CompTIA IT Pro: How did the practice of DevSecOps begin
Let’s start with a trip in the 'Wayback Machine' to look at a more traditional way of how IT teams work within companies: Developers code and IT pros manage infrastructure or operations. Traditionally, they are isolated from each other because they have different interests and priorities.
Here’s how this works in practice: A developer will develop code on a test server. Once the development cycle is finished, the developer drops it onto an infrastructure server, and everyone expects it to work. But then testing doesn’t go well because the environment has changed during the development phase, so the developer has to reassess and make adjustments.
DevOps is when you put these two functions together. Instead of developing in isolation, developers and infrastructure pros test code at various interface points along the way, so they don’t have to completely start from scratch.
Management, developers and operations are all looking at the same scoreboard, all progressing toward the same goal, and everyone is on the same page. They’re also moving from waterfall-style project management to agile, kanban or scrum project management. Everyone sees what is being done, participates in active sessions where they exchange ideas, and if they see something that doesn’t make sense, they align to it or raise the red flag.
