Introduction DNS name resolution is a fundamental part of all on-premises and cloud networks. For customers with hybrid networks, additional infrastructure and configuration are needed for private DNS resolution to work seamlessly across environments. However, building this type of DNS infrastructure in a multi-account environment is complex. In this post, we show how to automate […]

AWS Direct Connect (DX) recently launched support for virtual interface (VIF) metrics in Amazon CloudWatch. With this new enhancement, CloudWatch can now track metrics at the DX VIF level and provide greater insight into utilization. You can set up alarms based on metrics and trigger actions to remediate problems. I’ve heard from many customers that […]

Introduction Authenticating users to applications and services on the web and at scale can be challenging. Having a separate set of credentials for each application is not an efficient approach. It is difficult to manage for IT departments and doesn’t provide a good experience for users. A common way to solve this challenge is to use […]

Update: We’ve updated this blog and the AWS Lambda function code to work with both “custom” and “s3” style origins in Amazon CloudFront. Previously, only “custom” types were covered. In August 2022, CloudFront launched OAC (Origin Access Control), providing native support for customers to use CloudFront to access S3 bucket encrypted with SSE-KMS. Depending on […]

AWS gives you the ability to extend existing on-premises remote access VPN solutions to the cloud. This not only allows access to resources within AWS, but using hybrid connectivity, also to on-premises resources. VPN clients use AWS internet connectivity as an entry point, and the flexibility of Amazon EC2 to scale capacity behind remote access […]

Introduction Capturing and querying Amazon EKS and Kubernetes (K8s) cluster traffic is an important skill to possess. It is especially useful during incident-response and when troubleshooting networking issues surrounding nodes, pods, or services in your cluster. Amazon makes it easier to perform capture and query tasks with Amazon VPC Flow Logs and Amazon Athena. Administrators can use Amazon VPC Flow Logs to […]

Traditional on-premises VPN services are fixed in capacity and difficult to scale up, or down, in a rapid and on-demand fashion. Hardware constraints, licensing, and bandwidth can all be factors that prevent traditional client VPN services from scaling to meet the needs of a rapidly growing mobile workforce. Fortunately, the elasticity of cloud and pay-as-you-go […]

You can now enable multi-factor authentication (MFA) for users connecting to an AWS Client VPN endpoint. This solution is ideal for organizations that want additional security when remote users are accessing AWS or on-premises resources. MFA improves the authentication process by requiring more than a user name, password, and certificate (the first factor). MFA requires […]
