Google Cloud acquires Cornerstone to help customers migrate their mainframes

Google Clouds shopping list shows no signs of abating, with the company announcing the acquisition of Cornerstone Technology, a mainframe specialist.The 30-year-old provider, based in the Netherlands, has an overall remit of ‘helping customers protect and improve their investments in essential legacy enterprise applications’, in Cornerstone’s own words. Cornerstone uses automation to break down programs, turn them into services, and then make them cloud-native.This includes COBOL, which to the potential surprise of many is still used by many enterprises. A recent study from Micro Focus, the language’s arbiter, noted that for more than two thirds of businesses polled, COBOL app modernisation was a preferred strategy to replacement and retirement.As the industry increasingly builds applications as a set of services, many customers want to break their mainframe monolith programs into either Java monoliths or Java microservices, wrote Howard Weale, Google Cloud director of transformation practice in a blog post. “This approach to application modernisation is at the heart of the Cornerstone toolset.Google Cloud made a spree of acquisitions in 2019 under the leadership of CEO Thomas Kurian. The standout deal was for business intelligence platform Looker in June, valued as a $2.6 billion all-cash transaction. Other deals were for data migration service provider Alooma in February, storage firm Elastifile in July, and VMware workload runner CloudSimple in November.
