We are in a world where we need to spread our words and stories to as many people as we can. Since everybody gets most of their information through mobile phones in this digital era, it has become a new haven for businesses to reach the people. Now, a business can utilize AWS SNS to send SMS messages to the SMS-enabled devices on a very large scale and reach as many eyes as one would want. You can publish messages directly to the phone numbers for these devices.
Not only can you reach out to practically unlimited length, but you can also do so while having total control over whether the message is optimized for cost or reliable delivery.
If we look into the workings of the service, each SMS message can contain up to 140 bytes, and the character limit depends on the encoding scheme. For example, an SMS message can contain:
If you publish a message that exceeds the size limit, AWS SNS sends it as multiple messages, each fitting within the size limit. Messages are not cut off in the middle of a word but on whole-word boundaries. The total size limit for a single SMS publish action is 1600 bytes. (Read:- What is AWS Lambda?)
Amazon Simple Notification Service (SNS) is a fully managed messaging service for both system-to-system and app-to-person (A2P) communication. It enables you to communicate between systems through publish/subscribe (pub/sub) patterns that enable messaging between decoupled microservice applications or to communicate directly to users via SMS, mobile push, and email.
The system-to-system pub/sub functionality provides topics for high-throughput, push-based, many-to-many messaging. Using Amazon SNS topics, your publisher systems can fanout messages to a large number of subscriber systems or customer endpoints including Amazon SQS queues, AWS Lambda functions, and HTTP/S, for parallel processing. The A2P messaging functionality enables you to send messages to users at scale using either a pub/sub pattern or direct-publish messages using a single API.
