How to use IBM App Connect with AWS Lambda
AWS Lambda is an event-driven, serverless computing platform offered by Amazon Web Services (AWS). It allows you to run code for applications or backend services without provisioning or managing servers.
- App Connect Enterprise as a Service connector
-
Local
connector in containers (Continuous Delivery release) 12.0.5.0-r4 or later -
Local connector in containers (Long Term Support Cycle-2 release)
Supported product and API versions
To find out which product and API versions this connector supports, see Detailed System Requirements on the IBM Support page.
Connecting to AWS Lambda
Complete the connection fields that you see in the App Connect Designer page (previously the Catalog page) or flow editor. If necessary, work with your AWS Lambda administrator to obtain these values.
| Connection field | Description |
|---|---|
| Secret access key | The secret access key of your AWS Lambda account. Get the secret access key from the Security Credentials page in the AWS Management Console. |
| Access key ID | The access key ID of your AWS Lambda account. Get the access key ID from the Security Credentials page in the AWS Management Console. |
| Region | The region of your AWS Lambda instance, for example, us-east-1.
|
To obtain the connection values for AWS Lambda, see Obtaining connection values for AWS Lambda.
To connect to an AWS Lambda endpoint from the App Connect Designer Applications and APIs page for the first time, expand AWS Lambda, then click Connect. For more information, see Managing accounts.
Before you use the account that is created in App Connect in a flow, rename the account to something meaningful that helps you to identify it. To rename the account on the Applications and APIs page, select the account, open its options menu (⋮), then click Rename Account.
General considerations
Before you use App Connect Designer with AWS Lambda, take note of the following considerations:
- (General consideration) You can see lists of the trigger events and
actions that are available on the Applications and APIs page of the App Connect Designer.
For some applications, the events and actions depend on the environment and whether the connector supports configurable events and dynamic discovery of actions. If the application supports configurable events, you see a Show more configurable events link under the events list. If the application supports dynamic discovery of actions, you see a Show more link under the actions list.
- (General consideration) If you are using multiple accounts for an application, the set of fields that is displayed when you select an action for that application can vary for different accounts. In the flow editor, some applications always provide a curated set of static fields for an action. Other applications use dynamic discovery to retrieve the set of fields that are configured on the instance that you are connected to. For example, if you have two accounts for two instances of an application, the first account might use settings that are ready for immediate use. However, the second account might be configured with extra custom fields.
