Unified user personas have improved data workflows and support detailed monitoring and logging

Google Cloud has many streams and products. In Google Cloud, everything is translated in the backend, so we do not have to use services such as Apache Beam. When you want to use Google Cloud Functions, you write the code, and the backend talks to all the libraries or Apache, so we do not need to be concerned about those. We just need to use our functions that translate and have many tools and services readily available. Google Cloud Dataflow has made it very easy for detailed monitoring and logging features for pipeline performance assessment. For example, if I am using Google Cloud Functions, I can easily see what changes I have done and trace it properly. I can see what is happening with this script, how many users are affected, whether the script is working, what is failing, and how we can rectify issues with proper monitoring.

A solution for data pipelines but has connector limitations

We have used Kafka for seven years. IBM streams gives you many OOTB features that can boost the time-to-market, especially when it comes to reporting and monitoring for example. Confluent is recognized as one of the leaders in this space and the main reason for this is related to the complete vision of the platform also the large number of connectors. This gives the edge and competitive advatnage.

Quotes from Members

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

Pros

"Google Cloud Dataflow has made it very easy for detailed monitoring and logging features for pipeline performance assessment."

"The service is relatively cheap compared to other batch-processing engines."

"The best feature of Google Cloud Dataflow is its practical connectedness."

"The most valuable features of Google Cloud Dataflow are the integration, it's very simple if you have the complete stack, which we are using. It is overall very easy to use, user-friendly friendly, and cost-effective if you know how to use it. The solution is very flexible for programmers, if you know how to do scripts or program in Python or any other language, it's extremely easy to use."

"The integration within Google Cloud Platform is very good."

"I would rate the overall solution a ten out of ten."

"It allows me to test solutions locally using runners like Direct Runner without having to start a Dataflow job, which can be costly."

"The product's installation process is easy...The tool's maintenance part is somewhat easy."

More Google Cloud Dataflow pros

"As a result, the TELCO company was able to cut down the time it took to respond to customer needs and there were fewer complaints."

"The product has enabled us to create solutions to client problems that would have either been impossible or very expensive/difficult using other technologies."

"Easy development and deployment, Java implementation features, and the real time analyser and alarm function are the most valuable features for us."

"The OEM Solution (Excel-medical.com) running on top of IBM Streams provides real-time clinical algorithms that can give better insight into the patient's acuity, thus cutting off time to discharge patients and inversely making sure that sick patients don't get discharged until ready."

Cons

"The technical support has slight room for improvement."

"I would like Google Cloud Dataflow to be integrated with IT data flow and other related services to make it easier to use as it is a complex tool."

"Promoting the technology more broadly would help increase its adoption."

"When I deploy the product in local errors, a lot of errors pop up which are not always caught. The solution's error logging is bad. It can take a lot of time to debug the errors. It needs to have better logs."

"Currently, not all error logs are available to users and this could make debugging failed jobs very difficult."

"The authentication part of the product is an area of concern where improvements are required."

"The technical support is very hard to reach."

"The deployment time could also be reduced."

More Google Cloud Dataflow cons

"I’d like to see a tool kit specifically targeted at incremental machine learning. It’s already great for scoring previously trained models, but dynamically updating models is currently more of a 'grow your own' kind of thing."

"We had some stability issues where we used embedded Zookeeper in production."

"The price and versatility of this product need to improve - it is not inexpensive."

"The development IDE sometimes crashes and freezes."

Pricing and Cost Advice

"The price of the solution depends on many factors, such as how they pay for tools in the company and its size."

"Google Cloud Dataflow is a cheap solution."

"The solution is cost-effective."

"The solution is not very expensive."

"Google Cloud is slightly cheaper than AWS."

"The tool is cheap."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven to eight out of ten."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate Google Cloud Dataflow's pricing a four out of ten."
