Rightly or wrongly, iCloud is one of Apple’s most regularly criticized products (speaking personally, I’ve never had any major problems with it, but I use Google’s rival service far more.) It seems that Apple is more than aware of the negative feedback, however, because it’s in the process of improving the back-end infrastructure needed to support its cloud-based services.
Firstly, the company bought FoundationDB, a Virginia-based startup, which specializes in handling large chunks of data very quickly. Now a separate report claims that Apple acquired U.K.-based big data analytics firm Acunu sometime in late 2013, with the likely effort of using its database technology for providing analytics related to iCloud services.
