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 service models

In the previous sections, we discussed where and how our cloud services can be deployed. In this section, we will talk about who is responsible for which level of maintenance of service and how the most common service levels – Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) – differ. Furthermore, we will discuss the modalities that customers can expect when choosing a certain service model. We will also discuss some service models that are not part of the NIST specification but are also often used in current environments and, therefore, might have relevance for continuous delivery.

In traditional infrastructures, system and network administrators often mounted servers in racks, installed the operating system software on them, and ensured that there was enough storage and a proper network connection to provide a good service where applications could be deployed. These are the services we find in...
