Amazon today disclosed that its subsidiary Amazon Web Services (AWS), a cloud infrastructure provider that companies use to run applications, brought in $2.4 billion in revenue for the fourth quarter of 2015. That’s a 69.37 percent year-over-year increase.

That growth rate is lower than it was in the prior quarter, when AWS posted a 78 percent increase in growth, according to today’s earnings statement. And the revenue figure matches the average of estimates from analysts at FactSet, which was $2.4 billion, according to FactSet. The raw AWS revenue figure has never been higher — in the third quarter it was $2.08 billion.

For all of 2015, AWS fetched Amazon a whopping $7.88 billion.

AWS brought in $687 million in operating income for the quarter. That’s up from $240 million one year earlier. The operating expenditures for AWS for the quarter came in at $1.718 billion, up from $1.18 billion a year earlier.

AWS leads the cloud infrastructure market. Competitors include Microsoft Azure, the Google Cloud Platform, and IBM SoftLayer. It’s unclear how far behind these clouds are, as their parent companies don’t disclose financials in the same exact way that Amazon does.
