Integrate Amazon SNS with multiple AWS Cloud services to boost message handling, improve access control, enable event-driven processing, and automate resources. This integration optimizes performance, strengthens security, and streamlines operations.
- Amazon CloudWatch
-
Amazon CloudWatch provides monitoring and observability for Amazon SNS, helping you track message delivery, detect anomalies, and troubleshoot issues. With CloudWatch, you can:
-
Monitor Amazon SNS metrics such as the number of messages published, delivered, or failed across topics and subscriptions.
-
Set up CloudWatch Alarms to trigger automated actions when Amazon SNS metrics exceed predefined thresholds, such as high delivery failures or throttling.
-
Use CloudWatch Logs to capture Amazon SNS delivery status for messages sent to HTTP/S, Lambda, and Amazon SQS endpoints for debugging and auditing.
For more information, see Monitoring Amazon SNS topics using CloudWatch.
-
- Amazon SQS
-
Amazon SQS is a fully managed message queuing service that enables secure, durable, and scalable communication between distributed software components. It helps decouple application architecture by buffering messages, ensuring reliable delivery, and preventing system failures due to message loss. Amazon SQS integrates with Amazon SNS in the following ways:
-
Dead-letter queues – Amazon SNS can route undeliverable messages to an Amazon SQS dead-letter queue for troubleshooting and reprocessing.
-
Topic subscriptions – You can subscribe an Amazon SQS queue to an Amazon SNS topic, allowing Amazon SNS to fan out messages to multiple consumers using Amazon SQS.
-
FIFO queue support – Amazon SQS FIFO queues can be subscribed to Amazon SNS FIFO topics, ensuring strict message ordering and exactly-once processing. Standard Amazon SQS queues can also subscribe to Amazon SNS topics but do not guarantee ordered message delivery or deduplication.
-
- AWS CloudFormation
-
AWS CloudFormation automates the provisioning and management of AWS resources, including Amazon SNS topics and subscriptions, using infrastructure as code (IaC). With AWS CloudFormation, you can:
-
Define Amazon SNS topics, subscriptions, and permissions in a reusable, version-controlled template.
-
Ensure consistent deployment of Amazon SNS resources across multiple AWS accounts and Regions.
-
Update or modify Amazon SNS configurations using change sets without manual intervention.
For more information, see the AWS CloudFormation User Guide.
-
- AWS CloudTrail
-
CloudTrail provides visibility into API activity for Amazon SNS, helping you monitor and audit access to Amazon SNS topics, subscriptions, and messages. With CloudTrail, you can:
-
Track API calls made to Amazon SNS, including who accessed or modified topics, subscriptions, and permissions.
-
Detect unauthorized or unexpected activity by analyzing logs for security and compliance purposes.
-
Integrate with Amazon CloudWatch or AWS Security Hub to create alerts based on unusual Amazon SNS actions.
For more information, see the Logging AWS SNS API calls using AWS CloudTrail.
-
- AWS Lambda
-
AWS Lambda is a serverless compute service that automatically runs your code in response to events, eliminating the need to provision or manage servers. It allows you to build event-driven applications that scale automatically and execute in a highly available compute environment.
Amazon SNS integrates with Lambda by allowing you to subscribe a Lambda function to an Amazon SNS topic. When an Amazon SNS topic receives a message, it can trigger the Lambda function, enabling real-time processing, automation, and application logic execution. This integration is commonly used for:
-
Event-driven processing – Automatically trigger functions in response to Amazon SNS messages.
-
Data transformation – Modify or filter Amazon SNS messages before forwarding them to other services.
-
Automated workflows – Process notifications for application alerts, system monitoring, or event orchestration.
-
- AWS Identity and Access Management (IAM)
-
IAM provides secure access control for AWS resources, allowing you to manage who can access your Amazon SNS topics, what actions they can perform, and under what conditions. With IAM, you can:
-
Authenticate users and services before they can interact with Amazon SNS topics.
-
Define fine-grained permissions to specify which Amazon SNS topics users or roles can publish to, subscribe to, or manage.
-
Use identity-based policies to enforce security best practices, such as restricting access to specific AWS accounts, IP addresses, or conditions.
For more information, see Using identity-based policies with Amazon SNS.
-
- AWS Key Management Service (AWS KMS)
-
AWS KMS enhances the security of Amazon SNS by enabling server-side encryption (SSE) for message confidentiality. With AWS KMS, you can:
-
Encrypt Amazon SNS messages at rest using AWS-managed or customer-managed encryption keys (CMKs).
-
Control access to Amazon SNS topics by defining fine-grained key policies that restrict who can publish or subscribe.
-
Ensure compliance with security and regulatory requirements by auditing key usage through AWS CloudTrail.
For more information, see Managing Amazon SNS encryption keys and costs.
-
- AWS X-Ray
-
X-Ray provides tracing for Amazon SNS, helping you analyze and debug the flow of messages through your event-driven architecture. With X-Ray, you can:
-
Trace Amazon SNS message delivery across multiple AWS services, such as Lambda, Amazon SQS, and HTTP/S endpoints.
-
Identify latency bottlenecks by visualizing how long messages take to be published, delivered, and processed.
-
Detect errors and retries in Amazon SNS message flows to troubleshoot failed deliveries or slow processing times.
For more information, see Active tracing in Amazon SNS.
