Jan: Would also like an EBS based EC2 AMI available but time constraints as well.... my main issue in that I have not configured an BaseX server as stand alone (wrapped in applications). What do I need on the server (besides the core linux). JRE, Tomcat(?), which baseX jar? Could use elasticserver.com to generate the AMI (so could be used for other virtualization platforms as well). thanks *P

I agree. For better performance, I would recommend EBS based instance as it has better disk performance, not the traditional instance store based on S3. I had in past some issues with performance of PostgreSQL, which was relatively poor.
But I can confirm, that BaseX works on AWS EC2 instance with @root-device="instance-store" @type="m1.small" virtualization="paravirtual". I hope to find time to turn it to EBS based instance store some time.

I think it would be pretty trivial to setup an Amazon EC2 instance running a BaseX server. Probably just need a Linux core with Java installed. This could be shared as a public AMI. best *P On 12/8/10 2:24 AM, Jan Vlčinský (CAD) wrote:Hi Option to have service like BaseX in the cloud would be very nice. I was dreaming about it too. On the other hand, I understand, that resources, being available at cloud solutions like Google Engine, AWS etc. are of quite different kind, that needed for efficient BaseX. When I see flashing of HD LED on my notebook, when performing bigger operations, I know, porting BaseX to any less disk efficient platform would kill the performance completely. For now, the only option in the cloud is sort of virtual computer (like AWS EC2 etc.) Jan PS: Christian - you see, providing great service creates even bigger demand :-).

In general, we have spent lots of effort and thoughts into our own storage architecture. It's one of the key factors for the efficiency of BaseX, so I'm not sure if switching to another database backend is such a good idea, not to mention transaction issues, etc. But I might be wrong.
