Historick\u00fd kontext a v\u00fdvoj<\/b><\/div>\n
Architektura mikroslu\u017eeb vznikla jako reakce na re\u00e1ln\u00e9 probl\u00e9my velk\u00fdch internetov\u00fdch spole\u010dnost\u00ed v polovin\u011b prvn\u00edho desetilet\u00ed 21. stolet\u00ed. Amazon p\u0159i rychl\u00e9m r\u016fstu na\u0159\u00eddil, aby v\u0161echny t\u00fdmy zp\u0159\u00edstup\u0148ovaly svou funkcionalitu v\u00fdhradn\u011b p\u0159es rozhran\u00ed slu\u017eeb \u2014 co\u017e se stalo jedn\u00edm ze z\u00e1kladn\u00edch stavebn\u00edch kamen\u016f.<\/div>\n
Stejn\u011b pou\u010dn\u00e1 je transformace Netflixu. V roce 2008 zp\u016fsobil rozs\u00e1hl\u00fd v\u00fdpadek datab\u00e1ze t\u00e9m\u011b\u0159 paral\u00fdzu jejich slu\u017eby p\u016fj\u010dov\u00e1n\u00ed DVD. Tato krize p\u0159im\u011bla Netflix p\u0159ej\u00edt z monolitick\u00e9 aplikace v Jav\u011b na mikroslu\u017eby. Rozd\u011blen\u00edm syst\u00e9mu na nez\u00e1visl\u00e9 slu\u017eby dok\u00e1zal izolovat chyby, samostatn\u011b \u0161k\u00e1lovat a nasazovat nov\u00e9 funkce bez ohro\u017een\u00ed cel\u00e9 platformy.<\/div>\n
V\u00fdvoj mikroslu\u017eeb byl \u00fazce spojen s kontejnerizac\u00ed. P\u0159\u00edchod Dockeru v roce 2013 p\u0159inesl lehk\u00fd bal\u00ed\u010dkovac\u00ed mechanismus pro slu\u017eby. Kubernetes (Google, 2014) pak poskytl orchestra\u010dn\u00ed prost\u0159ed\u00ed pro spr\u00e1vu tis\u00edc\u016f kontejner\u016f. Tyto technologie umo\u017enily re\u00e1ln\u00fd provoz mikroslu\u017eeb ve velk\u00e9m m\u011b\u0159\u00edtku.<\/div>\n
Dnes jsou mikroslu\u017eby dominantn\u00edm vzorem p\u0159i v\u00fdvoji v cloudu. Spole\u010dnosti jako Spotify, Airbnb \u010di Stripe ve\u0159ejn\u011b popsaly svou cestu k mikroslu\u017eb\u00e1m a vytvo\u0159ily z nich standard pro budov\u00e1n\u00ed \u0161k\u00e1lovateln\u00fdch podnikov\u00fdch aplikac\u00ed.<\/div>\n
Jak syst\u00e9my mikroslu\u017eeb komunikuj\u00ed<\/b><\/div>\n
Komunikace mezi slu\u017ebami je pro tuto architekturu kl\u00ed\u010dov\u00e1. Existuj\u00ed dva hlavn\u00ed vzory: synchronn\u00ed (po\u017eadavek-odpov\u011b\u010f) a asynchronn\u00ed (\u0159\u00edzen\u00e1 ud\u00e1lostmi).<\/div>\n

    Synchronn\u00ed komunikace:<\/b> Slu\u017eba ode\u0161le po\u017eadavek jin\u00e9 slu\u017eb\u011b a \u010dek\u00e1 na odpov\u011b\u010f (nej\u010dast\u011bji p\u0159es HTTP\/REST nebo gRPC). REST je roz\u0161\u00ed\u0159en\u00fd pro svou jednoduchost. gRPC (zalo\u017een\u00e9 na HTTP\/2) nab\u00edz\u00ed vy\u0161\u0161\u00ed v\u00fdkon d\u00edky bin\u00e1rn\u00ed serializaci a streamov\u00e1n\u00ed. Synchronn\u00ed p\u0159\u00edstup se snadno implementuje a lad\u00ed, ale vytv\u00e1\u0159\u00ed \u010dasovou z\u00e1vislost \u2014 pokud je volan\u00e1 slu\u017eba pomal\u00e1 nebo nedostupn\u00e1, volaj\u00edc\u00ed slu\u017eba z\u016fstane zablokovan\u00e1. Proto jsou nezbytn\u00e9 mechanismy odolnosti, jako nap\u0159\u00edklad circuit breaker<\/i> (p\u0159eru\u0161ova\u010d) a \u010dasov\u00e9 limity (timeouts<\/i>).<\/div>\n<\/li>\n

    Asynchronn\u00ed komunikace:<\/b> Odd\u011bluje slu\u017eby v \u010dase. Jedna slu\u017eba publikuje ud\u00e1lost do zprost\u0159edkovatele zpr\u00e1v (message broker, nap\u0159.
