Chapter 9. Multi-tenancy

Multi-tenancy allows accessing multiple containers as shown below:

Currently there are two supported protocols for accessing the data - using Hot Rod client and using REST interface.

9.1. Using REST interface

Multi-tenancy router uses URL prefixes to separate containers using the following template: https://<server_ip>:<server_port>/rest/<rest_connector_name>/<cache_name>/<key>. All HTTP operations remain exactly the same as using standard rest-connector.

The REST connector by default support both HTTP/1.1 and HTTP/2 protocols. The switching from HTTP/1.1 to HTTP/2 procedure involves either using TLS/ALPN negotiation or HTTP/1.1 upgrade procedure. The former requires proper encryption to be enabled. The latter is always enabled.

9.2. Using Hot Rod client

Multi-tenant routing for binary protocols requires using a standard, transport layer mechanism such as SSL/TLS Server Name Indication. The server needs to be configured to support encryption and additional SNI routing needs to be added to the router-connector.

In order to connect to a secured Hot Rod server, the client needs to use configuration similar to this:

ConfigurationBuilder clientBuilder = new ConfigurationBuilder();
clientBuilder
    .addServer()
        .host("127.0.0.1")
        .port(hotrodServer.getPort())
     .security()
        .ssl()
           .enabled(sslClient)
           .sniHostName("hotrod-1") // SNI Host Name
           .trustStoreFileName("truststore.jks")
           .trustStorePassword("secret".toCharArray());
remoteCacheManager = new RemoteCacheManager(clientBuilder.build());

ConfigurationBuilder clientBuilder = new ConfigurationBuilder();
clientBuilder
    .addServer()
        .host("127.0.0.1")
        .port(hotrodServer.getPort())
     .security()
        .ssl()
           .enabled(sslClient)
           .sniHostName("hotrod-1") // SNI Host Name
           .trustStoreFileName("truststore.jks")
           .trustStorePassword("secret".toCharArray());
remoteCacheManager = new RemoteCacheManager(clientBuilder.build());

The Multi-tenant router endpoint works as a facade for one or more REST/Hot Rod connectors. Its main purpose is to forward client requests into proper container.

In order to properly configure the routing, socket-binding attributes of other connectors must be disabled and additional attribute name must be used as shown below:

<rest-connector name="rest-1" cache-container="local"/>
<rest-connector name="rest-2" cache-container="local"/>
<hotrod-connector name="hotrod-1" cache-container="local" />
<hotrod-connector name="hotrod-2" cache-container="local" />

<rest-connector name="rest-1" cache-container="local"/>
<rest-connector name="rest-2" cache-container="local"/>
<hotrod-connector name="hotrod-1" cache-container="local" />
<hotrod-connector name="hotrod-2" cache-container="local" />

The next step is to add a new router-connector endpoint and configure how other containers will be accessed. Note that Hot Rod connectors require using TLS/SNI and REST connectors require using prefix in the URL:

<router-connector hotrod-socket-binding="hotrod" rest-socket-binding="rest" keep-alive="true" tcp-nodelay="false" receive-buffer-size="1024" send-buffer-size="1024">
    <hotrod name="hotrod-1" >
        <sni host-name="hotrod-1" security-realm="SSLRealm1"/>
    </hotrod>
    <hotrod name="hotrod-2" >
        <sni host-name="hotrod-2" security-realm="SSLRealm2"/>
    </hotrod>
    <rest name="rest-1">
        <prefix path="rest-1" />
    </rest>
    <rest name="rest-2">
        <prefix path="rest-2" />
    </rest>
</router-connector>

<router-connector hotrod-socket-binding="hotrod" rest-socket-binding="rest" keep-alive="true" tcp-nodelay="false" receive-buffer-size="1024" send-buffer-size="1024">
    <hotrod name="hotrod-1" >
        <sni host-name="hotrod-1" security-realm="SSLRealm1"/>
    </hotrod>
    <hotrod name="hotrod-2" >
        <sni host-name="hotrod-2" security-realm="SSLRealm2"/>
    </hotrod>
    <rest name="rest-1">
        <prefix path="rest-1" />
    </rest>
    <rest name="rest-2">
        <prefix path="rest-2" />
    </rest>
</router-connector>

With the following configuration, Hot Rod clients will access hotrod-1 connector when using SNI Host Name "hotrod-1". REST clients will need to use the following URL to access "rest-1" connector - https://<server_ip>:<server_port>/rest/rest-1.
