Service Connector Hub Overview

Service Connector Hub is a cloud message bus platform that offers a single pane of glass for describing, executing, and monitoring movement of data between services in Oracle Cloud Infrastructure.

Note

Service Connector Hub is not available in Oracle Cloud Infrastructure Government Cloud realms.

How Service Connector Hub Works

Service Connector Hub orchestrates data movement between services in Oracle Cloud Infrastructure.

Data is moved using service connectors. A service connector specifies the source service that contains the data to be moved, optional tasks, and the target service for delivery of data when tasks are complete. An optional task might be a function task to process data from the source or a log filter task to filter log data from the source.

Service Connector Hub Concepts

The following concepts are essential to working with Service Connector Hub.

service connector: The definition of the data to be moved. Specifies a source service , target service , and optional tasks .
source: The service containing the data to be moved according to specified tasks . Examples include Logging and Streaming.
target: The service receiving the data from the source, according to specified tasks . A given target service may process, store, or deliver received data. Functions processes received data while Logging Analytics, Monitoring, Object Storage, and Streaming store received data. Notifications delivers received data.
task: Optional filtering or other processing to apply to the data before moving it from the source service to the target service . Examples include a function task to process data from the source and a log filter task to filter log data from the source.

trigger: The condition that must be met for the service connector to run. Currently the trigger is continuous; that is, service connectors run continuously.

Flow of Data

When a service connector runs, it receives data from the source service, completes optional tasks on the data (such as filtering), and then moves the data to the target service.

This image shows how Service Connector Hub moves data from the source service to the target service, with tasks applied in between.

Tasks: While a function task applies to any source, a log filter task applies to a Logging source only.

Availability

The Service Connector Hub service is available in all Oracle Cloud Infrastructure commercial regions. See About Regions and Availability Domains for the list of available regions, along with associated locations, region identifiers, region keys, and availability domains.

Resource Identifiers

Most types of Oracle Cloud Infrastructure resources have a unique, Oracle-assigned identifier called an Oracle Cloud ID (OCID). For information about the OCID format and other ways to identify your resources, see Resource Identifiers.

Ways to Access Service Connector Hub

You can access the Service Connector Hub service using the Console (a browser-based interface) or the REST API. Instructions for the Console and API are included in topics throughout this guide. For a list of available SDKs, see Software Development Kits and Command Line Interface.

Console: To access Service Connector Hub using the Console, you must use a supported browser. You can use the Console link at the top of this page to go to the sign-in page. You will be prompted to enter your cloud tenant, your user name, and your password. Open the navigation menu and click Analytics & AI. Under Messaging, click Service Connector Hub.

You can also access Service Connector Hub from the following services in the Console:

Logging: Open the navigation menu and click Observability & Management. Under Logging, click Service Connectors.
Streaming: Open the navigation menu. Under Solutions and Platform, click Analytics, click Streaming, and then click Service Connectors.

API: To access Service Connector Hub through API, use Service Connector Hub API. To access this API using the Command Line Interface (CLI), use the designation for service connectors: oci sch service-connector. For more details about the CLI, see Command Line Reference for Service Connector Hub.

Authentication and Authorization

Each service in Oracle Cloud Infrastructure integrates with IAM for authentication and authorization, for all interfaces (the Console, SDK or CLI, and REST API).

An administrator in your organization needs to set up groups , compartments , and policies that control which users can access which services, which resources, and the type of access. For example, the policies control who can create new users, create and manage the cloud network, launch instances, create buckets, download objects, etc. For more information, see Getting Started with Policies. For specific details about writing policies for each of the different services, see Policy Reference.

If you’re a regular user (not an administrator) who needs to use the Oracle Cloud Infrastructure resources that your company owns, contact your administrator to set up a user ID for you. The administrator can confirm which compartment or compartments you should be using.

Access to Service Connector Hub

Administrators: For common policies that give groups access to Service Connector Hub, see Allow a group to manage service connectors.

Access to Source, Task, and Target Services

Note

Ensure that any policy you create complies with your company guidelines.

To move data, your service connector must have authorization to access the specified resources in the source , task , and target services. Some resources are accessible without policies.

Default policies providing the required authorization are offered when you use the Console to define a service connector. These policies are limited to the context of the service connector. You can either accept the default policies or ensure that you have the proper authorizations in group-based policies.

