Ilya Afanasyev - PeerSpot reviewer
A great solution with an intricate system and allows for batch data processing
We value this solution's intricate system because it comes with a state inside the mechanism and product. The system allows us to process batch data, stream to real-time and build pipelines. Additionally, we do not need to process data from the beginning when we pause, and we can continue from the same point where we stopped. It helps us save time as 95% of our pipelines will now be on Amazon, and we'll save money by saving time.

Native connectors and integration simplify tasks but portfolio complexity needs addressing
There are too many products in the Azure landscape, which sometimes leads to overlap between them. Microsoft continuously releases new products or solutions, which can be frustrating when determining the appropriate features from one solution over another. A cost comparison between products is also not straightforward. They should simplify their portfolio. The Microsoft licensing system is confusing and not easy to understand, and this is something they should address. In the future, I may stop using Stream Analytics and move to other solutions. I discussed Palantir earlier, which is something I want to explore in depth because it allows me to accomplish more efficiently compared to solely using Azure. Additionally, the vendors should make the solution more user-friendly, incorporating low-code and no-code features. This is something I wish to explore further.

Quotes from Members

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

Pros

"With Flink, it provides out-of-the-box checkpointing and state management. It helps us in that way. When Storm used to restart, sometimes we would lose messages. With Flink, it provides guaranteed message processing, which helped us. It also helped us with maintenance or restarts."
"Allows us to process batch data, stream to real-time and build pipelines."
"Apache Flink allows you to reduce latency and process data in real-time, making it ideal for such scenarios."
"The top feature of Apache Flink is its low latency for fast, real-time data. Another great feature is the real-time indicators and alerts which make a big difference when it comes to data processing and analysis."
"Apache Flink's best feature is its data streaming tool."
"Another feature is how Flink handles its radiuses. It has something called the checkpointing concept. You're dealing with billions and billions of requests, so your system is going to fail in large storage systems. Flink handles this by using the concept of checkpointing and savepointing, where they write the aggregated state into some separate storage. So in case of failure, you can basically recall from that state and come back."
"The documentation is very good."
"The product helps us to create both simple and complex data processing tasks. Over time, it has facilitated integration and navigation across multiple data sources tailored to each client's needs. We use Apache Flink to control our clients' installations."
"The most valuable aspect is the SQL option that Azure Stream Analytics provides."
"The most valuable features of Azure Stream Analytics are the ease of provisioning and the interface is not terribly complex."
"I like the way the UI looks, and the real-time analytics service is aligned to this. That can be helpful if I have to use this on a production service."
"It provides the capability to streamline multiple output components."
"The life cycle, report management and crash management features are great."
"I like all the connected ecosystems of Microsoft, it is really good with other BI tools that are easy to connect."
"Any time I needed assistance, they were helpful."
"It's scalable as a cloud product."
 

Cons

"The state maintains checkpoints and they use RocksDB or S3. They are good but sometimes the performance is affected when you use RocksDB for checkpointing."
"In terms of stability with Flink, it is something that you have to deal with every time. Stability is the number one problem that we have seen with Flink, and it really depends on the kind of problem that you're trying to solve."
"PyFlink is not as fully featured as Python itself, so there are some limitations to what you can do with it."
"There is room for improvement in the initial setup process."
"Amazon's CloudFormation templates don't allow for direct deployment in the private subnet."
"In a future release, they could improve on making the error descriptions more clear."
"There are more libraries that are missing and also maybe more capabilities for machine learning."
"There is a learning curve. It takes time to learn."
"There are too many products in the Azure landscape, which sometimes leads to overlap between them."
"I would like to have a contact individual at Microsoft."
"There is a lack of technical support from Microsoft's local office, particularly in Taiwan."
"If something goes wrong, it's very hard to investigate what caused it and why."
"The solution could be improved by providing better graphics and including support for UI and UX testing."
"There are too many products in the Azure landscape, which sometimes leads to overlap between them."
"The solution's interface could be simpler to understand for non-technical people."
"It is not complex, but it requires some development skills. When the data is sent from Azure Stream Analytics to Power BI, I don't have the access to modify the data. I can't customize or edit the data or do some queries. All queries need to be done in the Azure Stream Analytics."
 

Pricing and Cost Advice

"It's an open-source solution."
"This is an open-source platform that can be used free of charge."
"The solution is open-source, which is free."
"It's an open source."
"Apache Flink is open source so we pay no licensing for the use of the software."
"We pay approximately $500,000 a year. It's approximately $10,000 a year per license."
"I rate the price of Azure Stream Analytics a four out of five."
"The current price is substantial."
"The licensing for this product is payable on a 'pay as you go' basis. This means that the cost is only based on data volume, and the frequency that the solution is used."
"The cost of this solution is less than competitors such as Amazon or Google Cloud."
"The product's price is at par with the other solutions provided by the other cloud service providers in the market."
"There are different tiers based on retention policies. There are four tiers. The pricing varies based on steaming units and tiers. The standard pricing is $10/hour."
"When scaling up, the pricing for Azure Stream Analytics can get relatively high. Considering its capabilities compared to other solutions, I would rate it a seven out of ten for cost. However, we've found ways to optimize costs using tools like Databricks for specific tasks."
