DevOps is a methodology which brings together the development (Dev) and operations (Ops) of software. Instead of developers and system administrators working in separate teams, they are combined into one team and share responsibility for building, testing, releasing and managing one or more applications. Through this collaboration, DevOps teams are able to develop and deploy software updates faster, more frequently and more reliably.
Although DevOps has become a popular term, there is no standard definition of DevOps. Many organizations have their own interpretation of the methodology. However, there are a number of principles that are often found in DevOps practices, such as:
- Shared ownership: Bringing developers and system administrators together in one team, so they are jointly responsible for building, testing, releasing and managing software.
- Automation: Automating processes such as building, testing and deploying software, so that this can be done faster and with fewer errors.
- Fast feedback: Continuously monitoring software and infrastructure, so that problems are quickly detected and resolved.
