About the Book
Part of a series of specialized guides on System Center, this book is specifically designed for architects and cloud fabric administrators who want to understand what decisions to make during the design process and the implications of those decisions, what constitutes best practice, and, ultimately, what to do to build out a virtualized network solution that meets today's business requirements while also providing a platform for future growth and expansion. This second edition includes coverage of the Hyper-V Network Virtualization gateway, designing a solution that extends an on-premises virtualized network solution to an external (hosted) environment, details of how to troubleshoot and diagnose some of the key connectivity challenges, and a look at the Cloud Platform System (CPS) and some of the key considerations that went into designing and building the network architecture and solution for that environment.
