DoubleCloud => Private Cloud + Public Cloud

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.

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.

From high level, automation is the opposite to  Read more...

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, and VMware 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.“

I would say it’s pretty  Read more...

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.

Instead, I tried  Read more...

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.

Following the link, I found  Read more...

Days ago I introduced the new licensing APIs since vSphere 4 and a sample that prints license expiration dates. Here is yet another sample that replaces an old license with a new license.

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...

In my previous blog, I introduced the new licensing APIs since vSphere 4. As promised, I will write samples showing how to use the APIs.

Here is the first sample (stay tuned to next one, coming soon). What it does is to check the licenses in vCenter server for their expiration dates, and print them out in the console. You can of course save them into other format, say an CSV file so that you can use Excel to further analyze it. To run the sample, you must change the IP address to the vCenter server, the username/password, as would with most VI Java API samples.

Note that a license could be an  Read more...

I always believe cloud computing is a computing, not the computing of the future. Its elastic and centralized nature allows greater level of sharing that was otherwise impossible within single organizations. It works great for anyone who has dramatic workloads and other cases. But it doesn’t work in all the cases.

Recently a new use case comes to my attention. It actually requires opposite way to cloud computing. You may have known recent developments in bioinformatics. With human genes are sequenced and analyzed, we can  Read more...

There has been a total change in vSphere licensing model since version 4. Before that, you need a special/dedicated licensing server which may be more flexible/powerful but also cause many troubles in production environment which made licensing related issues one of the top categories in tech support.

vSphere 4 has dramatically simplified the whole licensing model, and removed the licensing server. To find out how the new licensing model works, check out the VMware vSphere 4 Licensing Guide. It covers both the vSphere side and the portal with which you can easily manage your license keys: splitting/combining, etc. This article does not cover the portal part but related APIs only.

Management APIs reflect product features. If you check the latest API reference, you will find out  Read more...
