Recently I stumbled at a book Things That Make Us Smart by one of my favorite authors Donald Norman. In the book, he shared many insights on the complex human machine interactions, “arguing for the development of machines that fit our minds, rather than minds that must conform to the machine.” By the way, I highly recommend his another book The Design of Everyday Things.
Because I just blogged about IT automation, I still have that topic on my mind. So when I read the book, I did quite a lot of reflective thinking around IT automation. In general, I feel Read more...
Distributed Power Management (DPM) is a powerful (powerless, really) feature can reduce host power consumption in a DRS cluster. It works in either manual mode or automatic mode only when DRS is enabled. DPM can place idle hosts into standby mode, or awaken them from standby when more resources are needed.
In business world, we hear frequently the word “focus.” To achieve business goals, for example, deliver software, it’s absolutely necessary to focus on the projects and priorities. Teams that focus on execution typically perform better than others that don’t.
It’s, however, not a good idea to focus all the time. In fact, human beings have limited period of attention. Passing that period hurts one’s effectiveness – one explanation, perhaps, for why long working hours don’t deliver proportional results – not to mention the detrimental effects on one’s health.
This is the wrapping tech talk at our last community meetup by Jeff Hu who is the tech lead on vSphere APIs. Based on his 7 years of experience since the inception of vSphere API, Jeff shared his insights on the design of vSphere API, and what can be done for better ease of use and consistency. In my opinion, this is a must read for anyone who is interested in VMware management APIs.

This talk is by Dave Briccetti (@dcbriccetti) who is an independent consultant working at VMware on vCloud related project. He is also a committer on the Lift framework for building Web applications in Scala.
This is by Boris Strongin, VP Engineering and Co-founder, Hytrust Inc at our first community meetup on May 18. He reviews new security, auditing, and compliance challenges coming with cloud multi-tenancy, and approaches to address them.
This is the tech talk by Giridhar Padmanabh(@girip26), who is now a Sr. Manager at Cisco. He joined Cisco not long ago with the newScale acquisition. This tech talk draws on his 7 years of experience at newScale building industry leading software for delivering private cloud as a service.
We had a great community meetup last Wednesday. Check out this post for the photos. Thanks to the speakers, we have the tech talks slides ready for you. If you have missed the event last week, just check out these slides in PDF format. At the same time, we are working to make the recording available. So stay tuned for announcement.
Here is the talk is by me. I reviewed the history, current state, and future road map of the open source vSphere Java API. In the end, I also shared 3 success factors for Read more...
Weeks ago I had a great conversation with Vanessa Alvarez (@VanessaAlvarez1) who is an analyst with Forrest Research. Among other topics, we discussed datacenter automation because we’re both interested in it. After Vanessa tweeted about her automation dream, several follow-up tweets came up.
In general, I think automation is a vague word in IT world, and it mostly means different things to different people. This is especially true when we talk about automation together with integration. This article tries to define automation from my understanding and perspective. Please feel free to share your thoughts in comments.
My colleague John Troyer (@jtroyer), who hosts VMware Communities Roundtable, has posted an interview with Alan Renouf (@alanrenouf) and me about our thoughts on VMware SDKs, APIs, and CLIs on May 18. During the interview, I answered questions about the open source vSphere Java APIs, the themes of my blogs (why it’s called doubecloud), what I am doing now at VMware, and of course our first community meetup event on the same day. If you have missed the session, you can listen to it now: , or here. Read more...
Our first community meetup event on Wednesday night was a great success. It attracted about 200 developers/QAs and administrators globally either on site or online with live streaming. An EMC development team flied all the way from Irvine to join us; so did Huawei Symantec from Chengdu of China.
At the end of the meetup, we gave way 20 copies of these books: VMware VI and vSphere SDK by me, VMware vSphere 4.1 HA and DRS Technical deepdive (Volume 1) by Duncan Epping, VMware vSphere PowerCLI Reference: Automating vSphere Administration by Luc Dekens and Alan Renouf, andVMware ESX and ESXi in the Enterprise: Planning Deployment of Virtualization Servers (2nd Edition) by Edward Haletky; and many gadgets.
We know our attendees took their personal time mainly not Read more...
After preparing the event for almost two months, we are finally ready. If you join us onsite, here is direction to our venue. We have free food/drinks, and many books/gifts waiting for you, thanks to our sponsors and 12 volunteers.
If you join us online, we have a great news for you. Instead of WebEx, we will have a live broadcasting. Here is the URL: http://bit.ly/osvimeetup, courtesy of @lkilpatrick. You can enter as a Guest on 7PM (Pacific Time) for tech talks.
Here are the 8 tech talks we pulled together. A bit long but Read more...
While we in software industry debating which process to adopt for development, I found something in manufacturing very intriguing. On a recent article of Business Week The Case for Making It in the USA, it mentioned a GE factory in South Carolina where aircraft jet engines are made. What struck me is the following:
“Teams can adjust the line operation as they see fit to remove bottlenecks and maximize productivity. Recently, two teams came up with different ways to speed up the washing of turbine blades. The plant leader, rather than picking one way as the winner, approved buying equipment for each team to wash the blades its own way.“
Yesterday the VMware community noticed that the direct ESX download links were removed from vSphere download page. When I checked the download page, the ESX link is not with the bundles but at the end of the page in its own section.
To my own curiosity, I wonder what the adoption ratio of these two hypervisors is today. As an engineer, I don’t have sales data in front of me. Even I have, I am sure if I can share it here.
It’s been a while since I checked the VI Java API fling at VMware Lab last time. When I checked it again yesterday, I found something new and exciting – VI Java API on Google Android. The following comment was posted there by a gentleman called Bob:
Great framework, I used it on a recently published android application (avmcontrol – vsphere client for android), I had to tweak it a bit, however developing for android using vijava was much easier then the same for iOS4 devices.
You may be wondering why anyone would do this. This is in fact not a typical use case. You probably know that vSphere Client does not treat license keys like passwords which are not visually displayed as dots or asterisks. As a result, anyone who can access a vSphere Client can write down license keys and use them elsewhere.
Normally this is not an issue at all. What about Read more...
A new feature called vCenter Linked Mode has been introduced in vSphere 4. It allows several vCenter servers to form a linked mode group. When you connect to any of the vCenter server via vSphere Client, you see all of them behind a single pane of glass.
I got questions from time to time, “what does it mean for vSphere API?” More specifically, if you connect to one vCenter in a linked mode group, will you “see” all of them? If not, how can vSphere Client achieve that? Read more...
