The numbers of connections and systems listed are for reference only. For details about the number of resources (such as data integration tasks, APIs, and message topics) that can be created, see Quota Limits. To ensure the performance of ROMA Connect, create and use resources within the specified specifications.

  • Number of systems: A system refers to a user's service system, and the number of systems refers to the number of service systems interconnecting with a ROMA Connect instance. You can set up multiple connections between a service system and a ROMA Connect instance.
  • Number of connections: A connection refers to an interaction between a service system and ROMA Connect. The number of connections varies depending on the functional module in ROMA Connect that you want to connect. The following table describes the mappings between the number of resources and the number of connections.
