Deskripsi:

In this open lesson, Alexander Krylov explains load balancing algorithms in HAProxy. The session begins at 00:00 with an introduction, followed by an overview at 00:58. At 03:49 he defines load balancing, then at 05:52 he discusses the separation of front‑end and back‑end. The next sections cover front‑end at 06:29, back‑end at 08:34, and HAProxy configuration for both at 14:53. At 18:23 he shows how the configuration appears in practice and in statistics, and at 24:22 he answers questions. The lesson continues with TCP/UDP balancing at 41:49, a brief mention of the DevOps practice at 50:30, and further Q&A at 55:30. The speaker then covers types of balancing at 01:00:49, followed by more Q&A at 01:05:27. He explains the round‑robin method at 01:16:50, discusses round‑robin in HAProxy at 01:18:10, and covers least connections at 01:18:53. At 01:23:13 he explains leastconn in HAProxy, gives an example at 01:24:37, discusses least response time at 01:29:41, hash at 01:32:33, source at 01:35:26, and custom load at 01:43:30, concluding with a summary at 01:45:23.
