Many Amazon Web Services (AWS) customers look to extend their Multiprotocol Label Switching (MPLS) networks into the cloud. MPLS networks offer reliable and performance-optimized routes for data, making them a preferred choice for enterprise connectivity. AWS Direct Connect further enhances this by providing a dedicated network link from an organization’s on-premises networks to AWS. This […]

Anyone who has worked with Microsoft Active Directory Domain Services (AD DS) and domain-joined workloads in the past likely knows how critical proper DNS resolution is to healthy operations. Even if you haven’t worked with AD DS workloads, if you are reading this post, you have likely heard of some outage that was caused by […]

In May 2024, Amazon Web Services (AWS) launched a new feature for internet-facing Application Load Balancers. This enhancement allows you to provision an internet-facing Application Load Balancer without needing public IPv4 addresses, enabling clients to connect using only IPv6 addresses. To connect, clients resolve the AAAA DNS records assigned to the Application Load Balancer. The […]

Amazon VPC IP Address Manager (IPAM) is a VPC feature that allows you to plan, track, and monitor IP addresses for your AWS workloads. Until now, VPC IPAM allowed you to allocate CIDR blocks and monitor them at the VPC level. With a recent feature enhancement in VPC IPAM, you can now manage CIDR allocations […]

This is a guest post co-written with Mike Mosher, Sr Principal Cloud Platform Network Architect, and Daniel Lee, Lead Cloud Platform Engineer, from Experian. Experian is a global technology company that offers credit risk, fraud, targeted marketing, and automated decisioning solutions. We are an AWS early adopter and have embraced the cloud to drive digital […]

In April 2023, AWS increased several AWS Direct Connect quota limits, as you have asked for increased scale and capacity for hybrid cloud connectivity. With the new limits, you can now create up to four Transit Virtual interfaces (VIFs) per AWS Direct Connect dedicated connection. The maximum number of prefixes has increased to 200 for […]

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, […]

Update – 3rd May 2023 With this update, zonal shift for Amazon Route 53 Application Recovery Controller is now also available in the following AWS Regions. Learn more in the updated What’s New post or zonal shift documentation. Today we’re introducing zonal shift, a new capability of Amazon Route 53 Application Recovery Controller (Route 53 […]

We’ll start by outlining how AWS services provide reliability using control planes and data planes, then share high-level design principles for creating a failover mechanism. Finally, we’ll explain the features of Route 53 that make your DR approach more effective.

Load Shedding Load shedding is the practice of sacrificing enough application traffic to keep partial availability in the presence of an overload condition. Used in conjunction with strategies like load balancing, load shedding helps applications support service level agreements (SLAs) when increased traffic overwhelms available system resources. While the cloud’s elasticity reduces the need for […]
