Amazon Simple Notification Service

Amazon Simple Notification Service (SNS) is a fully managed messaging service provided by Amazon Web Services (AWS) that enables the decoupling and scaling of microservices, distributed systems, and serverless applications. It allows for the creation of topics, which act as communication channels where publishers can send messages and subscribers can receive them, supporting multiple protocols such as HTTP/HTTPS, email, SMS, and AWS Lambda functions. This service is particularly beneficial for developers and businesses looking to implement scalable and reliable messaging solutions within their AWS infrastructure.
