VMWare has just released vFabric version 5, promoting various capabilities that would interest developers, architects and projects managers who are worried about getting hosed by a licensing model that punishes sites for temporary successes that trigger the occassional traffic peak. Combining per-VM lisencing and an average-usage licensing model, VMWare is asserting that theirs is the most flexible licensing model in the industry.
Says SpringSource's David McJannet, "The really innovative aspect of vFabric 5 is the fact that while it is licensed on a per VM basis, beyond that, we also believe in licensing on an average usage basis. We think averaging use is more appropriate than requiring a customer to license vFabric based on the high watermark of their application’s needs."
VMWare's Unfair Competitive Advantage
Of course, VMware is also promoting the unfair competitive advantage they have over their competitors that their acquisition of SpringSource has given them. With half of the enterprise applications in production using some Spring project or another, getting clients to move to vSphere and vFabric should be a fairly easy sell, especially if VMWare continues to optimize vFabric for Spring based applications.
"Our approach ensures that the best place to run any of your applications is on vSphere, and secondarily, vSphere is the very best place to run your Spring applications" says McJannet. "Whether it be your monitoring technologies, whether it be your web server, whether it is your in-memory data technologies, really all the components we believe you need to run modern applications on virtual infrastructure are available in vFabric 5."
