Earlier this year, we released technical guidance regarding three advanced design patterns for highly available applications using Amazon CloudFront and Amazon Route 53. In this post, we dive deeper into CloudFront origin failover, Amazon Route 53 DNS failover, and the hybrid origin failover approach to further enhance the availability of your web applications. We also […]

Introduction Since its launch in 2020, AWS Transit Gateway Connect has provided a native way for you to connect third-party SD-WAN appliances to an AWS Transit Gateway. Connect attachments use Generic Routing Encapsulation (GRE) tunnels and Border Gateway Protocol (BGP) to exchange routes between the Transit Gateway and an appliance.

AWS Verified Access (AVA) offers a solution to the challenges faced by enterprises by managing remote workforce connectivity through traditional remote access VPNs. It allows remote employees to securely access corporate applications over the Internet while authenticating and authorizing each request. Unlike traditional VPN systems, which lack granularity for application-level authentication and authorization, AVA implements […]

Introduction Customers use multi-region architecture to achieve application resiliency such as Active-Active or Disaster Recovery (DR). Depending on DR strategy, customers may need to have failover from one region to the next. DR strategies are covered off in detail in a prior AWS Blog. DR strategies include either an Active/Passive or Multi-Site Active/Active approaches. Active/Passive […]

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 […]

As organizations grow, they must often serve geographically dispersed users with low latency, prompting them to have a distributed global infrastructure in the cloud. In this article, we describe how to deploy global API endpoints to reduce latency for end-users while increasing an application’s availability. By using the AWS Global Network and Amazon CloudFront to deploy applications into multiple […]

At re:Invent 2020, AWS introduced  Gateway Load Balancer (GWLB), an AWS service that helps you deploy, scale, and manage third-party virtual network appliances, such as firewalls, intrusion detection and prevention systems, and others. GWLB is a type of load balancer under the Elastic Load Balancing (ELB) family. Other load balancers within the ELB family include […]

In this post, you’ll learn about the ‘multi-function packager’ framework that handles the assembly and execution of discrete Edge functions. Amazon CloudFront is a content delivery network (CDN) service that improves the performance, availability, and security of your application, allowing you to serve a consistent experience to your viewers globally. Lambda@Edge and CloudFront Functions are the […]

Observability is critical for operating any system. It should tell whether the system is functioning correctly, provide insights in user experience, notify when issues occur, and help to locate the root cause. However, building an observable video streaming system can be a challenge for customers as it requires collecting, correlating, and analyzing data from several […]

In this post, you’ll learn how to secure and accelerate the delivery of Drupal-based websites using Amazon CloudFront, AWS Web Application Firewall (AWS WAF), and Amazon CloudFront Functions. CloudFront is a content delivery network service (CDN) offering improved security and acceleration of the content served through it. This is true for static cacheable content and […]
