Soki okutanaki na page oyo okanisaki okozua riche na quelque scheme ya get-rich-quick, naza na mawa ya ko décevoir yo. Lisolo oyo ekoloba mingimingi ndenge ya kokitisa ba factures na yo ya ba coûts ya cloud na 1 million ya dollars. Na kosalaka bongo, okozala essentiellement kobimisa million ya dollars ya likolo na revenu — oyo okoki kolekisa na kosomba cours na ngai en ligne na ndenge ya kozua riche na AWS ( lien na cours awa ).
Mbala mingi, ba bosanaka mpe ba comptabiliser ba coûts ya cloud na ebandeli ya ba projets ya ba Compagnies. Ankɛtɛ ya HashiCorp ya 2021 emonisi ete pene na 40% ya bakompanyi esalelaki mbongo mingi mpo na kofuta mbongo ya lipata na 2021 [ 1 ]. Na 2023, pene na ba entreprises nionso (94%) endimaki ete ezalaki kobebisa mbongo na cloud [ 1 ] mpe ata 30% ya ba coûts ya cloud ebebisamaki [ 2 ]. Dépense ya cloud ezalaki presque 500 milliards ya ba dollars na 2022 — yango wana tozali kolobela 150 milliards ya ba dollars oyo ebebisami na mbula!!
Oyo ezali kaka te soucis ya ba revenus oyo ezangi kasi pe ba pratiques ya mabe ya durability. 150 milliards ya ba dollars ya énergie ebebisami!
Ba résultats oyo etali ba entreprises minene lokola pe ya mike, kobanda na maturité ya mapata ya likolo tii na maturité ya mapata ya moke. Ezali kolobela AWS, kasi mitinda ndenge moko ekoki kosalelama na mopesi mosusu nyonso ya lipata. Na yango, soki eteni moko ya mosala na yo ezali na lipata, boye lisolo oyo ezali mpo na yo.
Nazali koloba na perspective ya ingénieur ya ba données, kasi ba apprentissage ndenge moko ekoki kosalelama na ba pratiques misusu ya ingénierie logicielle.
To plonge na kati.
Lolenge oyo ya facture ya cloud ekangamaka mingi mingi na ba entreprises ya minene mingi oyo esalaka na mokili mobimba na ba millions ya ba clients.
Mpo na kopesa yo likanisi, facture ya cloud ya $1 million ekoki kouta na mosala ya Spark ETL oyo ezali kosala ~1.5Tb na ngonga moko 24x7 mpo na mikolo 365 na mbula. Ndakisa mosusu ekoki kozala application oyo ezwaka bamiliare ya ba demandes na mokolo uta na bisika ebele na mokili.
Na entreprise moko ya munene, ezali na ba centaines ya ba applications na taille oyo — esali ba contrats ya ba milliards ya dollars na ba cloud-providers. Ndakisa, Airbnb ezalaki na elaka ya kobimisa 1,2 milliards ya ba dollars na ba ressources ya cloud na mibu mitano na suka ya 2019 [3 ].
Na Expedia tokitisaki ba frais ya ETL ya traitement ya ba données oyo efutaka 1,1 millions ya dollars na mbula na 100.000 dollars mpamba na mbula na kosalelaka ba pratiques ya optimisation. Yango eza réduction ya 91% ya coût!!
Ba entreprises nionso te nde ezalaka na ba applications ya taille munene boye mais imaginez kokata coût ya cloud na yo na 90% kaka pona application moko to pona entreprise na yo mobimba.
Kende kozua liste ya ba applications na yo ya talo mingi pe ko contester ba suppositions na yo ya design .
Mituna oyo nionso ezongaka na motuna ya motuya mingi: ndenge nini bakosalela application? Valeur ya commerce eza nini pona yango ezala? Ndenge nini programɛ yango ezali kosalisa biso tókokisa mokano moko boye?
Ya solo, mbala mingi mpenza biyano nyonso wana ezalaka polele te na ebandeli ya mosala moko; kasi yango wana design esengeli ntango nyonso kozala processus iteratif — ko permettre ba changements esalema sans soudure ndenge ekoki. Ba ingénieurs basengeli koyamba évolution mpe mbongwana, ko aligner développement ya application na impact.
Etape ya mibale ezali kopesa application ba ressources oyo esengeli mpe ko tuner yango na infrastructure oyo esengeli.
Lokola ozali ingénieur, yebá ndenge oyo ba calculer ba coûts ya cloud. Ndakisa, AWS epesaka ba instances spot, esika okoki kosala soumission mpo na prix ya cluster — yango ezali na tina mingi soki ozali na ba applications oyo ekoki ko tolérer ba fautes mpe flexible. Salelá yango soki okoki — AWS elobi ete mbongo ekitisami kino 90% [ 4 ].
Mwa makambo mosusu oyo okoki kotalela ezali:
Ezali na ba inconvénients moke to ata moko te na kosalela ba instances ya AWS Graviton. AWS etie mbongo mingi mpo na kosala ba processeurs oyo ezali na talo moke. Okoki kozwa kino 40% ya kokitisa mosolo ya lipata kaka na kobongola uta na processeur oyo esalemi na intel kino na processeur oyo esalemi na ARM [ 10 ].
Caveat seule na likambo oyo ezali que application na yo esengeli ezala compatible na ba processeurs basés na ARM oyo Graviton ezo tambola na yango. Soki ozali kosala na service géré lokola RDS to OpenSearch alors ezali na complication ata muke te na changement — AWS etali OS ya sous-jacent mpe compatibilité ya application. Soki ozali kotonga application na yo moko, alors okoki kozala na besoin ya ko recompiler ensemble selon langue nini ozali kosalela — Java na minoko misusu esengaka changement te alors que Python esengaka mua attention.
Enfin, kobosana te ko continuer ko surveiller ba coûts na yo pona ba sommets na ba surprises imprévues. Ntalo na mokolo ya 0 ya application na yo ekokesana na ntalo ya mokolo ya 170. Sala que ozala na suivi ya ba changements, pe o comprendre pourquoi changement ezali kosalema: est-ce que ezali ko stacking ba frais ya stockage s3 to ezali kaka ya mbala moko nsonge?
Bobongisa ba alertes oyo esengeli na ba guidebooks ya opérationnel !
Likambo ya motuya, kosalela bilembo ya bopesi ntalo mpo na kolandela mosolo na departema, projet, to zinga zinga. Bokima likama ya kosala marécage ya ba données esika coût ezali traçable te to esengaka mobembo molayi na ba systèmes ya journal ndenge na ndenge. Esengeli kozala mbangu mpe pete mpo na kozonga na ntalo nyonso ya bosengi.
Bisika nionso ozali kosala, ko équilibrer livraison ya ba fonctionnalités ya sika na optimisation ya oyo ya lelo ezali pasi. Nani azali pression te mpo na kopesa ba fonctionnalités ya sika ya quirky na vitesse ya lumière.
Kasi, ezali na ntina mingi mpo na ba ingénieurs mpe ba dirigeants bazua mikano na nko mpe na proactive na oyo etali ba projets na bango ya lelo, ko gérer ba risques mpe ba opportunités na ndenge ya malamu.
