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.

Preface

Monitoring and managing the applications


So far, we deployed our application onto Cloud Foundry. However, the next steps will involve steps on how we can manage and monitor our applications. This can be done in two ways, either through Apps Manager or through the cf CLI. You've already learned how to log on to Apps Manager to create Orgs, Spaces, and add users. With Apps Manager, you are also able to monitor and manage applications as well. We'll explore how to do that in this section. For possible scripting purposes, you may also take the cf CLI route to create, manage, and monitor your application. 

Monitoring and managing the application using cf CLI

Using the cf CLI is just as easy as using Apps Manager. This section will show you how key cf CLI commands are used to manage and monitor your application on Cloud Foundry. We'll split this section into two parts. The first is the monitoring of applications and the second is the management of applications.
