Combining Redis and CDN
Learn how to architect systems that leverage both Redis for application-level caching and CDNs for static asset delivery.
Intro to Hybrid Caching
Welcome! In this lesson, we'll learn how to combine two powerful caching tools: Redis and Content Delivery Networks (CDNs). This approach is called hybrid caching.
By combining them, we leverage their unique strengths to create a highly performant and scalable system. It's like having specialized tools for different jobs!
Redis: Dynamic Data Powerhouse
Redis is an in-memory data store, perfect for caching dynamic, frequently changing data that your application generates or retrieves from a database.
- User Sessions: Storing login tokens.
- Personalized Feeds: Caching a user's unique content.
- Database Query Results: Storing results of expensive queries.
It sits close to your application, providing lightning-fast access to this data.
