Implement a central ingress Application Load Balancer supporting private Amazon Elastic Kubernetes Service VPCs

Introduction Many organizations deploy Amazon Elastic Kubernetes Service (Amazon EKS) clusters into Amazon Virtual Private Cloud (VPC) environments with direct access to the internet and to other VPCs. Connectivity between the VPC hosting the Amazon EKS cluster and other VPCs is typically created using routed networking services, such as VPC Peering or AWS Transit Gateway. […]

Using AWS SSO with AWS Client VPN for authentication and authorization

AWS Client VPN  is a simple solution that allows users to connect from anywhere to their AWS environments, a capability that has become important to almost every organization over the last year. Single sign-on (SSO) is used widely across organizations of all sizes to authenticate and authorize their users’ access to enterprise applications and IT […]

Design your firewall deployment for Internet ingress traffic flows

Introduction Exposing Internet-facing applications requires careful consideration of what security controls are needed to protect against external threats and unwanted access. These security controls can vary depending on the type of application, size of the environment, operational constraints, or required inspection depth. For some scenarios, running Network Access Control Lists (NACL) and Security Groups (SG) […]

Automated VPC prefix list population for cross-Region and in-Region security group referencing

AWS customers regularly use the ability to reference another security group in the same Amazon Virtual Private Cloud (VPC), or a peered VPC in the same Region, as a dynamic reference. This ability allows customers who have highly ephemeral workloads to adopt the practice of least privilege more easily. We do not currently support security […]

Managing IP pools across VPCs and Regions using Amazon VPC IP Address Manager

Since the inception of IP networks, network engineers and operators have sought systems, solutions, and procedures to help them efficiently plan and manage IP spaces. AWS recently launched a new service named Amazon VPC IP Address Manager (IPAM) to make it easier for you to plan, track, and monitor IP addresses for your AWS workloads. […]

AWS Direct Connect monitoring and failover with Anomaly Detection

As enterprises move to the Cloud, having a reliable network connection to their on-premises data centers is fundamental. In this post, I show how to monitor your AWS Direct Connect links and initiate remediation (including automatic failover) when degradation in end-to-end path quality (packet loss, high latency) is detected. Multiple Direct Connect links at separate […]

Bring Your IPv6 Address Space to Amazon VPC IP Address Manager (IPAM)

Introduction Every device, resource, and workload connected to an Internet Protocol-based network depends on its IP address to communicate. The public and private IPv4 addressing space exhaustion, organizational mandates, and the need to provide service availability to IPv6-only clients drive an increasing number of organizations to adopt IPv6 in their environments. A well-managed IP address […]
