My team at StackSearch and Qbox.io, an official Elasticsearch partner, have released a service for provisioning dedicated Elasticsearch clusters across all global data centers on Rackspace and AWS.
There is an easy configurator and price calculator for the resources, and one click deployment of one of six monitoring plugins, including Paramedic, Head, ElasticSearchHQ, BigDesk, Hammer, and Inquisitor. Uptime and availability is supported by the Qbox team and as official partners, we are enabled to sign you up for Elasticsearch's professional support offerings.
We welcome your feedback. http://qbox.io
Cheers, Mark
