Too Long; Didn't Read
Tiered Locality is a feature led by my colleague Andrew Audibert at Alluxio. Tiered locality uses awareness of network topology and configurable policies to manage data placement for performance and cost optimization. This article dives into the details of how tiered locality helps provide optimized performance and lower costs. It can also be useful for cost savings in environments where cross-zone or cross-location traffic is more expensive than intra-zone data traffic. The closer or more localized the data is, the faster the application can retrieve it.
