FederatedCloudSim

2014

Recent developments show that the standardization of cloud service descriptions and exchange leads the way for the rise of cloud federations. In these federations CSPs (cloud service providers) can use resources of other CSPs in the case of a lack of local resources or they can add remote services to their catalogue. Cloud federations again demand for cloud brokers which offer the resources and services of different CSPs transparently to the users. Research of cloud federations in the real world is very complex and expensive as distributed hard- and software scenarios are needed. Therefore we present FederatedCloudSim, a very flexible cloud simulation framework that can be used to simulate …

Financial Evaluation of SLA-based VM Scheduling Strategies for Cloud Federations

2017

In recent years, cloud federations have gained popularity. Small as well as big cloud service providers (CSPs) join federations to reduce their costs, and also cloud management software like OpenStack offers support for federations. In a federation, individual CSPs cooperate such that they can move load to partner clouds at high peaks and possibly offer a wider range of services to their customers. Research in this area addresses the organization of such federations and strategies that CSPs can apply to increase their profit.In this paper we present the latest extensions to the FederatedCloudSim framework that considerably improve the simulation and evaluation of cloud federations. These si…

Evaluation of SLA-based decision strategies for VM scheduling in cloud data centers

2016

Service level agreements (SLAs) gain more and more importance in the area of cloud computing. An SLA is a contract between a customer and a cloud service provider (CSP) in which the CSP guarantees functional and non-functional quality of service parameters for cloud services. Since CSPs have to pay for the hardware used as well as penalties for violating SLAs, they are eager to fulfill these agreements while at the same time optimizing the utilization of their resources.In this paper we examine SLA-aware VM scheduling strategies for cloud data centers. The service level objectives considered are resource usage and availability. The sample resources are CPU and RAM. They can be overprovision…
