Introducing Amazon VPC Flow Logs to Kinesis Data Firehose

Amazon Virtual Private Cloud (Amazon VPC) Flow Logs helps you understand network traffic patterns on AWS by providing network telemetry data about the IP traffic flowing to and from ENIs in your VPC. It lets you perform numerous analytics tasks, such as diagnosing overly restrictive security group rules, monitoring traffic that is reaching an instance, […]

Design patterns for interconnecting a telco data center to an Amazon VPC

Traditionally, communication service providers (CSPs) in the telecom industry have used a Virtual Routing and Forwarding (VRF) technique to segregate their data center (DC) networks per each network domains; for examples of domain such as Operation, Administration & Management (OAM), signaling, roaming, and user traffic networks. Each VRF domain in the data center must also […]

AWS Cloud WAN and Amazon VPC IPAM with AWS Control Tower

AWS Control Tower offers a straightforward way to set up and govern a multi-account AWS environment, following prescriptive best practices to build a secure landing zone quickly. You can provision tens, if not hundreds, of new AWS accounts at one time using AWS Control Tower. Once you provision accounts, you typically require the deployment of Amazon […]

Dual-stack IPv6 architectures for AWS and hybrid networks – Part 2

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 […]

Introducing IPv6-only subnets and EC2 instances

In June 2021, we announced our continued commitment and innovation towards the enablement of IPv6 on AWS. Today, we take a monumental step forward with the ability to create an IPv6-only architecture on AWS. With this launch, Amazon Virtual Private Cloud (VPC) now allows you to create IPv6-only subnets in your dual-stack VPCs and launch […]

Introduction to Traffic Mirroring to GWLB Endpoints as Target

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 […]

Analyze Network Traffic of Amazon Virtual Private Cloud (VPC) by CIDR blocks

This post was co-written by Abhijit Rajeshirke, Solutions Architect at AWS; Charu Singh, Software Development Engineer at AWS; and Hooman Rashedi, Principal Solution Architect at Presidio AWS enterprise customers are using hundreds of accounts and Amazon Virtual Private Cloud (Amazon VPC) to segment their workloads and expand their footprint. This level of scale can lead […]

Collecting AWS networking information in large multi-account environments

Many organizations need to review or audit networking information within AWS environments that contain multiple AWS accounts. At scale, questions such as “which accounts have Internet access enabled?”, “which account owns the Elastic IP 198.51.100.101?” and, “what are the IP addresses of my NAT gateways?” can be challenging to answer. Traditionally, within an individual account, […]
