CoT: Decentralized Elastic Caches for Cloud Environments

Understand

Distributed caches are widely deployed to serve social networks and web applications at billion-user scales.

• This paper presents Cache-on-Track (CoT), a decentralized, elastic, and predictive caching framework for cloud environments.
• CoT proposes a new cache replacement policy specifically tailored for small front-end caches that serve skewed workloads.
• Front-end servers use a heavy hitter tracking algorithm to continuously track the top-k hot keys.
