9. NIST WG 定義 Big Data
• Big Data refers to the inability of tradit
ional data architectures to efficiently
handle the new datasets.
• characteristics (4Vs)
– volume
– variety
– velocity
– variability
10. NIST WG 還強調了…
• Big Data consists of extensive datase
ts -
primarily in the characteristics of volu
me, variety, velocity, and/or variability
-
that require a scalable architecture for
efficient
storage, manipulation, and analysis.
11. NIST WG 還強調了…
• The Big Data paradigm consists of th
e distribution of data systems across
horizontally
coupled, independent resources to ac
hieve the scalability needed for the eff
icient
processing of extensive datasets.

17. Big Data 跟 Cloud Computing
• 從資料的角度
– 資料存儲量
– 跨機房存取
– 異地同步
18. Big Data 跟 Cloud Computing
• 從運算規模
及基礎架構
– 硬體投資
– 超高運算量
– 分散運算
26. 架構實踐 - 資料來源多元性
• 找到正確資料源
– Website / Mobile
Service
– Open Data
– Open API
• 資訊收集工具
– Centralized Log
Management
– Spider / Crawler
– 3rd Application
