Seamless EC2 monitoring with the Unified CloudWatch Agent

Review: Amazon Aurora Serverless - A cloud-native and production-ready relational database?
It was never easier to scale your compute layer. EC2 Auto Scaling, Fargate, and Lambda enable horizontal scaling. But how do you scale your database? Use a NoSQL database like DynamoDB, one could say. But what if you don’t want to miss all the advantage...Read more

Andreas & Michael Wittig
We are independent consultants, technical writers, and programming founders. All these activities have to do with AWS. And by the way, we are brothers too.
In 2009, we joined the same company as software developers. Three years later, we were looking for a way to deploy our software—an online banking platform—in an agile way. We got excited about the possibilities in the cloud and the DevOps movement. It’s no wonder we ended up migrating the whole infrastructure of Tullius Walden Bank to AWS. This was a first in the finance industry, at least in Germany! Since 2015, we have accelerated the cloud journeys of startups, mid-sized companies, and enterprises. We have penned books like Amazon Web Services in Action and Rapid Docker on AWS, we regularly update our blog, and we are contributing to the Open Source community. Besides running a 2-headed consultancy, we are entrepreneurs building Software-as-a-Service products.
We are available for projects.
