First read the two white papers, linked below, which gives you a nice overview of Big Data. Discuss what are the challenges in terms of current state of data generation, storage and retrieval?

Then focus on the data volume aspect of Big Data and choose one of the topics for discussing how to build the technology stack for your choice of topic.

• HDFS
• S3 / other AWS offering
• NoSQL databases such as MongoDB
• Vertical scaling (for either relational or noSQL DB)
• Horizontal scaling (for either relational or noSQL DB)
• In memory processing
• Data lakes

You should focus on finding the current trends and how people are using the technology to solve the problem of ever growing data. Remember to go deep and bring new knowledge to the class.
