Cloud pricing calculator, Cloudability has secured $8.7 million in Series A funding, a nod by investors that tracking the cost of cloud services is going to become more important over time. Cloudability provides its users with daily spend updates, predictive alerts and a history of their cloud spending. It’s especially helpful given how easy it is for developers to swipe a credit card and begin using Amazon Web Services almost instantly. Pretty quickly companies discover machines are not being turned off and unexpected spikes and overages are costing them dearly, undermining a key reason for moving to the cloud in the first place. Tools like Cloudability, Newvem, Cloudyn and UpTimeCloud help keep cloud spending under control and are a sign of the gradual maturing of the cloud infrastructure market.
