#tools for devops

DevOps is a set of practices which combines software development and IT operations with the aim to shorten the system development life cycle. It is an organization approach which enables faster development of applications and easier maintenance of existing deployments. The approach promotes shorter, more controllable iterations, automations and new tools. 

DevOps is not just a technology, it covers everything from organization culture, processes and tools. It is a cultural change that allows the organization to break down the barrier between the development team and operations teams. DevOps includes continuous integration and continuous delivery (CI/CD), real-time monitoring, incident response systems and collaboration platforms. 

DevOps is the catalyst to start this cultural shift and bring the whole IT team together in the agile mindset to improve the deployment frequency, allowing a faster time to market, a lower failure rate of new releases, shortened lead team and faster mean time recovery. 

Despite DevOps being a cultural shift for an organization, the approach requires teams to adopt and use certain tools which would help the team to automate and enhance their processes.
