Achieving high availability requires eliminating single points of failure and ensuring that system components can gracefully degrade or failover when disruptions occur.
Scalable systems are designed to handle increased load and usage without sacrificing performance. The foundations of scalable systems involve a combination of architectural patterns, design principles, and technologies that enable systems to scale horizontally and vertically. foundations of scalable systems pdf github free
Synchronous HTTP requests bind system components tightly together. If one downstream service slows down, the entire request chain backs up. Scalable systems decouple these dependencies using asynchronous message queues. Message Queues and Event Brokers Message Queues and Event Brokers For implementation, design

Architectural Foundations of Scalable Systems Designing software systems to handle massive growth requires moving away from ad-hoc engineering toward predictable, proven architectural patterns. Scaling is not just about adding more servers; it involves managing data consistency, mitigating network latency, and isolating failures.
Using tools like Redis or Memcached to store session data, database query results, or complex API responses.
