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 […]

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 […]

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 […]

Lambda functions as targets for Application Load Balancers

As of today, Application Load Balancers (ALBs) now support AWS Lambda functions as targets. Build websites and web applications as serverless code, using AWS Lambda to manage and run your functions, and then configure an ALB to provide a simple HTTP/S frontend for requests coming from web browsers and clients. Triggering a Lambda Function from […]
