2 Introduction Research Objectives Research Report: Platform-as-a-service Language Use Study As part of ESG s application development and deployment (AD&D) research, this survey was primarily focused on understanding interest in platform-as-a-service (PaaS). There were 4 specific objectives in fielding this survey: 1. Quantify PaaS adoption 2. Understand the level of satisfaction with PaaS and why 3. Identify what PaaS features are most important to IT managers and developers 4. Examine what languages, frameworks, and development environments are most preferred by developers This report will examine the fourth objective: what languages are in use by developers who are either Paas users or evaluators. Other reports will examine PaaS adoption, satisfaction, and feature preference. ESG surveyed 326 IT professionals and application developers representing predominantly midmarket enterprise (100 to 999 employees) and large enterprise-class (1,000 employees or more) organizations in North America. The sample included 176 application developers and 150 IT managers. The language use questions in this survey were only administered to application developers. It also needs to be understood that the respondents to this survey are either PaaS users or PaaS evaluators. A PaaS user is an enterprise that currently uses a PaaS. A PaaS evaluator is an enterprise that currently does not use a PaaS but is actively evaluating a variety of PaaS products for intended use in the next 18 months. This means that the language use questions analyzed in this report reflect the behavior of enterprises that are either using PaaS or likely to use PaaS. We can speculate that enterprises committed to PaaS represent a more technologically savvy segment of the overall population of enterprises that engage in the development of custom applications. This language section of this survey was designed to answer the following language use questions: What client-side languages are in use for application development? What client-side platforms are used for application development? What server-side languages are in use for application development? What high productivity application development environments are in use? Survey participants represented a wide range of industries including manufacturing, financial services, health care, communications and media, retail, government, and business services. For more details, including how we screened respondents, please see the Research Methodology and Respondent Demographics sections of this report by The Enterprise Strategy Group, Inc.

3 Research Methodology To gather data for this report, ESG conducted a comprehensive online survey of IT professionals and application developers from private- and public-sector organizations in North America (United States and Canada) between October 28, 2014 and November 6, To qualify for this survey, respondents were required to be responsible for evaluating and/or selecting software application development and deployment tools for their organization. Respondents who were not involved in the decision making process for software application and development tools were disqualified. Respondents were also required to be 26 years old or older and have 2 or more years of experience working in an IT or application development role. If a respondent was under 26 years old or had less than 2 years work experience in an IT or application development role, they were disqualified. All respondents were provided an incentive to complete the survey in the form of cash awards and/or cash equivalents. After filtering out unqualified respondents, removing duplicate responses, and screening the remaining completed responses (on a number of criteria) for data integrity, we were left with a final total sample of 326 IT professionals and application developers who either were currently using PaaS or intended to use PaaS within the next 2 years. Please see the Respondent Demographics section of this report for more information on these respondents. Note: Totals in figures and tables throughout this report may not add up to 100% due to rounding. Language Categories Our choice of language categories recognizes both the significant difference between high control and high productivity environments as well as the growing specialization on clients and servers. Consequently, we chose to establish four language categories, which are as follows: Client-side Languages. Client-side languages are designed to address user interface development, promote dynamic application behavior, and communicate with servers. Client-side Frameworks and Platforms. Client-side frameworks are typically libraries that simplify the development of applications while providing a comprehensive set of features that enable more sophisticated application behavior. Client-side platforms are similar to frameworks but lean more in the direction of development tools, code libraries, and environments for building and managing client-side applications. Server-side Languages. Server-side languages fulfill a variety of roles including structuring static and dynamic pages for delivery to the client, enabling the development of application business logic, and reading/writing data from/to back-end databases and content repositories. High Productivity Development Environments. High productivity development environments (HPDEs) are intended to provide developers with tools that are optimized for the development of application business logic (BPM tools) or provide a unified environment for developing all aspects of a modern N-tier application. These tools are generally very visual and provide pre-built constructs for common activities, thereby simplifying and shortening the application development process. Language Analysis The language section of this survey was administered after all of the primary screening questions and demographic questions were answered. This ensured that application development professionals answering the language questions met all of the criteria in order to qualify for this survey. Our approach to analyzing language use was designed to address several objectives. The first objective was to identify the primary languages, frameworks, and development environments in use. The second objective was to understand other languages, frameworks, and development environments in use. We accomplished these two goals by asking the developer in each language question to identify the primary, secondary, and tertiary tools in use at their enterprise.
4 Research Report: Platform-as-a-Service Usage and Satisfaction Study 2 In our analysis of the language data, we evaluated the data in its raw form and also after weighting the data. We weighted the data by assigning points for each position. The weighting scheme we used was as follows: Primary selection: 25 points. Secondary selection: 18 points. Tertiary selection: 15 points. This weighting scheme was designed to recognize the importance of the primary selection but avoid being unduly punitive with respect to the secondary and tertiary selections. A comparison of weighted results to unweighted results shows no difference in the stack ranking of the leading products in use. We are presenting the weighted data in this report because we feel it better reflects the stature of products in use at enterprises. Language by Frequency of Use Calculations The frequency of use percentages for the language data were calculated by first weighting the primary, secondary, and tertiary selections of each respondent. These weighted scores were then summed across all respondents. The percentage value for each language selection (primary, secondary, or tertiary) was then calculated by taking the weighted value for the language selection and dividing it into the total weighted score across all language selections. This approach enables frequency of use data for languages to also be interpreted as penetration rate data by language. Language by Age Category Calculations Language use by age category percentages were also approached using weighted language data. However, since the number of respondents in each age category varied, the weighted value for each language was divided into the weighted total across all languages by age category. This approach allows penetration rates for a particular language to be compared across age categories.
