Silver Lining is a cloud computing user group here in Boston. On February 10th, I'm presenting Tamale's Delta platform, which is cloud technology for financial applications.

Advent Tamale's approach is to extend the cloud services into the client's firewall using the Tamale Appliance. All the usual benefits of easy distribution and access are married with the complete privacy of on-site deployment.
