Protect Amazon Route 53 domains during account lifecycle events: Best practices for domain governance in multi-account organizations
Domain governance in Amazon Route 53 can mean the difference between a routine account decommissioning and an unplanned outage. Picture this situation: your organization closes an Amazon Web Services (AWS) account, and five days later a customer-facing website becomes unreachable, email stops flowing, and SSL certificate validation fails. A domain that this account had registered […]
Selecting the right AWS private connectivity options: A decision framework
Selecting the right AWS private connectivity option is harder than it used to be. The choices now span AWS Direct Connect, AWS Direct Connect SiteLink, and AWS Interconnect (last mile and multicloud). Picking the wrong option can lead to over-provisioning, slow time to market, or rework. In this post, we present a decision framework for […]
Prevent VPN traffic leaks with Client VPN Route Enforcement in AWS Client VPN
Unintended traffic leaks are a real risk when you rely on remote connectivity to access cloud resources, so maintaining VPN routing integrity on connected devices is essential. When a device connects through a VPN, the administrator-defined routes instruct the operating system to direct specific traffic through the encrypted tunnel. However, those routes can be altered […]
VPC resource gateways: Implementation patterns and use cases
When you need to connect applications across Amazon Virtual Private Clouds (Amazon VPCs) to services that don’t fit the traditional AWS PrivateLink provider-consumer model, you face complex networking challenges that VPC peering and AWS Transit Gateway alone can’t easily solve. This is especially true for overlapping IP spaces. You can now connect to services that […]
Extending SD-WAN Segmentation into AWS Cloud WAN – Part 2
For organizations operating multi-tenant environments, regulated environments, or multiple business units, maintaining strict network segmentation between SD-WAN and AWS is essential for meeting security, compliance, and operational requirements. This is Part 2 of the two-part series on extending SD-WAN segmentation into AWS Cloud WAN. In Part 1, the Generic Routing Encapsulation (GRE) based Connect attachment […]
Extending SD-WAN Segmentation into AWS Cloud WAN – Part 1
For organizations operating multi-tenant environments, regulated environments, or multiple business units, maintaining strict network segmentation between SD-WAN and AWS is essential for meeting security, compliance, and operational requirements. Deploying SD-WAN virtual appliances and extending your segmentation through AWS Cloud WAN helps unify these segmented environments under a single, scalable global network. That said, segmentation is […]
Best practices for securing your IPv6 infrastructure on AWS using VPC Block Public Access
Organizations often struggle with how to secure IPv6 network and application infrastructure on AWS based on what type of IPv6 addresses they are using. In this post, I cover the best practices and considerations for securing private IPv6 resources while maintaining the flexibility to adjust connectivity models as your infrastructure evolves. I also cover how […]
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 […]
Best Practices for TCP Connection Management on EC2
With sixth-generation Nitro (Nitro V6) instances, launched in June 2025, the default TCP connection tracking idle timeout changed from 432,000 seconds (5 days) to 350 seconds. Applications that hold idle connections open for long periods, such as database connection pools, Internet of Things (IoT) telemetry, and persistent microservice connections, may experience unexpected connection drops after […]
Manage caches with precision using Amazon CloudFront Invalidation by Cache Tag
Today, Amazon CloudFront is launching Invalidation by Cache Tag, a new capability that transforms how developers manage cached content. With this feature, you can invalidate groups of related cached objects using a single invalidation request, regardless of URL structure—making cache management more precise, efficient, and developer-friendly. In this post, we discuss the benefits of this […]
