The document discusses a study on the energy efficiency of various cloud computing patterns. It implemented patterns like proxy, sharding, and message queues in a movie rental application and measured the average response time and energy consumption using different numbers of clients and connections. The results showed that while cloud patterns can reduce response time, they may increase overall energy usage, and combining patterns further improves performance but at a higher energy cost. The study demonstrated how cloud patterns impact quality of service and energy consumption.

Vu Pham Proxy • Query is passed over the REST call. • Identify if the query is ‘read’ or ‘write’ to hit the corresponding slave. • Response from the slave: HTTP no content, HTTP OK. • logic.ProxyRestCaller; Cloud Patterns Implementations 7 How Green are Cloud Patterns? Rout Method Description NoProxy Direct hit Random Choose randomly an instance Round-Robin Choose the next instance that has not yet been used in “round” Custom Two metrics: ping response time, number of active connections
