Analyzing stale security group rules using serverless architecture

Security is a top priority for AWS and customers running workloads in AWS. The previous post Top 10 security items to improve in your AWS account, covered the top security items that AWS customers should pay special attention to if they want to improve their security posture. High on the list is the need to […]

Architect dual stack Amazon VPC with multiple IPv6 CIDR blocks

Introduction With the increasing adoption of IPv6 on AWS, the need to create an easy-to-manage, hierarchical, and scalable IP addressing plan for Amazon Virtual Private Clouds (Amazon VPCs) becomes critical for customers. With IPv4, adding more CIDR blocks to a VPC was driven mainly by the need to increase the address space within a VPC. […]

Designing hyperscale Amazon VPC networks

Introduction Amazon Web Services (AWS) customers are continuously increasing the number of applications and workloads they run on AWS, driven by accelerated cloud adoption and environment expansion. An environment can be considered “Hyperscale” once it supports thousands of application endpoints and tens or hundreds of gigabits of traffic per second. Hyperscale environments on AWS favor […]

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 […]

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 […]
