Tundub, et mikroteenuste buumi tipp on m\u00f6\u00f6das. Me ei loe enam mitu korda n\u00e4dalas postitusi \"Kuidas ma muutsin oma monol\u00fc\u00fcdi 150 teenuseks\". N\u00fc\u00fcd kuulen j\u00e4rjest enam m\u00f5istlikke m\u00f5tteid: \"Ma ei j\u00e4ta monol\u00fc\u00fcdi maha, ma lihtsalt hoolin efektiivsusest\". Oleme isegi n\u00e4inud mitmeid migratsioone mikroteenustest tagasi monol\u00fc\u00fcdi<\/a><\/noindex>. Suurelt rakenduselt v\u00e4iksematele teenustele minnes tuleb lahendada mitu uusi probleeme. Loetleme need v\u00f5imalikult l\u00fchidalt.
\n<\/a><\/noindex><\/p>\n

Seadistamine: alates p\u00f5hirektsioonist kvantmehhaanikani<\/h1>\n

\nP\u00f5hiandmebaasi ja taustaprotsessiga rakenduse seadistamine oli \u00fcsna selge protsess. Jagasin readme'i GitHubis - ja sageli \u00fche tunni, maksimaalselt paar tunni p\u00e4rast t\u00f6\u00f6tas k\u00f5ik ning ma alustasin uut projekti. Koodi lisamine ja k\u00e4ivitamine, v\u00e4hemalt algkeskkonna jaoks, toimub samal p\u00e4eval. Kuid kui me julgeme mikroteenustele minna, t\u00f5useb esialgne k\u00e4ivitamise aeg taevasse. Jah, n\u00fc\u00fcd on meil Docker koos orkestreerimisega ja K8 masinate klaster, kuid k\u00f5igile algajatele programmeerijatele on see oluliselt keerulisem. Paljudele noorematele arendajatele on see koorem, mis on t\u00f5eliselt tarbetu keerukus.<\/p>\n

S\u00fcsteemi on keeruline m\u00f5ista<\/h1>\n

\nV\u00f5tame hetkeks meie noore arendaja. Monol\u00fc\u00fctiliste rakendustega oli vea korral kergesti j\u00e4lgitav ja lihtne alustada silumist. N\u00fc\u00fcd on meil teenus, mis suhtleb teise teenusega, mille kaudu midagi j\u00e4rjekorda pannakse s\u00f5numite bussis, mis t\u00f6\u00f6tleb teist teenust - ja seal tekib viga. Me peame k\u00f5ik need osad kokku panema, et l\u00f5puks teada saada, et teenus A t\u00f6\u00f6tab versioonis 11, samas kui teenus E ootab juba versiooni 12. See on t\u00e4iesti erinev minu tavap\u00e4rasest konsolideeritud logist: pean kasutama interaktiivset terminali\/silumist, et minna protsessis samm-sammult edasi. Silumine ja m\u00f5istmine on tegelikult keerulisemaks muutunud.<\/p>\n

Kui ei saa siluda, siis v\u00f5ib-olla katsetame neid<\/h1>\n

\nPidev integratsioon ja pidev arendus on muutumas tavap\u00e4raseks. Enamik uusi rakendusi, mida ma n\u00e4en, loovad iga uue v\u00e4ljaandega automaatselt testid ja n\u00f5uavad, et testid l\u00e4biksid ja vaadataks \u00fcle enne registreerimist. Need on suurep\u00e4rased protsessid, millest ei saa loobuda, need on olnud suur muutus paljudele ettev\u00f5tetele. Kuid n\u00fc\u00fcd, et t\u00f5eliselt teenust testida, pean ma t\u00f5stma oma rakenduse t\u00e4iskomplekti \u00fcles. Kas m\u00e4letate seda uut inseneri, kellel on 150 teenusega K8 klaster? Noh, n\u00fc\u00fcd \u00f5petame meie CI-s\u00fcsteemile, kuidas k\u00f5ik need s\u00fcsteemid \u00fcles t\u00f5sta, et kontrollida, kas k\u00f5ik tegelikult t\u00f6\u00f6tab. T\u00f5en\u00e4oliselt on see liiga palju vaeva, seega testime lihtsalt iga osa eraldi: olen kindel, et meie spetsifikatsioonid on piisavalt head, API-d puhtad ja teenuse t\u00f5rge on eraldatud ja ei m\u00f5juta teisi.<\/p>\n

K\u00f5ikidel kompromissidel on m\u00f5juv p\u00f5hjus. \u00d5igus?<\/h1>\n

\nOn palju p\u00f5hjuseid, miks liikuda mikroteenustele. Olen n\u00e4inud, et seda tehakse suurema paindlikkuse, meeskondade skaleerimise, tootlikkuse ja t\u00f6\u00f6 paremaks vastupidavuseks. Kuid tegelikkuses oleme investeerinud k\u00fcmneid aastaid monoliitsete arendust\u00f6\u00f6riistade ja praktikate arendamisse, mis j\u00e4tkavad arengut. T\u00f6\u00f6dan professionaalidega erinevates tehnoloogiates. Tavaliselt r\u00e4\u00e4gime skaleerimisest, kuna nad seisavad silmitsi Postgresi andmebaasi \u00fche s\u00f5lme piirangutega. Suur osa vestlustest on seotud andmebaasi skaleerimisega<\/a><\/noindex>.<\/p>\n

Aga mind huvitab alati nende arhitektuur. Millisel \u00fclemineku etapis mikroteenustele nad on. On huvitav t\u00e4hele panna, et \u00fcha rohkem insenere \u00fctleb, et nad on oma monoliitrakendusega rahul. Paljudele toovad mikroteenused kasu ja eelised kaaluvad \u00fcles migratsiooniteed k\u00fctused. Kuid isiklikult, palun tooge mulle minu monoliitne rakendus, koht rannas - ja olen t\u00e4iesti \u00f5nnelik.
