At LinkedIn, we are using this curriculum for onboarding our entry-level talents into the SRE role.
Site Reliability Engineers (SREs) sits at the intersection of software engineering and systems engineering. While there are potentially infinite permutations and combinations of how infrastructure and software components can be put together to achieve an objective, focusing on foundational skills allows SREs to work with complex systems and software, regardless of whether these systems are proprietary, 3rd party, open systems, run on cloud/on-prem infrastructure, etc. Particularly important is to gain a deep understanding of how these areas of systems and infrastructure relate to each other and interact with each other. The combination of software and systems engineering skills is rare and is generally built over time with exposure to a wide variety of infrastructure, systems, and software.
