Amazon Dynamo DB is now available in South America.

Recently, web applications generate and consume ever-increasing amounts of data. For example: just a couple of thousand users can play an online game at the start, the load on the database is small, and one server can handle it. But, with the increasing popularity of the game, the number of users can quickly increase to millions, and the load on the database - to tens, hundreds of thousands of reads and writes per second. In such a situation, there is an urgent need to scale up the storage system.



In January 2012, Amazon launched Dynamo DB in its cloud. This is a NoSQL database that solves the problem of scaling and performance. Now this service is available in the South American region.



Since this is a cloud service, using Dynamo DB provides the following benefits:

• Easy to scale
• Low data access latency
• Built-in back-up
• Built-in monitoring
• Pay-as-you-Go: you only need to pay for the resources consumed

For high performance and HA (high availability), data is stored on SSD disks and replicated between three data centers in the region.



Amazon DynamoDB organizes data into tables that are composed of elements, and each element has one or more attributes:
