What’s New in vSphere 5.1 SDK and APIs

I know it’s well past the GA date of the product on September 10, but I still decide to write this what’s new for the completeness of vSphere SDK FAQs.

As I always emphasize, the SDK/APIs are “view” to the product (you can think it as “model” here). Therefore to understand a SDK/APIs, it’s important to check out the product first. No exception for the new features: what’s new in vSphere decides what’s new in vSphere SDK/APIs. For that, you want to check out the What’s New in VMware vSphere 5.1 at VMware website.

VMware vSphere SDK with Visual Studio 2012

While trying latest Microsoft Visual Studio 2012 Express, I also played with the C# samples of the VMware vSphere SDK. Unfortunately, there isn’t direct support for VS 2012 but for VS 2010, 2008, and 2005. However, you can easily create project files for the VS 2012 by yourself assuming you are already familiar with the Visual Studio environment.

The Fifth Bread and the Mobile Computing

Once upon a time, there was a gentleman who was very hungry. He bought 5 breads. After finishing the first 4 breads, he still felt hungry. While eating the 5th bread, he found himself full. Then he thought it’s the fifth bread that made him full, and wondered why he had wasted money on the first 4 breads.

A Quick Hack With vSphere Web Client Timeout

Last week I released a tiny tool called DoubleCloud Client, which eases the usage of vSphere Web Client. I didn’t have time to add another hack which can bypass the session timeout of vSphere Web Client.

By default, vSphere Web Client times out after 30 minutes of inactivity according to VMware Doc. After timing out, you got to re-login and click back to the page you left out. It’s good for the security, but also not convenient. If you use it on your own desktop and have set up screen saver with password protection, you don’t really need this security feature.

Hadoop MapReduce Data Flow

As its name suggests, the Hadoop MapReduce include Map and Reduce in its processing data flow. At its highest level, the MapReduce follows the traditional wisdom “Divide and Conquer” – dividing big data to small data that can be processed by a commodity computer and then pulling the results together.

A Tiny Tool to Ease the Use of VMware vSphere Web Client

In my previous article, I talked about why Web is not a good choice as the primary GUI for vSphere. I also mentioned that I was working on Ua small app to enhance the user experience of vSphere Web Client.

Today I am happy to announce a small application I developed recently using latest Visual Studio 2012 Express which is free from Microsoft. Although known with my work on Java in the community, I am pretty open to any programming languages and tools that are best to get work done. This time it happens to be C# and .NET. :-)

Why Web is Not Good as Primary GUI for vSphere

I recently started to use the new Flex based vSphere Web Client while working on the open source vijava to support vSphere 5.1. Overall I like the look and feel, and particularly the extensibility story around the new architecture. However, I am not impressed by the performance – I saw way more “loading…” and clock cursor than I expected. Technically, I don’t think that is the direction VMware wants to bet on as the primary user interface for its flagship product vSphere.

Defining Software Defined Data Centers

After VMware touting out the new term “software defined data center,” I suddenly saw many vendors claiming they support software defined data center at VMworld. Days ago I read a news about Joe Tucci, the CEO of VMware’s parent company EMC, explaining what “software defined data center” is.

Hadoop File System APIs

As mentioned in my previous post on Hadoop File System commands, the commands are built on top of the HDFS APIs. These APIs are defined in the org.apache.hadoop.fs package, including several interfaces and over 20 classes, enums, and exceptions (the number of interfaces and classes varied from release to release).

As always, it’s best to start with a sample code while learning new APIs. The following sample copies a file from local file system to HDFS.
