Fluentd & Fluent Bit
The Production Grade Ecosystem
Logging and data processing in general can be complex, and substantially more so at scale. That's why Fluentd was born. Now, Fluentd is more than a simple tool. It's a full ecosystem that contains SDKs for different languages and sub projects like Fluent Bit.
On this page, we will describe the relationship between the Fluentd and Fluent Bit open source projects. As a summary, we can say both are:
- Licensed under the terms of Apache License v2.0
- Production Grade solutions: deployed thousands of times every single day, millions per month.
- Community driven projects
- Widely Adopted by the Industry: trusted by all major companies like AWS, Microsoft, Google Cloud and hundred of others.
Both projects have a lot of similarities. Fluent Bit is fully designed and built on top of the best ideas of the Fluentd architecture and general design. Choosing which one to use depends on the end-user needs.
The following table describes a comparison in different areas of the projects:
