As the use of cloud computing resources grows in academic research and industry, so does the likelihood of failures that catastrophically affect the applications being run on the cloud. For that reason, cloud service providers as well as cloud applications need to expect failures and shield their services accordingly. We propose a new model called Failure Scenario as a Service (FSaaS). FSaaS will be utilized across the cloud for testing the resilience of cloud applications. In an effort to provide both Hadoop service and application vendors with the means to test their applications against the risk of massive failure, we focus our efforts on the Hadoop platform. We have generated a series of failure scenarios for certain types of jobs. Customers will be able to choose specific scenarios based on their jobs to evaluate their systems.
