In order to communicate by both application-to-application (A2A) and application-to-person (A2P), Amazon Simple Notification Service (Amazon SNS) provides a fully managed messaging service.
An important feature of A2A is that it offers push-based sessions that are many-to-many, allowing high-throughput, high-volume messaging, Microsoft devices, and also email notifications. Additionally, it provides serverless applications and microservices. You can decide how you want your notifications to be sent to your users through Amazon SNS. SNS for Amazon is available in more than 200 countries, while mobile push notifications are available for Amazon, Apple, Android, Baidu, and Yahoo
Let’s discuss in detail its features, benefits, pricing, and how to activate it. If you still need more guidance on how to start the Amazon SNS service, contact us at Urtasker. We are an Amazon marketing company providing all sorts of services related to the eCommerce industry for existing sellers.
What is Amazon Web Services SNS?
AWS SNS sends messages to its endpoints using a Publisher-Subscriber model as indicated previously. By using Amazon SNS, you can send your message via email or mobile SMS to numerous subscribers or endpoints.
A publisher, also called a producer or a sender creates and sends messages to an SNS channel using their Amazon account management settings. As a subscriber, however, you receive messages that you publish on the SNS service through support for HTTP/ HTTPS, Amazon SQS, AWS Lambda, and other network protocols.
Below is a description of the various steps taken by AWS SNS.
AWS SNS performs the following steps in its workflow:
- Initial notification is sent out by the publisher to all subscribers who need to receive notifications.
- Messages published on the SNS are sent to the following key components in order to be viewed on the SNS:
SNS Topic. A message can be filtered out to make sure it is only sent to the appropriate recipients. Upon creating an SNS topic, you will be able to establish an interface for subscribers as an AWS developer. Subscribers will be notified whenever a brand-new message is posted on their topic of choice.
Filtering of messages. The SNS messages are decoupled from each other and entered into the message filter using these mechanisms, after which the messages are further filtered by the subscriber’s policy selection. After the policy check and permissions are confirmed, a message will be sent to a specific subscriber.
- Subscription queues or microservices are used to deliver the message to the subscriber. If you want to receive the messages, you would need to provide valuable information that would include your email address, URL address, and your phone number.
Among the various SNS message types widely used are:
- Alerts related to applications and systems. Notifications are automatically sent to specific users upon reaching predetermined thresholds, either via SMS or email.
- Send an email or text message in advance. Either of these methods can be used to communicate with individuals or groups. For instance, newspaper subscribers are sent notifications of new articles.
- Notifications are sent via mobile device. Mobile apps receive notifications directly from the device. Among the notifications are those that inform the app user when an update is available for the app.
What are the advantages of Amazon SNS?
There are four key benefits offered by Amazon SNS.
- Reliability is high
There are several regions across the Amazon Web Services network where Amazon SNS messages are stored. Due to this change, messages can now be distributed across multiple geographical regions simultaneously, resulting in a more reliable service. The extensive network of AWS data centers also makes it possible for businesses to send messages anytime, anywhere, through AWS.
As well as Amazon SNS, AWS Lambda and Amazon SQS also support messaging through Amazon SNS. Message delivery to subscriber endpoints will be retried with the SNS service, and messages can be moved to dead-letter queries (DLQs).
- Scalability by automatic means
It is possible to dynamically scale up or down the number of messages you send or receive using the Amazon SNS service. Amazon SNS utilizes Amazon’s AWS cloud platform as a scaling tool for this purpose.
Amazon SNS is not only designed to be scalable but also to support high rates of throughput along with a variety of traffic patterns as well. Amazon SNS enables you to organize your work needs by providing you with capacity planning capabilities to decide how much of your bandwidth can be used. It is also worth noting that, for businesses to use this service, they do not need to purchase any software upfront, nor do they require any additional software.
- Filtering of messages
When you use the AWS SNS service, you are able to remove the subscriber’s filtering functionality and simplify your overall messaging architecture. The messages will also be routed through the publisher instead of the subscriber. An SNS service filters messages to ensure subscribers only see information relevant to them. Instead of receiving all information published within the SNS topic, subscribers receive only messages that hold interest to them.
- Assurance of security
SNS topic owners can specify the types of protocols that are used for a topic according to the topic-related policies. A topic also specifies which users are allowed to publish and subscribe to it. There are also security measures like limiting how many messages you send each day and keeping your OTP messages safe from unauthorized access.
Amazon SNS also protects your data with message encryption. In order to publish private messages to SNS topics, you must be based on an Amazon VPC subnet. With PrivateLink, you can use any Amazon Virtual Private Cloud (VPC) subnet to share messages privately.
Pricing for Amazon Simple Notification Services
There are no upfront costs associated with Amazon SNS. If you publish and deliver notifications, and if you manage topics or subscriptions through APIs, you are charged based on how many messages you send. Endpoints offer different pricing for notification delivery. With Amazon SNS free tier, for example, you can get started for free.
SNS can be used for what?
Keeping an eye on the alert notification system.
Monitor the failure events in a complex system to identify the types and complexity of failure events and to route information about them to the appropriate people. They can occur on the system level or at the application level.
Distribution of news
If a website, a topic on Twitter, or a feed in an RSS reader changes, then you should pay attention. Subscriptions will have the ability to choose which topics they would like to receive updates about. They will be notified of changes in one news topic per change.
Conclusion
You may deliver the right message(s) to subscribers or endpoints through the Amazon Simple Notification Service (SNS). Send push messages to distributed systems, microservices, and serverless applications using Amazon SNS’ publisher-subscriber model. We hope this article helps you understand what Amazon SNS is and how it can benefit your business.
