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 Site-to-Site VPN is a fully-managed performant, scalable, secure, and highly-available way to connect your on-premises users and workloads to AWS. When using Site-to-Site VPN you can connect to both HAQM Virtual Private Clouds (HAQM VPCs) with two tunnels per connection for increased redundancy. For even greater performance with sites further from your AWS Region(s), […]

This blog is co-authored by Parrish Gamarra, Principal Network Architect, Johnson & Johnson Introduction Mergers, Acquisitions (M&A), and divestitures are part of many enterprises’ journeys, driven by evolving business goals like expanding into new geographies or to spin off a line of business. Refer to this post for checking your general readiness for M&A with […]

Many network appliances define idle connection timeout to terminate connections after an inactivity period. For example, appliances like NAT Gateway, HAQM Virtual Private Cloud (HAQM VPC) Endpoints, and Network Load Balancer (NLB) currently have a fixed idle timeout of 350 seconds. Packets sent after the idle timeout expired aren’t delivered to the destination. Some applications or […]

In today’s ecosystem, Software as a Service (SaaS) offerings are primarily delivered in a low friction, service-centric approach over the Internet. These services are often mobile applications or websites delivered via a Content Delivery Network (CDN), such as HAQM CloudFront, that in turn issues requests to the backend SaaS platform. As a SaaS provider, your […]

Introduction: AWS Gateway Load Balancer (GWLB) is an Elastic Load Balancing (ELB) service that allows customers to insert third-party virtual appliances such as firewall, intrusion detection and prevention systems (IDS/IPS), network observability and others, transparently into the traffic path. Application Load Balancer (ALB) and Network Load Balancer (NLB) are reverse proxies and traffic is routed […]

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. […]

Any web application using HAQM CloudFront benefits from the inherent high availability of this AWS service. It’s a globally distributed network that is immune to local hardware failures or network congestion. Furthermore, it’s built on top of the AWS global network, which provides better isolation from the public internet. Finally, it’s designed with various advanced […]

Less than three years ago, we announced the 200th Point of Presence for HAQM CloudFront. Since then, we’ve continued to launch more Points of Presence to support more customers and provide them with enhanced content delivery performance. Today, CloudFront has over 400 Points of Presence in 90 cities and across 47 different countries. The expansion of our network […]

A common situation we see in customer networks is when there are resources with overlapping IP address ranges that must communicate with each other. Frequently this occurs when companies are acquired and have used the same private (RFC1918) address ranges. However, it can also occur when a service provider with a unique IP range must […]
