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.
