If you’re at all familiar with cloud computing, you know Amazon Web Services is a giant – but just how big is AWS? There are a number of measures of the size of a cloud business like Amazon’s –– here are answers to just a few of those questions.

How big is AWS’s staff?

While numbers for employees of Amazon as a whole are reported in the company’s quarterly earnings reports (630,600 as of Q1 2019), the number of those under AWS is less clear.

AWS has just over 40,000 employees listed on LinkedIn, but of course, that’s not the most accurate measure. By eyeballing the operating expenses reported for the AWS segment compared to Amazon’s business as a whole, you could estimate up to 62,000, but it’s likely lower than that. As of this writing, AWS has 12,280 full-time job openings listed on their website, while Amazon as a whole has 32,454 openings.

How big is AWS’s infrastructure?

AWS has 66 availability zones within 21 geographic regions around the world. Each availability zone consists of one to dozens of individual data centers. To visualize these data centers, check out AWS’s exploration of them here.

How big is AWS’s list of products?

When we last counted in April, there were 170 unique services listed on AWS’s offerings page, and there could certainly be more by now. These range from core compute products like EC2 to newer releases like AWS Deepracer for machine learning. Look for a spike in this count after AWS re:Invent in early December, as the cloud provider tends to save up announcements for its yearly user conference.

Speaking of…

How big is AWS re:Invent?

In 2018, AWS re:Invent pulled 52,000 attendees, and AWS estimates a crowd of 62,000 for 2019, each year taking up a large portion of the Las Vegas Strip.

In comparison, Microsoft Ignite expects 25,000 attendees this year, Google Cloud Next estimated 30,000 attendees, and VMworld estimates 21,000 attendees. Then again, Salesforce’s Dreamforce 2018 drew 170,000 attendees, and Consumer Electronics Show (CES) reports 175,212 attendees for 2019. So while AWS re:Invent may be large for a cloud-specific conference, it’s not quite a giant as far as tech shows go.
