	abstract={The cloud paradigm emerged as an alternative to offer computational resources for users link different technologies released in the last decades (virtualization, grid computing, cluster and parallel processing). Furthermore, the public cloud providers started to offer services and computational resources over the Internet. Meanwhile, the private cloud concept arose being deployed inside the corporations domain. The private cloud becomes suitable because it increases the security and flexibility, and it avoids a third party dependency. Currently, there are several IaaS open source cloud solutions available to build a public or private cloud. In this paper, the open source solutions for IaaS were evaluated in a methodology concerning the features and support for robustness (flexibility and resilience). In addition to that, a survey state of the art for performance on a cloud was conducted to highlight the challenges on the cloud and also, the potential solutions for reducing the cloud performance overhead. The results demonstrated that the open source cloud IaaS solutions may enable high robustness levels and are suitable for enterprise applications. In this approach, the most flexible IaaS tool is CloudStack as well as OpenStack is the most resilient. In addition, an equation for find the reliability rates of experiments on the cloud is presented. Finally, several aspects need to be studied in the future.},
