2024 Tus sau: Lynn Donovan | [email protected]. Kawg hloov kho: 2023-12-15 23:47
A huab thov , los yog huab app, yog ib qho software program nyob qhov twg huab -raws li thiab hauv zos Cheebtsam ua haujlwm ua ke. Cov qauv no tso siab rau cov chaw taws teeb tswj hwm rau kev ua cov logic uas tau nkag los ntawm lub vev xaib browser nrog kev txuas mus txuas ntxiv hauv internet.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qee qhov piv txwv ntawm kev siv huab?
Piv txwv ntawm Cloud Computing Services
- Amazon EC2 - Virtual IT.
- Google App Engine - Daim ntawv thov hosting.
- Google Apps thiab Microsoft Office Online - SaaS.
- Kua iCloud - Network cia.
- DigitalOcean - Servers (Iaas/PaaS)
Ib tug kuj yuav nug, dab tsi yog huab raws li system? Huab - raws yog ib lo lus uas hais txog cov ntawv thov, cov kev pabcuam lossis cov peev txheej tsim muaj rau cov neeg siv ntawm kev thov hauv Is Taws Nem los ntawm a huab xam cov chaw zov me nyuam cov servers.
Tom qab ntawd, ib tus tuaj yeem nug, koj yuav tsim cov ntawv thov huab raws li cas?
Nco ntsoov ua raws tsib kauj ruam los tsim kom muaj huab-npaj daim ntawv thov architecture:
- Tsim daim ntawv thov raws li kev sau cov kev pabcuam.
- Decouple cov ntaub ntawv.
- Xav txog kev sib txuas lus ntawm cov khoom siv.
- Qauv thiab tsim rau kev ua tau zoo thiab scaling.
- Ua kom muaj kev ruaj ntseg systemic hauv daim ntawv thov.
Puas yog WhatsApp yog ib daim ntawv thov huab?
Feem ntau ntawm kev xa xov thiab hu apps zoo li Skype thiab WhatsApp kuj yog raws ntawm huab infrastructure. Tag nrho koj cov lus thiab cov ntaub ntawv raug muab khaws cia rau ntawm qhov chaw muab kev pabcuam kho vajtse es tsis yog ntawm koj tus kheej lub cuab yeej. Qhov no tso cai rau koj nkag mus rau koj cov ntaub ntawv los ntawm txhua qhov chaw hauv internet.

Dab tsi yog qhov txawv ntawm huab huab pej xeem thiab huab ntiag tug?
Lub huab ntiag tug yog huab huab kev pabcuam uas tsis koom nrog lwm lub koom haum. Los ntawm qhov sib txawv, huab huab pej xeem yog huab huab kev pabcuam uas qhia cov kev pabcuam suav nrog cov neeg siv khoom sib txawv, txawm tias txhua tus neeg siv cov ntaub ntawv thiab cov ntawv thov khiav hauv huab tseem zais los ntawm lwm cov neeg siv huab
Pej xeem huab vs huab ntiag tug yog dab tsi?
Cov neeg siv huab ntiag tug muaj huab rau lawv tus kheej. Los ntawm qhov sib txawv, huab huab pej xeem yog huab huab kev pabcuam uas qhia cov kev pabcuam suav nrog cov neeg siv khoom sib txawv, txawm tias txhua tus neeg siv cov ntaub ntawv thiab cov ntawv thov khiav hauv huab tseem zais los ntawm lwm cov neeg siv huab
Tus neeg thov kev thov yog dab tsi?
Ib daim ntawv thov tus thov kev pab yog ib daim ntawv thov nyob ib leeg uas khiav ntawm lub tshuab neeg siv khoom thiab tau teeb tsa ua haujlwm raws li J2EE tivthaiv. Tus neeg thov kev thov yog siv los ua cov haujlwm, xws li kev tswj hwm lossis kev tswj hwm
Dab tsi yog qhov txawv ntawm kev thov synchronous thiab asynchronous thov?
Synchronous: Ib qho kev thov synchronous thaiv tus neeg siv khoom kom txog thaum ua haujlwm tiav. Asynchronous Ib qho kev thov asynchronous tsis thaiv tus neeg siv khoom xws li browser teb. Lub sijhawm ntawd, tus neeg siv tuaj yeem ua lwm yam haujlwm. Hauv qhov xwm txheej zoo li no, javascript cav ntawm browser tsis raug thaiv
