Cloud Computing | 雲端運算

  • 雲端運算是什麼?
    簡單地說,雲端運算(Cloud Computing)就是通過互聯網(雲)向使用者或組織(伺服器、儲存、資料庫、網路、軟體、分析、人工智慧等)提供運算資源。雲端運算通常基於虛擬化技術快速部署資源或獲得服務。

    雲端運算服務可以通過公有雲、私有雲或混合雲提供幾種不同的方式運作。公有雲運算由擁有實體資料中心的協力廠商服務提供者(如Amazon Web Service、Microsoft Azure 或 Google Cloud)提供,他們擁有實體伺服器硬體,然後通過安全的互聯網連接線上銷售這些資源。在私有雲中,企業通過虛擬伺服器上運行任意數量的可用實體電腦上的應用程式,在自己的資料中心內構建雲。混合雲運算則是私有雲運算和公有雲雲算服務混合使用。

    作為 RightScale's 2018 State of the Cloud report的一部分,針對 997 名 IT 專業人員進行了深入調查,瞭解他們採用雲基礎架構和相關技術,有96% 的受訪者表示,在運行企業的各種服務時都使用了雲端運算的技術,不管是公有雲、私有雲或是混和雲。

  • 你為什麼需要它?誰需要它?
    雲端運算非常方便而且經濟 – 由於利用運算/儲存/網路資源的使用者不需要受限於空間距離而在定位在硬體周圍,因此硬體可以放在於遠端位置(易於維護且成本更低,甚至"外包"給公有雲供應商(如Amazon、微軟或Google等)。使用者和運算資源之間不需要任何特殊的硬體、無線網路連接或基礎設施,只需通過互聯網使用它即可。此外,因為使用者可以從任何位置遠端存取,透過在中心位置匯集處理,可以更有效率地分享和調配資源。相較於使用各自的實體電腦,雲端運算的方式可以節省更多的硬體資源。

    雲端運算要使用公有雲或私有雲、或是將兩者結合起來將取決於許多不同的因素。公有雲服務具有極高的成本效益,因為無須自行購買或維護硬體。使用者只需要為他們實際用到的運算資源付費,達成更大的彈性。 私有雲則可確保組織管理監控自己的資料安全,這些要求對於醫療和金融服務等有高度安全、隱私和適法性的行業中是必要的。多年來在資料中心投資了數百萬美元的大型公司也希望通過利用私有雲來保護自己的投資。

    混合雲可以提供兩者的優勢 – 組織可以在現場擁有和控制自己的資料,同時與公有雲服務連接使用不同的功能。混合雲的潛在缺點是管理和連接不同雲端平臺的複雜性將大幅增加。

  • 技嘉的特色
