Introduction to the vSphere SDK (VI SDK) in Java and C#

ddeeths — Fri, 17 Jul 2009 14:33:12 GMT

We wanted to let you know we ran a very successful vSphere SDK lab at [Partner Exchange / Tech Exchange a few weeks ago in Orlando. For those of you who missed the event, I'm posting the manuals and code files. Going through the lab is a great way to get started with the API and includes handy sample code for modification or inclusion in your own programs.

The lab covers both the Java and C# versions of the VI SDK and uses the vSphere Web Services SDK 4.0 (formerly VI SDK 4.0). Though the lab doesn't cover any vSphere-specific features, I haven't tested it with VI SDK 2.5 and it will probably require some minor modification. For scripters that would prefer an introduction to the vSphere Perl SDK (formerly the VI Perl Toolkit) or the vSphere PowerCLI (formerly VI Toolkit for Windows), I posted a similar lab for those in an earlier blog post.

Exercises cover all the basics for using the SDK:
* Understanding managed objects and data objects
* Connecting to the VI API webservice
* getting the properties of managed objects using the PropertyCollector
* Using the SearchIndex
* Finding objects using TraversalSpecs
* Finding objects based on arbitrary criteria
* Collecting properties of multiple objects at the same time
* Understanding performance differences in some basic property collection strategies
* Monitoring properties for changes
* Monitoring tasks for completion
* Gathering performance statistics

There's obviously a lot more to do in the SDK, but once you've mastered those basic skills, most of the rest of the SDK is just an extension of what you already know. The exercises on collecting multiple objects properties at the same time and understanding performance differences due to property collector strategies cover some common problems I see with the management ecosystem partners I handle and are a great review for anyone trying to make sure their SDK code scales well.

A few things to note: I didn't update the doc with the new names of the various API components... I wrote the lab while those names were still under development. Also, I want to thank the other folks who helped put this lab together: Balaji Parimi (who wrote the Java code), Rajesh Kamal (who wrote the C# code), Alton Yu, John Kennedy, Paul Vasquez, and Steve Jin.

While most of the code handles errors gracefully and follows best practices, I’d like to point out that the code here is designed to teach concepts, not to be “enterprise ready”.

Its official - VMware Developer Day @ VMworld 2009 SF CA - event dedicated to software developers

heyitspablo — Thu, 09 Jul 2009 14:28:09 GMT

Folks,

Just wanted to clarify - event will be held in the Moscone Center in SF and not the Cal Academy of Sciences ;( I put this picture here because i think it would be a nice place to visit for anyone that is traveling from out of town - but I do agree this would be a SUPERB venue for a Developer Day.

Please save the date for VMware's first Developer Day @ VMworld 2009 - Monday August 31, 2009 in San Francisco CA.

We will be publishing session and registration information in a couple of weeks, but can provide some general information.

o 1 Day event dedicated for software developers building solutions for the VMware platform

o TAP membership is not required, or purchase of full VMworld Conference Pass

o There will be a Tech Exchange - TAP Track for Product Roadmaps (NDA - TAP membership required to attend)

o Sessions will range from vSphere SDKs to vCloud APIs - please stay tuned for session updates

o We will have plenty of demos and opportunity to meet with our R&D teams

Wanted to thank the community for your support and please keep the feedback coming. If you have ideas on what you would like to see please let us know and look forward to meeting the community members.

Nice picture below of the California Academy of Sciences - great destination for anyone that has not visited. They also have a great restaurant and Bar. My house is the little one under the television tower on the hillside - (which might explain my sense of humor and hair loss

VMware Corporate Icons - Really nice icons for you to use in your PPT ;)

heyitspablo — Thu, 26 Mar 2009 00:09:16 GMT

VMware Developer Spotlight - Andrew Kutz: Valued Community Member

heyitspablo — Sat, 05 Apr 2008 06:20:00 GMT

VMware Developer Center Blog - Developer Spotlight April 4th, 2008

I had an opportunity to meet with Andrew Kutz and wanted to share this conversation with folks out there that might be curious on who the person is behind the great contributions he has provided to the VMware Developer Community.

Andrew: First of all, thank you for this honor. The VMware online communities are for me the most professional and helpful forums I have ever had the opportunity to be a part of, and to be singled out amongst the long list of brilliant participants is an experience I will not soon forget.

Pablo: Tell us about your programming background and work experience?

Andrew: Short Version : I'm a geek whose had the privilege of working in a variety of odd jobs (from a boat valet to a Senate Paige) and Programming languages (from C to C#) for the last decade, transforming me into somewhat of a mutt, just like my baby boy Scruffy who is pictured with me above. I guess I fit the old cliche, "Jack of all trades ...". I don't really qualify for the "wearer of many hats"description since those who have met me know that I pretty much only wear my gray fedora, and that's it : )

Long Version: A lot of people are a bit taken a back by my area of study in college -- my degree is in Ancient History and Classic Civilization, so I do not have the same structured background as a lot of the developers you may meet. While some individuals look at my resume and deduct a point from their opinion of me, I've never looked at my chosen educational path as a negative, rather I think it taught me a whole separate area of critical thinking that a lot of programmers are missing these days. Truth be told my intent was to pursue a career in law, but I married soon after graduating college and my number one priority became helping my Mandy finish her graduate career in the history department at the University of Texas at Austin (UT).

