The Interface VPC Endpoints for Amazon S3 allow security administrators to control which users can access which data in S3 from on premises and cross-Region using their […]
Read MoreTarget 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 […]
Read MoreComplying with city-level embargos using Amazon CloudFront
Introduction You may run into occasions where, due to sanctions from governmental organizations like OFAC (Office of Foreign Assets Control), you need to implement granular city-level embargos for your websites. This blog will walk you through an approach to achieving this using Amazon CloudFront geolocation headers and Amazon CloudFront Functions. Note that geographical restrictions at […]
