Networking best practices for generative AI on AWS
Introduction As generative artificial intelligence (generative AI) continues to evolve, the demand for more powerful and efficient computing resources grows, along with the need to manage exponentially increasing amounts of data. Datasets used for training generative AI models are typically measured in terabytes (TB), orders of magnitude bigger than traditional machine learning (ML) datasets whose […]
How to identify website performance bottlenecks by measuring time to first byte latency and using Server-Timing header
While website performance issues are a common occurrence, pinpointing their root causes can be a challenging task. In this post, you will learn how to simplify the performance troubleshooting process by unlocking the potential of the Server-Timing header. This header allows backend components to communicate timing metrics and other insights relevant to performance monitoring in […]
Tenant routing strategies for SaaS applications on AWS
[Update on May 7th 2025] Amazon CloudFront SaaS Manager introduces a new type of distribution called a multi-tenant distribution. A key challenge for SaaS providers is designing secure, scalable tenant routing mechanisms to identify tenants and route requests to appropriate resources. Effective tenant routing ensures isolation, scalability, and security. This post explores strategies for routing […]
Simplify global security inspection with AWS Cloud WAN Service Insertion
AWS Cloud WAN is a managed wide-area networking (WAN) service that you can use to build and operate wide area networks that connect your data centers and branch offices, as well as your Amazon Virtual Private Cloud (Amazon VPC) VPCs. You can use network policies to centrally configure and automate network management and security tasks, […]
Scaling strategies for Elastic Load Balancing
Elastic Load Balancing (ELB) offers four types of load balancers, all featuring high availability, automatic scaling, and robust security support for your applications: Application Load Balancer (ALB), Network Load Balancer (NLB), Gateway Load Balancer (GWLB), and Classic Load Balancer (CLB). ELB automatically scales up and down, and scales in and out in response to traffic […]
Using latency-based routing with Amazon CloudFront for a multi-Region active-active architecture
An update was made on April 11th, 2024, outlining deployment procedure. This post guides you through setting up the networking layer for a multi-Region active-active application architecture on AWS using latency-based routing in Amazon Route 53 with Amazon CloudFront to deliver a low-latency, reliable experience for your users. Building active-active architectures using AWS networking services improves […]
Use VPC IP Address Manager to manage subnet CIDRs
Amazon VPC IP Address Manager (IPAM) is a VPC feature that allows you to plan, track, and monitor IP addresses for your AWS workloads. Until now, VPC IPAM allowed you to allocate CIDR blocks and monitor them at the VPC level. With a recent feature enhancement in VPC IPAM, you can now manage CIDR allocations […]
Using VPC Reachability Analyzer to discover network paths across multiple AWS Regions
Amazon Web Services (AWS) customers can use the AWS global infrastructure to deploy workloads to multiple AWS Regions. They can create global networks that span multiple AWS Regions to connect these workloads to each other and to on-premises networks. A common design pattern is to use a central networking AWS account to own shared network resources, such as AWS Transit […]
AWS Verified Access Integration with AWS IAM Identity Center and SAML 2.0 Identity Providers
In this blog post, we will discuss how you can setup VPN-less secure access to your corporate applications if you are using Security Assertion Markup Language (SAML) based identity providers (IdPs). We will also provide guidance if you have already invested in integrating third-party IdPs with AWS IAM Identity Center (successor to AWS Single Sign-On), […]
Achieve optimal routing with AWS Cloud WAN for multi-Region networks
In multi-Region AWS Cloud WAN deployments, customers deploy centralized architectures for use cases such as traffic inspection, hybrid connectivity (using AWS Transit Gateways and AWS Direct Connect), and internet egress. For internet egress, you may use a single egress VPC per AWS Region or per geography (collection of AWS Regions), for example, Americas (AMER GEO), […]