Despite my penchant to disappear at parties only to be found upstairs participating in a mad orgy of Latin and Greek oration, I have actually been hacking out code since the days of Q-Basic and Nibbles.I suppose my professional programming career began when I worked at the American Crane & Equipment Cooperation (ACECO) and then went into hibernation once I began attending college where I worked several very non- technical jobs (albeit still geeky): a music geek at Tower Records on the Drag, a political geek as a paige at the State of Texas Senate, and even a car and boat geek as a valet for a lake-side restaurant. Eventually I ended up working for the UT Academic Computing and Instructional Technology Services (ACITS) Help-desk. From the help- desk I moved to the NT group that became the Windows Enterprise Services (WES) group. I stayed put for another 7 years in which time I cranked out a bunch of random code that somehow managed to function as Sudo for Windows (Sudowin), Exchange resource schedulers,Mainframe-to- Active Directory account synchronization web services, and they even let me manage a few servers(Terminal, Web)!I also helped create the first central-IT virtualization solution at UT using VMware ESX 2 and VirtualCenter. Just as the virtual infrastructure was getting off the ground I did something silly and left UT to pursue an Analyst position with the Burton Group. After 6 months I learned that the life of the analyst was not for me (too hands off), and I returned to UT as a member of the Information Technology Services (ITS) Applications group where I am currently abusing my on-the-clock time to respond to these questions! : )

Oh yeah, just because my editors would be a little peeved if I didn't mention it, I also write for SearchServerVirtualization, SearchVMware, andSearchEnterpriseLinux.TechTarget.com. So, you know, check them out! : )

Pablo: Tell us about any recent or cool projects you are working with using the VMware SDKs ?

Andrew: (All code mentioned is freely available under the New BSD license)Sure thing! FYI - all of the current VMware-related code I am working on is FREELY available or linked from http://www.lostcreations.com/code/wiki/vmware/

. Definitely one of the cooler things I am working on is Monét.Monét exports VI logs to a syslog or Windows event log server. I wrote it in part to help other developers understand basic ideas about VI SDK development, and since it is implemented in C#, Java, and Perl, it is a great way to see how to transition between the different languages
that are available to leverage the VI SDK. About a month ago I managed to get lucky with Lutz's Reflector and figured out how the internal plugin architecture of the VI client is
put together and released the SVMotion plugin. Since then I released a PDF that explains the VI plugin architecture and hopefully shows other developers how to create plugins (I apologize if it doesn't make sense, I wrote most of it while trying to keep track of the
goings-on of 4 dachshunds). In an effort to recapture some hosting costs I started VIPlugins.com for the sole purpose of injecting some Google ad placements (j/k). So far I've had +12,000 downloads of the PDF and various plugins and no click-throughs -- sigh. Two of the cooler plugins are Invoke, which lets you invoke third-party applications from within the VI client using the currently authenticated session cookie and 37migrations. The 37migrations plugin works in conjunction with 37migrations.com to plot VMotion events across the world.Basically I was looking for an excuse to play with the Google Maps APIs : )

I also started work on ivi - the Java Virtual Interface (sorry, that's my Latin showing --J's looked like I's back in the day -- wayyy back).ivi is an attempt at creating an OS-agnostic management application for VMware VI, Xen, KVM, and OpenVZ. ivi attaches to the aforementioned virtualization solutions using the VI SDK, the XenAPI, and lib-virt. So far ivi can connect to VI and Xen and list their contents. Once I get lib-virt to compile and function (the latter is the hard part) on my Mac I will include support for KVM and OpenVZ. I know the project is in alpha stage, and while the milestone of listing contents seems simple, the project is more about creating an abstract plugin architecture for accessing multiple virtualization solutions than actually producing a marketable product. Again, the code for ivi is OPEN and FREE.

Some ideas swirling around in the mess that is my mind include:

- - Implementing the Cisco IOS commands for the ESX virtual switch infrastructure using Perl? Maybe? Dunno yet...

- - A free and open implementation of VirtualCenter called OpenVirtualizationManager in order to help reduce the cost of a VMware Infrastructure.

- - A role-playing game at VMWarpg.com that uses stats from your VI installations to generate stats for your avatars, and you battle for territory on Google maps. Think D&D meets Risk.

- - A version of the VI client written with the Google Web Toolkit called Aianteia (cooming soon).

