A Closer Look at the Public Cloud Services Market

Public cloud adoption is increasing and private cloud adoption is declining, according to the "2019 State of the Cloud" report from IT asset management provider Flexera. Also, the report revealed that Amazon Web Services (AWS) is the top choice among public cloud services, followed by Microsoft Azure and Google Cloud Platform.

Still, publics are watching closely amid Microsoft's recent victory over AWS for the Pentagon's highly contested JEDI Cloud contract.

Expect the demand for public cloud services to continue to increase in the foreseeable future as well.

Enterprises said they plan to spend 24 percent more on public cloud in 2019 than they did in 2018, the Flexera report indicated. Meanwhile, 8 percent of enterprises noted they spend more than $12 million a year on public cloud, and 50 percent spend more than $1.2 million annually.
