Centralizing outbound Internet traffic for dual stack IPv4 and IPv6 VPCs

Organizations have been adopting IPv6 in their IPv4 environments to solve IP address exhaustion or meet compliance requirements. Since IPv6 isn’t backward compatible with IPv4, several mechanisms can facilitate communication between hosts that support one or both protocols. One common way is by using dual stack deployments. For architectures where dual stack deployments aren’t the […]

AWS Direct Connect and AWS Local Zones interoperability patterns

AWS Direct Connect and AWS Local Zones interoperability patterns

In December 2019, we announced our first Local Zone in Los Angeles. As a refresher, AWS Local Zones are a type of infrastructure deployment that place compute, storage, database, and other AWS services close to large population, industry, and IT locations. Local Zones extend the capabilities of an AWS Region – what we called “parent” […]

Achieving traffic segmentation in multi-AWS Region environments using AWS Transit Gateway and AWS Cloud WAN

In June 2022, we announced AWS Cloud WAN in general availability, a managed wide area networking (WAN) service that makes it easy for you to build, manage, and monitor a global network connecting your resources across your AWS Regions and on-premises environments. With Cloud WAN, you have a central place to create and manage your […]

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 […]

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 […]

Migrating accounts between AWS Organizations from a network perspective

In this post, we’ll discuss the considerations, recommendations, and approach for migrating AWS accounts between AWS Organizations from a networking perspective. We’ll explain the behavior of AWS networking resources when AWS accounts are moved between Organizations. We’ll also analyze the behavior from different viewpoints including service availability, management and governance, as well as commercial and operations. […]

Introducing VPC Flow Logs for AWS Transit Gateway

Since the launch of Amazon Virtual Private Cloud (Amazon VPC) Flow Logs in 2015, customers have utilized VPC Flow Logs to gain better visibility of network traffic patterns on AWS by providing network telemetry data regarding the IP traffic flowing to and from ENIs within a given VPC. As customers’ networks grew, customers began utilizing […]

AWS Cloud WAN and AWS Transit Gateway migration and interoperability patterns

Introduction At AWS re:Invent 2021, we launched a public preview of AWS Cloud WAN, a managed service for creating a global network using AWS global network infrastructure. Cloud WAN makes it easy to build and operate global wide area networks (WAN) to connect your data centers, branch offices, and Amazon Virtual Private Clouds (VPCs). Cloud […]

How Repsol manages and monitors their AWS network with dashboards, alarms and automation

Large enterprises often deploy workloads on Amazon Web Services (AWS) using multiple accounts. This helps isolate workloads, manage permissions more easily, and simplifies cost allocation. However, managing a multi-account environment can make your network topology more complex and requires additional monitoring and automation. At Repsol, a global multi-energy company present throughout the entire value chain, […]

Running multicast-enabled containers on AWS

Introduction Multicast is a popular IP-based communication mechanism that is actively employed in many industry verticals, including finance, media, telco, transportation, and others. This post describes how to enable multicast in container environments orchestrated by Amazon Elastic Container Service (ECS). Although Amazon ECS is a fully managed container orchestration service, some additional steps must be […]
