This thesis made the following contributions. As a result, clients will pay exactly for the performance they are actually experiencing; on the other hand, administrators will be able to maximize their total revenue by utilizing application performance models and SLAs.
Abstract Resource allocation strategies in virtualized data centers have received considerable attention recently as they can have substantial impact on the energy efficiency of a data center.
Finally, we proposed a revenue-driven resource allocation algorithm which maximizes the SLA-generated revenue for a data center. Cloud users can size their VMs appropriately and pay only for the resources that they need; service providers can also offer a new charging model based on the VMs performance instead of their configured sizes.
First, we precisely estimated capacity requirements of client virtual machines VMs while renting server space in cloud environment.
Server management now involves dealing with multiple dissimilar applications with varying Service-Level-Agreements SLAs and multiple resource dimensions.
We focus on dynamic environments where virtual machines need to be allocated and deallocated to servers over time. First, we identified resource control parameters crucial for distributing physical resources and characterizing contention for virtualized applications in a shared hosting environment.
However, these placement heuristics can lead to suboptimal server utilization, because they cannot consider virtual machines, which arrive in the future. We specifically addressed two crucial data center operations. Previous article in issue. Second, we explored several modeling techniques and confirmed the suitability of two machine learning tools, Artificial Neural Network and Support Vector Machine, to accurately model the performance of virtualized applications.
Second, we proposed a systematic process to efficiently allocate physical resources to hosted VMs in a data center. The benefits of accurate application performance modeling are multifold. We found that combinations of placement controllers and periodic reallocations achieve the highest energy efficiency subject to predefined service levels.
Third, we presented an approach to optimal VM sizing by employing the performance models we created. We compare VM allocation strategies for cloud environments experimentally.
This led to new decision and control strategies with significant managerial impact for IT service providers. We ran extensive lab experiments and simulations with different controllers and different workloads to understand which control strategies achieve high levels of energy efficiency in different workload environments.
This thesis aimed to develop a framework and techniques that would help substantially reduce data center management complexity. Moreover, we suggested and evaluated modeling optimizations necessary to improve prediction accuracy when using these modeling tools.
To realize these dual objectives, accurately capturing the effects of resource allocations on application performance is vital. The multiplicity and diversity of resources and applications are rendering administrative tasks more complex and challenging. While the type of placement heuristic had little impact on the average server demand, the type of virtual machine resource demand estimator used for the placement decisions had a significant impact on the overall energy efficiency.By overbooking cluster resources in a controlled fashion, our platform can provide performance guarantees to applications even when overbooked, and combine these techniques with commonly used QoS resource allocation mechanisms to provide application isolation and performance guarantees at run-time.
