By Jason Brazile, Remi Locherer, Ronnie Brunner, Netcetera, Switzerland http://guide.jazoon.com/#/submissions/145 As Infrastructure as a Service (IaaS) offerings in the cloud become more compelling, new collaboration possibilities emerge. A large European agency wished to offer vast satellite imagery free of charge to users who develop good applications for it. Instead of sending data to developers, why not offer a dev environment in the cloud? This talk describes an automated trusted remote Java development sandbox hosted in the Amazon cloud that uses strong encryption for system authentication and file system services, Security-conscious users can trust that their application intellectual property won't be leaked while trusting neither the cloud provider nor the operators who deploy and maintain the cloud-based sandbox service running on top of it.
