Have you had experience using Amazon's Simple Notification Service (SNS) for sending notifications?

Amazon Simple Notification Service (SNS) is a service for sending notifications and messages to distributed systems. Experience with SNS typically includes:

• Creating topics for grouping messages.
• Subscribing to topics via various protocols (email, SMS, HTTP/HTTPS, Lambda, etc.).
• Publishing messages to topics for distribution to subscribers.

An example of using SNS with Python and boto3:

import boto3

sns = boto3.client('sns')

topic_arn = 'arn:aws:sns:region:account-id:topic-name'

response = sns.publish(
    TopicArn=topic_arn,
    Message='Test notification',
    Subject='Notification subject'
)

print('Message ID:', response['MessageId'])

Such experience is useful for implementing notification systems and integrating microservices.
