Market Sizing the Computing Cloud

When looking at the Computing Cloud from a market perspective a number of very obvious questions start to arise. How big is the computing cloud? How many companies are in the cloud. How much revenue is actually being generated by the Computing Cloud, who is actually buying Cloud services and most importantly what is the Growth and opportunity within the Computing Cloud?

My gut tells me that the Computing Cloud very well might be another disruptive technology. A game changer that transforms how applications and services are delivered to the market. But good companies don't make decisions based on a gut feels, they make them based on business models that promise a strong return on investment.

Many companies are looking at the Computing Cloud as a way of reducing costs and delivering core services to market faster. However some companies are looking at the Computing Cloud as a new market itself. Companies like Google, Microsoft, Amazon, eBay and SaleForce.com are already in the market. Others like RightScale, who recently raised $4.5M in financing, are just now entering. How do these companies figure out what the Market opportunity is?

I have started to scan the web to try and see how much information is actually available on the topic so far. The results are pretty slim. Gartner, Forrester and the like might have some market data, but nothing that showed up on any of the public sites.

So far I have been able to find a few data points on Cloud Computing. There is a great site for registering all of the APIs available for Cloud Computing - programmableweb.com. The site not only lists all of the APIs available (755 as of this writing), but also lists the mashups that use these APIs. They also track the most used APIs, by category and vendor, by all of the Mashups. I took a couple of snapshots of the API usage and plotted it's 1 month growth, by category.

This chart tells us a few things. First off the most used APIs for mashups are mapping. This does make sense, as many web sites are now embedding maps and context sensitive location information. All one has to do is look at the proliferation of map information within Realty web sites to see this phenomena.

Second we can see that the second tier of mashups are using APIs for Photos, Shopping, Video and Search. These are all consumer related APIs, not enterprise related. Part of this is related to the nature of mashups and the source of our data. We are not likely to see corporate activity and usage patterns within this data set. However it is interesting to note that the sum of usage for Storage, Hosting, Identity, Office and Database is less than 1/3 of the total usage for Video and only 1/20th of Mapping.

The next chart shows us the number of mashups added during the period by Category. Again this shows us that Mapping is by far the leader. Widgets and Search also added 3 new mashups.

Summary
So what does this tell us? First off we have to realize that the data set is limited, and comes from a site very focused on mashups and the usage of APIs by those mashups. Even within that context it is obvious that Mapping is the big winner in the early use of Cloud Computing. This does make sense. There are a tremendous number of web-sites that can immediately benefit from embedding location sensitive maps directly onto their site. With the publication of easy to use map tools from companies like Google and Microsoft it is inevitable that sites would start to take advantage of them.

This trend should continue, and even accelerate. How long until every corporate web-site has an embedded Google map on their Corporate Location Page? Who is going to write their own video or photo management application when they can just embed that service onto their web site from a site like Flickr or YouTube.

The transition is now in full swing. Base services for mapping, photo management, video, advertising and other web-based services are becoming commodity applications delivered from a core set of providers. It will be left up to the rest of us to figure out how to use these services in unique and interesting ways.
