Yaz\u0131l\u0131mda Karma\u015f\u0131kl\u0131k Neden Hak Edilmelidir?<\/h2>\n

Yaz\u0131l\u0131m geli\u015ftirirken neden en karma\u015f\u0131k mimarileri se\u00e7iyoruz? Yaz\u0131l\u0131mda karma\u015f\u0131kl\u0131k kontrol edilmedi\u011finde projeleri nas\u0131l \u00e7\u0131kmaza sokar? \u0130\u015fte yan\u0131tlar.<\/p>\n

Yaz\u0131l\u0131mda Karma\u015f\u0131kl\u0131k Nedir ve Neden Ka\u00e7\u0131n\u0131lmal\u0131d\u0131r?<\/h2>\n

Yaz\u0131l\u0131m d\u00fcnyas\u0131nda yeni bir projeye ba\u015flarken hepimiz en g\u00fcncel teknolojileri, en haval\u0131 mimari desenleri (design patterns) ve en geli\u015fmi\u015f k\u00fct\u00fcphaneleri kullanmak isteriz. Ancak, bu istek genellikle projenin erken a\u015famalar\u0131nda b\u00fcy\u00fck bir felaketle sonu\u00e7lan\u0131r. Yaz\u0131l\u0131mda karma\u015f\u0131kl\u0131k, bir sistemin anla\u015f\u0131lmas\u0131n\u0131, bak\u0131m\u0131n\u0131n yap\u0131lmas\u0131n\u0131 ve de\u011fi\u015ftirilmesini zorla\u015ft\u0131ran her t\u00fcrl\u00fc yap\u0131sal durumu ifade eder. Fred Brooks\u2019un \u00fcnl\u00fc “No Silver Bullet” (G\u00fcm\u00fc\u015f Kur\u015fun Yoktur) makalesinde belirtti\u011fi gibi, karma\u015f\u0131kl\u0131\u011f\u0131 iki temel kategoriye ay\u0131rabiliriz: Zorunlu karma\u015f\u0131kl\u0131k (essential complexity) ve yapay karma\u015f\u0131kl\u0131k (accidental complexity). <\/p>\n

Zorunlu karma\u015f\u0131kl\u0131k, \u00e7\u00f6zmeye \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131z i\u015f probleminin kendisinden kaynaklan\u0131r. \u00d6rne\u011fin, bir bankac\u0131l\u0131k sistemindeki yasal mevzuatlar veya karma\u015f\u0131k faiz hesaplama form\u00fclleri zorunlu bir karma\u015f\u0131kl\u0131k yarat\u0131r. Bu durumdan ka\u00e7\u0131nman\u0131z neredeyse imkans\u0131zd\u0131r. Di\u011fer yandan, yapay karma\u015f\u0131kl\u0131k ise tamamen bizim verdi\u011fimiz teknik kararlar\u0131n bir sonucudur. Hen\u00fcz on aktif kullan\u0131c\u0131s\u0131 bile olmayan bir e-ticaret sitesi i\u00e7in mikroservis (microservices) mimarisi kurmaya \u00e7al\u0131\u015f\u0131rsan\u0131z, kendi elinizle yapay bir karma\u015f\u0131kl\u0131k yaratm\u0131\u015f olursunuz. Bu durum, yaz\u0131l\u0131m geli\u015ftirme s\u00fcrecini ciddi \u015fekilde yava\u015flat\u0131r, hata yapma riskini art\u0131r\u0131r ve proje b\u00fct\u00e7esini h\u0131zla t\u00fcketir.<\/p>\n

Bu nedenle, yaz\u0131l\u0131mda karma\u015f\u0131kl\u0131k her zaman hak edilmelidir. Basit bir problemi \u00e7\u00f6zmek i\u00e7in gereksiz derecede karma\u015f\u0131k ara\u00e7lar kullanmak, sine\u011fi \u00f6ld\u00fcrmek i\u00e7in top atmaya benzer.

Sonu\u00e7 olarak, sadelik her zaman ilk hedefiniz olmal\u0131d\u0131r.<\/p>\n

Erken a\u015famada eklenen her soyutlama katman\u0131 (abstraction layer), her yeni veritaban\u0131 ve her harici servis, sistemin bak\u0131m maliyetini katlayarak art\u0131r\u0131r. \u00d6rne\u011fin, hen\u00fcz veri taban\u0131n\u0131zda sadece birka\u00e7 bin sat\u0131r veri varken NoSQL veya da\u011f\u0131t\u0131k veritaban\u0131 sistemlerine ge\u00e7i\u015f yapmak, sorgu yazmay\u0131 zorla\u015ft\u0131rmaktan ba\u015fka bir i\u015fe yaramaz.

