The report also states that 64.1 percent of developers worldwide are rethinking some key aspects of mobile development in light of revelations of widespread digital surveillance by the U.S. National Security Agency. But in the United States, 43 percent said they would have no change in their development practices as a result of the revelations. Just 20.2 percent of U.S developers surveyed are considering more rigorous data encryption while 21.5 percent reported being more wary of public cloud. Also, 15.2 percent are more rigorous about secure coding.
"Developers are looking at it and saying yep, it's a problem but it's not a huge deal to us," King said. Appcelerator had expected the NSA impact to be much greater.
Mobile development, meanwhile, is straining traditional three-tier Web architectures that have included layers for data source, SOA/middleware, and client. The report said 34.7 percent of respondents found existing three-tier infrastructures inadequate for mobile demands. While these architectures have leveraged data payloads based on SOAP and XML, mobile really needs REST or JSON, King said. Appcelerator recommends a mobile-optimized infrastructure leveraging data optimization, payload transformation, synchronization/offline access, and orchestration of multiple data sources.
In other findings, the report said the watchword for mobile development now is "scale." A number of response statistics point out expectations and complexities with scaling the delivery of mobile applications. Rising ubiquity of applications is driving demands for scale. Nearly half of all respondents report application release frequency as monthly or faster, while 81 percent build applications to run on at least two mobile OSes.
