The best service available with easy message flow and a pay-as-you-go model

Messages easily flow from publisher or application to subscriber. You can also flow messages from publisher to SNS with an https-like mediator. Amazon SQS is there, so message queue services are also there. The message transports to the service provider such as Redshift, the SQ bucket, Teams, Splunk, or any other message service. The solution has no up-front costs. Messages flow much more quickly than in the past. They used to run a bit late after being published.

Offers a seamless way to decouple applications, providing impressive performance and flexibility

Regarding improving the PubSub+ Platform, I'm not sure about the pricing aspect, but I heard that it is quite expensive compared to Kafka. That's the only concern I can mention; otherwise, it was as impressive as Kafka, better than Kafka based on my experience working on the Solace and Kafka white paper.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It's a simple communication service that allows us to communicate with customers."

"The most valuable feature of Amazon SNS is speed. It's really fast."

"Stability has been good for us. It is quite high."

"Messages easily flow from publisher or application to subscriber."

"The integration between the features is excellent."

"Push notifications are the most valuable. I have mostly used push notifications for my system. Amazon SNS supports all devices for push notification services. It supports iOS, Android, and Windows notifications. It provides reliable push notification services. We have queues, and we can track which notifications have failed or had some issues. We can then figure out the issue. We can also debug the issue because of which our push notification didn't reach the end users."

"The mobile push notifications are the most valuable. Previously, we used to use Firebase Cloud Messaging (FCM) for this functionality. It is a Google service for sending push notifications. Android did not have a good service for sending push notifications, but now, Amazon SNS integrates with FCM. Under the road, it is actually using FCM, but we can see all the metrics on our AW service itself, which makes it a lot easier instead of using a third-party service for this particular functionality."

"The best aspect of this solution is its simplicity. We just have to create topics and can have as many subscriptions as we want under any topic we create."

More Amazon SNS pros

"This solution reduces the latency to access changes in real-time and the effort required to onboard a new subscriber. It also reduces the maintenance of each of those interfaces because now the publisher and subscribers are decoupled. Event Broker handles all the communication and engagement. We can just push one update, then we don't have to know who is consuming it and what's happening to that publication downstream. It's all done by the broker, which is a huge benefit of using Event Broker."

"One of the main reasons for using PubSub+ is that it is a proper event manager that can handle events in a reactive way."

"The best features of PubSub+ Platform include being highly scalable, allowing us to handle billions and billions of events, and configuring and managing PubSub+ Platform is straightforward and simple while being highly reliable."

"In my assessment of Solace against other products — as I was responsible for evaluating various products and bringing the right tool into companies in the past — I worked with multiple platforms like RabbitMQ, Confluent, Kafka, and various other tools in the market. But I found the event mesh capability to be a very interesting as well as fulfilling capability, towards what we want to achieve from a digital-integration-strategy point of view... It's distributed, yet it is intelligently connected. It can also span and I can plug and play any number of brokers into the event mesh, so it's a great deal. That's a differentiator."

"The valuable feature of PubSub+ Event Broker is the speed of processing, publishing, and consumption."

"When it comes to granularity, you can literally do anything regarding how the filtering works."

"We've built a lot of products into it and it's been quite easy to feed market data onto the systems and put entitlements and controls around that. That was a big win for us when we were consolidating our platforms down. Trying to have one event bus, one messaging bus, for the whole globe, and consolidate everything over time, has been key for us. We've been able to do that through one API, even if it's across the different languages."

"The event portal and the diversity of deployment options in a hybrid landscape are the most valuable features."

Cons

"A major issue with AWS as a whole is that it has a lot of services that do the same thing, and people get confused about which one to use in which scenario. Previously, we used to use SNS for connecting microservices. SNS has around six types of subscribers. We can subscribe to Lambda, HTTP, HTTPS, SMS, email, and push notifications. We used to use HTTP endpoints and Lambda for connecting to microservice systems. Now we have something called EventBridge, which actually does that for you. For connecting to services, we should just use EventBridge rather than SQS, SNS. I hear a lot of complaints from people wherein they do not understand when to use EventBridge and when to use SQS, SNS. They can remove these features so that it doesn't confuse users about when to use SQS, SNS, or EventBridge."

"We would like to have the option when someone leaves the organization or moves to another team, to remove notifications. Currently this needs to be done manually by the company admin."

"We would like the integration with third party applications to be improved within this solution."

"The tool needs to have direct integration with AvPro."

"In future releases, I want to see if the platforms that SMS can reach. It would be a good way to improve it. More platforms to be able to use it."

"I expect Amazon SNS to provide some capabilities to allow the configuration process to be done in a single script."

