The Lambda function already has an execution role, so the correct fix is toadd CloudWatch Logs permissions to that same role. AWS documentation lists the required permissions for a Lambda function to write logs: logs:CreateLogGroup, logs:CreateLogStream, and logs:PutLogEvents. A separate role for the S3 bucket would not help because Lambda uses its own execution role when it runs. An S3 bucket policy is unrelated to CloudWatch Logs logging. The logs:GetLogEvents permission is for reading logs, not writing them. Updating the existing execution role is the least-complex and correct solution.

Amazon SQS with Amazon ECS on AWS Fargate is the best managed architecture for containerized, loosely coupled message processing. SQS is a fully managed message queue that decouples distributed application components and scales without the operational burden of managing broker infrastructure. SNS can fan out messages to the SQS queue when publish-subscribe behavior is needed. ECS on Fargate runs containers without requiring the company to manage EC2 instances, Kubernetes worker nodes, or server capacity. Amazon MQ is useful when applications need traditional broker compatibility, but it does not provide the same virtually unlimited scaling model as SQS standard queues. EC2 Reserved Instances also violate the goal of fully managed infrastructure.

The data isfrequently accessed only for the first 30 daysand then israrely accessedbut must be retained for7 years. That pattern matchesAmazon S3 Standardfor the initial active period and thenS3 Glacier Deep Archivefor long-term retention at the lowest storage cost. AWS guidance positions Glacier Deep Archive for long-lived archive data that is accessed once or twice a year and is ideal for compliance-style retention. EFS and EBS are not cost-effective archival storage choices for this use case. S3 Standard-IA is cheaper than S3 Standard, but Glacier Deep Archive is more cost-optimized for multi-year rare access.
