Big Data Challenges
The major challenges associated with big data are as follows:
- Velocity – It moves extremely fast through various sources such as online systems, sensors, social media, web clickstream capture, and other channels
- Variety – It’s made of many types of data from many sources – structured and semi-structured, as well as unstructured (think emails, text messages, documents and the like)
- Volume – It may (but not always) involve terabytes to petabytes (and beyond) of data.
- Complexity – It must be able to traverse multiple data centers, the cloud and geographical zones
