,Deploying Apps to Cloud Foundry,presents hands-onexperience of creating and managing applications, routes, and services provided in the Cloud Foundry marketplace. It touches on buildpacks and how droplets are created when applications are pushed onto Cloud Foundry through the cf CLI.

Chapter 7,Microservices and Worker Applications, discusses microservice architecture design concepts in the context of Cloud Foundry and explains the worker application concept with a hands-on example. This chapter also explores the resiliency provided by the Cloud Foundry platform itself and provides guidelines on how to develop resiliency into the application using Spring Cloud Services, based on NetFlix OSS.

Chapter 8,Services and Service Brokers, takes a deep dive into the concepts of services, service brokers, and route services. It provides a working example, alongside a usable template for creating and managing custom service brokers. This will be leveraged in the chapter, with a demonstration of how easy it is to deploy the service broker, create a service instance, and bind it to a sample application.

Chapter 9,Buildpacks, introduces the various buildpacks provided by Cloud Foundry and walks through the process of consuming and managing the buildpacks. The chapter will dive into the inner working of buildpacks, followed by a walkthrough of creating a custom buildpack.

Chapter 10,Troubleshooting Applications in Cloud Foundry, provides insights into the different error codes and what they mean, including possible resolutions.

Chapter 11,Continuous Integration and Continuous Deployment, discusses continuous integration, continuous delivery, and continuous deployment strategies in the context of Cloud Foundry. This is followed by the concepts of zero downtime and A/B deployment strategies, which can be used to push new versions of an application into Cloud Foundry without disrupting the end user experience.

This book assumes a medium level of understanding of the Mac OS X operating system. The book will go through a simple setup of Pivotal PCF Dev, which may require a basic understanding of networking and virtualization concepts.

Pivotal PCF Dev can be installed and run your local development machine. However, this book requires that you have enough resources on your local development machine to install PCF Dev. The minimum hardware requirements are as follows:

In this book, you will need the following software list:

Internet connectivity is required to install Pivotal PCF Dev and for DNS resolution. There are options to run PCF Dev in offline mode too.

This book is intended for application developers, engineers, and architects who want to learn key aspects of running and developing applications on the Cloud Foundry platform. If you are seeking to migrate and modernize your applications to run on Cloud Foundry, this book is for you. This book is also ideal for anyone who is seeking to further their knowledge about Pivotal Cloud Foundry or as a reference guide during application development.

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "To get a list of buildpacks currently installed on your target Cloud Foundry Foundation, type cf buildpacks".

A block of code is set as follows:

@SpringBootApplication
@EnableScheduling
@EnableDiscoveryClient
public class FortuneTellerApplication {
@Autowired
FortuneCookieGenerator fortuneCookieGenerator;
....
....
}

Any command-line input or output is written as follows:

$ cf apps 
Getting apps in org pcfdev-org / space pcfdev-space as user...
OK

name requested state instances memory disk urls
spring-music started 1/1 1G 512M spring-music.local.pcfdev.io

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "click on the SCALE APP button."
