How is 'RabbitMQ' pronounced?
RabbitMQ is pronounced /ˈræbɪt ɛm kjuː/ — 'RAB-it EM KYOO'. It is a compound of 'Rabbit' plus the acronym 'MQ' (Message Queue). 'Rabbit' is a common English word: /ˈræbɪt/, with a short /æ/ vowel as in 'cat'. 'MQ' is always spelled out as two letter names: M = /ɛm/, Q = /kjuː/. The Q letter name in English is 'kyoo' /kjuː/ — not 'kew' or 'cue' (though 'cue' sounds similar). The full pronunciation flows as: RAB-it EM KYOO.

How is 'ActiveMQ' pronounced?
ActiveMQ is pronounced /ˈæktɪv ɛm kjuː/ — 'AK-tiv EM KYOO'. The 'Active' part follows standard English: /ˈæktɪv/, with short /æ/ as in 'act' and short /ɪ/ in the second syllable. A common mistake is using a long /aɪ/ vowel — 'AK-tyve' — which is wrong; it is 'AK-tiv'. 'MQ' is spelled out as 'EM KYOO'. Stress falls on the first syllable of 'Active': AK-tiv EM KYOO. It is an Apache project and widely used as the standard Java message broker.

How is 'NATS' pronounced?
NATS (Neural Autonomic Transport System, originally) is pronounced /næts/ — 'NATS', rhyming with 'bats', 'cats', and 'hats'. Unlike many IT acronyms, NATS is treated as a word, not spelled out letter by letter. The vowel is a short /æ/ as in 'back'. The final /s/ is unvoiced. In the NATS community and documentation, it is consistently said as a single syllable: 'NATS'. This makes it easy to remember: NATS is the sound the letters make when you read them together. It's a lightweight, high-performance cloud-native messaging system from CNCF.

How is 'Pulsar' pronounced?
Pulsar is pronounced /ˈpʌlsər/ — 'PUL-sur'. It shares its name with the astronomical object (a rotating neutron star emitting pulses of radiation), reflecting the tool's high-throughput, pulsing message delivery. The first syllable 'Pul' uses a short /ʌ/ vowel as in 'cup' or 'bus'. The second syllable '-sar' is reduced to /sər/ in American English (a rhotic schwa), not the full /sɑːr/ of the astronomical term. Stress falls on the first syllable: PUL-sur. Apache Pulsar is a direct competitor to Apache Kafka.

How is 'SQS' pronounced?
SQS (Amazon Simple Queue Service) is pronounced /ɛs kjuː ɛs/ — 'ESS KYOO ESS'. Each letter is spelled out individually: S = /ɛs/, Q = /kjuː/, S = /ɛs/. The letter 'Q' in English is named /kjuː/ — the same sound as the word 'queue'. SQS is Amazon's managed message queuing service, and in AWS contexts practitioners always spell it out as three letters. The doubled 'S' (ESS ... ESS) makes it clear where the service name begins and ends. Compare: SNS = 'ESS EN ESS', SES = 'ESS EE ESS'.
