In a nutshell, DevOps Engineers are ops-focused engineers who solve development pipeline problems. Site Reliability Engineers are development-focused engineers who solve operational, scale, and reliability problems.
While DevOps aims to handle runtime errors and allow teams to learn from them, SRE enforces error management through Service Level Commitments (SLx) to ensure all failures are handled. SRE also allows for a risk budget that allows teams to test the limits of failure for reevaluation and innovation.
If you're curious, love to learn about new things, and are passionate about designing, building, and running complex systems, then becoming an SRE makes perfect sense. An SRE team enhances the availability, performance, efficiency, monitoring, emergency response, and planning of production services and software.
