Improving Performance on AWS and Hybrid Networks

In this post, we provide recommendations to improve network performance on AWS and hybrid networks. In today’s enterprise networking environment, it is becoming common for customers to have multi-gigabit connectivity to AWS either through AWS Direct Connect or over the Internet. Although network bandwidth is fundamental, several other factors come into play for network performance, […]

External Connectivity to Amazon VPC Lattice

In this blog post, we discuss how to connect on-premises and external services to Amazon VPC Lattice. We will go over architectural considerations and requirements for connecting services from trusted locations (on-premises), non-trusted locations (3rd party), and across AWS Regions. Then, we provide a solution that builds out a capability to facilitate this using AWS […]

Hybrid security inspection architectures with AWS Cloud WAN and AWS Direct Connect

AWS Cloud WAN makes it easy to build and operate wide area networks that connect your data centers and branch offices, as well as your Amazon Virtual Private Clouds (VPCs). With Cloud WAN, you connect to AWS through your choice of local network providers, then use a central dashboard and network policies to create a […]

Best practices and considerations to migrate from VPC Peering to AWS Transit Gateway

This post presents recommendations and best practices when migrating your existing VPCs from Amazon Virtual Private Cloud (VPC) Peering to AWS Transit Gateway. It includes a migration walkthrough and considerations that you can address to improve your odds of a seamless migration. This post also details common networking testing and bench-marking tools such as iPerf […]

Connecting VPCs securely and at scale

Connecting VPCs securely and at scale to 3rd party public services in on-premises networks

There are many things to consider when connecting your Amazon Virtual Private Clouds (Amazon VPCs) to third-party applications running in data centers outside AWS. You need connections that are secure and scalable, especially when the third-party vendor uses a multi-tenant architecture. With multi-tenant services, where they have many of their customers sharing the same system, […]

Inspecting network traffic between Amazon VPCs with AWS Cloud WAN

AWS Cloud WAN is a managed service used to build wide area networks that connect data centers, branch offices, and Amazon Virtual Private Clouds (VPCs) using AWS global infrastructure. When building with Cloud WAN, many organizations employ next-generation firewalls (NGFW) and intrusion prevention systems (IPS) to inspect network traffic as part of a defense-in-depth strategy. […]

Build secure multi-account multi-VPC connectivity for your applications with Amazon VPC Lattice

Introduction In this blog post, we will discuss how you can use Amazon VPC Lattice to connect your services securely, and monitor communication flows, in a simple and consistent way across instances, containers, and serverless, in a multi-account and multi-Virtual Private Cloud (VPC) environment. We’ll define the new constructs VPC Lattice leverages to enable application […]

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 […]

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 […]

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 […]
