The study examines usage across programming languages, frontend technologies, databases/storage/caching, mobile technologies, infrastructure, DevOps, API integration, advanced technologies, and big‑data software.

Programming Languages

JavaScript/Node.js, Ruby on Rails, and Java are widely used across all company tiers. Python is favored by higher‑performing firms, while PHP is more common among lower‑performing ones.

Frontend Technologies

Beyond the popular Ruby on Rails, HTML5 and CSS see extensive adoption. The Bootstrap framework is less used by better‑performing companies.

Database/Storage/Cache

MySQL, MongoDB, and PostgreSQL dominate the database landscape, while SQL Server and Oracle see far less usage.

Mobile Technologies

iOS is slightly more popular than Android, and higher‑performing companies tend to adopt iOS more, whereas Windows Mobile is negligible.

Infrastructure/Hosting

AWS and Heroku lead the market; superior companies prefer IaaS solutions like AWS over PaaS options such as Parse, likely due to greater technical capability and customization needs.

DevOps Tools

Besides Chef, Docker and Puppet enjoy high popularity, while other tools vary in adoption across company tiers.

Search Technology

Elastic Search is the most popular search solution.

API Integration

Facebook API is the leading API integration choice.

Advanced Technologies

Big data and machine learning have become widely adopted by technology companies.

Big Data Software

Hadoop is the most popular big‑data software.
