DevOps is a method that integrates IT operations and software development. It allows companies to release new software and make changes to users as fast as possible using automation. Due to the quick adoption of DevOps practices, DevOps tools have been in high demand for the last few years.
Many statistics strongly support and prove this result. The IT and Telecom sector in the USA retained almost 30% of the market share in 2019. And this was because of the growing use of DevOps tools for adding to the NFV (Network Function Virtualization) technologies and dealing with their container-based networks.
Moreover, the global profit of the DevOps software tools market was $8.5 billion in total by the end of 2019. Also, in the present decline due to the pandemic, IDC discovered that the market of the DevOps software tools has grown a lot in 2020 and 2021.
