Microsoft Azure Fundamentals Certification and Beyond

By: Steve Miles

Overview of this book

This is the digital and cloud era, and Microsoft Azure is one of the top cloud computing platforms. It’s now more important than ever to understand how the cloud functions and the different services that can be leveraged across the cloud. This book will give you a solid understanding of cloud concepts and Microsoft Azure, starting by taking you through cloud concepts in depth, then focusing on the core Azure architectural components, solutions, and management tools. Next, you will understand security concepts, defense-in-depth, and key security services such as Network Security Groups and Azure Firewall, as well as security operations tooling such as Azure Security Center and Azure Sentinel. As you progress, you will understand how identity, governance, privacy, and compliance are managed in Azure. Finally, you will get to grips with cost management, service-level agreements, and service life cycles. Throughout, the book features a number of hands-on exercises to support the concepts, services, and solutions discussed. This provides you with a glimpse of real-world scenarios, before finally concluding with practice questions for AZ-900 exam preparation. By the end of this Azure book, you will have a thorough understanding of cloud concepts and Azure fundamentals, enabling you to pass the AZ-900 certification exam easily.

The economics of cloud computing

We'll look at the consumption-based model, one of the two economic characteristics of cloud computing compared to traditional computing economics; the second economic characteristic that cloud computing is based upon is the cost expenditure model of OpEx.

Consumption-based model?

In a nutshell, a consumption model means paying only for what you use, for the time you use the resource; this can be likened to leasing/renting something instead of outright purchasing and owning the asset. Some resources such as virtual machines can be stopped and started to reduce costs, so you only pay while running them; this is one of the key business benefits of the cloud computing cost model over a traditional computing cost model.

This section introduced the consumption-based model of cloud computing. The following section takes a closer look at the cost expenditure models.
