How is 'Kubernetes' correctly pronounced?
Kubernetes = /ˌkjuːbərˈnetɪz/ — "kyoo-ber-NET-iz." Four syllables: kyoo-ber-NET-iz. Stress on the third syllable: kyoo-ber-NET-iz. The name comes from the Greek word for "helmsman" or "pilot" (κυβερνήτης). The /kj/ onset sounds like the "cu" in "cute." The second syllable /bər/ is reduced (schwa). The third syllable /ˈnet/ gets the main stress. The final syllable /ɪz/ is short. "kyoo-ber-NEE-tiz" (with a long EE) is a very common mistake — the vowel in "NET" is short /ɛ/, not long /iː/. In conversation, it's frequently shortened to just "k8s" (written) or "kates" or "kube" (spoken).

How do DevOps engineers pronounce 'nginx'?
nginx = /ˈɛnˌdʒɪnˈɛks/ — "en-JIN-ex." Three syllables: en-JIN-ex. The creator Igor Sysoev pronounces it this way, and the official nginx documentation confirms it. Breaking it down: "n" + "gine" (as in "engine") + "x." So: engine → en-jin → add the "x" → en-JIN-ex. A common mistake is trying to pronounce it as a single word: "nig-inx" or "NJINX" — these are not standard. Another common variant is "EN-jinx" (with the X as "ks") — but the standard is "en-JIN-ex" with X as just "ex." When typing, lowercase "nginx" is the convention.

How do database engineers pronounce 'PostgreSQL'?
PostgreSQL = /ˈpoʊstɡrɛs ˌsiːkwəl/ — "POST-gres SEE-kwel." The official PostgreSQL documentation says: pronounce it "POST-Gres-Q-L" or "POST-gres sequel." In practice, most database engineers say "POST-gres" and then "sequel" — the same way MySQL and SQL Server are spoken. "Post" + "Gres" = two syllables for the first part (POST-gres). Then "sequel" /ˌsiːkwəl/. The full name is sometimes shortened to just "Postgres" in speech: "We're using Postgres" — perfectly acceptable. Avoid "post-gray-si-kul" which misreads the spelling entirely.

How is 'Redis' pronounced by its creator and the Redis community?
Redis = /ˈrɛdɪs/ — "RED-is." Two syllables: RED-is. The name stands for "Remote Dictionary Server." The first syllable /rɛd/ is identical to the colour "red" — same short /ɛ/ vowel. The second syllable /ɪs/ is unstressed. The creator Salvatore Sanfilippo (antirez) has confirmed the "RED-is" pronunciation. "REE-dis" with a long EE is a very common mistake — people assume a long vowel because of the "Re-" prefix pattern in words like "React" and "Redux." But Redis has the short /ɛ/ vowel from its full name "Remote." In conversation: "We cache it in Redis" — sounds like "We cache it in red-is."

How do data engineers pronounce 'Kafka' (Apache Kafka)?
Kafka = /ˈkæfkə/ — "KAF-kuh." Two syllables: KAF-kuh. The name comes from Franz Kafka, the author, and the surname pronunciation in most English-language contexts uses the short /æ/ vowel (as in "cat") for the first syllable. Stress is on the first syllable. The second syllable is a schwa: /kə/. Note: in Czech/German (closer to the original), it might be /ˈkafka/ with a more open A — but in English tech circles, "KAF-kuh" (/ˈkæfkə/) is standard. "KAYF-kuh" (/ˈkeɪfkə/) with a diphthong is a common mistake — avoid making the A into a long vowel sound.
