Apple reportedly acquired U.K.-based big data analytics firm Acunu back in 2013, with the company's tools said to bolster back-end data infrastructure for services such as iCloud.
News of Acunu's acquisition comes on the heels of yesterday's announcement that Apple acquired database software company FoundationDB, a move aimed at improving server-side technologies for Apple's digital content distribution services such as the App Store and iTunes.
Acunu's database technology was likely retooled to provide analytics for services such as iCloud, with Bloomberg stating:
Acunu produced technology to provide analytics on databases. Its technology can work with and improve other tools, like the free Cassandra database, which Apple runs on several thousand computers.
With an iTunes Radio revamp planned for later this year along with the launch of a new 25-channel TV streaming service, it is no wonder that Apple is focusing on improving the back-end architecture for its cloud-based services.
