Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Summary


PKI is based on digital certificates used for encrypting or signing data. SSL certificates are used to keep sensitive information sent between vSphere components encrypted so that only the intended recipient can decrypt it. CA signed certificates are used to prevent or reduce the risk of man-in-the-middle attacks. This chapter introduced vSphere 6's new VMCA and discussed how it could be used to alleviate some of the headache surrounding certificate management. We looked at multiple configurations, which include using VMCA signed certificates, using VMCA as an intermediate certificate authority, and using external certificate authority signed certificates, or a hybrid configuration. The Certificate Manager Utility is a command-line utility that assists with the certificate configuration process.

In the next chapter, we will further discuss securing a vSphere environment.
