Google stands third in cloud computing, a popular mean for enterprises to conduct their IT operations. Global cloud computing business accounts for $20 billion a year and has been forecast to grow 35% over the next year, reports Bloomberg citing data procured from Gartner Inc. as the source. However, Synergy Research represents Google as the fourth dominant player in cloud infrastructure services.

The Alphabet Inc. subsidiary intends to massively expand its network of data centers in order to climb the ranking. Its cloud computing business has generated $500 million in revenue during last year according to data furnished by analysts at Goldman Sachs.

The revenue may be compared with $74.5 billion overall for its parent company. However, cloud business has already established itself as one of its fastest growing business areas.

Google has apparently started finding ground in cloud computing business. Apple, a long recognized client of Amazon's AWS and Microsoft's Arzu has initiated using Google's cloud for its iCloud. The service enables Apple customers storing music, photos and documents, narrates an industry executive. Spotify, a music service and high profile customer of AWS has announced last month utilizing Google's cloud for some computing infrastructure.

Google has been extending data centers across the world with developing two new regional centers in Japan and Oregon to reach the number of regions it serves to five. The Silicon Valley tech giant has kicked off its cloud conference in San Francisco Wednesday with a keynote speech by Greene. Ms. Greene is expected to outline her cloud strategy during her first major public appearance since joining the company.
