A compelling product. The dashboard looks great. They even replaced the confusing term "user data" with "launch script", but they fall back into it later. SSH in-browser is great too and can be bookmarked/opened in a fullscreen tab. Uploading (instead of pasting) your SSH pubkey is a bit annoying. The docs appear to say you can add these to a VPC but I don't see how to do it. They don't say the SSD storage is local,…
The terrible IOPS performance on AWS is the biggest downside for me. All competitors seem to outstrip AWS on this. Do they have some legacy infrastructure that is just too big too upgrade to something more modern, or is this "on purpose"?
Many competitors just use local storage, which comes with its own serious downsides for the company and customer. DigitalOcean just recently launched its Volumes service, but it's very limited compared to EBS, and not nearly as fast as its local SSDs.
EBS is generally fine but I would really enjoy the option to have ~40GB local SSDs for caching (but I suppose you can always grab an r3/r4 and cache in memory if that's your bag).
The best cloud I/O perf I've seen, bar none, comes from Joyent's Triton containers. Beats even DO by 3-4x. Beyond that you need to go bare-metal.
