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.

Chapter 7. Microservices and Worker Applications

A traditional monolithic application is developed as one big application and then deployed as a whole. One of the drawbacks of monolithic applications is that, if one of the modules in the application stops working, then it takes down the entire application, causing significant downtime, which is not desirable. Additionally, the application teams are not agile in releasing new features, making new features available with a release in four to six months.

To be able to release features faster and more effectively, companies started investing in technology and encouraging developers to design applications using Microservices Architecture.

Microservices Architecture is not a new concept and it's getting more attention due to the evolution of new frameworks and design patterns.

In this chapter, we will discuss the Microservices Architecture in the context of Cloud Foundry. In Chapter 5, Architecting and Building Apps for the Cloud, you learned about...
