Study Notes
Clustered Computing for Big Data
- Individual computers are often inadequate for handling big data due to its high storage and computational needs.
- Big data clustering software combines the resources of many smaller machines to provide benefits such as:
- Resource Pooling: combining available storage space, CPU, and memory to process large datasets.
- High Availability: providing fault tolerance and availability guarantees to prevent hardware or software failures.
- Easy Scalability: allowing for horizontal scaling by adding additional machines to the group.
What Is Big Data?
- Big data refers to a collection of data sets that are too large and complex to process using traditional database management tools or applications.
- A "large dataset" means a dataset that is too large to process or store with traditional tooling or on a single computer.
- The scale of big datasets varies significantly from organization to organization and is constantly shifting.
- Big data is characterized by the 3V's and more:
- Volume: large amounts of data (e.g., zeta bytes, massive datasets).
- Velocity: data is live streaming or in motion.
- Variety: data comes in many different forms from diverse sources.
- Veracity: the accuracy and trustworthiness of the data.
