Aukushintsha kwenethiwekhiiyidivayisi enweba inethiwekhi futhi ingahlinzeka ngezimbobo eziningi zokuxhuma kunethiwekhi engaphansi ukuze ixhume amakhompyutha amaningi.Inezici zesilinganiso esiphezulu sokusebenza nenani, ukuguquguquka okuphezulu, kulula kakhulu, futhi kulula ukuyisebenzisa.Ngakho-ke, yini indima yokushintshwa kwenethiwekhi esikhungweni sedatha?

Uma isixhumi esibonakalayo sokushintsha inethiwekhi sithola ithrafikhi eningi kunaleyo engakwazi ukusiphatha, iswishi yenethiwekhi izokhetha ukuyigcina kunqolobane noma ukushintsha kwenethiwekhi ukuyilahla.Inqolobane yoshintsho lwenethiwekhi ngokuvamile ibangelwa isivinini esihlukile sokusebenzelana kwenethiwekhi, ithrafikhi yeswishi yenethiwekhi iqhuma ngokuzumayo noma ukudluliswa kwethrafikhi okuningi kuya koyedwa.

Inkinga evame kakhulu edala ukubhafa ekushintsheni kwenethiwekhi ukushintsha okungazelelwe kuthrafikhi eminingi kuya koyedwa.Isibonelo, uhlelo lokusebenza lwakhiwe kuma-node amaningi weqoqo leseva.Uma enye yamanodi ngesikhathi esisodwa icela idatha kusuka ekushintsheni kwenethiwekhi yawo wonke amanye amanodi, zonke izimpendulo kufanele zifike ekushintsheni kwenethiwekhi ngesikhathi esifanayo.Uma lokhu kwenzeka, ukugcwala kwethrafikhi yawo wonke amaswishi enethiwekhi kuzogcwala imbobo yokushintsha inethiwekhi yomfakisicelo.Uma iswishi yenethiwekhi ingenawo amabhafa anele wokuphuma, iswishi yenethiwekhi ingase ilahle ithrafikhi ethile, noma iswishi yenethiwekhi ingase ikhulise ukubambezeleka kohlelo lokusebenza.Izibhafa ezanele zokushintsha kwenethiwekhi zingavimbela ukulahleka kwephakethe noma ukubambezeleka kwenethiwekhi okubangelwa amaphrothokholi asezingeni eliphansi.

Inkundla yokushintsha isikhungo sedatha yesimanje kakhulu ixazulula le nkinga ngokwabelana ngokushintsha kwebhafa yeswishi yenethiwekhi.Iswishi yenethiwekhi inesikhala se-buffer pool esabelwe imbobo ethile.Amabhafa okushintshaniswa okwabelwana ngawo amaswishi enethiwekhi ayahluka kakhulu phakathi kwabathengisi abahlukene nezinkundla.

Abanye abakhiqizi bokushintsha inethiwekhi bathengisa amaswishi enethiwekhi aklanyelwe izindawo ezithile.Isibonelo, ezinye izinguquko zenethiwekhi zinokucutshungulwa kwebhafa okukhulu, okulungele izimo zokudlulisa eziningi kuya kokukodwa endaweni ye-Hadoop.Endaweni ekwazi ukusabalalisa ithrafikhi, amaswishi enethiwekhi awadingi ukuthi akhiphe amabhafa kuleveli yokushintsha.

Isigcinalwazi sokushintsha kwenethiwekhi sibaluleke kakhulu, kodwa ayikho impendulo efanele yokuthi singakanani isikhala esisidingayo ukuze sishintshe inethiwekhi.Ibhafa yokushintsha inethiwekhi enkulu isho ukuthi inethiwekhi ngeke ilahle noma iyiphi ithrafikhi, futhi kusho nokuthi ukubambezeleka kokushintsha kwenethiwekhi kuyanda-idatha egcinwe iswishi yenethiwekhi idinga ukulinda ngaphambi kokuba idluliselwe phambili.Abanye abalawuli benethiwekhi bakhetha izigcinalwazi ezincane zokushintshwa kwenethiwekhi ukuze zivumele uhlelo lokusebenza noma ukucutshungulwa kwephrothokholi ukuze kwehliswe ithrafikhi ethile.Impendulo elungile iwukuqonda iphethini yethrafikhi yeswishi yenethiwekhi yohlelo lokusebenza bese ukhetha iswishi yenethiwekhi evumelana nalezi zidingo.
