SHARE IBM Corp. is acquiring Turbonomic Inc., a Boston-based company with a platform that helps enterprises reduce cloud expenses and improve their applications’ performance. IBM didn’t disclose the value of the deal, which was announced this morning. But sources told Reuters that the transaction values Turbonomic at between $1.5 billion and $2 billion. That’s a significant premium over the $963 million private valuation that the company is said to have received after its last funding round. Turbonomic offers a so-called application resource management platform that uses artificial intelligence to help enterprises optimize their public cloud environments. The platform focuses on two main use cases. The first is optimizing cloud applications’ performance, while the other is reducing the infrastructure costs they incur.
