Comparing DMS for Kafka and Open-Source Kafka¶
DMS is compatible with open-source Kafka and has customized and enhanced Kafka features. In addition to the advantages of open-source Kafka, DMS for Kafka provides more reliable and useful features.
Category | Item | DMS | Open-source Kafka |
|---|---|---|---|
Ease of use | Readily available | Instances can be created intuitively within minutes and used right out of the box with visualized operations and real-time monitoring. | Preparing server resources and installing and configuring the software is time-consuming and prone to mistakes. |
APIs | Instances can be managed easily by calling RESTful APIs. | N/A | |
Costs | On-demand use | Multiple specifications are available to suit different needs. The instance broker quantity, broker flavor, and disk space can be increased with a few clicks. | Expenses are incurred for setting up a message service and occupying underlying resources. |
Fully managed | Services are readily available without requiring additional hardware resources or expenses. | Users must prepare hardware resources and set up the service by themselves, and bear high usage and maintenance costs. | |
Proven success | Mature | DMS has been deployed in many cloud products and proven successful in large e-commerce events. It is also used in the clouds of carrier-grade customers across the world, and meets strict carrier-grade reliability standards. DMS closely follows up with community updates to continuously fix known open-source vulnerabilities and add support for new features. | Using open-source software requires lengthy self-development and verification and has had few successful cases. |
Feature-rich | While maintaining 100% open-source compatibility, DMS further optimizes open-source code to improve performance and reliability, and provides message querying, and many other features. | Functionality is limited and requires self-development. | |
Reliability | Highly available | DMS supports cross-AZ deployment to improve reliability. In addition, automatic fault detection and alarms ensure reliable operations of key services. | High availability requires self-development or open-source code implementation, which are costly and cannot guarantee reliability. |
Simple O&M | O&M is entirely transparent to tenants with a full set of monitoring and alarm functions. O&M personnel will be informed of any exceptions, eliminating the need for 24/7 attending. | Users need to develop and optimize O&M functions, especially alarm notification functions. Otherwise, manual attendance is required. | |
Secure | DMS uses VPC isolation, disk encryption, and SSL channel encryption. | Security must be hardened by users themselves. |
