We are two brothers focusing 100% on Amazon Web Services (AWS). Every other week, one of us prepares the topic of the podcast. The topic is not known to the other one, which results in surprising conversations about all things AWS.
Typically, we are covering the following topics: DevOps, Serverless, Container, Security, Infrastructure as Code, Container, Continuous Deployment, S3, EC2, RDS, VPC, IAM, VPC, and many more.

Amazon Web Services in Action 3rd Edition out now!
We are happy to announce the official launch of our new book Amazon Web Services in Action 3rd Edition. The 3rd edition contains a new chapter covering containers on AWS: Building modern architectures for the cloud: ECS, Fargate, and App Runner. The chapter starts with the simplest way to deploy containers on AWS: App Runner. After that, we dive into our favorite architecture consisting of ECS to orchestrate containers and Fargate providing a Serverless container infrastructure.
Besides adding a new chapter, we have entirely rewritten chapter 15: Automating deployment: CodeDeploy, CloudFormation, and Packer. Automating the deployments is key to success in the cloud. Therefore, chapter 15 introduces three different options:
CodeDeploy to roll out new versions of an application among a fleet of EC2 instances.
Packer to bundle the latest version of an application into an AMI.
CloudFormation to orchestrate rolling updates of EC2 instances managed by an auto-scaling group.
