Rapidly recover from application failures in a single AZ

Today we would like to introduce “zonal shift”, a new capability of Amazon Route 53 Application Recovery Controller (ARC) that is built-into Elastic Load Balancers (ELBs) and available in preview. Performing a zonal shift enables you to achieve rapid recovery from application failures within a single Availability Zone (AZ). In this post, we’ll explain how […]

Introducing AWS Gateway Load Balancer Target Failover for Existing Flows

Introduction: AWS Gateway Load Balancer (GWLB) is an Elastic Load Balancing (ELB) service that allows customers to insert third-party virtual appliances such as firewall, intrusion detection and prevention systems (IDS/IPS), network observability and others, transparently into the traffic path. Application Load Balancer (ALB) and Network Load Balancer (NLB) are reverse proxies and traffic is routed […]

Target 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 […]

Application Load Balancer-type Target Group for Network Load Balancer

Application Load Balancer (ALB) is a fully managed layer 7 load balancing service that load balances incoming traffic across multiple targets, such as Amazon EC2 instances. ALB supports advanced request routing features based on parameters like HTTP headers and methods, query string, host and path based routing. ALB also offloads important capabilities including TLS termination, […]

Using AWS Lambda to enable static IP addresses for Application Load Balancers

Update: On September 27th, 2021, we launched Application Load Balancer(ALB)-type target groups for Network Load Balancer (NLB). With this launch, you can register ALB as a target of NLB to forward traffic from NLB to ALB without needing to actively manage ALB IP address changes through Lambda. You can also use AWS Global Accelerator to […]

Resolve DNS names of Network Load Balancer nodes to limit cross-Zone traffic

Introduction Network Load Balancer (NLB), part of the Elastic Load Balancing Family, is the flagship Layer 4 load balancer for AWS. It offers elastic capacity, high performance, and integration with many other AWS services (such as Amazon EC2 Auto Scaling). NLB is designed to handle millions of requests per second while maintaining ultra-low latency, improving […]

Accessing an AWS API Gateway via static IP addresses provided by AWS Global Accelerator

Introduction In this article, I will walk you through the steps to configure Amazon API Gateway in combination with AWS Global Accelerator to present Internet-facing API via static IP addresses to end users. This design addresses the need for static IP safelisting and also provides additional performance benefits to end users by sending user’s traffic […]

Securing ingress using security solutions and AWS Transit Gateway

Introduction Internet-facing applications, by their nature, have a larger attack surface and are exposed to categories of threats most other types of applications will never have to face. Having the necessary protection from attacks on these types of applications, and minimizing the impact of attacks, are a core part of any security strategy. Traditional AWS […]

Scaling network traffic inspection using AWS Gateway Load Balancer

Updated “Cross-zone load balancing and appliance failures” section on 25th March, 2021 Organizations use next-generation firewalls (NGFW) and intrusion prevention systems (IPS) as part of their defense in depth strategy. In an on-premises network, these often take the form of dedicated hardware or software or virtual “appliances.” As companies move to the cloud, they want […]

Introducing AWS Gateway Load Balancer: Supported architecture patterns

Customers often ask me how they can maintain consistent policies and practices as they move to the cloud, especially as it relates to using the network appliances. They trust third-party hardware and software appliances to protect and monitor their on-premises traffic, but traditional appliance deployment models are not always well suited to the cloud. Last […]
