erps v0.4.0 Erps View Source
Erps is an OTP-compliant remote protocol service
The general purpose of Erps is to extend the GenServer primitives over public networks using TLS authentication and encryption without using OTP standard distribution, for cases when
- latency, reliability, or network toplogy properties make using erlang distribution unfavorable or unreliable
- you prefer to use erlang distributed clusters strictly contain members of a given type, and have an orthogonal channel for cluster-to-cluster communication.
Erps is an asymmetric protocol, which means there are distinct roles for
client and server. An Erps client is a 'dumb proxy' for a remote GenServer,
forwarding all of its call/2
and cast/2
requests to the Erps server.
Security model
Erps currently presumes that once authenticated, both ends of the Erps connection are trusted, and provides only basic security measures to protect the server and the client.
In particular, one of the strategies, Erps.Transport.OneWayTls
, is still
in-progress but should be considered experimental and insecure. Updates
to improve the security model of this stratgy are welcome.
Distribution and Worker pools
There are no provisions for supporting out-of-the-box 'smart' distribution defaults or smart worker pool defaults, but this is planned.
Examples
Examples on how to set up basic clients and servers are provided in
in the documentation for Erps.Client
and Erps.Server
