DevOps is a culture, movement or practice that emphasises the collaboration and communication of both software developers and other IT professionals, while automating the process of software delivery and infrastructure changes. It aims to establish a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably.
Implementing the culture and practices of DevOps can be easier in small, lean organisations where engineers, developers, and IT operations all operate from the same office.
However, it is likely to be a more difficult and complicated transition in large, established organisations with complex legacy systems. Here, organisations can be plagued by siloed business functions, with little or no communication across different silos.
If an organisation wants to change critical IT infrastructure, achieving compliance and ‘buy-in’ from all departments can prove challenging.
With DevOps it can be different – when development and operations collaborate and work together towards the same goal, the results can be extraordinary. Organisations regularly report increased deployment speed and frequency, higher quality product output and lower failure rates.
