I find it really annoying that these tech news sites (read TechCrunch) never link to the company. Always to crunchbase or in this case some silly twitter search about Cloudkick.
Anyway, they do seem to have pretty good coverage for the major providers (https://www.cloudkick.com/providers/) Anyone used their service in production?
Lots of YC funded startups use them. Everyone seems happy with the service.
On top of the monitoring and metrics they're providing, imagine if they could provide application deployment and ensuring server state across multiple clouds. They could leverage Puppet and perhaps other tools like Capistrano to roll out new applications across the clouds, with all information centrally available. It would further reduce a company's need to have their own DevOps guy(s). Tie it in with RCS like git / SVN, even. Partner with Splunk for syslog analysis. The possibilities are endless, and the power for startup companies seems incredible.
This is the first time I've seen Cloudkick, and it looks amazing. I love watching companies that enable other companies to focus on their end product instead of all of the technical operations surrounding their end product. Congrats on your recent round, and it will be fun watching your feature set grow.
