SOA and cloud by the numbers: what the data tells us so far

Ten data points show interest and caution toward SOA and cloud computing

There have been a lot of statistics floating around pertaining to SOA and cloud, and we've reported on a bunch of them here at this blogsite. Here, for your at-a-glance reference, is a summary of service-oriented surveys and research we've seen in recent months:

Ninety-two percent of companies say their SOA initiatives met or exceeded business unit objectives, while only eight percent say they did not. CA released the results of a survey that explored SOA failure, and who takes charge. The survey, which covered 615 companies in the process of SOA-based efforts, actually found scant evidence of widespread SOA failures. The survey also included an "SOA Pain Scale" that is self-explanatory.

Percentage of companies using SOAP dropped from 54% in 2008 to 42% in 2009. The number primarily using or considering REST-based Web services is predicted to grow by a proportional amount, from 14% to 24% over the same time frame. The ground under SOA — long solid SOAP territory — appears to be shifting to more lightweight service approaches. A new survey of 270 business professionals, just released by InformationWeek, finds that one out of four have moved into service oriented architecture, and many are opting more lightweight approaches such as REST over SOAP.

About 13% of large enterprises and 10% of small to medium-size companies have adopted cloud-computing-based applications. A survey from the SHARE users group (large IBM system users) also finds a strong link between cloud computing and other virtualization strategies, to the point where cloud computing is a logical extension of more advanced internal virtualization efforts.

SOA market growing 17% a year; to reach $10 billion by 2015. Wintergreen Research undertook the almost impossible task of attempting to measure the SOA market (where does it begin and end? Middleware? Applications?  Tools?). The group released a six-year forecast of the SOA infrastructure industry, calculating that the market will grow to from the current $3.3 billion to $10.3 billion by 2015.

Forty percent of companies with SOA-based methodologies do not measure the time to achieve return on investment for their SOA efforts. A Gartner survey finds about half of the non-adopters say they haven’t moved to SOA “because they cannot articulate and demonstrate the business value of it.”

Only one percent have negative experience with SOA to the point they would put the kibosh on it. A Forrester Research survey of 2,227 IT executives finds that only one percent of current SOA adopters say they have received little or no benefit from the methodology — that’s right, only one percent. Sixty percent said they have seen some benefits.

New IT initiatives on Wall Street include enhancing electronic trading tools (69%), improving data capacity and bandwidth (58%), and improving technology framework and infrastructure (58%). A survey released by IBM and Securities Industry and Financial Markets Association finds Wall Street cleaning up its act with projects that involve SOA.

Forty-nine percent of enterprise developers expect to deploy apps in a private cloud environment sometime over the coming year. An Evans Data survey of 500 developers finds enthusiasm for the cloud, but also  plenty of concern about security and reliability.

About 33% of companies now employ enterprise mashups. Business Insights estimates the enterprise mashup market, worth around $161 million in 2008, will expand more than tenfold to $1.74 billion by 2013 -- fueled by SOA.

Number of companies planning for cloud computing tripled in nine-months' time. A survey from Avanade shows a 320% increase in respondents reporting that they are testing or planning to implement cloud computing. The study also found that while companies are moving toward cloud computing, there is little support for cloud-only models (just five percent of respondents utilize only cloud computing). Rather, most companies are using a combination of cloud and internally owned systems, or hybrid approach.
