OTP in server farms

Abstract

Ericsson's OTP (Open Telecom Platform) offers a number of attractive features if you want to provide a variety of information services on a network with high availability, scalability, and extensibility. However, the major uses of OTP have been in closed, relay-rack systems, rather than in clusters of general-purpose servers. We describe issues we encountered while bringing up applications on OTP in the latter environment at a computer telephony company.
