Skynet is a decentralized file storage and CDN platform launched last week as the storage foundation for decentralized applications - https://blog.sia.tech/skynet-bdf0209d6d34
Skynet stands out in terms of performance and speed. A typical time-to-first-byte when downloading a skyfile is between 300ms and 500ms. And a typical throughput for larger downloads is around 1 gigabit per second. The current implementation allows for app devs to access Skynet storage for free via Skynet webportals similar to this one - siasky (dot) net. The list of all webportals is also provided on this website.
Instead of using a centralized cloud service, build your dapps using Skynet to make them truly decentralized.
