Solution architecture

IBM® App Connect Enterprise as a Service is deployed across multiple availability zones in each Amazon Web Services (AWS) region.

The following diagram represents the App Connect Enterprise as a Service architecture.
The diagram is described in the surrounding text
Management functions and integration workloads are separated into a control plane and a data plane. Both planes are distributed across three availability zones for high availability. The architecture supports connectivity from enterprise networks, public networks, and customer accounts.

Available regions

AWS hosts instances of App Connect Enterprise as a Service in Regions, which are geographic areas. App Connect Enterprise as a Service is available in the following regions.
  • us-east-1 (North Virginia, US East)
  • eu-west-2 (London, Europe)
  • eu-central-1 (Frankfurt, Europe)
  • ap-southeast-2 (Sydney, Asia Pacific)
Each AWS region contains three or more isolated Availability Zones, which provide high availability within a region. For more information, see Regions and Availability Zones in the AWS documentation.
App Connect Enterprise as a Service resources run in virtual private clouds (VPCs). One VPC contains a control plane, which provides the App Connect Designer authoring tool, and management of users and deployed integrations. Another VPC contains a data plane, which hosts the runtimes where your integrations run. To meet your organization’s data residency requirements, you can choose the region where you provision each instance of App Connect Enterprise as a Service.
Note: Some regions contain both a control plane and a data plane. However, the three Asia Pacific regions share a control plane in Sydney. When you provision an instance of App Connect Enterprise as a Service in any of these Asia Pacific regions, the control plane is hosted in Sydney, and the data plane is hosted in your chosen region.