Peki, bir projeye ba\u015flarken sadeli\u011fi nas\u0131l koruyabiliriz? \u0130lk kural olarak, her zaman en basit \u00e7al\u0131\u015fan modeli (MVP – Minimum Viable Product) hedeflemelisiniz.

Karma\u015f\u0131kl\u0131k Seviyesini Belirleyen Ger\u00e7ek D\u00fcnya Kriterleri Nelerdir?<\/h2>\n
Peki, yaz\u0131l\u0131mda karma\u015f\u0131kl\u0131k seviyesini art\u0131rmaya karar verirken hangi somut kriterleri g\u00f6z \u00f6n\u00fcnde bulundurmal\u0131y\u0131z?

Bu durumda monolitik (tek par\u00e7a) bir mimari ile devam etmek en do\u011frusudur.<\/p>\n
\u0130kinci kriter ise veri trafi\u011fi ve i\u015flem hacmidir. Saniyede sadece 5-10 i\u015flem yapan bir sistem i\u00e7in CQRS (Command Query Responsibility Segregation – Komut Sorgu Sorumluluklar\u0131n\u0131n Ayr\u0131lmas\u0131) deseni uygulamak gereksizdir. \u00c7\u00fcnk\u00fc bu desen, veri yazma ve okuma i\u015flemlerini ay\u0131rarak sistemi karma\u015f\u0131kla\u015ft\u0131r\u0131r. \u00dc\u00e7\u00fcnc\u00fc olarak, i\u015f alan\u0131n\u0131n (domain) karma\u015f\u0131kl\u0131\u011f\u0131 belirleyicidir.

Ancak basit bir i\u00e7erik y\u00f6netim sistemi (CMS) veya blog sitesi i\u00e7in DDD kullanmak projeyi ba\u015ftan \u00e7\u0131kmaza sokmak demektir.

T\u00fcrkiye’deki b\u00fcy\u00fck e-ticaret ve teknoloji \u015firketlerinin geli\u015fim s\u00fcre\u00e7lerine bakt\u0131\u011f\u0131m\u0131zda, bu prensibin ne kadar hayati oldu\u011funu net bir \u015fekilde g\u00f6r\u00fcr\u00fcz. Bu \u015firketlerin hi\u00e7biri faaliyetlerine ilk g\u00fcn y\u00fczlerce mikroservis ve devasa Kubernetes cluster’lar\u0131 (k\u00fcmeleri) ile ba\u015flamad\u0131. \u0130lk y\u0131llar\u0131nda, h\u0131zl\u0131ca pazara \u00e7\u0131kabilmek ve fikirlerini do\u011frulamak i\u00e7in tek bir monolitik uygulama kulland\u0131lar. Zamanla kullan\u0131c\u0131 say\u0131s\u0131 milyonlara ula\u015ft\u0131\u011f\u0131nda ve monolitik yap\u0131 art\u0131k \u00f6l\u00e7eklenemez hale geldi\u011finde, mimariyi par\u00e7a par\u00e7a mikroservislere d\u00f6n\u00fc\u015ft\u00fcrd\u00fcler.<\/p>\n
Bu d\u00f6n\u00fc\u015f\u00fcm esnas\u0131nda her bir mikroservisin s\u0131n\u0131rlar\u0131, ger\u00e7ek trafik verilerine ve ekiplerin sorumluluk alanlar\u0131na g\u00f6re belirlendi. \u00d6rne\u011fin, \u00f6deme sistemi (payment gateway) \u00e7ok kritik ve y\u00fcksek trafik alan bir b\u00f6l\u00fcm oldu\u011fu i\u00e7in ilk olarak o par\u00e7a monolitten ayr\u0131\u015ft\u0131r\u0131ld\u0131. Bu durum, karma\u015f\u0131kl\u0131\u011f\u0131n ad\u0131m ad\u0131m ve hak edilerek kazan\u0131ld\u0131\u011f\u0131n\u0131n en g\u00fczel kan\u0131t\u0131d\u0131r. E\u011fer bu \u015firketler ilk g\u00fcn mikroservis mimarisi ile yola \u00e7\u0131ksalard\u0131, muhtemelen da\u011f\u0131t\u0131k sistemlerin getirdi\u011fi a\u011f gecikmesi (network latency) ve veri tutarl\u0131l\u0131\u011f\u0131 (data consistency) gibi karma\u015f\u0131k problemlerle ba\u015f edemeyip pazarda ba\u015far\u0131s\u0131z olacaklard\u0131.

