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.

Deployment strategies

In traditional systems, we often dealt with in-place upgrades or simple forms of rolling updates in which we replaced the whole application with a new version. In cloud systems, we have more options to deploy our applications but also have many possibilities to scale them. In this section, we will first have a look at scaling and autoscaling, and in the second step at the different deployment strategies. After that, we will make a short comparison between the different strategies. Finally, we will have a look at some tools that can help us with the implementation of these strategies.

Basics of scaling and deployment strategies

One of the basics of the various deployment strategies is scaling. Normally, we are distinguishing between two types of scaling—horizontal and vertical, as depicted in the following diagram:

Let us look at them in detail:
