Uploading files to Amazon Simple Storage Service (Amazon S3) is a common requirement for modern applications. Although the concept is clear, there are several ways to implement S3 uploads, each with distinct trade-offs in security, user experience, and scalability. Understanding these patterns and their best-fit scenarios is essential for making informed architectural decisions that align […]

Imagine receiving an unexpected $1,200 Data Transfer Out (DTO) charge on your Amazon Web Services (AWS) bill. You know something generated significant outbound traffic, but you’re left wondering: which resource caused it? Where was the data sent? Was it legitimate application traffic or a security incident? This common challenge faces FinOps professionals, DevOps engineers, and […]

As organizations scale globally, balancing user experience with operational costs becomes increasingly complex. Integrating Amazon CloudFront with Application Load Balancer (ALB) addresses this challenge by reducing latency by serving content from over 750 edge locations worldwide and maintaining persistent TCP connections between CloudFront and ALB origins while reducing Data Transfer Out (DTO) expenses through the […]

Starting today, Amazon CloudFront extends its mutual TLS (mTLS) capabilities to customer origins, which enables true end-to-end authentication throughout the entire connection path—from the viewers to the customer origins. CloudFront has supported viewer mTLS between viewers and CloudFront, so that customers can strongly authenticate clients before traffic ever enters their perimeter. With this launch, that […]

Security teams managing multi-account Amazon Web Services (AWS) environments face significant operational challenges when implementing consistent access controls. Traditional approaches necessitate duplicating VPN infrastructure, managing separate bastion hosts in each account, and maintaining fragmented security policies across multiple applications. This operational overhead increases infrastructure costs and attack surfaces. This post walks you through implementing AWS […]

In this post, we examine the ability for Amazon VPC IP Address Manager (IPAM) to automate prefix lists updates with prefix list resolver. This new feature uses the IPAM database to generate groups of IP addresses based on connectivity requirements and automates connectivity configurations by propagating IP addresses to Amazon Web Services (AWS) resources, such […]

It’s 2 AM when your phone alerts you to failing customer transactions in the North Virginia Region. As a network operator managing an Imaging platform on Amazon Web Services (AWS), you’re faced with troubleshooting an architecture that spans multiple Amazon Virtual Private Cloud (Amazon VPC), uses AWS Transit Gateway for interconnectivity, and runs many microservices. […]

Geo-restriction is a critical security control for blocking traffic from high-risk regions. Learn how to implement geographic filtering using Amazon CloudFront, Route 53, AWS WAF, and AWS Network Firewall—and discover when to use each service for your specific architecture needs.

In this post, we demonstrate how to distribute Amazon VPC IP Address Manager (IPAM) costs from the IPAM owner account to the member accounts in AWS Organizations and implement chargeback. We walk through analyzing IPAM usage in AWS Cost Explorer from both member and management accounts. Furthermore, we cover key considerations and best practices for communication and […]
