Amazon Web Services is crushing the competition in the cloud computing business. With massive data centers all over the world and top companies on the client list, AWS seems light-years ahead of anyone else.

Its revenue last year was $17 billion. It’s ridiculous to even consider how huge that is. To put things in some sort of perspective, the Hosting Tribunal created a list of its top clients for us. Considering the names here can help you visualize the size of AWS.

AWS took on Dropbox in 2007. Admittedly, Dropbox have since invested into servers of their own. However, their partnership with AWS shows the scale of AWS’s operation.

Namely, Dropbox had 500 petabytes of data on Amazon’s servers. That’s 500,000,000 GB. Now, most AWS’s clients don’t use this much space. Still, consider that AWS has over a million active customers and you’ll realize how vast those server farms must be.

Possibly the most famous partner is Netflix. Though they are the top internet entertainment company, Netflix have decided migrating to AWS would be the cheapest and most secure option. Building a new infrastructure that works well with cloud computing allowed them to spread their service literally worldwide. The flexibility of resources still lets them conveniently experiment with new technologies to include in their services.

Finally, the contract that shows the actual security of AWS is the one with CIA. In 2013, CIA picked AWS to build their private cloud. CIA’s chief information officer already stated this was the best decision they had ever made. CIA reportedly achieved incredible results with the private cloud and the CIO dubbed it “probably the most secure thing out there.”

So you can see AWS offers nearly unlimited possibilities to its clients. Add flexibility, security, and a variety of services and AWS is the perfect solution for any medium or large enterprise. To see which of Amazon’s services might suit you, check out the infographic below.
