I-Amazon Elastic Compute Cloud (EC2) yinxalenye ephambili ye- Amazon Web Services (AWS) - Inkampani yenkampani ye-cloud computing. Le nkonzo yewebhu inikezela amandla okwenza icomputer kwifini.
Njengoko ungabona nakweyiphi enye ipulatifti oyikhethayo, i-EC2 nayo ineengxaki kunye nemingcele. Masiqwalasele ngokucacileyo kwiingxaki ze-Amazon EC2 kula macandelo alandelayo.
Imida ye EC2
Ukunciphisa kwe-EC2 kunzima ukunqoba, kwaye kwahluke kwalabo bajamelene nabo ngelixa beqhuba i-hardware yakho. Ezi zithintelo zingonakalisa ukungahambi kunye nenhlalakahle yenkonzo yakho ngaphandle kokuphuhliswa kakuhle nokucwangciswa.
I-latencies phakathi kweziganeko, i-latency phakathi kokugcinwa kunye neziganeko, kunye nokusilela kwamandla anamandla anama-CPU angaphezu kwama-4 kunye ne-RAM ye-15 GB, yimiqathango emikhulu ye-EC2. Ingcinezelo ebangela yonke imiba ehlobene ne-latencies ifanayo; Iziganeko ezininzi ezingekho ndawo kwi-LAN ekwabelwana ngayo ukuncintisana.
I-intanethi kwi-EC2 ye-Amazon ixhaphake ngakumbi kuninzi lwee-LAN zendawo zithetha ukuba iipakethi zithintela ii-routers ezininzi kwaye zitshintsha endleleni yazo ukusuka kwelinye icala ukuya kwelinye. Inombolo nganye eyongezelelweyo ixhaswe phakathi kweziganeko nje nje ezimbalwa zee-millisecond ngaphezu kwexesha lokuhamba elipheleleyo lepakethi.
Ekubeni ininzi yedata kufuneka ihambe ukusuka ekupheleni komnye we-LAN ukuya kwenye, idatha yokuhamba idatha ixesha elide kunokuba lifuna ukuba likhokele kwiingxaki zokuxininisa ezibonakala kwi-intanethi.
Oku kungabi yinto enkulu yokusebenza ngokugqithiseleyo, kodwa kubaluleke kakhulu kubantu abaxhomekeke kwiifowuni ze-database ezikhawulezayo.
Ukuphuma kwangoko kwe-EC2
I-EC2 ibhekene nesantya esandula ukuphakamisa ukungathandabuzeki malunga nokuthembeka kweli qonga lefu. Imiba e-US-East-1 eneenkcukacha ezinxulumene noxhumano lwenethiwekhi; igama eliqaqambileyo njenge-Foursquare, Rapportive, uHeroku, neReddit ayifumanekanga okwethutyana.
Oku akuzange kube ngowokuqala kwe-EC2 ye-Amazon yokushiya eyashiywe ezimbalwa zeziqalo eziqhelekileyo zokuqalisa ukuyeka. Ukugqithiswa kwangaphambili kulo nyaka kwaqhubeka malunga neeyure ezingama-48 kwaye kwakukho mbi kakhulu kwimbali ye-computing yefu. Nangona kunjalo, kwakunenzuzo kwimveliso ethembele kule nkonzo ngeli xesha njengoko ukukhutshwa kweso sigqibo kusisombululo ngokukhawuleza. I-EC2 iingxaki ze-Amazon kunye nemigudu ayinqabile, kodwa kusekho kwiimeko ezithatha ixesha elide ukulungiswa, kukulahleka okukhulu ekuphuhlisweni kwetheknoloji yelifu kunye nabathengi.
Ukutshintshwa kweeyure ezingama-48 ezandul 'ukwenziwa kwezi nkonzo kuyisiganeko esisodwa esibuza ukuthembeka kwetheknoloji yekhompyutha yekhompyutha. Ukuphuma ngenxa yokukhanyisa Kodwa, ngokuqinisekileyo baye bafunda kwimpazamo yabo, kwaye asizange sibone into efana nayo.
Nangona i-Amazon ye-EC2 inkonzo yesevisi inekhono lokuguqula indlela kwiinkonzo ze-intanethi ezisetyenziselwa ngayo, kusenokuba neengxaki ezithile.
Ngenxa yoko, kucetyiswa ukuba abaphuhlisi bayinike ingcamango yesibini ngaphambi kokuba batshintshe kwi-EC2.
