云计算是一种范式，它允许以“付款方式”的基础使用外包基础架构，这要归功于可以根据需要构建可扩展和可自定义的基础架构。所需的虚拟机（VM）的数量和类型的能力决定了最终预算，因此它代表了有效管理云基础架构的关键。为了开发针对与云计算有关的不同主题的新建议（例如，数据中心管理或资源提供），需要大量工作和金钱来设置适当尺寸的测试台，包括来自不同组织和公众的不同数据中心云提供商。因此，将模拟用作研究复杂场景的工具更容易。考虑到这一点，本文介绍了Icancloud，这是一个具有显着特征的云基础架构的新型模拟器，例如可用性，灵活性，性能和可扩展性。该工具专门旨在模拟亚马逊提供的实例类型，因此这些工具的模型包含在模拟框架中。还介绍了通过比较使用ICancloud获得的结果和在给定应用程序上下文中进行验证的数学模型进行的准确性实验。这些说明了Icancloud在重现Amazon实例类型的行为方面的效率。
Cloud computing is a paradigm which allows the use of outsourced infrastructures in a "pay-as-you-go" basis, thanks to which scalable and customizable infrastructures can be built on demand. The ability to infer the number and type of the Virtual Machines (VM) needed determines the final budget, thus it represents a key in order to efficiently manage a cloud infrastructure. In order to develop new proposals aimed at different topics related to cloud computing (for example, datacenter management, or provision of resources), a lot of work and money is required to set up an adequately sized testbed including different datacenters from different organizations and public cloud providers. Therefore, it is easier to use simulation as a tool for studying complex scenarios. With this in mind, this paper introduces iCanCloud, a novel simulator of cloud infrastructures with remarkable features such as usability, flexibility, performance and scalability. This tool is specially aimed at simulating instance types provided by Amazon, so models of these are included in the simulation framework. Accuracy experiments conducted by means of comparing results obtained using iCanCloud and a validated mathematical model of Amazon in the context of a given application are also presented. These illustrate the efficiency of iCanCloud at reproducing the behavior of Amazon instance types.
