Elastic Provisioning of Cloud Caches: a Cost-aware TTL Approach
We consider elastic resource provisioning in the cloud, focusing on in-memory key-value stores used as caches. Our goal is to dynamically scale resources to the traffic pattern minimizing the overall cost, which includes not only the storage cost, but also the cost due to misses. In fact, a small variation on the cache miss ratio may have a significant impact on user perceived performance in mo...
متن کاملKingfisher: A System for Elastic Cost-aware Provisioning in the Cloud
Cloud computing platforms allow application providers to rent server capacity to run hosted applications and to dynamically vary the rented capacity to match demand. Today’s cloud platforms offer a plethora of different server configurations for rent and price them differently on a cost-per-core basis. Furthermore, cloud platforms support different replication and migration mechanisms to suppor...
متن کاملModeling TTL-based Internet Caches
This paper presents a way of modeling the hit rates of caches that use a time-to-live (TTL)-based consistency policy. TTL-based consistency, as exemplified by DNS and Web caches, is a policy in which a data item, once retrieved, remains valid for a period known as the “time-to-live”. Cache systems using large TTL periods are known to have high hit rates and scale well, but the effects of using ...

متن کاملPolicy-Aware Provisioning of Cloud Applications
The automated provisioning of complex composite Cloud applications is a major issue and of vital importance in Cloud computing. It is key to enable Cloud properties such as pay-as-you-go pricing, on-demand self-service, and elasticity. The functional aspects of provisioning such as instantiating virtual machines or installing software components are covered by several technologies on different ...
