I've been pondering whether DevOps engineers really need a deep understanding of business logic. My recent experiences on real-world projects have highlighted that applications often demand insight into business requirements to function optimally. For instance, when setting up CI/CD pipelines, knowing what aspects are crucial for the app (like key workflows or edge cases) can significantly affect decisions. Similarly, when it comes to monitoring, it's challenging to determine alert criteria without grasping what's considered 'business critical.' In terms of scaling, knowing which services impact users or revenue is vital. However, I've come across suggestions that DevOps professionals should maintain a focus primarily on infrastructure rather than diving into application logic. So, what's the consensus? How deep should a DevOps engineer go into understanding business logic—do they need to think like a backend developer or product manager, or is a high-level understanding sufficient?

In general, a high-level understanding seems to work, but as I’ve learned, context is key. Decisions we make in infrastructure and monitoring depend heavily on understanding what’s crucial for the product. Knowing which services affect revenue or customer satisfaction can steer you in the right direction.
You need to get as deep as necessary to make informed decisions. For instance, if you're optimizing backend systems or ensuring security, understanding the business context shapes how you approach your work. It all begins with business needs, but if those are met, then you can focus on the technical side without worrying too much about the deeper logic.
It really depends on the company structure. If you're in a cross-functional team, then knowing business logic is a must. In a larger enterprise supporting many projects, though, it's less critical. You need to gauge how close your work is to the application itself to determine how deep you should go into the business aspects.
Yes, understanding business logic is important, especially if your work involves applications tied to a specific business domain. While it varies depending on your role, knowing the context can enhance your ability to argue against certain proposals and help manage operational risks. Also, it often leads to better decision-making and prioritization of duties.
I get that! In my company, we mostly have SRE and DevOps roles without dedicated platform engineers, and I find that most of our team only knows about 10% of business logic. I’d love to hear how other companies manage this, especially with different role divisions.
I completely agree! Being aware of the 'why' certainly helps in prioritizing tasks better.
How deep? As deep as it allows you to improve your work. The better you understand how the applications work in relation to the business, the more valuable your contributions will be. This includes choosing what to monitor and prioritize in your pipelines, which is often driven by business outcomes.
I think some here might not clearly differentiate between business goals and technical execution. As a DevOps engineer, while you don't need to grasp every nuance, knowing the basics of business logic improves your work significantly.
