Building production-ready DNS infrastructure with AWS CDK
DNS outages have immediate and severe ripple effects on enterprise infrastructure, yet many Amazon Web Services (AWS) organizations still manage Amazon Route 53 configurations manually instead of using infrastructure as code (IaC) tools such as AWS Cloud Development Kit (AWS CDK). Consider a common scenario: an engineer accidentally deletes a critical DNS record while troubleshooting. […]
Target Group Load Shedding for Application Load Balancer
Load Shedding Load shedding is the practice of sacrificing enough application traffic to keep partial availability in the presence of an overload condition. Used in conjunction with strategies like load balancing, load shedding helps applications support service level agreements (SLAs) when increased traffic overwhelms available system resources. While the cloud’s elasticity reduces the need for […]
Building an egress VPC with AWS Transit Gateway and the AWS CDK

Further simplification can be achieved by routing all outbound traffic through one shared egress VPC. This allows re-use of NAT Gateways and can improve overall network design and operational efficiency. This ‘egress VPC’ design pattern is […]
