12.2. Running the Gateway

To run the gateway, simply deploy one (or more) of the predefined profiles to a Fabric container. The following gateway profiles are provided:

gateway-mq: Profile for a messaging gateway (for accessing Apache ActiveMQ brokers in the fabric).
gateway-http: Profile for a HTTP gateway (for Web applications or Web services).

There are two main deployment strategies for a gateway:

Run the gateway on each machine that needs to discover services and communicate with it through localhost. In this case, you do not need to hard code any host names in your messaging or Web clients and the connection to the gateway on localhost is nice and fast.
Run the gateway on one or more known hosts using DNS or VIP load balancing (mapping host names to machines). In this case, you can use a fixed host name for all your services.
