\n\"Mikroslu\u017eby
\nV dob\u011b, kdy se IT sv\u011bt postupn\u011b p\u0159ech\u00e1z\u00ed na mikroslu\u017eby a n\u00e1stroje jako Kubernetes, se st\u00e1le v\u00edce vyplouv\u00e1 na povrch pouze jedna probl\u00e9ma. Tento probl\u00e9m je kombinatorn\u00ed exploze<\/a><\/noindex> verz\u00ed mikroslu\u017eeb. IT komunita v\u0161ak v\u011b\u0159\u00ed, \u017ee sou\u010dasn\u00e1 situace je v\u00fdrazn\u011b lep\u0161\u00ed ne\u017e \u201eDependency hell\u201c<\/a><\/noindex> minul\u00e1 generace technologi\u00ed. Nicm\u00e9n\u011b, spr\u00e1va verz\u00ed mikroslu\u017eeb je velmi slo\u017eit\u00fd probl\u00e9m. Jedn\u00edm z d\u016fkaz\u016f toho mohou b\u00fdt \u010dl\u00e1nky jako \u201eVr\u00e1t\u00edte mi m\u016fj monolit\u201c<\/a><\/noindex>.

\nPokud zat\u00edm nerozum\u00edte probl\u00e9mu, dovolte mi vysv\u011btlit. P\u0159edstavte si, \u017ee v\u00e1\u0161 produkt se skl\u00e1d\u00e1 z 10 mikroslu\u017eeb. Nyn\u00ed si p\u0159edstavte, \u017ee pro ka\u017edou z t\u011bchto mikroslu\u017eeb vych\u00e1z\u00ed 1 nov\u00e1 verze. Pouze 1 verze \u2013 douf\u00e1m, \u017ee se v\u0161ichni shodneme, \u017ee to je velmi trivi\u00e1ln\u00ed a nev\u00fdznamn\u00fd fakt. Nyn\u00ed se v\u0161ak pod\u00edvejme znovu na n\u00e1\u0161 produkt. Pouze se s jednou novou verz\u00ed ka\u017ed\u00e9 komponenty m\u00e1me nyn\u00ed 2^10 \u2013 nebo 1024 permutac\u00ed, jak lze n\u00e1\u0161 produkt sestavit.<\/p>\n

Pokud st\u00e1le z\u016fst\u00e1v\u00e1 nedorozum\u011bn\u00ed, dovolte mi rozlo\u017eit matematiku. Tak\u017ee m\u00e1me 10 mikroslu\u017eeb, z nich\u017e ka\u017ed\u00e1 dost\u00e1v\u00e1 jedno aktualizaci. To znamen\u00e1, \u017ee m\u00e1me 2 mo\u017en\u00e9 verze pro ka\u017edou mikroslu\u017ebu (bu\u010f starou, nebo novou). Nyn\u00ed, pro ka\u017ed\u00fd z komponent\u016f produktu m\u016f\u017eeme pou\u017e\u00edt jakoukoli z t\u011bchto dvou verz\u00ed. Matematicky je to tot\u00e9\u017e, jako bychom m\u011bli 10m\u00edstn\u00e9 bin\u00e1rn\u00ed \u010d\u00edslo. Nap\u0159\u00edklad, dejme tomu, \u017ee 1 je nov\u00e1 verze a 0 je star\u00e1 verze \u2013 pak jedna mo\u017en\u00e1 permutace m\u016f\u017ee b\u00fdt ozna\u010dena jako 1001000000 \u2013 kde prvn\u00ed a \u010dtvrt\u00fd komponent jsou aktualizov\u00e1ny, zat\u00edmco v\u0161echny ostatn\u00ed ne. Z matematiky v\u00edme, \u017ee 10m\u00edstn\u00e9 bin\u00e1rn\u00ed \u010d\u00edslo m\u016f\u017ee m\u00edt 2^10 nebo 1024 hodnot. To znamen\u00e1, \u017ee jsme potvrdili rozsah \u010d\u00edsla, se kter\u00fdm se vypo\u0159\u00e1d\u00e1v\u00e1me.<\/p>\n

