VPC Routing Enhancements and GWLB Deployment Patterns

At re:Invent 2020, AWS introduced  Gateway Load Balancer (GWLB), an AWS service that helps you deploy, scale, and manage third-party virtual network appliances, such as firewalls, intrusion detection and prevention systems, and others. GWLB is a type of load balancer under the Elastic Load Balancing (ELB) family. Other load balancers within the ELB family include […]

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 […]

Monitoring EC2 Connection Tracking utilization using a new network performance metric

In 2020, Amazon Elastic Compute Cloud (Amazon EC2) announced new network performance metrics for EC2 instances made available using ENA driver and Amazon CloudWatch agent. We covered the launch in this post. These network performance metrics give customers visibility into the number of packets queued or dropped when an instance’s networking allowances, such as Network […]

Introducing multi-function packager, allowing more than one function per event trigger on Amazon CloudFront

AWS Network Optimization Tips

When thinking about architecture, it’s very common to come across scenarios where there is no right or wrong answer – the best answer is “it depends”. You must carefully consider the tradeoffs between cost, performance, reliability, and operational efficiency before coming to a decision. A little planning ahead of time can help you avoid numerous […]

Improving video observability with CMCD and CloudFront

Observability is critical for operating any system. It should tell whether the system is functioning correctly, provide insights in user experience, notify when issues occur, and help to locate the root cause. However, building an observable video streaming system can be a challenge for customers as it requires collecting, correlating, and analyzing data from several […]

External Server Authorization with Lambda@Edge

Introduction In this blog post, we will explain how you can use Lambda@Edge to authorize requests to Amazon CloudFront by forwarding authorization data to external authorization servers. We will outline the sequence of requests in such a workflow, the steps for implementation with Node.js sample code, and a CloudFormation template for a simple external test […]

AWS Site-to-Site VPN, choosing the right options to optimize performance

AWS Site-to-Site VPN is a fully-managed performant, scalable, secure, and highly-available way to connect your on-premises users and workloads to AWS. When using Site-to-Site VPN you can connect to both Amazon Virtual Private Clouds (Amazon VPCs) with two tunnels per connection for increased redundancy. For even greater performance with sites further from your AWS Region(s), […]

How to use AWS Network Manager to visualize Transit Gateways across multiple accounts in the AWS Organization

When you migrate or build a new applications in AWS, you must connect multiple Amazon Virtual Private Clouds (Amazon VPCs) spread across different accounts and your on-premises systems with these VPCs.
