Alibaba’s strength is in e-commerce but it signaled a move into infrastructure tech when it acquired Data Artisans, a German big data startup that specializes in distributed systems and large-scale data streaming services.

Jon Russel reported on Alibaba’s latest acquisition for TechCrunch:

Data Artisans was founded in 2014 by the team leading the development of Apache Flink, an open source large-scale data processing technology. The startup offers its own dA Platform, with open source Apache Flink and Application Manager, to enterprise customers that include Netflix, ING, Uber and Alibaba itself.

The Chinese e-commerce giant has been working with Data Artisans since 2016, through support and open source work to help the architecture and performance of the software, both companies said in statements. Data Artisans is on record as raising $6.5 million over two rounds, most recently a Series A in 2016 led by Intel Capital, but there was a seemingly unannounced Series B which closed last year and it looks like Alibaba was involved, according to a blog post from Data Artisans co-founders Kostas Tzoumas and Stephan Ewen.

Now Alibaba’s ownership — and you’d also presume, resources — can help the business reach “new horizons” with its open source technology, including moves to “expand to new areas that we have not explored in the past and make sure that Flink becomes a more valuable data processing framework for the modern data-driven, real-time enterprise,” the duo wrote.
