A Ct would like to test Afaria as its mobile management platform. In its
architecture, there is a Proxy server between the headquarter and its county
offices. Since Afaria Server Farm can configure many Afaria slave servers,
they are thinking to deploy slave servers in its county offices. The
difficulty is the communication between Master Afaria server and slave
servers should be HTTPS and Proxy Server (reverse proxy). We know Afaria
clinet can communicate with Afaria Server though HTTPS and Proxy Server.
Does it also work for Master and Slave Servers?

Jencheng,
No. The Afaria Administrator web console does not currently support
SSL. We have never heard of anyone attempting to implement it this way
either (I am referring to having an Afaria Farm spanned across an Internet
connection using Reverse Proxy.) If the remote sites have an Internet
connection, then why not just have the clients connect over the internet to
a centralized Afaria Farm via SSL/Reverse Proxy type connection?

Distributed implementations that we have seen always require a very
reliable high speed connection, typically a private (secure) network (WAN).
This due to the amount of SQL traffic that will be seen in larger, high
volume/load, environments and also that there is a requirement that the
database MUST always be available to the Afaria 5.x Server (Master or
Slave). If the database connection is lost, in an Afaria 5.x Server will
ultimately crash.

Christopher,

I got your point. In Afaria presentation slides, it mentioned about
Distributed Scenario of Afaria server farm. Master and several slave servers
can be configured in a distributed environment through WAN/VAN/Internet.

The request is from the customer because of bureaucracy. The headquarter do
not want to maintain local office used servers. I will convince them about
the reality.

Jencheng,
Another option would be to provide each office a stand alone Afaria
Server/Administrator install. Since the coporate culture dictates that they
do not want to support the local offices, then why would they need a central
Afaria database? If t
they do want a central database, the could potentially replicate each site
offices database to central database server, then build a
process/application that merges all the desired data into one central/common
database for reporting purposes.
We have seen this methodology of implementing Afaria infrastructure work
successfully.

Thanks,
Chris
