Scalability for Dummies - Part 3: Cache

In Scalability for Dummies - Part 2: Database , we optimized the database using indexes, connection pools, replicas, and other techniques. But even a healthy database can become overloaded when users repeatedly request the same products, articles, profiles, and configuration data. This is where cach
