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.

Performs well, high availability, and helpful support

We use approximately four people for the maintenance of the solution. My advice to others is this solution has high throughput and is used for many stock exchanges. For business critical use cases, such as processing financial transactions at a quick speed, I would recommend this solution. I rate PubSub+ Event Broker an eight out of ten.

Quotes from Members

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

Pros

"We have found the key feature of this solution to be the simplicity of sending out notifications."

"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."

"Amazon SNS has SMS notifications as well. Most of the other solutions have only email notifications."

"The initial setup of Amazon SNS was easy."

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

"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."

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

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

More Amazon SNS pros

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

"Guaranteed Messaging allows for us to transport messages between on-prem and the cloud without any loss of data."

"Some valuable features include reconnecting topics, placing queues, and direct connections to MongoDB. The platform provides a dashboard to monitor the status of messages, such as how many have been processed or delivered, which is helpful for tracking performance."

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

"When we went to add another installation in our private cloud, it was easy. We received support from Solace and the install was seamless with no issues."

"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 topic hierarchy is pretty flexible. Once you have the subject defined just about anybody who knows Java can come onboard. The APIs are all there."

"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."

More PubSub+ Platform pros

Cons

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

"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."

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

"Messages should flow through a gateway without the need for a mediator."

"In terms of improvement, I would like to have better customer support for SNS. We can then manage it very easily."

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

"There could be more integration with other solutions."

"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."

More Amazon SNS cons

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

"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."

"The product should allow third-party agents to be installed. Currently, it is quite proprietary."

"We've pointed out some things with the DMR piece, the event mesh, in edge cases where we could see a problem. Something like 99 percent of users wouldn't ever see this problem, but it has to do with if you get multiple bad clients sending data over a WAN, for example. That could then impact other clients."

"The section on observability pertains to understanding the functioning of an event crash. Instead of focusing on how the crash occurs, attention is given to the observable aspects, such as a memory pipeline where one person pushes messages and another reads them. However, this pipeline often encounters issues, such as the reader being unavailable, causing the system to become stuck and preventing the messages from moving forward. This can lead to the pipeline being permanently stalled."

"One of the areas of improvement would be if we could tell the story a bit better about what an event mesh does or why an event mesh is foundational to a large enterprise that has a wide diversity of applications that are homegrown and a small number off the shelf."

"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."

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

Pricing and Cost Advice

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

"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."

"The pricing is very cheap."

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

"One can use the tool for free."

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

"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."

"I would rate the product's pricing a ten out of ten."

"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."

"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."

"The price of PubSub+ Event Broker is reasonable for the capability it offers. However, when compared to others solutions on the market it is expensive."

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

"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."

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).
