What is DynamoDB?
DynamoDB is a fully managed, Internet scalable, easily administered, and cost effective
NoSQL database. It is a part of database as a service-offering pane of Amazon Web Ser-
vices.
The next diagram shows how Amazon offers its various cloud services and where Dy-
namoDB is exactly placed. AWS RDS is a relational database as a service over the Internet
from Amazon, while Simple DB and DynamoDB are NoSQL databases as services. Both
SimpleDB and DynamoDB are fully managed, nonrelational services. DynamoDB is build
considering fast, seamless scalability, and high performance. It runs on SSDs to provide
faster responses and has no limits on request capacity and storage. It automatically parti-
tions your data throughout the cluster to meet expectations, while in SimpleDB, we have a
storage limit of 10 GB and can only take limited requests per second.
Also, in SimpleDB, we have to manage our own partitions. So, depending upon your need,
you have to choose the correct solution.
