Building VMware Software-Defined Data Centers

By: Valentin Hamburger

Overview of this book

VMware offers the industry-leading software-defined data center (SDDC) architecture that combines compute, storage, networking, and management offerings into a single unified platform. This book uses the most up-to-date, cutting-edge VMware products to help you deliver a complete unified hybrid cloud experience within your infrastructure. It will help you build a unified hybrid cloud based on SDDC architecture and practices to deliver a fully virtualized infrastructure with cost-effective IT outcomes. In the process, you will use some of the most advanced VMware products such as VSphere, VCloud, and NSX. You will learn how to use vSphere virtualization in a software-defined approach, which will help you to achieve a fully-virtualized infrastructure and to extend this infrastructure for compute, network, and storage-related data center services. You will also learn how to use EVO:RAIL. Next, you will see how to provision applications and IT services on private clouds or IaaS with seamless accessibility and mobility across the hybrid environment. This book will ensure you develop an SDDC approach for your datacenter that fulfills your organization's needs and tremendously boosts your agility and flexibility. It will also teach you how to draft, design, and deploy toolsets and software to automate your datacenter and speed up IT delivery to meet your lines of businesses demands. At the end, you will build unified hybrid clouds that dramatically boost your IT outcomes.

Preface

Radical new IT approach


DevOps is a radical and disruptive way of doing IT. It focuses on applications and it tends to ignore hardware beneath the app. This sounds harsh compared to the classic IT approach where servers and the OS is in focus in order to provide a good, secure, and scalable environment for the applications.

In DevOps, applications become stateless since they store the data elsewhere; that might be an object-based storage or a NAS/SAN mount into the container. This means the container can spin up wherever it needs to be, given that it can access its data. There is no means in patching containers - just the container definition (the package) will be updated. To deploy this patch the old container will be destroyed and a new container will be started with the updated service/application code.

Also, containers in DevOps are not a place to install an entire legacy app. Ideally, they house just parts of an app so-called microservices. These microservices can be used to form an app...
