According to the CAP Theorem, a distributed system can only provide two of these three guarantees simultaneously. Scalable systems often favor Availability and Partition Tolerance (AP) over strict consistency. 2. Microservices Architecture
These chapters provide a substantial introduction, covering the core concepts of scalability, replication, state management, and load balancing. The free PDF version of these chapters is distributed by O'Reilly and has been promoted by partners like Cockroach Labs and covered in tech publications like DBTA. foundations of scalable systems pdf github free

Scaling systems is hard, but the pathway to mastery can be free. By combining the official free chapters from Cockroach Labs with the community-driven resources on GitHub, you can start building the knowledge you need to design architectures that grow with your users.
To build systems that scale, engineers must move beyond basic coding and master architectural trade-offs. Scaling generally falls into two categories, supported by key structural pillars. Horizontal vs. Vertical Scaling
Adding more machines to the infrastructure pool. This approach offers theoretically infinite scale and high availability but introduces complex network coordination and data synchronization challenges. Core Metrics: Throughput, Latency, and Response Time
