4. 當某幾台硬體資源發生故障,軟體用資源管理的方式自動切換到其他正常運作的硬體
這樣的概念形成一個雲端概念,就是永遠不斷線的概念
因為這種雲端的概念對於主機公司維護有很大的優點
他們也不斷的在推廣這種型態的主機
所以你可能會發現雲端主機的硬體效能會比共享型態的主機效能稍微好
有關於雲端主機Cloud hosting和虛擬私人伺服器VPS的差異
以下是我詢問bluehost技術支持他們給我的回應
(0:52) [frank] what is different cloud and vps
(0:53) [Darrin] Cloud hosting
Cloud hosting offers unlimited ability to handle high traffic or traffic spikes.
More web traffic should never slow you down.
Here’s how it works:
A team of servers (called a cloud) work together to host a group of websites.
This allows multiple computers to work together to handle high traffic levels or
spikes for any particular website.
For customer to harness the power of the cloud without the complexity of VPS &
Dedicated servers. As your online presence grows, amp up your cloud usage with the
click of a button.
Either pick a more powerful plan, or add CPU and RAM a la cart as needed.
All without having to worry about reboots, cryptic usage fees, or downtime.
(0:53) [frank] Business Pro cloud vs VPS standard which performance is better
(0:53) [Darrin] VPS
VPS hosting guarantees the customer a portion of the server, while a Dedicated
Server means the customer will own the entire server.
Both of these services will greatly increase speed and
(0:55) [frank] cloud's uptime is 100% right?
(0:55) [Darrin] VPS, is alway better
(0:55) [frank] cloud plan share cpu to every user right?
(0:56) [Darrin] we don't guarantee a 0 uptime it's ™.8
(0:57) [Darrin] we don't guarantee 100 percent it's 99.8
(0:57) [frank] cloud plan share cpu to every user right?
(1:9) [Darrin] yes that's correct
(1:11) [frank] can you send this chat history to my email [email protected]
(1:12) [Darrin] you would be able to get that at the end of the chat
(1:13) [frank] ok thanks
(1:13) [frank] no question done
共享主機 Shared
這是最便宜,最典型,最多人在使用的主機方案
你和其他人分享主機硬體資源,你可能不會得到保證的CPU time
雖然速度不是最快的,但是對於大部份的人,你的網站安裝在共享主機是最好的選擇
4/9
