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

Connectivity is king – connectivity concepts in multi-cloud

Let's get back to our smartphone for a minute. Remember? You take it out of the box, and you want to start working with it. The first thing to do is to connect the phone to the outside world. It's the same with connecting to the cloud. You can make a subscription in any cloud provider and start working in it, but a company would want to have an enrollment to which its workers can securely connect from the company's domain to a specific cloud service. Basically, there are three options to enable that connection: a virtual private network (VPN), direct connections, and using a fully managed broker service from a telecom company or connectivity partner. In the next sections, we are going to have an in-depth look at each of these options.

VPN

One of the most used technologies is the VPN. In essence, a VPN is a tunnel using the internet as a carrier. It connects from a certain IP address or IP range...
