Apache Kafka vs. Apache Pulsar vs. SAP NetWeaver Application Server

Apache Kafka is well-suited for most data-streaming use cases. Amazon Kinesis and Azure EventHubs, unless you have a specific use case where using those cloud PaAS for your data lakes, once set up well, Apache Kafka will take care of everything else in the background. Azure EventHubs, is good for cross-cloud use cases, and Amazon Kinesis - I have no real-world experience. But I believe it is the same.

SAP NetWeaver is well suited for contract file storage and management. SAP NetWeaver is less appropriate for entering in time and attendance.

• Really easy to configure. I've used other message brokers such as RabbitMQ and compared to them, Kafka's configurations are very easy to understand and tweak.
• Very scalable: easily configured to run on multiple nodes allowing for ease of parallelism (assuming your queues/topics don't have to be consumed in the exact same order the messages were delivered)
• Not exactly a feature, but I trust Kafka will be around for at least another decade because active development has continued to be strong and there's a lot of financial backing from Confluent and LinkedIn, and probably many other companies who are using it (which, anecdotally, is many).

• Control of inventory
• Organization of my clients
• Complete reports
• Autorization by level

• Sometimes it becomes difficult to monitor our Kafka deployments. We've been able to overcome it largely using AWS MSK, a managed service for Apache Kafka, but a separate monitoring dashboard would have been great.
• Simplify the process for local deployment of Kafka and provide a user interface to get visibility into the different topics and the messages being processed.
• Learning curve around creation of broker and topics could be simplified

• sometimes in linux OS we face several issues during start and stop. Sometimes Zombie process still exists after clean shutdown that time we need to manually kill those processes otherwise it might not start properly. Here SAP can improve.

Kafka is quickly becoming core product of the organization, indeed it is replacing older messaging systems. No better alternatives found yet

Apache Kafka is highly recommended to develop loosely coupled, real-time processing applications. Also, Apache Kafka provides property based configuration. Producer, Consumer and broker contain their own separate property file

Support for Apache Kafka (if willing to pay) is available from Confluent that includes the same time that created Kafka at Linkedin so they know this software in and out. Moreover, Apache Kafka is well known and best practices documents and deployment scenarios are easily available for download. For example, from eBay, Linkedin, Uber, and NYTimes.

I did not give SAP NetWeaver a 10, only because getting access to it initially can be tricky and sometimes it's very slow to load up.

Incentivized

I used other messaging/queue solutions that are a lot more basic than Confluent Kafka, as well as another solution that is no longer in the market called Xively, which was bought and "buried" by Google. In comparison, these solutions offer way fewer functionalities and respond to other needs.

Most of the other applications only provide one business module to use, whereas SAP Netweaver Application server can cover all business areas. It provides both ABAP & Java features, meaning it can host Portal applications and be also used for having online transactions. The application codes are easily modifiable & can be made to fit user needs. This application is suited for all type of business demands

Incentivized

• Positive: Get a quick and reliable pub/sub model implemented - data across components flows easily.
• Positive: it's scalable so we can develop small and scale for real-world scenarios
• Negative: it's easy to get into a confusing situation if you are not experienced yet or something strange has happened (rare, but it does). Troubleshooting such situations can take time and effort.

Incentivized

• Great ROI. We need to invest in new developments, making it more functional for our business.
• We have requests that couldn't be duplicated. Maybe we need to pay to fix that.
• We have a lot of transactions and don't have anyone that can guide us to the ones that we need to improve our business.