Yaz\u0131l\u0131mda Karma\u015f\u0131kl\u0131k Y\u00f6netimi Hakk\u0131nda S\u0131k\u00e7a Sorulan Sorular<\/h2>\n
Mikroservis mimarisine ne zaman ge\u00e7i\u015f yapmal\u0131y\u0131z?<\/h3>\n
Mikroservis mimarisine ge\u00e7i\u015f yapmak i\u00e7in iki temel \u015fart\u0131n sa\u011flanmas\u0131 gerekir. Birincisi, monolitik uygulaman\u0131z\u0131n art\u0131k dikey veya yatay olarak \u00f6l\u00e7eklenememesi ve performans darbo\u011faz\u0131 yaratmas\u0131d\u0131r. \u0130kincisi ise, yaz\u0131l\u0131m ekibinizin b\u00fcy\u00fcyerek tek bir kod taban\u0131 \u00fczerinde \u00e7ak\u0131\u015fmadan \u00e7al\u0131\u015fmakta zorlanmas\u0131d\u0131r. E\u011fer ekibiniz 10 ki\u015fiden azsa ve trafik sorununuz yoksa, mikroservis mimarisi size faydadan \u00e7ok zarar getirecektir.<\/p>\n
Yaz\u0131l\u0131mda teknik bor\u00e7 (technical debt) her zaman k\u00f6t\u00fc bir \u015fey midir?<\/h3>\n
Hay\u0131r, teknik bor\u00e7 her zaman k\u00f6t\u00fc de\u011fildir. T\u0131pk\u0131 finansal bor\u00e7lar gibi, teknik bor\u00e7lar da do\u011fru y\u00f6netildi\u011finde i\u015finizi h\u0131zland\u0131rabilir. Pazara h\u0131zl\u0131 girmek ve fikirlerinizi test etmek i\u00e7in bilin\u00e7li olarak baz\u0131 teknik bor\u00e7lar alabilirsiniz (\u00f6rne\u011fin test yaz\u0131m\u0131n\u0131 ertelemek veya basit bir mimari se\u00e7mek). Ancak, bu bor\u00e7lar\u0131 i\u015fler b\u00fcy\u00fcd\u00fc\u011f\u00fcnde geri \u00f6demeli (refactoring yapmal\u0131) ve sistemin s\u00fcrd\u00fcr\u00fclebilirli\u011fini sa\u011flamal\u0131s\u0131n\u0131z.<\/p>\n
“KISS” ve “YAGNI” prensipleri karma\u015f\u0131kl\u0131\u011f\u0131 \u00f6nlemede nas\u0131l yard\u0131mc\u0131 olur?<\/h3>\n
KISS (Keep It Simple, Stupid – Basit Tut, Aptalca Olsun) prensibi, bir problemi \u00e7\u00f6zerken her zaman en sade \u00e7\u00f6z\u00fcm\u00fc tercih etmeniz gerekti\u011fini savunur. YAGNI (You Aren’t Gonna Need It – Buna \u0130htiyac\u0131n\u0131z Olmayacak) prensibi ise, gelecekte ihtiya\u00e7 duyabilece\u011finizi d\u00fc\u015f\u00fcnd\u00fc\u011f\u00fcn\u00fcz \u00f6zellikleri \u015fimdiden kodunuza eklememenizi s\u00f6yler. Bu iki prensip, hak edilmemi\u015f karma\u015f\u0131kl\u0131\u011f\u0131 \u00f6nlemedeki en b\u00fcy\u00fck yard\u0131mc\u0131lar\u0131n\u0131zd\u0131r.<\/p>\n
Kodun gere\u011finden fazla karma\u015f\u0131k oldu\u011funu nas\u0131l anlar\u0131z?<\/h3>\n
E\u011fer bir koda yeni bir \u00f6zellik eklemek g\u00fcnler s\u00fcr\u00fcyorsa, k\u00fc\u00e7\u00fck bir de\u011fi\u015fiklik yapt\u0131\u011f\u0131n\u0131zda sistemin alakas\u0131z yerlerinde hatalar (bugs) olu\u015fuyorsa veya yeni i\u015fe ba\u015flayan bir geli\u015ftiricinin projeye adapte olmas\u0131 haftalar al\u0131yorsa, o kod taban\u0131 a\u015f\u0131r\u0131 karma\u015f\u0131k demektir. Bu durum, acilen sadele\u015ftirme (refactoring) yap\u0131lmas\u0131 gerekti\u011finin en net g\u00f6stergesidir.<\/p>\n
