AWS Lambda now supports SASL/PLAIN authentication for functions triggered from self-managed Apache Kafka
AWS Lambda functions that are triggered from self-managed Apache Kafka topics can now access usernames and passwords secured by AWS Secrets Manager using SASL/PLAIN, a simple username/password authentication mechanism that is typically used with TLS for encryption to implement secure authentication. This is in addition to SASL/SCRAM, which is already supported on Lambda. To get started, customers who select Apache Kafka as the event source for their Lambda function can choose SASL/PLAIN as their authentication mechanism, and select their credentials from Secrets Manager on the AWS Management Console, AWS CLI or AWS SDK for Lambda. This feature requires no additional charge to use, and is available in all AWS Regions where self-managed Apache Kafka is supported as an event source for AWS Lambda. To learn more about using SASL/PLAIN authentication for your Lambda functions triggered from Amazon MSK topics, read the Lambda Developer Guide.
