1、OpenStackUNIT 1OverviewOpenStack的這是個(gè)用方式程式語言寫成云端運(yùn)算軟體，使用Apache證。這東西可以用、很多缺陷、是個(gè)試用版，趕快來試試看吧。 - Joshua McKenty使用程式語言寫就的Nova，基本上是亞馬遜彈性云端運(yùn)算的仿制品。在Clark看過NASA的Nova程式碼之后，對(duì)于Nova跟Rackspace本身正在進(jìn)行的開放式己。間的高相似度感到相當(dāng)，久久無法自O(shè)penStack？OpenStack是一個(gè)國(guó)家航空航天局和Rackspace合作研發(fā)的，以Apache證，并且是一個(gè)OpenStack是一個(gè)云開放源代碼項(xiàng)目。管理的項(xiàng)目，它不是一個(gè)。這個(gè)項(xiàng)目

2、由幾個(gè)主要的組件組合起來完成一些具體的工作。OpenStack通過一個(gè)web界面提供資源管理，通過一個(gè)儀表板管理整個(gè)數(shù)據(jù)中心中的計(jì)算、等資源。廠商的支持有超過200家廠商加入OpenStack項(xiàng)目。包括：AMD, Brocade Communications Systems, CanonicalCisco, Dell, EMC, Ericsson, Groupe Bull, HP, IBM, Inkel, NEC, Rackspace Hosting,Red Hat, SUSE Linux, VMware, and Yahoo!OpenStack的用戶PayPal / eBayNASACERN
