Since a few days, Amazon provides a native way to enable Auto Scaling for DynamoDB tables! Luckily the settings can be configured using CloudFormation templates, and so I wrote a plugin for serverless to easily configure Auto Scaling without having to write the whole CloudFormation configuration.
You can find the serverless-dynamodb-autoscaling on GitHub and NPM as well. Just install it using npm or yarn and add it to our serverless.yml configuration:
plugins:
- serverless-dynamodb-autoscaling
custom:
capacities:
- table: CustomTable # DynamoDB resource name
read:
minimum: 5 # Minimum read capacity
maximum: 1000 # Maximum read capacity
usage: 0.75 # Usage percentage
write:
minimum: 40
maximum: 200
usage: 0.5
After your next deployment, Amazon will configure native Auto Scaling for your DynamoDB table. Before the native support from Amazon, you had to handle Auto Scaling on your own, with a custom AWS Lambda function for example. But those times a finally over!

The YubiKey is a great OpenGPG smart card compatible hardware device. I use my YubiKey to store my private GnuPG key and for authenticating SSH connections. A few applications, however, don’t work with the OpenGPG card and require a file containing the key per default; Sequel Pro is one of them.

AWS Lambda functions together with an Amazon Kinesis Stream offer a great way to process continuous information. I created an example project called Serverless Analytics to demonstrate this. You can use this as the starting point to create your very own Google Analytics clone and run it serverless and hopefully maintenance-free on Amazon.

When you use a serverless environment for your service (and you should!), chances are high you might be using the Serverless framework and may end up in a situation like me with the need to process the AWS CloudFormation Stack Output after deploying the service.

Have you ever wondered how to process messages from SQS without maintaining infrastructure? Amazon Web Services perfectly support SNS as a trigger for AWS Lambda functions, but with SQS you have to find a custom solution. This tutorial will show an experimental setup using Serverless to read messages from an SQS queue and build auto-scaling worker processes.
