Amazon Web Services is adding a home-grown NoSQL database to its ever-expanding roster of cloud computing offerings. DynamoDB is what Amazon CTO Werner Vogels called a “fully managed” NoSQL implementation the company built and tested over the years.

The demand for NoSQL databases is booming with the growth of big data and web applications: something of which Amazon and other tech providers are well aware. Amazon already offers a range of relational database services and SimpleDB, another home-grown, non-relational database, which is easy to use and powerful but has some domain scaling limitations. But NoSQL is built to scale along with unstructured web data and is also suited for the distributed nature of web applications.
