Amazon Elastic Compute Cloud (EC2) ndi mbali yapakati ya Amazon Web Services (AWS) - malo a cloud computing platform. Utumiki wa webusaitiwu umapereka mphamvu yodabwitsa ya kompyuta mu mtambo.
Monga momwe mungaone pa nsanja ina iliyonse imene mumasankha, EC2 imakhalanso ndi mavuto ndi zofooka. Tiyeni tiwone bwinobwino mavuto a Amazon EC2 m'magulu otsatirawa.
Zoperewera za EC2
Zolephera za EC2 ndi zovuta kuthetsa, ndi zosiyana ndi zomwe zinayang'anizana pamene mukugwiritsira ntchito hardware yanu. Kuletsa izi kungakhale kovulaza kuti zinthu zisasinthe komanso kukhala bwino kwa ntchito yanu popanda chitukuko chabwino ndi kukonzekera.
Zomwe zimachitika pakati pa zochitika, zovuta pakati pa yosungirako ndi zochitika, komanso kusowa kwa mphamvu zamphamvu zomwe zili ndi CPUs ndi 15 GB RAM, ndizo zoperewera kwambiri za EC2. Chimene chimayambitsa nkhani zonse zokhudzana ndi latencies ndi chimodzimodzi; Maselo angapo omwe sali malo omwe ali nawo mu LAN yogawana akukhamukira ku bandwidth.
Makompyuta a EC2 a Amazon akufalikira kuposa ma LAN ambiri omwe amasonyeza kuti mapaketi amagunda maulendo angapo komanso amasintha njira yawo kuchokera ku nthawi ina kupita ku ina. Nthendayi iliyonse yowonjezera pakati pa zochitika ndi zochepa zokha za millisecond kuposa nthawi yonse ya ulendo wa pakiti.
Popeza kuti deta yambiri imayenda kuchoka kumapeto ena a LAN kupita ku yina, deta yoyendayenda ndi yaitali kwambiri kuposa momwe imafunira kutsogolera mavuto owonongeka omwe amapezeka pa intaneti.
Izi sizingakhale zovuta kwambiri pa ntchito zowonongeka, koma zimakhala zovuta kwambiri kwa anthu omwe amadalira maulendo ofulumira.
Kutuluka Kwaposachedwa kwa EC2
EC2 inayang'anizana posachedwa posonyeza kukayikira za kudalirika kwa nsanja yamtambo. Maiko a US-East-1 omwe anakumana ndi nkhani zokhudzana ndi kugwirizanitsa; Dzina lalikulu liyamba ngati Foursquare, Rapportive, Heroku, ndi Reddit silinali kupezeka kwa kanthawi.
Uku sikunali koyambirira koyamba kwa maiko a Amazon omwe anasiya masewera ochepa otchuka omwe anasiya kuima. Kutuluka koyambirira kwa chaka chino kwadutsa maola 48 ndipo kunali koipitsitsa m'mbiri ya cloud computing. Komabe, zinali zopanda phindu pazinthu zogwirizana ndi ntchitoyi nthawi ino pamene kutsegulidwa kunathetsedwa mofulumira. EC2 Mavuto a Amazon ndi maulendo ake ndi osowa, koma nthawi zina zomwe zimatenga nthawi yaitali kuti zithetsedwe, ndizopweteka kwambiri kuti chitukuko cha mtambo ndi wogulitsa chikhale chonchi.
Kusokonezeka kwa maola 48 kwaposachedwa ndi ntchito imodzi yomwe imayesayesa kudalirika kwa teknoloji yamakono yojambula. Kuthamangitsidwa chifukwa cha kuwala Koma, ndithudi iwo adaphunzira kuchokera ku kulakwitsa kwawo, ndipo sitinapezeke kuti tiwone china chomwecho kachiwiri.
Ngakhale ntchito ya EC2 yogwira ntchito imatha kusintha kwambiri njira imene intaneti imayendetsera ntchito, imakhalabe ndi zovuta zina.
Choncho, tikulimbikitsidwa kuti opanga amupatse lingaliro lachiwiri musanayambe kugwira ntchito kwa EC2.
