企業上云為什么是數字化轉型升級的第一步
3月17日我們分享了一篇文章,”無企業,不上云”,被各大平臺轉載分享,這讓我們看到了互聯網的熱情,也看到了企業對上云的渴望,艾銻無限作為阿里云的戰略合作伙伴,我們更樂意幫助企業上云,讓更多的企業邁向數字化時代.
我們相信每一家企業都是IT企業,每一家企業都是互聯網企業,每一家企業都是數字化企業,這一切的基礎都是基于云,云將會成為企業最重要的基礎設施,就像水、媒、電一樣的重要.IT外包
那為什么云對于企業來說如此重要呢,主要有以下五個方面:
1、應變力
云端快速部署、自由擴展的優勢,使網站、APP等應用上線、迭代更加靈活,提高了信息系統的運營效率。云以突出的應變能力,適應多變的企業信息化進程,降低試錯成本,加快研發進度,增強企業創新的信心。
2、穩定性
云環境為企業業務創造了一個穩定、可靠的空間,使用戶體驗更好,客戶滿意度顯著提升。互聯網產品獲得流量和用戶粘性的核心是用戶體驗,在線用戶流暢訪問,便捷操作,才會有較高的市場占有率。
3、性價比
云計算優異的性價比,為企業信息化大幅降低了成本。使企業可以把更多的資金,投入到業務創新中。傳統企業轉型升級存在著大量的不確定性,低成本的云計算幫助企業消除了資金上的顧慮。
4、安全性
轉型中的傳統企業,因對網絡環境不熟悉,擔心網絡攻擊、數據泄露等安全問題。云計算服務商有專業的技術和高效的服務體系,幫助企業保護數據安全、規避安全風險和提供海量數據查詢,企業可以專注于網站和應用程序,而不是基礎設施。
5、擴展性
在企業信息化的成本結構中,購買硬件軟件成本占比很高,而實際用于開發的支出就相應很低,并且耗費時間較長。如果完全基于云開架設IT系統,幾個小時就可完成基本框架。如果業務增加,就是直接購買服務器,邊際效益很低,采用云后,由于云計算的高擴展性,通過邊際效益可實現成本下降。
綜上所述,未來云就像我們用的水、電、媒一樣成為企業的必須品,也會是最重要的基礎設施一個部分,所以數字化轉型的企業,首先要上云,再考慮如何整合和重構企業內部的數據,從而讓計算起到主導作用,最終實現企業數字化轉型終極目標.
solaris中添加刪除磁盤和分區
如何在solaris中添加刪除磁盤和分區
建意你先看 IDE 和 SCSI 分配名稱
以下例子是格式化 Primary IDE Master 硬盤
查看 IDE 和 SCSI 分配名稱后,我們知道 Primary IDE Master 硬盤名稱是c0d0。
請先行 Login 成為 root user
# drvconfig ( configure the /devices directory )
# disks ( creates /dev entries for hard disks attached to the system )
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d0
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
1. c1t6d0
/pci@0,0/pci9004,8178@f/sd@6,0
Specify disk (enter its number): 0 ( 因為 Primary IDE Master 硬盤名稱是c0d0,所以選擇 0 )
AVAILABLE DRIVE TYPES:
0. other
Specify disk type (enter its number):0
( 正常應該是 0. DEFAULT 1. other,通常應該選擇DEFAULT,但是Solaris不明白我的硬盤是什么,所
以只有other可供選擇。)
我的IDE HardDisk架構如下:-
( 可以從BIOS Auto Detect查出來,通常都有LBA,LARGE,AUTO三種選擇,建意你使用Auto,因為不能大
過16Heads和不能大過63Sectoes )
