As I work with more and more clients the use cases for DynamoDB continue to rise. I wanted to put together a quick how to article.
Why DynamoDB?
Solid performance
Can scale
It is not a relational database
It is a fully managed DB that is replicated across 3 x AZs providing HA
Low cost
Integrated with IAM for authorization, admin, and security.
How to configure a DynamoDB
create
Here is where you want to give a name to the table and also provide a name for the primary partition key
You can uncheck the use default settings button for more customization
I’m switching to provisioned so it is free-tier eligible
These boxes are greyed out because auto scaling has been setup
AWS even builds in a nice calculator for calculating cost
My example: size of 8kb, 20 reads per second and want 40 writes per second
Here is where you can change the thresholds for scaling up and down
Create and now we are done
Give it a minute and now your DynamoDB is created
Items > create item
Insert some data then save
Everything looks good
Summary:
As you can see setting up a basic DynamoDB is very easy and simple if you already have a plan in place. As always, I hope y’all found this useful.
