Learning Outcomes
DevOps is the cornerstone of modern software development teams, but also the modern way of developing software in enterprise environments. It is an innovative process, which combines the skills of software development teams (developers) and operations (IT operations), with the aim of improving collaboration and productivity, through the automation of infrastructures (infrastructure), workflows (workflows) , and the continuous monitoring of the performance of the application under development. Unlike the monolithic and now obsolete software development model followed earlier, with the introduction of DevOps, software is programmed in small parts, which are integrated, tested, monitored and developed in parallel, saving time and money, but also ensuring their interoperability
Upon successful completion of the course, the student will be able to manage and automate several software installation/configuration processes as well as the preparation of the infrastructure and services that will support modern information systems.