Some people may ask, "Aren't you worried about showing your hand?" Not really, if you want to take any of these ideas and run with them, please do so. I just ask that if you need help that you ask me as I'd love to be involved. I'm just in it for the fun. It was for the groupies, but turns out that virtualization groupies, yeah, not so much. : )

Pablo: How long have you been using the VMware SDKs and what has been your experience using them ?

Andrew: I have been using the VMware SDKs since the summer of 2006 when I started playing around with the VI SDK in order to automate the creation of port groups. I parlayed that experience into a series of articles forSearchServerVirtualization.TechTarget.com called "Leveraging the VI SDK with .NET" that have apparently remained high- traffic articles to this day (It's got to be because of spiders, certainly not readers!) : ) Anyway, I've been hooked for developing for VMware and other virtualization solutions ever since.

Pablo: What would you like to see from VMware in terms of SDK / API functionality ?

Andrew: I would LOVE to see the equivalent of the VI Perl Toolkit for C# and Java. I now understand that the odd nature of the SDK (a reference for one and all!) is simply due to the nature of SOAP, but it does not make it any less aggravating to deal with. I have played with the C# toolkit that VMware uses internally and it is sooo smooth. Smooth like a line of Aaron Sorkin's dialogue smooth. We're talking triple-blade action smooth. You get the idea.

I would also like to see a unified SDK. In terms of Java:

com.vmware.vim
com.vmware.workstation
com.vmware.fusion
com.vmware.server

And the all important:

com.vmware.common
com.vmware.virtualmachine

The last one would be really nice in order to tie together common VM properties and such. Of course, this would have to be a public- facing SDK that VMware wasn't married to for revision purposes, but it would still be nice from a developer point-of-view to have
VM-management code work regardless of the intended product or platform. Of course, this is probably made difficult by the generational differences between all of VMware's products, but a boy can dream, no?

Pablo: Any tips for developers out there new to the VMware SDKs ?

Andrew: Certainly they should use the VMware Developer's Center! Us "old- timers" did not have access to such a luxury back in the "day" (umm, last year!), so anyone new to VMware development should certainly take advantage of VMware's new commitment to its development communities.Also, you can always e-mail me. I'm always happy to help out when I can.

In a previous Spotlight, Tom Milner related some sage advice that I would like to repeat -- "What do you want to do with it?" Tom, I could not agree more. Too many developers see a problem and create a solution. That works, but you usually end up with a fairly boring solution. I like to throw caution to the wind and come up with the idea of a solution, and then build the pieces that it takes to get there. At Austin's SXSW festival this year, Apple engineer Michael Loop shared with audience members Apple's design process(http://www.businessweek.com/the_thread/techbeat/archives/2008/03/apples_desi gn_p.html?campaign_id=rss_blog_techbeat). Basically, Apple approaches its design process much like a car designer or a fashion mogul - they design the fantastic and then look for the kernel of truth in their design and work backwards in order to turn truth into reality.

VMware developers should seek the truth in order to create solutions that are beautiful, fun, and fantastic.

Welcome to the VMware Developer Center Blog

Atami Beach, San Salvador

Hello,

Welcome the VMware Developer Center Blog. My name is Pablo Roesch and I am the Product Marketing Manager for the VMware Infrastructure SDKs. My job at VMware is to help empower developers, IT administrators when integrating, and automating with our SDKs.

Before VMware I worked for Sun Microsystems in various roles, most recently responsible for building out the Developer Services Portfolio for the Sun Developer Network. On the personal side I have lived in San Francisco most of my life, and enjoy spending time with my wife and kids. Just in case you are ever in this fine city I would recommend the Slanted Door for dinner and CafeGreco for an after dinner Cappuccino. As a side note I have included a photo of my all time favorite beach in San Salvador which helps me put things into perspective.

It is an exciting time for us at VMware as our SDKs are going through a much needed evolution with recent release of the VI Perl Toolkit 1.5 and upcoming sneak peak of the VI Toolkit for Windows (manage VI using Powershell)

I often get asked what the difference is between the VMware Developer Center and the Developer Community so thought I would bring this up front.

The VMware Developer Center provides information on latest SDK product downloads, knowledge base articles, webinars, questions and answers as expressed by VMware. The Developer Community is how the community interacts with VMware. The VMware Community is where developers, scripters post questions about our SDKs, provide sample code for community use, and comments on our products.

Visit our VMware Developer Center http://vmware.com/developer as we have recently made some much needed improvements to hope you find them helpful.

Navigation: Created a new navigational bar on right hand side, which will help with navigation of our site.

Knowledge Base Articles: Growing list of KB articles, to see current list click here

SDK Questions and Answers: Adding list of frequently asked questions

New webinars and sessions: New sessions posted range Product information to VMworld Sessions.

VMware Sample Code: Ongoing effort to increase our code sample library as requested by our users. Comment or suggestion for Sample Code? Please let us know by answering this quick questionnaire.

We look forward to continuing improvements to our site, please keep the feedback coming !
