Encrypt DNS queries using DNS-over-HTTPS (DoH) with Amazon Route 53 Resolver Endpoints
Customers frequently use on-premises DNS infrastructure to resolve DNS queries for internal domains. In 2018, we announced Amazon Route 53 Resolver endpoints, which enable customers to integrate Route 53 with their on-premises DNS infrastructure for hybrid DNS resolution. In 2023, we improved this integration by providing customers the ability to encrypt DNS queries and responses […]
Demystifying AWS Data Transfer services to build secure and reliable applications
For cloud users, evaluating data transfer services can be complex, especially when the internal engineering that manages security and delivers high availability and low latency is often abstracted. We are starting a series of posts intended to demystify AWS Data Transfer services and to clarify exactly what Amazon Web Services (AWS) users get when they […]
Removing Unassociated Elastic IPs
Have you ever wondered why your Elastic IP (EIP) count is growing, and what’s behind the “ElasticIP:IdleAddress” line item on your AWS bill? This could be because there is an hourly charge for EIP addresses that are not associated with a running instance, when an EIP is associated with a stopped instance, or when there […]
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 […]
Monitoring EC2 Connection Tracking utilization using a new network performance metric
In 2020, Amazon Elastic Compute Cloud (Amazon EC2) announced new network performance metrics for EC2 instances made available using ENA driver and Amazon CloudWatch agent. We covered the launch in this post. These network performance metrics give customers visibility into the number of packets queued or dropped when an instance’s networking allowances, such as Network […]
Amazon EC2 instance-level network performance metrics uncover new insights
Introduction Amazon EC2 provides instance-level metrics that measure CPU, disk, and network performance. These metrics include bytes and packets in/out and collected by default and can be viewed in Amazon CloudWatch. Amazon EC2 has recently announced additional high-resolution instance level network performance metrics for Elastic Network Adapter (ENA). With these new metrics you can gain […]
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 […]
Celebrate 15 Years of Amazon EC2 with Twitch Livestream Events
When Amazon Elastic Compute Cloud (EC2) launched in 2006, the world looked very different. Cellphones weren’t smart, and no one had even heard of an App Store. Fast forward 15 years, and the world has become more digitized with many companies building their success by running secure, reliable, and scalable workloads in the cloud. Amazon […]
