I blogged about Nirvanix here on Network Computing back in November, and opined that the time to execute with cloud offerings is now. I have been following Nirvanix closely since then, and speaking candidly with its customers. It is clear that the company is executing well, providing substantial value to its existing customers, gaining new customers and fine-tuning offerings in order to take the competition head on. Nirvanix has its sights set on the high end of the competitive spectrum. The company is making gains in market traction and turning prospects away from stalwarts like EMC and IBM.
