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

How VMware products use SSL certificates


vSphere 6 introduces a new component called the Platform Services Controller (PSC), which is foundational to vCenter and its services. The PSC contains multiple services, which include:

  • License service

  • Single Sign-On (Secure Token Service, Identity Management Server)

  • VMware Directory Service

  • Lookup Service

  • VMware Certificate Authority

  • VMware Endpoint Certificate Store

The new VMware Certificate Authority (VMCA) and VMware Endpoint Certificate Store (VECS) change the way that certificates are deployed and managed in a vSphere environment.

vSphere components, such as vCenter Server, Single Sign-On, and the vSphere Web Client, use SSL certificates to securely communicate with each other and with ESXi hosts.

As of vSphere 6, the VMCA provisioned a signed certificate for each vCenter service and each ESXi host. There are several options for certificate management in vSphere 6: replace existing certificates with VMCA signed certificates, make VMCA a subordinate...
