Announcing VMware Performance & Capacity Management, 2nd edition


I have been waiting for a long time to be able to post this. The book started around Dec 2014, when the writing of the 1st edition was complete and the publisher did a cut off date for changes. I knew many items were not covered. It was 1.0 after all.

Fast forward to February 2016, and we have revamped the content. From both the amount of effort, and the resultant book, this to me is more like 2.0 than 1.1. Page wise, it is 500+ pages, doubling the 1st edition. You can see the structure of the second edition in this link. I have tried to codify the knowledge I have into a structured process.

It’s a surprise how much things changed in just 14 months. I certainly did not expect some of the changes back in Jan 2015!

  • Major improvement in monitoring beyond vSphere.
    • vRealize and its ecosystems have huge improvement in Storage, Network, Application monitoring. This includes newer technology such as VSAN and NSX.
    • Many adapters (management packs) and content pack were released for both vRealize and Log Insight. I’m glad to see thriving ecosystems. Blue Medora especially have moved ahead very fast.
  • Rapid adoption of NSX and VSAN, that I had to add them. They were not plan of the original 2nd edition.
  • Rapid adoption of VDI monitoring using vRealize. I had to include VDI use cases.
  • Adoption by customers, partners and internal have increased.
    • In the original plan, I wasn’t planning of asking any partners to contribute. So I’m surprised that 2 partners agreed right away.
    • It is much easier to ask for review, as people are interested and want to help.
  • vSphere 6.0 and 6.0 Update 1 were released.
    • Since the book focus on Operations (and not architecture) and monitoring, the impact of both releases is very minimal.
    • Not many counters changed compared with vSphere 5.5
  • vRealize Operations had 6.1 and 6.2 releases. Log Insight has many releases too.
    • Again, this has minimal impact, since the book is not a product book.

Release Notes of 2nd edition

The existing 8 chapters have expanded and reorganized, resulting in 15 chapters. It now has 3 distinct parts. The 3 parts are structured specifically in that order to make it easier for you to see the big picture. You will find the key changes versus the 1st edition below.

More complete

  • More explanation on Performance and Capacity Management.
  • Elaborates the Performance SLA concept as it has resonates with customers (from engagements, events and blogging)
  • Add Network monitoring, with focus on NSX
  • Add VSAN monitoring.
  • Add Horizon View monitoring. Practical tips like this.
  • Incorporate monitoring that is better done via VMware Log Insight
  • Add application-level monitoring. I asked Blue Medora to contribute as they know this better than I do.

More practical, less theory.

  • Move contents that are more theoretical to the back.
  • Add more examples, and structure them so readers can see the relationship.

Easier to read

  • Less of long sentences, long paragraphs or complex tables.
  • More bullet points.
  • Break long chapters into smaller chunks.
  • Add more white space on places where it’s full of text.
  • More diagrams, to complement explanation.
  • Lighter words. Friendly chat among friends, not formal research paper.
  • Add humour.
  • Add adult picture. Ok, this is not a good idea.
  • Clear picture. Some pictures were too small.
  • Clearer heading and layout. The style heading 2 is relatively too big to the text.

Fix title

  • The book is actually not just for vRealize Operations user. It’s for the broader VMware team. This is more of a vSphere book than vRealize book.
  • This would also make the darn title shorter 🙂 Yes, in future this will evolve to just SDDC Operations Management.

What does not change?

  • It remains focus on Performance and Capacity. I’m not adding Configuration, Availability, Security, etc.
  • The book will also remain a solution book, and not a product book. There is already a great product book here by fellow CTO Ambassador.

I will provide as many free information as possible, that the Publisher allows me. We are looking at early April publication, so in the meantime, here is what they have made available. When they have officially released it, I’d add more information, such as proper acknowledgement to those who have made the book possible, and certainly discount code.

If you want to publish a review in your blog or LinkedIn, I'll link you with Packt.

I hope you find it useful. Any correction and suggestion, let me know at Twitter or LinkedIn.


PS: No, please don’t ask me about the 3rd edition. Right now I need a break 🙂 and to spend time with family! Below is wife, my 2 girls and my 1st niece.
