The numbers of RCUs and systems listed are for reference only. For details about the number of resources (such as application flows, 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. Multiple connections can be established between a service system and a ROMA Connect instance.
  • Number of RCUs: The ROMA Compute Unit (RCU) is the capability compute unit of the new version. Each RCU can be allocated to different integration capabilities, including FDI, APIC, MQS, LINK, and composable applications. The performance specifications of each integration capability depend on the number of RCUs allocated. More RCUs indicate higher specifications.

Note that minimum RCUs and adjustments vary with the integration capability.

Specifications

The specifications of each integration capability of the new version vary with the number of allocated RCUs. Table 2 lists the specifications of each RCU.

  • The following performance data comes from lab tests and may differ from that in actual service scenarios.
  • Once FDI is enabled, the number of FDI tasks for both message and non-message data is fixed to 1000 and does not change with RCUs.
