DynamoDB is a beautiful piece of technology. This course covers it in depth. You will learn what DynamoDB is, what it can do, and how to use it. You will learn about table creation and go into the details of security and monitoring. Additionally, you will learn how to manage access control in DynamoDB and how to monitor the usage. 

After taking this course you will become confident in using DynamoDB and will have the know-how to avoid those rookie mistakes that people make while using this technology. No matter how familiar you are with AWS technologies, this course has something for you. For the beginner, this course gives a nice flavor of AWS technologies. And for advanced practitioners, this course provides a definitive guide to DynamoDB and related technologies.

DynamoDB Deep Dive: NoSQL for Software Engineers

As was discussed earlier in the "Salient Features of DynamoDB" lesson we are charged for the frequency of our reads and writes, instead of for the storage we use. We can choose one of the two following options for running our table:

1. **On-demand provisioning**: In this provisioning, AWS will scale our provision capacity up or down based on our usage. We do not have to define our throughput units.
2. **Provisioned capacity**: In this option, we specify upfront how much capacity, based on our estimated reads and writes per second, we will use. 

We will discuss the calculation behind the capacity unit next.

## Write capacity
One write capacity unit means DynamoDB will support one write per second for an item sized at 1KB. If the item size is greater than 1KB, say 10KB, it will need more capacity units, i.e. in this case, it will need 10 capacity units. For strong consistency in writes, we will need two write capacity units to write an item sized at 1 KB in one second.

Let's look at a calculator to understand this better.
