Two weeks ago on Twitter, Ryan Boud who is a senior cloud consultant working for Inframon, asked me if I would be interested in reviewing his book on Hyper-V Network Virtualization (HNV). Sometimes things can go very quickly. About one minute after his tweet, I confirmed my interest, not knowing this was in fact a book published by Packt.
As a side note, I’m personally not very fond of this publisher after a bad experience with them in their rather aggressive approach to candidate writers and quickly learnt they don’t pay very well for the vast amount of work authors put into their writings. As a technical editor for several books by Aidan Finn et al., and having contributed to a book called Microsoft Private Cloud Computing, I had gotten used to being paid for my work. Packt does not pay a cent to technical editors or reviewers, so that’s why I had previously declined my participation on another book.
But as you can see in the tweets above, I had already accepted the review and quickly received an email from Packt, offering me a log in account to their site and a free download of Ryan Boud’s book in pdf, epub, and mobi formats. So I decided to download the PDF and see what this book had in store. Of course I’m interested in anything written on Hyper-V Network Virtualization as it directly relates to the many CloudOS, System Center and Azure Pack projects I am involved in with different service providers and enterprises in Europe.
Hyper-V Network Virtualization was in fact introduced in Windows Server 2012 but was not very useful without a NVGRE gateway. We had to wait until Windows Server 2012 R2 and VMM 2012 R2 came out with all the necessary ingredients to let this baby live in the real world. Microsoft had decided to make an in-box gateway available, which could be implemented on a dedicated Hyper-V server or preferably an HNV cluster. By deploying a VMM Service Template, a single or high available NVGRE Gateway guest cluster could be deployed and managed through VMM. READ MORE »
