Streamingleverant\u00f6ren Netflix lagrar sina videor f\u00f6r optimal leverans vid olika internethastigheter och uppspelningsenheter i olika l\u00e4nder. Uppl\u00f6sningar, kvalitetsniv\u00e5er och format<\/a>. Utvecklade kodade plattformen \"Reloaded\" i ungef\u00e4r sju \u00e5r. Under tiden har Netflix last dock tiodubblats tack vare en expansion till fler marknader och betydligt mer inneh\u00e5ll. Enligt Netflix tekniska blogg har detta orsakat problem. De ansvariga utvecklarna har d\u00e4rf\u00f6r utvecklat en ny kodningsplattform kallad \"Cosmos<\/a>\" skapades.<\/p>\n\n\n\n

Som Frank San Miguel f\u00f6rklarar f\u00f6r Cosmos-teamet var Reloadeds gamla arkitektur utformad enbart f\u00f6r att skala ljud- och videoinneh\u00e5ll s\u00e5 bra som m\u00f6jligt. Den monolitiska arkitekturen gjorde det dock mycket sv\u00e5rare att inf\u00f6ra nya funktioner. Dessutom har det team som ansvarar f\u00f6r kodningen vuxit betydligt under de senaste \u00e5ren, vilket innebar att s\u00e4rskilt nya medlemmar praktiskt taget inte hade n\u00e5gon \u00f6verblick \u00f6ver den f\u00f6r\u00e5ldrade Reloaded-arkitekturen. Ansvaret f\u00f6r detta var framf\u00f6r allt att applikationslogiken och infrastrukturkoden samordnades.<\/p>\n\n\n\n

Arkitekturer f\u00f6r mikrotj\u00e4nster som en f\u00f6rebild<\/h2>\n\n\n\n

P\u00e5 grund av de stora problemen best\u00e4mde sig teamet f\u00f6r en helt ny utveckling i st\u00e4llet f\u00f6r att se \u00f6ver den befintliga arkitekturen. Den moderna mikrotj\u00e4nstarkitekturen valdes som modell. F\u00f6rutom de faktiska kodningsuppgifterna g\u00f6r detta det m\u00f6jligt att modul\u00e4rt l\u00e4gga till ytterligare tj\u00e4nster, inklusive ett verktyg f\u00f6r \u00f6vervakning och verktyg f\u00f6r kontinuerlig leverans. Detta b\u00f6r g\u00f6ra det m\u00f6jligt att utveckla ny kod direkt i produktionsmilj\u00f6n.Bidrag<\/a> kan importeras utan ytterligare ingrepp.<\/p>\n\n\n\n

Trots likheterna \u00e4r Cosmos-tj\u00e4nster inte mikrotj\u00e4nster. Applikationsdata och dess beroenden \u00e4r ocks\u00e5 separerade fr\u00e5n andra system i Netflix kodningsverktyg, precis som i mikrotj\u00e4nster, men tj\u00e4nsterna anv\u00e4nder tydligt definierade API:er f\u00f6r att utbyta data.<\/p>\n\n\n\n

Det mycket ber\u00e4kningsintensiva arbete som sker vid sidan av kodningen laddar sina beroenden som Docker-containrar. Beroende p\u00e5 uppgiftens storlek \u00e4r det p\u00e5 Netflix flera tusen olika beh\u00e5llare som lagras i en molnbaserad databehandling<\/a> milj\u00f6. Enligt utvecklarna tar en k\u00f6rning ofta flera dagar f\u00f6r s\u00e4rskilt stora filer.<\/p>\n\n\n\n

Utvecklingen av Cosmos inleddes 2018 och de f\u00f6rsta testerna i produktmilj\u00f6n p\u00e5b\u00f6rjas 2019. Den egentliga lanseringen av systemet, som d\u00e5 helt och h\u00e5llet kommer att ers\u00e4tta kodningsplattformen Reloaded, kommer att \u00e4ga rum under innevarande \u00e5r 2021.<\/p>","protected":false},"excerpt":{"rendered":"
