Dive Brief:

• According to a report from Bitglass, Microsoft is now the leader in cloud productivity apps in the enterprise.

• Microsoft Office 365 adoption grew from 7.7% of surveyed companies last year to 25.2% this year.

• Google grew at a slower pace, moving up to 22.8% from 16.3% 

Dive Insight:

28% of surveyed businesses used a cloud-based productivity and email suite in 2014, compared to the 48% who employed one this year, Bitglass found.

But experts say the usage rates might reflect an increase in cloud adoption among established businesses that Microsoft has long-term relationships with. Google's former lead might be due to early adopters jumping in the space ahead of slower-moving, large companies.

Experts say small- to mid-sized businesses make the shift to the cloud easily since they don't have legacy investments to protect.
