US-based technology firm Spirent Communication has announced the acquisition of cloud and app testing specialist Mu Dynamics in a $40 million deal that further extends its capabilities.

Spirent, which provides test and measurement solutions for development labs, communication networks and IT organisations — including systems for electrical vehicles – will integrate Mu’s service into its platforms, provide a more thorough offering for enterprise and developer customers.

The deal will beef up Spirent’s infrastructure security testing capabilities and see it add Mu’s expertise in measurement and testing cloud-based applications and applications-aware networks.

“Infrastructure security testing is critical to ensuring confidence in the use of globally-deployed networks and applications,” said Bill Burns, CEO of Spirent. “Mu Dynamics brings additional market-leading expertise in cyber security, usability and application emulation to the Spirent solutions portfolio.”

Dave Kresse, CEO of Mu, is confident that the deal will better showcase the company’s solutions and increase its visibility and usage worldwide.”We’re excited that this transaction will accelerate the global deployment of our solutions, and enable their integration into Spirent’s leading performance test solutions,” he said.

The deal sees Spirent pick up recently launched Blitz.io, a cloud-based service from Mu that allows developers to test ‘software as a service’ features for apps and websites more easily.

Blitz.io plays an important part in enabling sites, APIs and apps to be test and tweaked to ensure that they are performing as they need to.

The site tests products with a burst up to 50,000 concurrent worldwide users, helping developers to identify weaknesses, infrastructure issues and bugs; all of which are vitally important for keeping services up and running without glitches.
