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.

Services


In Chapter 5, Architecting and Building Applications for the Cloud, one of the necessary requirements for achieving Cloud Ready applications were backing services. A backing service, or service for short, is quite simply any networked service that an application will consume. For example, MySQLSQL Server, and S3 Blob stores for DataStoresRabbitMQ for messaging and emailing services. Note that when we say service, it corresponds to a blueprint of that service. In order for applications to use the service, we must create an instance of the service, or what we call a service instance. Once these service instances are created, an application instance can use these once they are bounded.

That is, these services are actually accessed by application code through some URL or some other form of a locator that potentially require credentials, that is, this could be some form of connection string. When this happens, we say that an application is now bounded to a service instance. For the...
