If you are setting up multiple WSO2 products in a cluster, it is recommended to set up each product on a separate server. For example, WSO2 ESB is used for message mediation, so a considerable amount of processing happens in the ESB. The DSS does data service hosting and has a different architecture layer from the ESB. If you deploy both the ESB and DSS in the same instance/runtime, it can negatively impact the performance of both, and it also makes scaling difficult. However, you can set up hybrid servers (installing selected DSS features on top of the ESB and vice versa) using WSO2 products without the above performance concerns. |
