Valkey: Latency in Cloud Environments
summary
Valkey (an open-source Redis fork) is examined in cloud deployments where adding a caching layer can actually increase latency because of network hops between the application and Valkey. The talk analyzes how horizontal scaling and distributed host selection can worsen latency and discusses implications for choosing hosts and architecture when using Valkey in cloud environments.
