雲端遷移是將數位業務營運轉移到雲端的過程。雲端遷移有點像實體遷移,只是這涉及將資料、應用程式和 IT 流程從某些資料中心遷移到其他資料中心,而不是打包和遷移實體產品。就像從較小的辦公室遷移到較大的辦公室一樣,雲端遷移需要大量的準備工作和前期工作,但是通常值得為之付出努力,從而節省成本並提高靈活性。
Most often, "cloud migration" describes the move from on-premise or legacy infrastructure to the cloud. However, the term can also apply to a migration from one cloud to another cloud.
在運算中,如果硬體或軟體已過時但仍在使用,則將其視為「舊版」。舊版產品和流程通常不如最新解決方案有效和安全。被迫執行舊系統的企業會有落後於競爭對手的風險。他們還面臨著更高的資料外洩的危險。
舊版軟體或硬體可能會變得不可靠、執行速度緩慢或可能不再受原始供應商的支援。例如,Windows XP 是舊版作業系統:於 2001 年發布,其功能已被更高版本的 Windows 超越,並且微軟不再透過發佈修補程式或更新來支援該作業系統。
基礎結構包括伺服器、網路設備、應用程式、資料庫以及任何其他關鍵業務軟體或硬體。傳統的基礎結構 (例如老化的伺服器或實體防火牆設備) 可能會減慢公司的業務流程。隨著原始供應商放棄對其產品的支援並停止發佈安全性修補程式,這也可能增加更多的安全性風險。
Legacy infrastructure is typically hosted on-premise, meaning it is physically located in buildings or on property where the organization operates. For instance, many businesses host an on-premise data center in the same building where their employees work.
Companies that rely on on-premise legacy infrastructure are unable to experience the benefits of cloud computing. Because of this, most enterprises today have made at least a partial migration to the cloud.
每個業務都有不同的需求,因此對雲端遷移將遵循略有不同的流程。雲端提供者可以幫助企業建立其遷移流程。大多數雲端遷移將包括以下基本步驟:
Some businesses turn off their on-premise infrastructure at the end of these steps, while others may keep legacy systems in place as backup or as part of a hybrid cloud deployment.
權威的資訊技術研究公司 Gartner 為組織遷移到雲端提供了 5 種選擇。這些雲端遷移策略通常稱為「5 R's」:
除了雲端遷移策略外,企業還需要確定遷移完成後雲端部署的外觀。
A hybrid cloud mixes two or more types of environments, combining public clouds, private clouds, or on-premise legacy data centers. For a hybrid cloud deployment to work well, integration must be tight across all deployed clouds and data centers – just as team members need especially tight communication if they are spread out across different offices.
A multi-cloud deployment combines two or more public clouds. (Public clouds are shared by more than one customer.) Multi-cloud can serve several purposes: redundancy/backup, cost savings, or leveraging features from different cloud providers, for instance.
僅從一個雲端供應商部署單一雲端對於企業而言不一定可行,但這是一種選擇。雲端提供者同時提供公共雲端和私有雲端–區別在於私有雲端不與任何其他業務共享。
Cloudflare offers a single control plane for the performance and security products necessary to make a move to the cloud successful – such as DNS, load balancing, the Cloudflare WAF, and others. These products are all integrated and can all be managed from a single dashboard (see a cloud migration case study). Cloudflare integrates easily with any type of cloud deployment – public cloud, private cloud, hybrid cloud, or multi-cloud.
