  • 「雲端運算」 = 「網路」 = 「網路運算」 雲端運算不是技術 , 它是概念 它是一種 電腦運算的概念 ,而一種概念就會有許多不同的方式去實踐,這個時候才會有不同的技術衍伸出來。
  • 本質上就是代表 分散式運算 (distributed computing) 的概念。
  • [email_address] 是一項國際性的科學計畫,藉由 Internet 相連的成千上萬台電腦之計算能力,來分析由外太空傳來的無線電波,並試圖找出外太空可能存在的外星文明
  • 儲存空間的雲端服務( Storage as a Services ) Amazon S3(Simple Storage Service) (Twitter 有使用 ) 提供基礎架構的雲端服務( Infrastructure as a Services ) Amazon EC2(User 建立自己的作業系統, Amazon 負責管理實體伺服器和網路頻寬 ) 平臺即服務( Platform as a Services ) 代管用戶應用程式的執行平臺 ( 如 Salesforce 的 Force.com , M$ Azure , Google App Engine , Yahoo Application Platform) 軟體即服務( Software as a Services ) 目前最成熟的雲端服務 Google Apps
  • 降低成本 有了雲端計算環境後,用戶可依照自身的需求購入所需的計算資源,不但降低建置成本,小型企業也能擁有大企業級的資料中心 (Data Center) ,這對中小企業林立的台灣更顯重要。 高度自動化 在雲端計算的架構下,企業不需僱用人力維運自身的資訊中心,用戶端既不需要安裝多種軟體,也省去軟體升級等維護問題,一切都交給遠端的雲端維運中心照料,達成高度自動化。 高配置彈性 有了雲端計算環境,使用者利用簡易的電腦設備,便可自世上任一有網路的角落獲取所需的計算資源。在這種情況下,哪裡都可以是辦公室甚至是高速計算實驗室,大幅提高企業機關配置人力與資源的彈性,也能縮短城鄉的差距。 更佳的儲存空間 透過雲端計算環境,人們能在網路上儲存更多的資料,也不必為了增加資料儲存空間添購和整併設備而傷腦筋。 環保節能 雲端計算將過去散布於各機關單位的資訊中心集中管理規劃,有效地節省整體空間、電力、安全設備以及人力等資源。
  • 所有的資料都在雲端 - 隨時隨地存取 - 資料自動備份 - Anytime , anywhere , any device
  • 就不會有電腦壞掉,檔案全部遺失那種令人抓狂的窘境。
  • 類似以前的網路硬碟,但是更為強大 ! 更方便 !
  • Dropbox replaces: Emailing file attachments to yourself and other people Using USB drives to move files between computers Renaming files to keep a history of previous versions Complicated backup software and hardware And more!
  • Dropbox allows you to sync your files online and across your computers automatically. 2GB of online storage for free, with up to 100GB available to paying customers. Sync files of any size or type. Sync Windows, Mac and Linux computers. Automatically syncs when new files or changes are detected. Work on files in your Dropbox even if you’re offline. Your changes sync once your computer has an Internet connection again. Dropbox transfers will correctly resume where they left off if the connection drops. Efficient sync – only the pieces of a file that changed (not the whole file) are synced. This saves you time.
  • File Sharing Sharing files is simple and can be done with only a few clicks. Shared folders allow several people to collaborate on a set of files. You can see other people’s changes instantly. A “Public” folder that lets you link directly to files in your Dropbox. Control who is able to access shared folders (including ability to kick people out and remove the shared files from their computers). Automatically create shareable online photo galleries from folders of photos in your Dropbox.
  • Online Backup Dropbox backs up your files online without you having to think about it. Automatic backup of your files. Undelete files and folders. Restore previous versions of your files. 30 days of undo history, with unlimited undo available as a paid option.
  • Web Access A copy of your files are stored on Dropbox’s secure servers. This lets you access them from any computer or mobile device. Manipulate files as you would on your desktop – add, edit, delete, rename etc. Search your entire Dropbox for files. A “Recent Events” feed that shows you a summary of activity in your Dropbox. Create shared folders and invite people to them. Recover previous versions of any file or undelete deleted files. View photo galleries created automatically from photos in your Dropbox.
  • Security & Privacy Dropbox takes the security and privacy of your files very seriously. Shared folders are viewable only by people you invite. All transmission of file data and metadata occurs over an encrypted channel (SSL). All files stored on Dropbox servers are encrypted (AES-256) and are inaccessible without your account password. Dropbox website and client software have been hardened against attacks from hackers. Dropbox employees are not able to view any user’s files. Online access to your files requires your username and password. Public files are only viewable by people who have a link to the file(s). Public folders are not browsable or searchable.
  • The free Dropbox Mobile Apps lets you: Access your Dropbox on the go. View your files on your iPhone or iPod Touch. Download files for offline viewing. Take photos and videos and sync them to your Dropbox. Share links to files in your Dropbox. View interactive photo galleries. Sync downloaded files so they’re up-to-date.
  • HTC
  • 當所有服務都搬上了雲端,人們也都習慣使用雲端服務了以後,會造成什麼影響?
  • 具有 Thin Client 的終端裝置大量出現 Mobile Devices 更熱門 (iPhone / iPad …)
  • OS 的牽絆力大為減弱〈離開 Windows 再也不痛苦〉 瀏覽器的重要性與日俱增
  • 課題 : 安全性
  • 課題 : 服務穩定度 , 過度依賴
  • Apple 在北卡 North Carolina 建龐大的資料中心 ( 另 花費了 170 萬美金向一對夫妻收購了他們居住了 30 年的土地 ,最早他們已 1600 美元購買 ) 現今 Movie / Video Rental (streaming) Music in the cloud ? (Subscription)
  • Virtualization , SOA …
  • 最後祝大家都能夠像這位小姐一樣很優雅的…漫步在雲端 !