"There needs to be more documentation on the integration with different platforms."

"I recently worked with Firebase, and it provides an option to create a marketing campaign with a title and a specific image to inform our audience about something. We just design the campaign and then use the push notifications. It would be good if Amazon also adds a similar feature."

More Amazon SNS cons

"For improvements, I would suggest increasing the max payload size to a limit of 100MB or more. The current max payload size is limited to 5MB."

"The ease of management could be approved. The GUI is very good, but to configure and manage these devices programmatically in the software version is not easy. For example, if I would like to spin up a new software broker, then I could in theory use the API, but it would require a considerable amount of development effort to do so. There should be a tool, or something that Solace supports, that we could use for this, e.g., a platform like Terraform where we could use infrastructure as code to configure our source appliances."

"The integrations could improve in PubSub+ Event Broker."

"We have requested to be able to get into the payload to do dynamic topic hierarchy building. A current workaround is using the message's header, where the business data can be put into this header and be used for a dynamic topic lookup. I want to see this in action when there are a couple of hundred cases live. E.g., how does it perform? From an administration perspective, is the ease of use there?"

"Some of the feature's gaps with some of the open-source vendors have been closed in a lot of ways. Being more agile and addressing those earlier could be an area for improvement."

"It could be cheaper. It could also have easier usage. It is a brilliant product, but it is quite complex to use."

"If you create one event in the past, you cannot resend it."

"I heard that it is quite expensive compared to Kafka."

Pricing and Cost Advice

"One can use the tool for free."

"The pricing of push notifications and everything is quite fair. If you are using FCM under the hood, it is completely free. When you are using push notification on SMS, it is just a nominal price that you need to pay. SMS services are a lot more costly. It is because we don't have proper providers in India. That's why it gets a lot more costly in terms of SMS. This is the reason why we don't use SMS services from SNS itself. We use other third-party services like SMS Horizon. We use a third-party service for email services. It is almost free. It is just around $1 a month. Configuring Lambda is also quite cheap. You only pay for the Lambda usage. You don't pay for SNS itself."

"The pricing is very cheap."

"Their pricing is competitive. I would rate the cost four out of five."

"The solution has no up-front costs because you pay based on the number of messages you publish."

"It is the cheapest solution in the market. It is on a monthly basis. After a month, you are build based on your usage. There are no additional costs to the standard licensing fees."

"Amazon SNS is cheap and I would rate it a three out of ten. The pricing is usage-based."

"Having a free version is critical for our technology operations use case. This is primarily because our technology operations team is a cost center in our company. They are not profit drivers and having a free version for installation will probably meet our needs. Even for production, it'll support up to a 100,000 messages per second. I don't think in technology operations that we have that many events and alerts from our detection tools. Even if I have 20 or 30 event detection products out there, they're only going to publish the things which are critical or warnings. I don't think we'll ever reach a 100,000 messages per second."

"The price of the solution is expensive."

"We are looking for something that will add value and fit for purpose. Freeware is good if you want to try something quickly without putting in much money. However, as far as our decision is concerned, I don't think it helps. At the end of the day, if we are convinced that a capability is required, we will ask for the funding. Then, when the funding is available, we will go for an enterprise solution only."

"We have been really happy with the product licensing rates. It has been free for us, up to a 100,000 transactions per second, and all we have to do is pay for support. Making their product available and accessible to us has not been a problem at all."

"There are different tiers where you can choose what would work for you. As a customer, you need to know roughly how many messages a month you will use."

"The licensing is dependent on the volume that is flowing. If you go for their support services, it will cost some more money, but I think it is worth it, especially if you are just starting your journey."

"It could be cheaper. Its licensing is on a yearly basis."

"Having a free version of the solution was a big, important part of our decision to go with it. This was the big driver for us to evaluate Solace. We started using it as the free version. When we felt comfortable with the free version, that is when we bought the enterprise version."

Overview

Amazon Simple Notification Service (SNS) is a highly available, durable, secure, fully managed pub/sub messaging service that enables you to decouple microservices, distributed systems, and serverless applications. Amazon SNS provides topics for high-throughput, push-based, many-to-many messaging. Using Amazon SNS topics, your publisher systems can fan out messages to a large number of subscriber endpoints for parallel processing, including Amazon SQS queues, AWS Lambda functions, and HTTP/S webhooks. Additionally, SNS can be used to fan out notifications to end users using mobile push, SMS, and email.

You can get started with Amazon SNS in minutes by using the AWS Management Console, AWS Command Line Interface (CLI), or AWS Software Development Kit (SDK).