Default Policies

This section details the default policies offered when you create or update a service connector in the Console.

Functions (Task or Target)

Applies when the service connector specifies a function task or selects Functions as its target service.

Where this policy is created: The compartment where the function resides. The function is selected for the task or target when you create or edit service connector.

allow any-user to use fn-function in compartment id <target_function_compartment_ocid>
where all {
    request.principal.type='serviceconnector',     
    request.principal.compartment.id='<serviceconnector_compartment_ocid>'
}
allow any-user to use fn-invocation in compartment id <target_function_compartment_ocid>
where all {
    request.principal.type='serviceconnector',     
    request.principal.compartment.id='<serviceconnector_compartment_OCID>'
}

Logging (Source, Task)

No default policies are offered because they are not required for access to resources in the Logging service, whether defined as the source or task (log filter task ) of a service connector.

Logging Analytics (Target)

Applies when the service connector specifies Logging Analytics as its target service.

Where this policy is created: The compartment where the log group resides. The log group is selected or entered for the target when you create or edit a service connector.

allow any-user to use loganalytics-log-group in compartment id <target_log_group_compartment_OCID>
where all {
    request.principal.type='serviceconnector', 
    target.loganalytics-log-group.id=<log_group_OCID>, 
    request.principal.compartment.id=<serviceconnector_compartment_OCID>
}

Monitoring (Target)

Applies when the service connector specifies Monitoring as its target service.

Where this policy is created: The compartment where the metric namespace resides. The metric namespace is selected or entered for the target when you create or edit a service connector.

allow any-user to use metrics in compartment id <target_metric_compartment_OCID>
where all {
    request.principal.type='serviceconnector',
    target.metrics.namespace='<metric_namespace>',
    request.principal.compartment.id='<serviceconnector_compartment_OCID>'
}

Notifications (Target)

Applies when the service connector specifies Notifications as its target service.

Where this policy is created: The compartment where the topic resides. The topic is selected for the target when you create or edit service connector.

allow any-user to use ons-topics in compartment id <target_topic_compartment_OCID>
where all {
    request.principal.type= 'serviceconnector',
    request.principal.compartment.id='<serviceconnector_compartment_OCID>'
}

Object Storage (Target)

Applies when the service connector specifies Object Storage as its target service.

Where this policy is created: The compartment where the bucket resides. The bucket is selected for the target when you create or edit service connector.

allow any-user to manage objects in compartment id <target_bucket_compartment_OCID> 
where all {
    request.principal.type='serviceconnector',
    target.bucket.name='<bucket_name>',          
    request.principal.compartment.id='<serviceconnector_compartment_OCID>'
}

Streaming (Source)

Applies when the service connector specifies Streaming as its source service.

Where this policy is created: The compartment where the stream resides. The stream is selected for the source when you create or edit service connector.

allow any-user to {STREAM_READ, STREAM_CONSUME} in compartment id <target_bucket_compartment_OCID>
where all {
    request.principal.type='serviceconnector',
    target.stream.id='stream_id',
    request.principal.compartment.id='<serviceconnector_compartment_OCID>'
}

Streaming (Target)

Applies when the service connector specifies Streaming as its target service.

Where this policy is created: The compartment where the stream resides. The stream is selected for the target when you create or edit service connector.

allow any-user to use stream-push in compartment id <target_stream_compartment_OCID>
where all {
    request.principal.type='serviceconnector',
    target.stream.id='<stream_OCID>',
    request.principal.compartment.id='<serviceconnector_compartment_OCID>'
}

When reviewing group-based policies for required authorization to access a resource (service) in a service connector, reference the default policy offered for that service in that context (see previous section) or see the policy details for the service at Policy Reference.

Note

To accept default policies for an existing service connector, simply edit the service connector. The default policies are offered whenever you create or edit a service connector. The only exception is when the exact policy already exists in IAM, in which case the default policy is not offered.

For troubleshooting information, see Troubleshooting Service Connectors.

Limits on Service Connector Hub

See Service Connector Hub Limits. Logging Limits apply when service connectors read from Logging. Streaming Limits apply when service connectors read from Streaming.

See Service Limits for a list of applicable limits and instructions for requesting a limit increase. To set compartment-specific limits on a resource or resource family, administrators can use compartment quotas.
