An Update on Microsoft’s New Casablanca Release

A little over a month ago I wrote a post entitled, “Microsoft’s New Casablanca Release” about Microsoft’s newest Casablanca product. Niklas Gustafsson, a member of the Microsoft Visual C++ Team was kind enough to contact me and answer a few questions about this release. I decided that you also need to know the answers to these questions so that you can make an intelligent decision about Casablanca. As a quick recap, Casablanca is a new product that lets C++ developers interact with the cloud using REST.

The first thing Niklas pointed out is that Casablanca isn’t precisely a product—it’s what is termed as an incubation effort, something to see what is possible and will work. Casablanca is early in its life cycle and doesn’t provide either the quality or maturity that a released product would provide. to me, this means that you need to be careful using Casablanca. For the time being, it’s probably an interesting technology to play with, but you probably shouldn’t employ it in your production application because it will change quite a lot.

Even though I use C++ for utilities and low level program (as described in C++ All-In-One Desk Reference For Dummies), Niklas pointed out that many organizations use C++ for larger, line of business applications. In many cases, the reason for using a language like C++ for this purpose is that the organization has already made an investment in C++, so the language is familiar and the organization already has the required resources. I still can’t imagine creating a large scale user application using C++, but I’m also not the one trying to forge ahead in a large organization. It seems to me that using other languages would be simpler and less error prone, but I’m well-versed in using a number of languages, so I have the option of using the best tool for a specific task. In fact, Niklas summarized C++ usage for larger applications in the following points:


  • Raw performance
  • Portability
  • It’s what they know

To make his point clearer, Niklas provided me with a link to a whitepaper entitled “C++ and Cloud Computing” that makes a number of points clear. I encourage you to download this whitepaper and give it a read before you make any decisions regarding C++ and the cloud. It certainly helped me envision how someone might use Casablanca a bit better. For example, even a low-level application could need access to an online storage provider in order to access the information it needs. I also hadn’t considered some special areas of program, such as gaming, when I wrote my original post—I was thinking more along the lines of what a business developer would need.

With regard to my question about using REST, rather than SOAP, Niklas pointed out that REST currently enjoys far wider support than SOAP and that it’s simpler to implement. If Casablanca becomes a success, SOAP support could follow. So, at least the team is thinking about SOAP as a future addition.

It’s also important to remember that many organizations are only starting to think about cloud computing, so technologies such as Casablanca are still well ahead of the curve. Sometimes in reading the technical articles online, you get the idea that cloud computing is already well entrenched in the enterprise. The truth is that many enterprises are only now experimenting with the cloud and some will never use the cloud due to regulatory or other concerns.

I was really happy that Niklas took time out to contact me regarding Casablanca. I’ll be taking another look at this technology as the Visual C++ Team works on it and will likely provide you with an update sometime in the future. In the meantime, let me know how your organization is working in the cloud today at
