Reduce latency for end-users with multi-region APIs with CloudFront

As organizations grow, they must often serve geographically dispersed users with low latency, prompting them to have a distributed global infrastructure in the cloud. In this article, we describe how to deploy global API endpoints to reduce latency for end-users while increasing an application’s availability. By using the AWS Global Network and Amazon CloudFront to deploy applications into multiple […]

Hybrid inspection architectures with AWS Local Zone

Hybrid inspection architectures with AWS Local Zones

Customers often ask about hybrid security inspection architecture patterns for latency-sensitive applications, where they want to run their workloads inside of AWS Local Zones, to perform security inspection but without compromising latency. In this post, we share some hybrid inspection architectures with traffic flows, where both workloads and security inspection appliances run inside of the […]

Implementing long-running TCP Connections within VPC networking

Many network appliances define idle connection timeout to terminate connections after an inactivity period. For example, appliances like NAT Gateway, Amazon Virtual Private Cloud (Amazon VPC) Endpoints, and Network Load Balancer (NLB) currently have a fixed idle timeout of 350 seconds. Packets sent after the idle timeout expired aren’t delivered to the destination. Some applications or […]

Analyzing stale security group rules using serverless architecture

In this blog, you will learn how to use the Lambda Function URL feature to define a AWS Lambda Function as origin for Amazon CloudFront. Lambda Function URL capability provides a dedicated HTTPS endpoint for your Lambda function deployed in an AWS Region. Function URLs are a great fit for use cases where you must […]

AWS Direct Connect monitoring and failover with Anomaly Detection

As enterprises move to the Cloud, having a reliable network connection to their on-premises data centers is fundamental. In this post, I show how to monitor your AWS Direct Connect links and initiate remediation (including automatic failover) when degradation in end-to-end path quality (packet loss, high latency) is detected. Multiple Direct Connect links at separate […]

Calculating data transfer leveraging Amazon VPC flow logs

Introduction There are several factors that contribute towards your overall costs incurred in AWS cloud. When it comes to networking, many customers ask about data transfer charges. You pay a Data Transfer charge when you send data out from AWS to Internet, between AWS Regions, or between Availability Zones (AZ). Today, there are multiple ways […]
