Integrating VIX API into vSphere API is a great decision VMware made for its vSphere 5.0 release. Instead of working on two separate APIs, you now have one to deal with. It also solves the portability issue of VIX APIs which is tied to a specific platform – VIX has three versions for Windows, 32-bit Linux, and 64-bit Linux.
Thanks to John Troyer and VMware community managers, I successfully changed my email for login with the community recently. During this long weekend I spent a little time checking out the developer community.
I found that the static contents out there are largely outdated. In my estimation, it hasn’t been actively maintained for more than one year. Listing outdated contents not only confuses the community, but also lets go a great opportunity to educate and influence developers.
Today is the last day of VMware Partner Exchange 2012. There’s no keynote, therefore I went directly to breakout sessions.
The first one I attended was “SRM 5.0 and vSphere Replication – Understanding the Use Cases and Implementation Options.” The SRM used to manage the storage array that actually replicate LUNs to pair arrays in remote sites. This results in a restriction that the storage arrays must be compatible, which means they must come from same vendor and probably same model. When I was at VMware, I helped several partners with their storage array adapters for SRM. With vSphere replication, the replication happens at higher level thus the restriction goes away. Coming with the flexibility is slightly slower performance. Like anything else, you simply cannot have all the best but you can apply right technology for certain use case, for example, use vSphere replication for ROBO (remote office, branch office) use case.
Same as yesterday, the conference started with keynotes. The first one was by Carl Eschenbach, VMware Co-President of Customer Operations, followed by a motivational keynote by Bill Taylor, founding editor of Fast Company Magazine. As a technical professional, I always try my best to get more business insights and perspectives therefore I attend business related keynotes whenever possible.
Today is the first day of VMware Partner Exchange 2012 in Las Vegas. As usual, it started with keynotes, presented by Scott Aronson (Senior Vice President, Global Channels and Alliances), Paul Maritz (CEO), and Steve Herrod (CTO & SVP, R&D) consecutively. I personally didn’t find a lot new but mostly rehashed from previous keynotes. Nevertheless, there were several interesting numbers from the three keynotes:
- $41.5 billion: private cloud opportunity by 2015.
- 350,000: VMware customer base.
Today I read an interesting article “The Efficiency Paradox” in latest Business Week magazine. It reviews the book Conundrum: How Scientific Innovation, Increased Efficiency, and Good Intention Can Make Our Energy and Climate Problem Worse by David Owen. I haven’t read the book but got the main idea of the book from the article.
As John F. Kennedy put it, “everything changes but change itself.” This is particularly true in computer industry where things move faster than other industries. It’s further complicated when you also have dependencies that also move fast.
A good example is that your software project depends on another product which is also under development. Sometimes we call it synchronous development. The payoff could be huge if you can ship your product at the same time as the dependent product which presumably has bigger user base. You can then leverage the go-to market opportunity as first player in the bigger community.
The first part of the title of this article may seem like mathematics, but it’s really not. This is just about software packaging – a topic not so often discussed. In plain English, it basically says something like: one application with N features vs. N applications, each of which has one feature. More generally speaking, it can describe software entity with sub-elements. I will discuss it in the contexts of mobile/desktop, and virtual/physical.
As I tweeted last week, there would be a big announcement when the open source VI Java API gets 20,000 downloads. It hit target yesterday. To celebrate it, I decide to release the code generator for the API, which William (@lamw) rated as “awesome.”
While installing and configuring vCloud Director recently, I kept thinking how to simplify it by removing un-necessary concepts and steps. To be fair, vCloud Director as of version 1.5 does a decent job to provide a high level abstraction for cloud infrastructure. Still it can be significantly improved just like every other new technology. Note that I pick vCloud Director as an example for the following discussion simply because VMware is the leader in virtualization space and what it does has ripple effects on other vendors.
As I predicted for 2011, the cloud will be the ultimate powerhouse for mobile devices. The reason is simple: although fancy and stylish, the mobile devices typically do not have enough computing power and storage space for certain applications.
If you’ve had a chance to use vSphere Web Service SDK, you must know the PropertyCollector is very hard to use. It takes a newcomer quite some time to learn how to use it, and even more time to learn to use it effectively. Luckily, you no longer have to if you use the open source vSphere Java API (a.k.a. vijava) because it has encapsulated the PropertyCollector behind these newly added getter methods of the managed object types.
I went to EMC office at Milford, MA last week for a 5 day training class on Vblock Administration. As you may have known, VCE Vblock is the industry’s first and leading converged infrastructure with compute, network, and storage from industry leaders. For the compute, it uses Cisco UCS. If you have followed my blog, you should know that I have blogged about the UCS emulator and XML management APIs.
While checking out the search engine terms to my blog, I found an interesting one there: “why so many programming languages?” A great question indeed. If you take a look at the Wikipedia page on programming languages, you will be surprised by the number of programming languages today. To give you a hint, the languages are categorized into different sections by their first letters. When I browsed the page, I found most of them were new to me and will definitely remain so in the future.
IT automation is key to IT efficiency, agility and control. Here are some of my recent thoughts on this topic. Please feel free to share yours.
People and Automation
- All automations ultimately start from people, not the other way around.
- Although automation has a role, it never takes the place of a good system administrator.
- Not everything can be automated, and not everything is worth being automated.
After finishing up my reflection of 2011 predictions , it’s time to make my predictions for 2012 as today is the last day of 2011.
1. Virtualization war will be heated between VMware and Microsoft. The trigger will be the Hyper-V 3.0 which is expected to ship in the middle of 2012 with the Windows 8 server. According to many people, the 3.0 release will bring it on par or better than latest VMware hypervisor.
Last December I made top 5 predictions on cloud computing for 2011. When the year ends soon, it’s time to review them. I won’t rate their accuracy myself because I am indeed biased. You are welcome to do so in the comments though.
“1. The focus of cloud computing will gradually shift from IaaS to PaaS which becomes key differentiator in competition. Developer enablement becomes more important than ever in ecosystem evangelism, full software lifecycle integration, IDE support, API and framework, and etc.”
Even if you haven’t heard about BusyBox, you may have used it. It runs in every ESXi, which doesn’t have a full OS as console like classic ESX. Still, you need an easy way to interact the hypervisor directly. So the ESXi includes a tiny console that uses BusyBox (reduced version) due to its small size.
The BusyBox has been ported to Windows as well. You can download the 600+K executable here. It’s really a simple exe file and you can place it anywhere.
DSL is an overloaded acronym standing for many different things. I first knew it as Digital Subscriber Line for Internet connection, and then Domain Specific Language. Recently I learnt a new one: Damn Small Linux. As you see the word small, you may think it’s for embedded system. It’s not.
This week I spent some time deploying a Web application I developed using Microsoft Visual Web Developer 2010 Express (it’s free). For that, I installed Microsoft Internet Information Service (IIS) on my Windows 7 enterprise edition. This turned out pretty straight-forward: Control Panel – Programs – Turn Windows Features on or off. In the Windows Features dialog box, just locate the Internet Information Service and check on it. After a click on the OK button, the IIS (version/build is IIS 7.5.7600.16385) was installed.
