Strategizing Continuous Delivery in the Cloud

By: Garima Bajpai, Thomas Schuetz

Overview of this book

Many organizations are embracing cloud technology to remain competitive, but implementing and adopting development processes while modernizing a cloud-based ecosystem can be challenging. Strategizing Continuous Delivery in Cloud helps you modernize continuous delivery and achieve infrastructure-application convergence in the cloud. You’ll learn the differences between cloud-based and traditional delivery approaches and develop a tailored strategy. You’ll discover how to secure your cloud delivery environment, ensure software security, run different test types, and test in the pre-production and production stages. You’ll also get to grips with the prerequisites for onboarding cloud-based continuous delivery for organizational and technical aspects. Then, you’ll explore key aspects of readiness to overcome core challenges in your cloud journey, including GitOps, progressive delivery controllers, feature flagging, differences between cloud-based and traditional tools, and implementing cloud chaos engineering. By the end of this book, you’ll be well-equipped to select the right cloud environment and technologies for CD and be able to explore techniques for implementing CD in the cloud.

Cloud-native platforms and considerations

The Cloud Native Computing Foundation (CNCF) defines a cloud-native infrastructure as one with “microservices, service meshes, infrastructure as code, containers, immutable infrastructure, and declarative APIs” as typical characteristics. We have already looked at the application basics that support embracing cloud-native infrastructure by moving from monolithic to microservices-based architecture. In this section, we will look at the other key cloud-native characteristics of infrastructure:

  • Infrastructure as Code (IaC): By describing our infrastructure resources as code, they can therefore be stored in source control systems. IaC tools utilize a declarative language to describe the desired state and have the operational knowledge to know how the desired state can be reached.
  • Immutable infrastructure: This states that infrastructure is provisioned in such a way that it cannot be modified once it’s running. Therefore...
