SUMMARY:

Cloud computing provides a centralized, service-oriented infrastructure for users around the world. A cloud environment allows running critical applications sensitive to user interaction (such as an online web search), and is also used to run best-effort oriented batch applications (such as audio/video compression, indexing of web pages). Data centers are designed on a large scale to support the various cloud services, distributed across hundreds of thousands of servers, with significant operational and capital expenditures. Thus, optimizing the use of server resources results in significant savings on these systems. As a research opportunity, there is the possibility of exploring idle moments of servers that run critical services, especially during periods of low demand. This research aims to co-locate different types of cloud application tasks (latency-sensitive and best-effort) on the same server in order to increase its utilization, thus improving its efficiency. The work demonstrates that performing co-allocation of latency-sensitive and best-effort tasks provides greater efficiency for cloud servers, as long as the performance of critical application tasks is guaranteed. The work explored the use of specific schedulers for each type of task, latency-sensitive tasks were scheduled and parameterized via real-time scheduling, and batch application tasks used fair best-effort scheduling. The gains in relation to the standard scheduler of the system reached up to 150% when compared to the one proposed in this work, here called EDFCoaloc.
