The newer fast data architectures differ significantly from big data architectures and the tried-and-true online transaction processing tools that fast data supplements. Understanding big data and fast data’s requirement changes will inform your foray into the hardware and software choices.
Big data architectures
Big data is about analyzing and gaining deeper insights from much larger pools of data than enterprises typically gathered in the past. Much of the data (e.g., social-media data about customers) is accessible in public clouds. This data, in turn, emphasizes speedy access and deemphasizes consistency, leading to a wide array of Hadoop big data tools. Thus, the following changes in architecture and emphasis are common:
