Deploying and Clustering the API Manager

In a typical production environment, you set up the different API Manager components (API Publisher, Store, Gateway, Key Manager and Traffic Manager) in separate servers so that you can scale them independently. You also install multiple instances of a component in a cluster to ensure proper load balancing. When one node becomes unavailable or is experiencing high traffic, another node handles the requests.

For information on clustering, see Clustering WSO2 API Manager.
For information on deployment patterns, see API Manager Deployment Patterns.

Using email address as the username while clustering APIM

To enable using your email(e.g. admin@wso2.com) as your username when clustering APIM and IS, while doing master configurations, do the following.

Go to <APIM_HOME>/repository/conf/api-manager.xml. In the DataPublisher section under ThrottlingConfiguration section specify the username as admin@wso2.com@carbon.super. api-manager.xml accepts only configurations for the super tenant.

<Username>admin@wso2.com@carbon.super</Username>
