DevOps is a combination of tools and practices designed to increase an organization’s ability to deliver applications and services faster than traditional software development processes. The goal of DevOps is to streamline and automate the application lifecycle to accelerate the delivery of high-quality products. In this DevOps course we provide an in-depth overview of the DevOps referring to such key practices as continuous integration (CI), continuous delivery (CD), automation with Ansible, monitoring with such popular and in-demand tools as Grafana, and how Jenkins brings in collaboration between development and operations teams. The course includes hands-on experience with popular DevOps tools like Git, Docker, Ansible and Grafana with an additional note on Prometheus. We provide DevOps as an instructor-led training.
