What is Amazon Cloud Watch?

Amazon CloudWatch is a monitoring and observability service provided by Amazon Web Services (AWS). It allows users to collect and track metrics, monitor log files, set alarms, and automatically react to changes in AWS resources. CloudWatch helps users gain insights into the performance and health of their applications, infrastructure, and services running on AWS.

What is Amazon SNS?

Amazon Simple Notification Service (Amazon SNS) is a fully managed messaging service provided by Amazon Web Services (AWS). It enables you to send notifications to a variety of endpoints such as email, SMS, HTTP, and more. SNS supports both pub/sub (publish/subscribe) and push notification models, making it easy to send messages or notifications to a large number of subscribers or individual recipients.
