What is DevOps? [2:22]
DevOps is defined as a culture or practice that enhances an organisation's ability to deliver applications more effectively. The primary goal of any organisation is delivery, making it a key factor in DevOps. DevOps involves improving delivery speed, ensuring automation, maintaining quality, implementing monitoring, and ensuring continuous testing. The presenter defines DevOps as a process of improving application delivery by ensuring proper automation, maintained quality, continuous monitoring (or observability), and continuous testing.
Why DevOps? [12:36]
The video explains the evolution of DevOps by contrasting the software development process from 10 years ago with today's practices. Previously, the process involved multiple roles such as system administrators, build and release engineers, and server administrators, leading to slower delivery times. DevOps emerged to streamline this process by automating it and fostering a culture of collaboration within a single team. This approach improves the delivery process by adopting automation, ensuring quality, continuous monitoring, and continuous testing.
