What makes AWS SNS (also known as Simple Notification Service) a preferred choice for business?
With AWS SNS, users can easily send SMS or text messages to recipients in more than 200 countries without any minimum or upfront costs. Since it’s a cloud-based service, you only pay for the exact amount of usage you need, making it an even more attractive option.
SNS, which stands for Simple Notification Service, is a web service that manages and coordinates the sending and delivery of messages to subscribed clients or endpoints.
Simple Notification Service
SNS also supports push notifications and offers both First-in, First-out, and Standard services. Additionally, it has a distinctive encryption feature that lets you secure sensitive data in encrypted topics.
Enlisted below will be several key terminologies you need to grasp for a better understanding of SNS Software:
- Topic: A picked topic name will appear as the topic’s showcase title.
- Publisher: Publishers or producers generate messages that are then transmitted to the SNS, which acts as a virtual gateway or entry point.
- Subscriber: Subscribers, such as web servers, email addresses, Amazon SQS queues, and AWS Lambda functions, receive notifications or messages from SNS via various protocols, including Amazon SQS, email, Lambda, HTTPS, and SMS.
Types of SNSs’ Topic:
A created subject is not susceptible to any possible future modifications.
There is a range of SNSs options to choose from.
For starters, there’s the:
- Highest publish/second throughput.
- Subscription protocols include SQS, Lambda, HTTP, SMS, email, and endpoints for mobile applications.
- Message ordering is well-mended
- The system can handle many messages.
- Subscription options include SQS, Lambda, HTTP, SMS, email, and mobile app endpoints.
FIFO (First-in, First-out):
- Ordering of strictly maintained messages
- Delivery of messages only once.
- High rate, up to 300 publishes per second
- SQS-applied Subscription guidelines
Below is a list of some of the SNS messages that are under common transmission.
- Application & System Alerts: If certain thresholds are reached, specific users will get automatic notifications via email or text message.
- Push email or text messaging: are either grouped or single messaging
Eg: News articles sent to the subscription-based readership
- Mobile Push notifications: directly sent to mobile applications
Eg: Notifications informing users about available app updates that they can install – “Update Installations” or battery warnings…
How It Works:
AWS SNS uses the Publisher-Subscriber model to send messages to its endpoints. Using Amazon SNS, you can filter the messages to a larger number of subscribers or endpoints through mobile messages, SMS, and email.
- Also known as a producer, publishers create and send messages to the AWS SNS service.
- Subscribers, on the other hand, receive published messages from the SNS service over supported network protocols like Amazon SQS, AWS Lambda, or HTTP/ HTTPS.
Shown below is an illustration of the various execution steps by AWS SNS.
Here are the exact implementation workflow steps by AWS SNS:
1) First, the publisher sends out the notifications in requirements that are to be on delivery to subscribers.
2) The messages are then on delivery to the SNS service, which has the following key components:
- SNS Topic – filter out the messages that have to be sent to different subscribers. As an AWS developer, you first need to create an SNS topic that acts as the access point for subscribers. Using the topic, subscribers can receive message notifications on their subject of selection.
- Message Filter – After being decoupled using topics, the SNS messages enter the message filter, which further filters the messages based on the subscriber’s selected policy. Post the policy checking and permissions, the messages are finally sent to the respective subscribers.
3) The subscriber receives the message through subscribing queues or microservices. Subscribers provide useful information such as URL address, email address, or phone number in order to receive the message.
