Dostawca us\u0142ug strumieniowych Netflix przechowuje swoje filmy w celu zapewnienia optymalnej dostawy przy r\u00f3\u017cnych pr\u0119dko\u015bciach Internetu i na r\u00f3\u017cnych urz\u0105dzeniach odtwarzaj\u0105cych w r\u00f3\u017cnych Rozdzielczo\u015b\u0107, poziomy jako\u015bci i formaty<\/a>. Przez oko\u0142o siedem lat zajmowa\u0142em si\u0119 kodowaniem platformy \"Reloaded\". W mi\u0119dzyczasie jednak obci\u0105\u017cenie Netflixa wzros\u0142o dziesi\u0119ciokrotnie dzi\u0119ki ekspansji na kolejne rynki i znacznie wi\u0119kszej ilo\u015bci tre\u015bci. Wed\u0142ug bloga in\u017cynier\u00f3w Netflixa, spowodowa\u0142o to problemy. Odpowiedzialni za to programi\u015bci opracowali wi\u0119c now\u0105 platform\u0119 kodowania o nazwie \"Kosmos<\/a>\" stworzone.<\/p>\n\n\n\n

Jak wyja\u015bnia Frank San Miguel w imieniu zespo\u0142u Cosmos, stara architektura Reloaded zosta\u0142a zaprojektowana wy\u0142\u0105cznie do skalowania tre\u015bci audio i wideo tak dobrze, jak to tylko mo\u017cliwe. Jednak monolityczna architektura znacznie utrudnia\u0142a wprowadzanie nowych funkcji. Ponadto, zesp\u00f3\u0142 odpowiedzialny za kodowanie znacznie si\u0119 powi\u0119kszy\u0142 w ci\u0105gu ostatnich kilku lat, co oznacza\u0142o, \u017ce zw\u0142aszcza nowi cz\u0142onkowie nie mieli praktycznie \u017cadnego wgl\u0105du w przestarza\u0142\u0105 architektur\u0119 Reloaded. Odpowiedzialne za to by\u0142o przede wszystkim po\u0142\u0105czenie logiki aplikacji z kodem infrastruktury.<\/p>\n\n\n\n

Architektura mikroserwis\u00f3w jako wz\u00f3r do na\u015bladowania<\/h2>\n\n\n\n

Ze wzgl\u0119du na powa\u017cne problemy, zesp\u00f3\u0142 zdecydowa\u0142 si\u0119 na ca\u0142kowicie nowy projekt zamiast rewizji istniej\u0105cej architektury. Jako model wybrano nowoczesn\u0105 architektur\u0119 mikroserwis\u00f3w. Opr\u00f3cz samych zada\u0144 zwi\u0105zanych z kodowaniem, umo\u017cliwia to modu\u0142owe dodawanie kolejnych us\u0142ug, w tym narz\u0119dzia do monitorowania i narz\u0119dzia dla potoku ci\u0105g\u0142ego dostarczania. Powinno to umo\u017cliwi\u0107 tworzenie nowego kodu bezpo\u015brednio w \u015brodowisku produkcyjnym.Sk\u0142adki<\/a> mog\u0105 by\u0107 importowane bez dodatkowych interwencji.<\/p>\n\n\n\n

Pomimo podobie\u0144stw, us\u0142ugi Cosmos nie s\u0105 mikroserwisami. Dane aplikacji i jej zale\u017cno\u015bci s\u0105 r\u00f3wnie\u017c odseparowane od innych system\u00f3w w narz\u0119dziu koduj\u0105cym Netflix, podobnie jak w mikroserwisach, ale us\u0142ugi wykorzystuj\u0105 jasno zdefiniowane API do wymiany danych.<\/p>\n\n\n\n

Wysokoobliczeniowa praca, kt\u00f3ra wyst\u0119puje obok kodowania, \u0142aduje swoje zale\u017cno\u015bci jako kontenery Docker. W zale\u017cno\u015bci od wielko\u015bci zadania, w Netflixie jest to kilka tysi\u0119cy r\u00f3\u017cnych kontener\u00f3w, kt\u00f3re s\u0105 przechowywane w cloud computing<\/a> \u015brodowisko. W przypadku szczeg\u00f3lnie du\u017cych plik\u00f3w, jak twierdz\u0105 tw\u00f3rcy, uruchomienie programu zajmuje cz\u0119sto kilka dni.<\/p>\n\n\n\n

Prace rozwojowe nad Cosmosem rozpocz\u0119\u0142y si\u0119 w 2018 r., a wst\u0119pne testy w \u015brodowisku produktowym w 2019 r. W\u0142a\u015bciwy rollout systemu, kt\u00f3ry nast\u0119pnie ca\u0142kowicie zast\u0105pi platform\u0119 kodowania Reloaded, nast\u0105pi w bie\u017c\u0105cym roku 2021.<\/p>","protected":false},"excerpt":{"rendered":"
