When I meet with customers and discuss AWS Gateway Load Balancer (GWLB), I often get asked for suggestions regarding integrating it with their existing Linux appliances. GWLB utilizes GENEVE encapsulation with some important custom metadata, which doesn’t natively work with either Linux or Linux’s GENEVE module (which is designed only for Ethernet (Layer 2) packets, […]

In part one of our series on IPv6 for AWS and hybrid network architectures, we explored some of the most common dual stack designs: dual stack Amazon Virtual Private Cloud (Amazon VPC) and Amazon Elastic Compute Cloud (Amazon EC2) instances, Internet connectivity, Internet-facing Network Load Balancer and Application Load Balancer deployments, as well as VPC […]

Network architects need the ability to gain insights into real-time traffic between different resources within their VPCs. Since the announcement of VPC Traffic Mirroring in 2019, the VPC feature has provided this by copying network traffic from elastic networking interfaces (ENIs) on customer’s instances as source, and then sending the traffic to a destination target […]

Happy 2022 AWS Networking & Content Delivery enthusiasts! In December 2021, AWS hosted its 10th annual re:Invent conference. The Networking & Content Delivery team had 14 unique breakout sessions that were recorded and can be found on this playlist. In addition to these sessions, the Networking team had a leadership session presented by David Brown, […]

Introduction Many organizations deploy Amazon Elastic Kubernetes Service (Amazon EKS) clusters into Amazon Virtual Private Cloud (VPC) environments with direct access to the internet and to other VPCs. Connectivity between the VPC hosting the Amazon EKS cluster and other VPCs is typically created using routed networking services, such as VPC Peering or AWS Transit Gateway. […]

Introduction Exposing Internet-facing applications requires careful consideration of what security controls are needed to protect against external threats and unwanted access. These security controls can vary depending on the type of application, size of the environment, operational constraints, or required inspection depth. For some scenarios, running Network Access Control Lists (NACL) and Security Groups (SG) […]

Load Shedding Load shedding is the practice of sacrificing enough application traffic to keep partial availability in the presence of an overload condition. Used in conjunction with strategies like load balancing, load shedding helps applications support service level agreements (SLAs) when increased traffic overwhelms available system resources. While the cloud’s elasticity reduces the need for […]

(April 25, 2024) Clarification – AWS PrivateLink does not currently support UDP.   Application Load Balancer (ALB) is a fully managed layer 7 load balancing service that load balances incoming traffic across multiple targets, such as Amazon EC2 instances. ALB supports advanced request routing features based on parameters like HTTP headers and methods, query string, […]

The Gateway Load Balancer (GWLB) service launched with support from the partner network. These partners provide networking appliances that enable customers to perform varying levels of packet inspection on flows that pass through them, taking action as necessary and as defined within their configuration. For a list of partners that support GWLB, refer to the […]

Update: As of January 27, 2022, AWS PrivateLink publishes data points to Amazon CloudWatch for your interface endpoints, Gateway Load Balancer endpoints, and endpoint services. CloudWatch enables you to retrieve statistics about those data points as an ordered set of time series data, known as metrics. As a PrivateLink Endpoint owner, you can use metrics […]
