= Setting up cross-site with {jdgserver_name} {jdgserver_version_latest}
|
|
|
|
[role="_abstract"]
|
|
Use the following procedures for {jdgserver_name} {jdgserver_version_latest} to perform a basic setup of cross-site replication.
|
|
|
|
This example for {jdgserver_name} {jdgserver_version_latest} involves two data centers, `site1` and `site2`. Each data center consists of 1 {jdgserver_name} server and 2 {project_name} servers. We will end up with 2 {jdgserver_name} servers and 4 {project_name} servers in total.
|
|
|
|
* `Site1` consists of {jdgserver_name} server, `server1`, and 2 {project_name} servers, `node11` and `node12` .
|
|
|
|
* `Site2` consists of {jdgserver_name} server, `server2`, and 2 {project_name} servers, `node21` and `node22` .
|
|
|
|
* {jdgserver_name} servers `server1` and `server2` are connected to each other through the RELAY2 protocol and `backup` based {jdgserver_name}
|
|
caches in a similar way as described in the link:{jdgserver_crossdcdocs_link}[{jdgserver_name} documentation].
|
|
|
|
* {project_name} servers `node11` and `node12` form a cluster with each other, but they do not communicate directly with any server in `site2`.
|
|
They communicate with the Infinispan server `server1` using the Hot Rod protocol (Remote cache). See <<communication>> for more information.
|
|
|
|
* The same details apply for `node21` and `node22`. They cluster with each other and communicate only with `server2` server using the Hot Rod protocol.
|
|
|
|
Our example setup assumes that the four {project_name} servers talk to the same database. In production, we recommend that you use separate synchronously replicated databases across data centers as described in <<database>>.
