Three advanced design patterns for high available applications using Amazon CloudFront
Any web application using Amazon 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 […]
400 Amazon CloudFront Points of Presence
Less than three years ago, we announced the 200th Point of Presence for Amazon 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 […]
Introducing AWS Site-to-Site VPN Private IP VPNs
Update 10/13/22: Added walkthrough with the AWS Management console and link to code in CDK and Terraform. One of the most common ways that customers connect securely to AWS from on premises is by using the AWS Site-to-Site VPN managed IPSec VPN solution. One key benefit our customers look for when using the service is […]
Connecting 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 […]
Introducing IPv6-only subnets and EC2 instances
In June 2021, we announced our continued commitment and innovation towards the enablement of IPv6 on AWS. Today, we take a monumental step forward with the ability to create an IPv6-only architecture on AWS. With this launch, Amazon Virtual Private Cloud (VPC) now allows you to create IPv6-only subnets in your dual-stack VPCs and launch […]
Expedite your IPv6 adoption with PrivateLink services and endpoints
AWS now supports IPv6 for AWS PrivateLink services and endpoints. PrivateLink support for IPv6 expedites IPv6 adoption by decoupling the service consumer and service provider IP protocol version. Even if a service provider has not started to support IPv6 for all their back-end services, service consumers can use IPv6 within their VPCs to access the […]
Introducing IP-based routing for Amazon Route 53
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. Route 53 provides you with the ability to manage traffic to your public domains globally through a variety of routing types, including latency-based routing, geolocation, geoproximity, and weighted routing – all of which can be combined with DNS failover […]
Limit access to your origins using the AWS-managed prefix list for Amazon CloudFront
Amazon CloudFront provides an easy and cost-effective way to distribute content with low latency and high data transfer speeds using a worldwide network of edge locations. To enable requests from CloudFront to access your origins (the source of your content, for example, Amazon Elastic Compute Cloud (Amazon EC2) instances, the security policies on your origin […]
Introduction to Traffic Mirroring to GWLB Endpoints as Target
Network architects need the ability to gain insights into real-time traffic between different resources within their VPCs. Since the announcement of VPC Traffic Mirroring in 2019, the VPC feature has provided this by copying network traffic from elastic networking interfaces (ENIs) on customer’s instances as source, and then sending the traffic to a destination target […]
How Repsol manages and monitors their AWS network with dashboards, alarms and automation
Large enterprises often deploy workloads on Amazon Web Services (AWS) using multiple accounts. This helps isolate workloads, manage permissions more easily, and simplifies cost allocation. However, managing a multi-account environment can make your network topology more complex and requires additional monitoring and automation. At Repsol, a global multi-energy company present throughout the entire value chain, […]
