I have been working for many months on a browser-based Amazon Redshift management console.
I have a live system of the first version running, pointed at a Redshift cluster I have which contains an artificial, generated database.
If it's of interest, you can have a look and poke around and see what you find.
To prevent bots going crazy all over the site, here's the obfuscated URL, it's an IP number of an EC2 instance in us-east-1;
https://
fifty-four.
one-hundred-and-sixty-two.
fifty-eight.
one-hundred-and-twenty-seven
Note the AMI is intended to be run locally, fully firewalled (for PII), and so the SSL cert has to be self-signed - there is no domain name - so you'll need to click past the warnings the browser will give you.
