"The Amazon documentation is comprehensive and, unlike many other products, clearly states what you can use Amazon SNS for. Several pages are dedicated to explaining in detail how FIFO topics (which provide superior quality of service) work. Overall, the developer guide might not deserve its name since it’s mostly a product guide. Its primary focus is on explaining things conceptually and performing operations in the AWS console. There’s a limited number of code snippets embedded in the dev guide, and only in a couple of languages. Fortunately, the API documentation is very detailed, although it’s inconsistently presented across languages, and you won’t always find code snippets in your language of choice. The official tutorials are poor, only cover some basics, and focus almost entirely on the AWS console."

Functionality5 / 5

"Getting started with the SNS console as a new user can be a confusing and slightly painful experience (unless you look at the documentation in parallel). That’s because the website itself is clunky and not very easy to navigate. On the other hand, the console allows you to configure your pipeline down to the smallest details, so it’s hard to wrap up all the existing features in an easy to use package. The reporting available is good, but there’s always room for improvement. Analytics on message origin would be beneficial."

W: “The dashboard UI is easy to understand and self-explanatory. On the downside there is no informative metrics available but on the upside there is a lot of functionality and configurations options and the API console where you can send HTTP and GraphQL queries is a nice feature.”

Realtime features

Pub/Sub messaging

Pub/Sub is a design pattern that lets any number of publishers (producers) push messages to channels (also known as topics). Multiple subscribers (consumers) can subscribe to a channel to consume published messages.

Explore Ably's pub/sub messaging implementation

Limited

There is support for pub/sub messaging using LiveQueries in the Javascript SDK, which uses WebSockets to subscribe & publish to channels. But LiveQueries is limited to the Javascript SDK.

Message queues

A message queue is a form of asynchronous service-to-service communication. Messages are stored on a queue until they are processed. Note that each message is only consumed by one subscriber (consumer).

Explore Ably's message queues implementation

Limited

Amazon SNS integrates with Amazon SQS (Simple Queue Service) in order to offer traditional message queue functionality. However, Amazon SNS does not provide message queues by itself.

Presence

Presence enables you to track the online and offline status of devices and end-users in real time and to store their state. Essential for chat apps and multiplayer games.

Explore Ably's presence implementation

Limited

One could keep track of online clients by using the LiveQuery triggers to know whether or not a client is connected. But there is no built functionality for this.

Message history

Message history provides a means to retrieve previously published messages. For this to be possible, message data must be stored (persisted) somewhere.

Explore Ably's message history implementation

Connection state recovery (stream resume)

In the case of unreliable network conditions, clients may suddenly disconnect.Connection state recovery ensures that when they reconnect, the data stream resumes exactly where it left off.

Explore Ably' s connection state recovery implementation

N/A

Guaranteed message ordering

Ordering ensures that messages are delivered to consumers in the same order that producers publish them.

Explore Ably' s guaranteed message ordering implementation

Limited

Amazon SNS guarantees message ordering via FIFO topics. However, ordering is only guaranteed when sending messages to Amazon SQS FIFO queues.

Exactly-once semantics

Exactly-once is a system-wide data integrity guarantee that ensures each message is delivered to consumers exactly-once.

Explore Ably' s idempotent publishing implementation

Limited

Amazon SNS guarantees exactly-once semantics via FIFO topics. However, it only supports exactly-once when sending messages to Amazon SQS FIFO queues.

Limited 

Idempodency enforcement exists, as an experimental feature that may not be appropriate for production.

Message delta compression

Message delta compression enables you to only send the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Useful for use cases where there is a significant degree of similarity between successive messages.

Explore Ably' s message delta compression implementation

Native push notifications

Native push notifications can be used to deliver messages even when clients are offline. Useful for geolocation updates or news alerts.

Explore Ably's push notifications implementation

Webhooks

Webhooks provide a mechanism to get messages and other types of events (such as clients entering or leaving channels) pushed to your servers over HTTP.

Explore Ably's webhooks implementation

Serverless functions

A serverless function is essentially an isolated, single-purpose piece of code that is only executed when it’ triggered by an event. For example, you can use serverless functions to send a welcome message to clients when they become present on chat channels.

Note that serverless functions are usually fully managed by cloud vendors.

Explore Ably's serverless functions implementation

Limited

Can only invoke AWS Lambda Functions. Amazon SNS does not support other serverless platforms, such as Azure Functions or Google Cloud Functions.

Limited

Cloud functions are used in parse server to run single-prupose piece of code. But is up to you to host the parse server, where the cloud functions are invoked from. The pricing model is different, since you are hosting the parse server yourself, you can invoke the cloud function for as many times as you like. Services like AWS Lambda charges you for the number of requests made and the duration of those requests.

Pricing model

How are the Amazon SNS and Parse server pricing models calculated?

Explore Ably's pricing model for our pub/sub messaging platform

Amazon SNS pricing is usage-based.

Standard topics

Once you deplete the free tier usage, the pricing is:

- $0.50 per million Amazon SNS requests 

- $0.50 per million mobile push notifications

- $2 per 100.000 email/JSON notifications

- $0.60 per million HTTP/s notifications

FIFO topics

Pricing is calculated based on the number of published messages, the number of subscribed messages, and payload data:

- publish requests are $0.30 per 1 million and $0.017 per GB of payload data

- subscription messages are $0.01 per 1 million and $0.001 per GB of payload data

Data transfer out of Amazon SNS is also charged. Pricing varies depending on the volume of data. For example, the first 1 GB per month is free, while the next 9.999 TB costs $0.09 per GB.

If you look at the AWS SNS forum, you can see that some of the threads have even 20.000 or 30.000 views. Unfortunately, there seem to be a lot of questions without an answer.
