Fundamentals of AWS

Learn about the core AWS's services like compute, storage, networking services and how they work with other services like Identity, Mobile, Routing, and Security. This module provides you with a good grasp an all you need to know of AWS services.
This module has been designed by three AWS Solution Certified Architects who have a combined industry experience of 17 years. We aim to provide you with just the right depth of knowledge you need to have.

Learn the A to Z of Amazon Web Services (AWS)

## What is DynamoDB?
It is a fast and flexible NoSQL DB for applications that need consistent single-digit milliseconds at any scale. It is a fully managed database and supports both document and key-value data models.

### Dynamo DB characteristics
1. Stored on SSD
1. Spread Across three geographically distinct data centers
1. Eventual read consistency by default
1. Strongly consistent reads


**Eventual Consistent Reads**: Consistency across all copies of data is usually reached within a second. Performing a read after a short duration should return updated data.


**Strongly Consistent Reads**: A strongly consistent read returns as a result that reflects all writes that received a successful response prior to that read.
### DynamoDB pricing
1. Write throughput $0.0065 per hour for every 10 units.

1. Read throughput $0.0065 per hour for every 50 units.

1. Storage cost of $0.25 GB per month.
