You cannot scale servers without distributing the incoming traffic via a load balancer. You also cannot scale a database without placing a caching layer in front of it (e.g., Redis or Memcached).
Building scalable systems requires a deep understanding of the foundations of scalable systems, including modularity, distributed architectures, load balancing, caching, and database design. The PDF resources available on GitHub provide valuable insights into building scalable systems, and can serve as a starting point for architects and engineers looking to design and build large-scale systems.

This article curates the best free PDFs and GitHub repositories that teach you how to build systems that scale from zero to billions of users.
To give you a taste of the value in the free PDF, here is a breakdown of the key concepts covered in the official O'Reilly sample chapters:
Splitting a relational database across multiple machines based on a key (e.g., User ID), combined with read-replicas to offload read traffic. You cannot scale servers without distributing the incoming
While not typically free, the principles discussed in this book are foundational. Many developers create summaries or GitHub repos dedicated to DDIA notes. Core Topics to Study

Before designing a scalable system, you must understand how to scale. Scalability is a system's ability to handle increased load by adding resources. The PDF resources available on GitHub provide valuable
