Benefits of Amazon Simple Notification Service (SNS)

Message delivery services are provided by AWS (Amazon Web Services) via Amazon SNS (Simple Notification Service). Messages may also be sent to the clients or endpoints which subscribed to them. It is a highly available, durable, and secure messaging service that is completely managed.

In this blog post, we will explore what Amazon SNS is all about, its benefits, features, pricing policy, and much more. Let’s jump right into it. If you are looking for Amazon PPC management services to utilize Amazon SNS be sure to contact Amazon experts at Urtasker. They have extensive experience of more than ten years in handling these types of things. 

What is AWS SNS

Simple Notification Service is a component of Amazon SNS, which allows applications to communicate push messages to subscribers or other applications. The service provides complete management of both application to application (A2A) and person to person (A2P) messaging. Creating a Topic provides the capability of creating a logical communication channel and access point. Publishers can post messages on each topic, and subscribers can subscribe to receive notifications. Each topic has a unique name that identifies the SNS endpoint.

Amazon SNS has proven to be an effective tool in Amazon account management

Amazon SNS features

  • Scaling automatically. If a large number of messages are received, the engine automatically scales as a consequence.
  • Encryption of messages. Encryption protects messages from being read by unauthorized or untrusted individuals. In the process of being delivered to subscribing endpoints, the messages are decrypted.
  • Filtering of messages. By modifying this policy, a subscriber is able to receive only the notifications that are of interest to them.
  • Fan out the message. The process involves a message being sent to a topic and then replicating and pushing it to a plurality of endpoints. Asynchronous notification of events is enabled by Fanout, allowing for parallel processing.
  • Notifications for mobile devices. It can be activated from business logic within the cloud or user-driven actions within an application. Mobile push notifications can be delivered to iOS, Android, Fire OS, and Windows devices as well as Baidu devices at a low cost.
  • Messages are sent via SNS and email. As part of Amazon SNS, you have the option of sending text messages and emails (SMTP) from within the app.

AWS Simple Notification Service (SNS) Benefits

  • Instant delivery. Push-based delivery is the basis of this service. Once a message has been published on a particular subject, and the message has been delivered to multiple recipients, it is pushed.
  • Cost-effective. We are using an on-demand pay-as-you-go model, which means we will pay only when we use the resources, without having to pay in advance.
  • Adaptable. Multiple endpoints are supported. The message can be received by various endpoint types using different transport protocols, including email, SMS, Lambda, Amazon SQS, HTTP, etc.
  • Easy to use. The AWS Management Console is a web-based service that offers ease of usage of point-and-click convenience.
  • Designed for simplicity. With a System for Notifying Subscribers, subscribers can offload filtering logic, and publishers can offload routing logic. The SNS does not receive all the messages from the topic but rather sends the messages selectively to subscribers.

Topics covered by AWS SNS

AWS SNS topics fall into two categories:

  • Standard Topic
  • FIFO Topic

What is the difference between a standard topic and a FIFO topic?

  • The Standard Topic is used in many situations in which the order in which messages are delivered does not matter. FIFO Topics are used where the order of operations and events is critical in order to ensure smooth communication between applications.
  • Topics supported by Standard can send a near-limitless number of messages per second. As an alternative, the FIFO Topic supports a maximum of 300 messages per second. This is equivalent to approximately 10 megabytes per second.
  • It is common for a message to be delivered at least once. However, it is possible for the message to be delivered more than once. A FIFO topic, on the other hand, does not deliver duplicate messages, as it implements a priority system.
  • The maximum number of standard topics per account is 100K, and each topic can support up to 12.50M subscriptions, instead of the maximum number allowed in FIFO topics. FIFO topics support up to 1000 topics per account, while Subscriptions support up to 100 topics per account.

Pricing for AWS SNS

There is a generous and inexpensive free tier associated with Amazon Simple Notification Service. The price for renting a VNS is based on what you provide; all you need is to select the type of endpoint you are using. You will receive 1 million mobile push notifications every month for free. Afterward, each message delivered will be charged at only $0.5 per million, depending on the region where the message was delivered.

Security for Amazon SNS

  • SNS provides the option to encrypt topics to prevent messages from being viewed by unapproved parties. A server-side encryption process is used to accomplish this.
  • VPC Endpoints are supported via AWS PrivateLink by Amazon SNS. By using VPC Endpoints, we are able to send private messages to SNS topics without connecting to a public network.
  • You can control which content can be published to a topic, what endpoints are allowed to access it, and what conditions apply for publishing to a topic.
  • Messages passing through Amazon SNS can be tracked and analyzed using AWS X-Ray, allowing you to track and analyze messages on their way.

Clients of Amazon SNS

Clients of SNS include the following:

  • Subscribers
  • Publishers

Subscribers

When subscribed to a topic, subscribers receive notifications via one of the supported protocols such as Amazon SQS, email, or Lambda.

Publishers

It is not uncommon for a publisher to also be called a producer. Messages are produced and sent asynchronously to topics by communicating with subscribers in an asynchronous manner. Messages are produced and sent based on how subscribers communicate.

AWS SNS vs. SQS

We can decouple microservices, distributed systems, and serverless services with Amazon SQS (Simple Queue Service). With SQS, you can transport, store, and receive messages easily and without sacrificing volume or relying on other services. Amazon SNS and Amazon SQS work together conveniently.
