## about this category
Infrastructure and DevOps covers everything that runs beneath the code: cloud computing (AWS, Google Cloud, Azure), containers and CI/CD pipelines, relational and NoSQL databases, networking, and the hardware and operating-system layer that decides real performance. The guides translate that foundation into practical decisions about architecture, cost and reliability.
