Exploring AWS !!
Day 47:
Amazon DynamoDB — Part 3
DynamoDB for high scaled systems like amazon.com:
If you have below needs, then try going for DynamoDB:
Users — 1 million +
Data Volume — TB, PB, EB
Locally — Global
Performance — Microsecond latency
Request Rate — million/second
Access — mobile, IoT, devices, scale-up and down
Dev access — Instant API Access
Economics — Pay-as-you-go
Customers rely on DynamoDB to support mission critical workloads, example, Banking and Finance — fraud detection, user transaction, mainframe offloading (Used by — Capital One, Vanguard, Fannie Mae), Gaming, software and internet, ad-tech, retail, media and entertainment.
