Isu tinowanzo kuita BinPack - CPU uye Spread - AZ; neiyi mutemo, mabasa anoiswa zvakanyanya sezvinobvira pamushini mumwe paCPU. Kana zvichidikanwa kugadzira muchina mutsva, unogadzirwa munzvimbo itsva yekuwanikwa.
Rodha balancer mhando β sarudza Application Load Balancer.

Service Auto Scaling - service scaling parameters. Sarudza Configure Service Auto Scaling kuti ugadzirise kuverenga kwaunoda sevhisi. Isu tinoisa hushoma uye huwandu hwehuwandu hwemabasa pakuyera.
IAM basa reSevhisi Auto Scaling - sarudza AWSServiceRoleForApplicationAutoScaling_ECSService.
Automatic task scaling policy - mitemo yekuyera. Kune mhando mbiri:
- Target tracking -yekuteedzera tarisiro metrics (CPU/RAM kushandiswa kana nhamba yezvikumbiro zvebasa rega rega). Semuenzaniso, isu tinoda kuti avhareji processor mutoro ive 85%, kana yave yakakwirira, mabasa matsva anozowedzerwa kudzamara yasvika painotariswa kukosha. Kana mutoro wakadzikira, ipapo mabasa anozobviswa, pane zvinopesana, kunze kwekunge dziviriro kubva pakudzika pasi yakagoneswa (Dzima chikero-mukati).
- Step scaling - kuita kune chimwe chiitiko chisingatarisirwi. Pano iwe unogona kugadzirisa maitiro kune chero chiitiko (CloudWatch Alarm), kana ikaitika, unogona kuwedzera kana kubvisa nhamba yakatarwa yemabasa, kana kutsanangura nhamba chaiyo yemabasa.
Basa rinogona kunge riine mitemo yakawanda yekuyera, izvi zvinogona kubatsira, chinhu chikuru ndechekuona kuti hazvipesani nemumwe.

Kana iwe ukatevera mirairo uye ukashandisa iwo akafanana Docker mufananidzo, sevhisi yako inofanirwa kudzosera peji seizvi.
- Isu takagadzira template zvichienderana nekuti machina ese ari musevhisi anotangwa. Isu takadzidzawo maitiro ekugadzirisa michina kana template yachinja.
- Isu takagadzirisa kugadziridzwa kweiyo nzvimbo yekumisa chiratidzo, saka mukati meminiti mushure mekuigamuchira, ese anomhanya mabasa anobviswa pamushini, saka hapana chinorasika kana kukanganiswa.
- Takasimudza chibalancer kuti tigovere mutoro wacho zvakaenzana pamichina.
- Isu takagadzira sevhisi inomhanya panzvimbo, iyo inoderedza mutengo wemuchina nekatatu.
- Isu takagadzirisa autoscaling mumativi ese maviri kubata basa rakawedzera pasina kuunza mitengo yekudzikisa.
- Isu tinoshandisa Capacity Provider kuitira kuti application igadzirise zvivakwa (michina) uye kwete imwe nzira kutenderedza.

Kana iwe uine spikes dzinofungidzirwa mukutakura, semuenzaniso uri kushambadzira mune yakakura email mushandirapamwe, unogona kuseta kuyera ne. .
Iwe unogona zvakare kuyera zvichienderana nedata kubva munzvimbo dzakasiyana dzehurongwa hwako. Somuenzaniso, tine kushanda vashandisi ve mobile application. Dzimwe nguva mushandirapamwe unotumirwa kune 1M+ vanhu. Mushure mekugovera kwakadaro, pane nguva dzose kuwedzera kukuru kwezvikumbiro kune API, sezvo vazhinji vashandisi vanopinda mukushandiswa panguva imwe chete. Saka kana tikaona kuti kune zvakatonyanya zviratidziro zvakajairwa mumutsara wekutumira zviziviso zvekusimudzira, isu tinokwanisa kubva tangotanga akati wandei mamwe machina uye mabasa kuti agadzirire mutoro.
Ini ndichafara kana iwe ukandiudza mune zvakataurwa nyaya dzinonakidza dzekushandisa nzvimbo dzenzvimbo uye ECS kana chimwe chinhu nezve kuyera.
Munguva pfupi iri kutevera kuchave nezvinyorwa nezve magadzirisiro atinoita zviuru zvezviitiko zvekuongorora pasekondi pane yakawanda isina server stack (nemari) uye kuti kuendesa masevhisi kunoshanda sei uchishandisa GitLab CI uye Terraform Cloud.
Bhalisa kwatiri, zvichave zvinonakidza!
