Telegram doesn't rely on Amazon or any other third-party cloud service. We have built our own secure cloud infrastructure, distributed across the globe. It took us a few years to create the technology to instantly sync encrypted data between our datacenters and to encrypt local storage in each of them in a way that would make breaking into any data-center and seizing servers useless. The encryption keys used to secure the Telegram Cloud are split in pieces and never stored in the same place as the information they protect.

As a result, our approach is  more advanced and secure than what Amazon or any of these general purpose cloud services can offer. And since we run our own infrastructure, providers like Amazon can not block us.
