An increasing number of organizations are adopting IPv6 in their environments, driven by the public IPv4 space exhaustion, private IPv4 scarcity, and the need to provide service availability to IPv6-only clients. While undergoing this transformation, customers sometimes find it difficult to assess application behavior in IPv6-enabled environments on AWS. In this blog post, we show […]

AWS Global Accelerator now offers dual-stack accelerators that let you route both IPv4 and IPv6 traffic to Amazon Elastic Compute Cloud (Amazon EC2) instances as endpoints, in addition to Application Load Balancers. In this post, we describe the benefits of using dual-stack accelerators with IPv6 EC2 endpoints, and go through a step-by-step guide for adding […]

Volumetric attack is one of the most common type of cyberattack, where a web application is overwhelmed with an enormous number of HTTP requests. This flood of excessive requests puts a strain on the application’s servers, leading to degraded performance, increased latency for legitimate users and in severe cases, resource exhaustion. AWS WAF’s rate-based rules […]

In this post, we discuss how to architect Zero Trust based remote connectivity on AWS. Specifically, we will be exploring how to integrate Verified Access with CrowdStrike, a device trust provider. This solution builds upon the Okta-based identity provider integration previously published in this AWS post. Zero Trust is a conceptual model, and an associated […]

In a modern distributed system, identifying where a problem has occurred is not a trivial task. In fact, it’s a key capability that an organization must master to maintain its competitiveness. Tracing is a great methodology to be used for this purpose. It creates a series of formatted logs with an identifier called Trace ID, which […]

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 […]

AWS WAF offers advanced features for filtering undesired web application traffic, such as Bot Control and Fraud Control. These intelligent threat mitigations include techniques such as client-side interrogations using JavaScript challenges or CAPTCHA, as well as client-side behavioral analysis. Implementing these techniques on a web page with a same-origin access is simple. When a cross-domain […]

Virtual Routing and Forwarding (VRF) is a traditional network feature which uses isolated logical routing domains (route tables/VRFs) to keep network traffic separated within the same physical infrastructure. Customers ask us how to combine the segmentation provided by AWS Cloud WAN and AWS Transit Gateway with VRF isolation when connecting their on-premises networks to AWS. […]

You can now add AWS WAF protections to Amazon CloudFront distributions with one click. In this walkthrough, we will guide you through setting up and monitoring protections offered by this new feature along with pricing and additional security recommendations. This blog relates to Amazon CloudFront — a AWS service that you can use to deliver […]

When workload performance depends on the number of networking connections, traditional load balancing metrics like CPU load or memory utilization do not provide the information you need in order to make scaling decisions. In this post, we explore a solution that automatically scales backend connections of a Network Load Balancer (NLB) target group based on […]
