SNS can refer to two main concepts depending on the context:
1. Social Networking Service (SNS)
A social networking service is an online platform that enables people to connect, communicate, and build relationships with others who share similar interests, backgrounds, or real-life connections. Users create profiles, share content like photos and posts, and interact through messaging and commenting. Popular examples include Facebook, Instagram, LinkedIn, and Twitter (now X). These services facilitate social interaction beyond physical meetings and often operate on desktops and mobile devices. Their business models frequently rely on targeted advertising based on user data
2. Amazon Simple Notification Service (Amazon SNS)
Amazon SNS is a fully managed messaging service provided by Amazon Web Services (AWS). It uses a publish-subscribe (pub/sub) model where publishers send messages to a topic, and subscribers receive those messages through various endpoints such as email, SMS, mobile push notifications, HTTP/HTTPS endpoints, AWS Lambda, and more. It is designed for real-time message delivery, decoupling communication between distributed systems or applications, and supporting both application-to-application and application- to-person messaging. Amazon SNS is widely used for sending alerts, notifications, and messages reliably at scale
