Currently, we have approximately 9000 RabbitMQ clusters operating in 93 countries. According to the 2022 statistics, there was a 22 percent increase in clusters through 2023, and the growth seems to continue.
RabbitMQ version distribution
Approximately 30 percent of all customer’s servers are running RabbitMQ 3.12, released in 1 June 2023. An additional 18 percent are on 3.11 which, combined, is a great number as we like it when customers are on the newer versions.
However, a few users are still sticking with version 3.8 and 3.9, perhaps living by the motto “Don’t fix it if it ain’t broken!”
Language distribution by vhost
According to our statistics, .NET, Node.JS, and Python are the three most popular languages this year. Java closely follows in fourth place.
Client distribution by vhost
Top three client libs this year was Node.JS amqplib (18,9%), Java RabbitMQ (14,8%) and Python py-amqp (14,0%).
Median and largest numbers
Our servers are configured with two vhosts, three policies, and two users, a setup that most users seem to keep. However, we've observed some extreme cases, with one cluster having 142,516 bindings and another having 191,465 exchanges. If your setup approaches these numbers, it might be a signal to reevaluate your configuration. Feel free to reach out to us at support@cloudamqp.com for assistance.
The median number of bindings and queues is slightly higher than last year, but overall around the same numbers as 2022.
- Median number of queues: 26 (largest number of queues: 124400)
- Median number of users: 2 (largest number of users: 62,245)
- Median number of policies: 3 (largest numbers of policies: 2550)
- Median number of exchanges: 9 (largest number of exchanges: 191,465)
- Median number of bindings: 28 (largest number of bindings: 142,516)
- Median number of vhosts: 2 (largest number of vhosts: 1954)

Alarms configured
During 2023 we had 10,000 queue alarms setups, and 7000 disk alarms.
