In the above NY Times article of April 23, 2015 (yesterday), it is clear to see from the Synergy Research Group pie chart that:
(1) Amazon enjoys an approximate 28% of Cloud Services marketshare, with Microsoft at 10%.
(2) Most, if not all of the 43% "other" category, along with IBM at 7% and Rackspace at 3% - totaling approximately 53% is Free/Open Source Software (FOSS) "OpenStack" based Cloud technologies, including AT&T, Cisco, EMC, Juniper, Intel and especially Microsoft's most loyal dupes - Dell and HP.
See full list of Openstack users and member companies here:
That means Amazon AWS plus OpenStack based Cloud services represent about 81% marketshare (about 75% at minimum) versus 10% for Microsoft Azure Cloud services.
It thus becomes obvious that a lot of the tech punditry today is from technology non-expert shills pushing their beloved tech company's products and services, as has been proven unequivocally on several occasions in the case for Microsoft.
Crass partisanship and hero worship of specific technologies or companies based solely on ideology and technological ignorance is stupid and a waste of space in technology journalism.
