Amazon has posted its financial reports for the second fiscal quarter of 2016, and its Amazon Web Services (AWS) cloud computing unit posted record-breaking revenues of $2.9 billion. That compares to sales of $2.5 billion in the first quarter and $1.8 billion a year ago.
AWS's operating income was $718 million, which was more than half of Amazon's total income. The cloud computing service had margins of 29.9 percent, an increase from 27.9 percent in the first quarter.
Amazon's chief cloud competitors, Microsoft and Google, do not break out exact numbers for their cloud computing divisions.