Pokra\u010dujeme v \u00favah\u00e1ch d\u00e1le \u2014 co se stane, pokud budeme m\u00edt 100 mikroslu\u017eeb a ka\u017ed\u00e1 z nich bude m\u00edt 10 mo\u017en\u00fdch verz\u00ed? Cel\u00e1 situace se st\u00e1v\u00e1 velmi nep\u0159\u00edjemnou \u2014 nyn\u00ed m\u00e1me 10^100 permutac\u00ed \u2014 co\u017e je obrovsk\u00e9 \u010d\u00edslo. P\u0159esto bych tuto situaci ozna\u010dil pr\u00e1v\u011b tak, proto\u017ee se nyn\u00ed schov\u00e1v\u00e1me za slovy jako \u201ekubernetes\u201c a \u010del\u00edme probl\u00e9mu tak, jak je.<\/p>\n

Pro\u010d m\u011b tato probl\u00e9m tak fascinuje? Z\u010d\u00e1sti proto, \u017ee kdy\u017e jsem d\u0159\u00edve pracoval ve sv\u011bt\u011b NLP a AI, hodn\u011b jsme diskutovali o probl\u00e9mu kombinatorn\u00ed exploze asi p\u0159ed 5-6 lety. Jen m\u00edsto verz\u00ed jsme m\u011bli jednotliv\u00e1 slova a m\u00edsto produkt\u016f jsme m\u011bli v\u011bty a odstavce. A i kdy\u017e probl\u00e9my s NLP a AI z\u016fst\u00e1vaj\u00ed do zna\u010dn\u00e9 m\u00edry nevy\u0159e\u0161eny, je t\u0159eba p\u0159iznat, \u017ee za posledn\u00edch p\u00e1r let byl u\u010din\u011bn v\u00fdznamn\u00fd pokrok. (podle m\u011b, pokrok by mohl b\u00fdt v\u011bt\u0161\u00ed,o<\/b>kdyby lid\u00e9 v oboru v\u011bnovali trochu m\u00e9n\u011b pozornosti strojov\u00e9mu u\u010den\u00ed a o n\u011bco v\u00edce jin\u00fdm technik\u00e1m \u2014 ale to u\u017e je mimo t\u00e9ma).<\/i><\/p>\n

Vr\u00e1t\u00edm se do sv\u011bta DevOps a mikroslu\u017eeb. P\u0159ed n\u00e1mi le\u017e\u00ed obrovsk\u00fd probl\u00e9m, skr\u00fdvaj\u00edc\u00ed se jako slon v Kunstkammeru \u2014 proto\u017ee co \u010dasto sly\u0161\u00edm \u2014 \u201eprost\u011b si vezmi kubernetes a helm, a v\u0161echno bude v po\u0159\u00e1dku!\u201c Ale ne, nic nebude v po\u0159\u00e1dku, pokud v\u0161echno nech\u00e1me tak, jak je. Nav\u00edc analytick\u00e9 \u0159e\u0161en\u00ed tohoto probl\u00e9mu se zd\u00e1 b\u00fdt nepraktick\u00e9 kv\u016fli jeho slo\u017eitosti. Podobn\u011b jako u NLP, m\u011bli bychom nejprve p\u0159istoupit k tomuto probl\u00e9mu z\u00fa\u017een\u00edm vyhled\u00e1vac\u00ed oblasti \u2014 v tomto p\u0159\u00edpad\u011b vylou\u010den\u00edm zastaral\u00fdch permutac\u00ed.<\/p>\n

Jedna z v\u011bc\u00ed, kter\u00e1 m\u016f\u017ee pomoci \u2014 psal jsem minul\u00fd rok o nutnosti udr\u017eovat minim\u00e1ln\u00ed variabilitu mezi verzemi dod\u00e1van\u00fdmi klient\u016fm.<\/a><\/noindex>Tak\u00e9 je d\u016fle\u017eit\u00e9 poznamenat, \u017ee dob\u0159e navr\u017een\u00fd proces CI\/CD velmi pom\u00e1h\u00e1 p\u0159i sni\u017eov\u00e1n\u00ed variac\u00ed.
