This study investigated DevOps practices and experiences in the South African software development context, along with associated perceptions of benefits and challenges. Survey data collected from a sample of 80 software development professionals showed that more frequent builds, earlier detection of bugs and reduced project lead times were the top three benefits, while getting DevOps capable members into a team, finding experienced professionals to support DevOps practice and changing deep-seated company culture to support DevOps were the top three challenges. DevOps practices are still emerging. Although 85% of respondents report continuous integration as a frequent practice, only 54% report using continuous deployment frequently. The biggest reported impacts of DevOps on software development culture were in making development team members aware of operational faults, responsible for quality assurance, and responsible for deployments. Realisation of benefits from DevOps depends largely on a culture change. Results are useful for guiding organisations considering DevOps adoption.
