CloudFront Distributions
A CloudFront distribution is a set of rules that decide, at an edge location, whether to answer from cache or ask your origin. This lesson covers cache behaviors and their matching order, the cache key, the TTL rules that override your Cache-Control headers, invalidation, HTTPS with custom domains, and locking the origin down with OAC.
Advanced 32 minutes 7 Learning Objectives
- Describe the path a request takes through an edge location, a regional edge cache, and the origin, and name the requests that skip the regional edge cache
- Order cache behaviors correctly and predict which one applies to a given request path
- Explain what the cache key is and identify the settings that lower a cache hit ratio
- Predict the cached duration of an object from the Minimum, Maximum, and Default TTL values and the origin's Cache-Control header
- Choose between invalidation and versioned file names for a content update
- Configure an alternate domain name with HTTPS, including the Region an ACM certificate must live in
- Lock an S3 origin to a distribution with origin access control and explain why OAC replaced OAI
