Multi-Cloud Architecture and Governance

By: Jeroen Mulder

Overview of this book

Multi-cloud has emerged as one of the top cloud computing trends, with businesses wanting to reduce their reliance on only one vendor. But when organizations shift to multiple cloud services without a clear strategy, they may face certain difficulties, in terms of how to stay in control, how to keep all the different components secure, and how to execute the cross-cloud development of applications. This book combines best practices from different cloud adoption frameworks to help you find solutions to these problems. With step-by-step explanations of essential concepts and practical examples, you’ll begin by planning the foundation, creating the architecture, designing the governance model, and implementing tools, processes, and technologies to manage multi-cloud environments. You’ll then discover how to design workload environments using different cloud propositions, understand how to optimize the use of these cloud technologies, and automate and monitor the environments. As you advance, you’ll delve into multi-cloud governance, defining clear demarcation models and management processes. Finally, you’ll learn about managing identities in multi-cloud: who’s doing what, why, when, and where. By the end of this book, you’ll be able to create, implement, and manage multi-cloud architectures with confidence

Understanding data encryption

One of the first, if not the first, encryption devices to be created was the Enigma machine. It was invented in the 1920s and was mostly known for its usage in World War II to encrypt messages. The British scientist Alan Turing and his team managed to crack the encryption code after 6 months of hard work.

The encryption that Enigma used in those days was very advanced. The principle is still the same – we translate data into something that can't be read without knowing how the data was translated. To be able to read the data, we need a way to decipher or decrypt the data. There are two ways to encrypt data – asymmetric, or public key, and symmetric. In the next section, we will briefly explain these encryption technologies, before diving into the services that the leading cloud providers offer in terms of securing data.

Encryption uses an encryption algorithm and an encryption key – symmetric or asymmetric. With symmetric...
