Introducing the LBC Ingress-to-Gateway API migration toolkit

Migrating your AWS Load Balancer Controller (LBC) Ingress resources to the Gateway API by hand is tedious and error prone. You need to rewrite annotations, path rules, and TLS configuration, and a mistake can disrupt the production traffic. The Ingress-to-Gateway API migration toolkit for LBC removes that risk by giving you a guided, validated path […]

Setting up Layer 2 Networking on Amazon EC2

Some workloads are strong candidates for moving to the Amazon Elastic Compute Cloud (Amazon EC2) but depend on Layer 2 (L2) network communication, which Amazon Virtual Private Cloud (Amazon VPC) doesn’t natively support. With the right approach, you can run these workloads on AWS. Layer 2 requirements appear in a few ways. Industrial control systems […]

Private AI agent with WebSocket streaming over CloudFront VPC Origins and the next generation of OpenSearch Serverless for knowledge retrieval

Reviewing partner contracts by hand is slow and repetitive, so teams want an AI agent to do the first pass. In the example used throughout this post, a company called Example Corp reviews incoming partner agreements against its own standard operating procedures. A partner uploads an agreement, the agent checks it against those procedures, and […]

Automating CIDR expansion: Reducing IP exhaustion downtime

Automating CIDR expansion: Reducing IP exhaustion downtime

Learn how to build a serverless automation that monitors VPC IP utilization and expands CIDR capacity within minutes. This solution uses AWS Lambda, Step Functions, and IPAM to detect IP exhaustion risk and add secondary CIDRs with new subnets automatically. Three operating modes support environments with full IPAM management, IPAM for subnets only, or no IPAM at all. Deploy with a single SAM command and configure through VPC tags.

Intelligent failover using AWS Lambda@Edge and Amazon DynamoDB

Modern applications increasingly require seamless user experiences and high availability, especially in scenarios where regional disruptions or outages could impact critical workloads. Businesses frequently face challenges when dynamically allocating users to specific endpoints or regions while providing persistent user-endpoint relationships and implementing robust failover mechanisms. To address these complex scenarios, this post describes a solution […]

Extending NLB health checks for RADIUS using an Amazon ECS witness

Extending NLB health checks for RADIUS using an Amazon ECS witness

Network Load Balancer health checks confirm that a RADIUS server is reachable, not that it can authenticate a user, so a server with a failed identity store keeps receiving traffic. This post walks through an open-source reference solution that closes the gap with a single Amazon ECS witness that runs application-layer RADIUS probes and reconciles NLB target group membership directly.

Private connectivity patterns for Amazon Bedrock AgentCore Gateway Targets

Private connectivity patterns for Amazon Bedrock AgentCore Gateway Targets

Private connectivity from AgentCore Gateway to your targets reduces compliance scope and simplifies auditing making it a common requirement in regulated environments. Whether your targets run inside an Amazon Virtual Private Cloud (Amazon VPC), across AWS accounts, in other AWS Regions, on-premises, or in multicloud environments, you need connectivity patterns that keep traffic off the public internet […]

Uplynk’s Resilient Multi-Region Video Streaming with Amazon Route 53

Uplynk’s resilient multi-Region video streaming with Amazon Route 53 demonstrates how media companies can solve one of their most critical challenges: keeping millions of concurrent streams running when an entire AWS Region becomes unavailable. For video streaming providers, Regional outages create immediate business impact – each second of downtime means lost subscribers, abandoned sessions, and […]

Nginx Ingress Migration

Navigating the NGINX Ingress retirement: A practical guide to migration on AWS

The Kubernetes SIG Network and Security Response Committee has announced that Ingress NGINX will be retired in March 2026. If your organization runs workloads on Kubernetes — whether on Amazon Elastic Kubernetes Service (Amazon EKS), self-managed clusters on EC2, or hybrid environments — this upcoming change requires immediate planning and attention. This change impacts approximately […]
