BigInsights on the cloud is available in both basic and enterprise editions with the options of public, private and hybrid cloud deployments. The basic edition is an entry-level offering available at no-charge that helps organizations learn how to do big data analytics including "what-if" scenarios with its BigSheets component. Clients can move to the enterprise edition when ready and set up Hadoop clusters in under 30 minutes to start analyzing data with low usage rates starting at $0.60 (US) per cluster, per hour. Both versions include a developer sandbox where clients can develop business analytics applications complete with tools and a test and development environment.
