As you deploy AI agents into production, establishing secure network connectivity becomes a critical design decision: how do users connect to agents, how do agents connect to other agents, and how do agents reach private resources? Amazon Bedrock AgentCore Runtime provides flexible network connectivity options that let your AI agents securely connect to public and […]

Introduction AWS Site-to-Site (S2S) VPN is a fully managed service that enables you to establish secure connections between your on-premises networks and AWS using IP Security (IPSec) tunnels. When configuring these connections AWS Site-to-Site (S2S) VPN offers two routing options: static and dynamic routing with Border Gateway Protocol (BGP). While static routing offers simplicity for […]

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. […]

As organizations scale their AWS environments across multiple accounts and Amazon virtual private clouds (VPCs), controlling internet access to cloud resources becomes challenging. With multiple accounts and network paths, maintaining secure network boundaries becomes a priority. A common security pattern is the demilitarized zone (DMZ) architecture, which isolates public-facing services from internal networks to reduce […]

Update (May 2026): Amazon CloudFront now natively supports tag-based cache invalidation — no additional infrastructure required. You can tag cached objects via origin response headers or S3 metadata and invalidate them by tag directly through the CloudFront API. For details, see the CloudFront Developer Guide and the launch blog post. If you are starting fresh, […]

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 […]

Introduction This post is intended for networking engineers and architects evaluating AWS VPN options (200-level content). It assumes familiarity with basic AWS networking concepts such as virtual private clouds (VPCs), virtual private gateways (VGWs), and transit gateways (TGWs). If you are new to AWS VPN, the AWS VPN User Guide provides foundational context. Organizations implementing […]

In Part 1 of this series, we demonstrated a scalable solution of using Amazon Web Services Identity and Access Management (AWS IAM) conditional keys and AWS principal tags for fine-grained access control of shared Amazon Route 53 hosted zones, public or private, in the same AWS account. As user environments grow, AWS administrators and network […]

AWS Client VPN now supports native attachment to AWS Transit Gateway, eliminating the need for a dedicated hosting VPC. This post walks through how to configure the integration, preserve source IP addresses end-to-end without SNAT, and centralize remote access across multiple VPCs and on-premises networks in a multi-account architecture.
