For what it's worth, Google has offered this since at least February of 2005. I'm unsure as to why a decade old service was posted.
New version? A reminder they are still making them and improving on it?
We had a couple of these at my old job. Really neat stuff. At least at the time they shipped you new ones when they came out. They also had a 56k modem on them so that they could dial into the serial console to debug them. This is a really neat business model that seemed to work well in that case.
What is the pricing?
IIRC it was $50,000 USD for 2 years per appliance; that might have been per 2 appliances.
Undoubtedly custom per client, they only have 'get in touch' contact as an option
The secret? it's just an elasticsearch instance ;)
