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 […]
Read MoreConnecting Networks with Overlapping IP Ranges
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 […]
Read MoreUsing Amazon CloudFront with AWS Lambda as origin to accelerate your web applications
In this blog, you will learn how to use the Lambda Function URL feature to define a AWS Lambda Function as origin for Amazon CloudFront. Lambda Function URL capability provides a dedicated HTTPS endpoint for your Lambda function deployed in an AWS Region. Function URLs are a great fit for use cases where you must […]
Read MoreBuilding Multi-Region AWS Client VPN with Microsoft Active Directory and Amazon Route 53
Introduction Organizations often require a secure connection between their users and resources on internal networks. For organizations with a global workforce, traditional virtual private network (VPN) solutions can be difficult to scale. Providing a single VPN endpoint creates a single point of failure: an outage would mean loss of connectivity to critical IT infrastructure. Authenticating […]
Read MoreTarget Group Load Shedding for Application Load Balancer
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 […]
Read MoreUsing Route 53 Resolver DNS Firewall Logs with CloudWatch Contributor Insights and Anomaly Detection
Introduction The Domain Name System (DNS) is one of the most critical components for almost any network as every service relies on a functional DNS service. Amazon Route 53 Resolver (sometimes referred to as “AmazonProvidedDNS” or the “.2/+2 resolver”) provides a highly available and scalable DNS service that customers have come to rely upon for their recursive DNS […]
Read MoreInfluencing Traffic over Hybrid Networks using Longest Prefix Match
Introduction Many organizations use hybrid networks to connect on-premises data centers to the cloud. These networks often use both AWS Direct Connect and private WAN MPLS links to connect data centers to cloud resources and to each other. With multiple connections, organizations need to be able to control the path that network traffic will follow […]
Read MoreHow AWS is helping to secure internet routing
The internet works reliably, in large part, on the basis of a key technology called Border Gateway Protocol (BGP). BGP is a means by which all junction points on the internet (routers) communicate with each other to dynamically establish the correct (and correctly weighted) paths that network packets should follow to traverse the global networking […]
Read MoreCloudFront migration series (Part 1) – introduction
September 8, 2021: Amazon Elasticsearch Service has been renamed to Amazon OpenSearch Service. See details. This is the first post in a blog series about Amazon CloudFront migrations. CloudFront works with other AWS edge networking services, to provide content delivery, perimeter security, end-user routing, and edge compute. CloudFront is a Content Delivery Network (CDN), which […]
Read MoreSimplify SD-WAN connectivity with AWS Transit Gateway Connect
SD-WANs, or Software Defined Wide Area Networks, have long been used to connect data centers and branch offices over the public internet. Today, those networks must also extend to the cloud. However, traditional SD-WAN infrastructure is not always well suited for this task—significantly increasing complexity and operational burden. At the same time, many AWS customers […]
