So who's using platform as a service?
So how many developers working on next generation applications are using Cloud Foundry or other platforms as a service? Sam Ramji said no one knows for sure, but he thinks many enterprises are adopters. "If you have just four developers, a platform is less valuable than at Citigroup, with 40,000," he said. A PaaS adds economies of scale to development projects, keeping large numbers of developers working with the same tools and conventions than they otherwise might use and managing their code more effectively. "Bigger companies can do the math pretty quickly," he said.
