Momwe ndale zazaka za zana la 19 zidakhudzira malo apakati masiku ano

Kuchokera kwa womasulira

Wokondedwa Habrazhiteliki! Popeza uku ndikuyesa kwanga koyamba kutumiza zomwe zili pa Habré, chonde musaweruze mwankhanza kwambiri. Kutsutsa ndi malingaliro amavomerezedwa mosavuta mu LAN.

Posachedwa, Google yalengeza za kupezeka New data center ku Salt Lake City, Utah. Awa ndi amodzi mwa malo amakono a data omwe makampani monga Microsoft, Facebook, Apple, Yahoo, ndi ena adayikapo, omwe ali pamzere wofanana ndi 41st kufanana ku United States.

Iliyonse mwamakampaniwa ikuyika mabiliyoni a madola m'mizinda inayi:

• Microsoft adayika $3.5 biliyoni kupita ku amodzi mwama data akulu kwambiri ku Des Moines, Iowa, ndi $ 750 miliyoni m'malo opangira data, yomwe ili ku Cheyenne, Wyoming.
• apulo adayika $1.35 biliyoni kupita ku malo apamwamba kwambiri a data ku Des Moines.
• Google imayika $ 1 biliyoni ku malo opangira data pafupi ndi Omaha, Nebraska, kuwonjezera pa ndalama zake zaposachedwa ku Salt Lake City.
• National Center for Atmospheric Research NCAR anamanga 1.5 petaflop supercomputer ku Cheyenne, ndipo ndi imodzi mwamakompyuta apamwamba kwambiri padziko lonse lapansi.
• US National Security Agency ikugwira ntchito chosungira chachikulu cha data yanzeru ku Salt Lake City, Utah.

Nanga ndi chiyani chomwe chimapangitsa kufanana kwa 41 kukhala kwapadera kwambiri, kuchititsa makampani osiyanasiyana kuyika mabiliyoni a madola kumanga malo osungiramo data m'mizindayi?

Yankho ndiloti magalimoto ambiri omwe amachokera kum'mawa kupita kumadzulo kwa United States ndi kubwerera amadutsa malo onsewa kupyolera mumagulu akuluakulu a zingwe za fiber optic zomwe zimakhala ndi makampani ambiri a telecom, monga: AT&T, Verizon, Comcast, Level 3, Zayo, Fibertech, Windstream ndi ena.

Izi CHIKWANGWANI chamawonedwe maukonde zomangamanga amapereka deta malo mwayi chiwerengero chachikulu cha njira lonse, kulimbikitsa ndalama mkombero - malo deta zambiri kukopa anthu ambiri, zomwe zimabweretsa kumanga zambiri CHIKWANGWANI chamawonedwe backbones, amene kachiwiri kumabweretsa kumanga malo deta zambiri. .

Chifukwa chiyani zimphona zonse za telecom zidasankha kupeza misewu yawo yayikulu m'njira iyi kudutsa ku US? Chifukwa chilichonse mwa zingwezi chimayendera mobisa m'njira yopitilira kumanja pafupifupi mamita 60 m'mphepete mwa njanji yoyamba yodutsa njanji, yomwe idamalizidwa mu 1869. Boma la US linapereka ufulu ku malowa ku njanji ya Union Pacific posayina Pacific Railroad Act ya 1862. Ndipo ngati ndinu kampani yolumikizirana ndi telefoni mukuyang'ana kuti mupange msana watsopano ku United States mu 2019, pali kampani imodzi yokha yomwe mudzafunika kugwirizanitsa ntchito yanu ndi: Union Pacific. Malo ang'onoang'ono awa amawoloka dziko la United States, monga momwe tawonera m'mapangidwe a njanji awa a 1864:

Chitsanzo cha malo ochezera a patelefoni ngati awa ndi teleport yayikulu ya EchoStar ku Cheyenne, Wyoming. EchoStar imagwiritsa ntchito ma satellites 25 a geostationary kuulutsa zomwe zili ndi makanema. Anagula malo akuluakulu pafupi ndi Union Pacific kumanja kwa njira, kuwalola kuti alowe muzitsulo za transcontinental optical zokwiriridwa pafupi ndi njanji.

Pachithunzi chomwe chili pansipa mutha kuwona bwino mzere wogawa mizere ya katundu wa EchoStar, wakumpoto womwe ukugwirizana ndi Union Pacific pomwe.

Chitsanzo china cha kuyandikira koteroko ndi Microsoft data centers ndi NCAR supercomputer center ku Wyoming. Onsewa ali mkati mwa kilomita imodzi ya njanji ya Union Pacific:

N'chifukwa chiyani njanji inamangidwa motsatira 41st parallel, kuchokera ku Iowa kupita ku California?
Kuyambira 1853, United States yachita mayeso kuti mudziwe njira yabwino ya njanji yatsopanoyi - motsatira 47, 39, 35 ndi 32. Mu 1859, Mlembi wa Nkhondo ku United States, Jefferson Davis, adathandizira kwambiri njira yakummwera yochokera ku New Orleans kupita ku San Diego - inali yaifupi, panalibe mapiri aatali omwe angagonjetsedwe panjirayo, ndipo panalibe chipale chofewa chomwe chikanawonjezera mtengo wokonza zatsopano. misewu ya njanji. Koma m'zaka za m'ma 1850, palibe munthu wakumpoto yemwe angavotere njira yakummwera, yomwe ingathandize chuma cha akapolo a Confederacy, ndipo palibe msilikali wakumwera amene angavotere njira yakumpoto. Mavutowa anapitirizabe mpaka pamene Nkhondo Yapachiweniweni ya ku America inayamba. Mayiko akumwera atasiya mgwirizano mu 1861, andale akumpoto otsalawo adavota mwachangu mokomera Railroad Act ya 1862, yomwe idakhazikitsa poyambira msewu wodutsa ku Council Bluffs, Iowa, ndi njira yochokera kumadzulo kupita kummawa motsatira Route 41. -kufanana.

Chifukwa chiyani Council Bluffs? Panali mizinda yambiri yofunitsitsa kupikisana nawo pa mwayi umenewu. Koma a Council Bluffs anasankhidwa chifukwa chigwa cha Plate River chakumadzulo kwa mzindawu chinkatsetsereka pang’onopang’ono kufupi ndi mapiri a Rocky, n’kupereka magwero abwino a madzi opangira masitima apamtunda. Madzi omwewo tsopano amagwiritsidwa ntchito kuziziritsa kwa adiabatic malo amakono a data panjira iyi.

Njanji yoyamba itamalizidwa, Western Union nthawi yomweyo idakhazikitsa njira yoyamba yolumikizirana matelefoni mkati mwa njanjiyo, ndipo posakhalitsa idatumiza ma telegalamu onse kuchokera kumalekezero a kontinenti kupita kwina. Pambuyo pake, pamene AT&T idamanga matelefoni akutali kumayambiriro kwa zaka za zana la XNUMX, adamangidwanso m'mphepete mwa njanji iyi. Misewu ikuluikulu imeneyi inakula ndipo inamangidwapo mpaka inakhala misewu ikuluikulu yolumikizirana yomwe ilipo masiku ano m’derali.

Umu ndi momwe zisankho za mfundo zomwe zidapangidwa zaka zoposa 150 zapitazo zatsimikizira komwe mabiliyoni ambiri a madola akuyikidwa m'malo amakono a data masiku ano.
