Amazon DynamoDB is a fully managed NoSQL database service provided by AWS that delivers single-digit millisecond performance at any scale. It provides fast and predictable performance with seamless scalability and flexible data modeling. DynamoDB allows users to provision the necessary throughput capacity and pay only for what they use, with no upfront costs and no need to provision, operate, or scale the underlying database infrastructure.

3. Amazon DynamoDB is the result of everything we’ve learned from
building large-scale, non-relational databases for Amazon.com and
building highly scalable and reliable cloud computing services at AWS.”

12. Tell us the performance you want
Let us handle the rest

13. Every DynamoDB table has:
• Provisioned write capacity
• Provisioned read capacity
• No limit on storage

14. Change your throughput capacity as needed
Pay for throughput capacity and storage used

17. Change scale with the click of a button

18. When you run your own database, you need to:
• Try and forecast the scale you need
• React quickly if you get it wrong
• Invest time and money learning how to scale your
database

19. Benefits:
• Safety; you know you’re ready
Risks:
• Buy too much capacity
• Lose development resources to
scale testing/planning
• Do more work than necessary

20. Benefits
• Lower costs if all goes well
Risks:
• Last-minute scaling emergencies
• How does your database behave at an
unexpected scale?
