Cloud computing services have taken off in recent years. They give businesses flexible access to computing hardware and resources without all the burden of having to manage infrastructure themselves. But there are times when some customers might benefit a great deal from managing the underlying infrastructure.
In a presentation this week at Usenix Annual Technical Conference '10 in Boston, Vytautas Valancius, a computer science researcher at Georgia Institute of Technology, described a system that would let cloud users customize the path their data takes as it travels through cloud computing platforms. Such a path could span multiple Internet service providers and networks.
Different types of cloud applications have different needs, Valancius explained. For example, a highly interactive application such as a voice chat program probably needs a high-quality connection. In contrast, a file-backup service that transfers data in bulk might benefit from the least expensive transit between machines.
