This session will begin with an introduction to non-relational (NoSQL) databases and compare them with relational (SQL) databases. We will also explain the fundamentals of Amazon DynamoDB, a fully managed NoSQL database service. Learn the fundamentals of DynamoDB and see the new DynamoDB console first-hand as we discuss common use cases and benefits of this high-performance key-value and JSON document store.

2. Agenda
• Brief history of data processing
• Relational (SQL) vs. nonrelational (NoSQL)
• Fully managed features of DynamoDB
• Customer use cases
• Demo – serverless applications
• Pricing and Free Tier

3. Data volume since 2010
• 90% of stored data generated in
last 2 years
• 1 terabyte of data in 2010 equals
6.5 petabytes today
• Linear correlation between data
pressure and technical innovation
• No reason these trends will not
continue over time

4. Timeline of database technology

Optimized for storage Optimized for compute
Normalized/relational Denormalized/hierarchical
Ad hoc queries Instantiated views
Scale vertically Scale horizontally
Good for OLAP Built for OLTP at scale
SQL NoSQL
