Distributed Message Queuing Service (Kafka) provides more functions and services comparing to open-source Kafka, and has the following advantages:

Comparison Items	Open-Source and Self-Built	Distributed Message Service (Kafka)
Low-cost O&M	Experts are required for resource planning, deployment, and O&M.	One click to activate, fully managed. Provide a variety of specifications for on-demand use, and support one-click expansion on the node number, disk storage space, and node specifications.
Partition Size	The stability decreases when partitions exceed 1,000.	Provide a cloud-native Kafka engine that supports stable writing even if the partition number exceeds 10,000.
Query Message	You can consume messages by running commands on the CLI. However, you cannot query messages by offset or time.	The console visualizes the direct view of messages by time or offset.
ACL Access Control	Command line with complex configurations.	Flexible configurations with one click to apply.
Visual Configurations	Command line with complex configurations.	The console provides all-round visual configuration management.
O&M Monitoring	Lack of corresponding monitoring and O&M capabilities.	Provides visual monitoring of all engine metrics to identify problems and send alarms promptly.
Cluster Inspection	Command line with complex configurations.	Perform health checks on the engine and topics. Support one-click start and stop.
High Stability and Reliability	You must further develop it, which can involve high costs, or just use the open-source version, which cannot guarantee your business reliability.	Support cross-AZ deployment to improve reliability.
Security	Require security reinforcement by yourself.	Support VPC isolation and SSL channel encryption.
Simple and easy to use.	No, you need to develop it yourself.	Instances can be managed easily by calling RESTFul APIs, easy and simple.
