AWS Infrastructure Services owns the design planning delivery and operation of all AWS global infrastructure. In other words were the people who keep the cloud running. We support all AWS data centers and all of the servers storage networking power and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems with thousands of variables impacting the supply chain and were looking for talented people who want to help.

Youll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And youll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

What does WAF (Web Application Firewall) do We make it easy for customers to author and associate firewall policies to help protect their web applications from attacks by allowing them to configure rules that allow block monitor (count) or CAPTCHA web requests based on conditions that they define. These conditions include IP addresses HTTP headers HTTP body URI strings SQL injection and cross-site scripting. By supporting association with CloudFront Application Load Balancer API Gateway and AppSync customers can protect their applications and resources whether all in on the Cloud maintaining on premise data centers or using a hybrid Cloud approach.


What challenges does the WAF Team tackle

We build a highly available low latency distributed system that allows customers to propagate changes worldwide in minutes to respond to active attacks in real-time. Were fully integrated with several others AWS Services to give customers the insight and control they need.


What is special about the WAF Team

We own the direct customer experience as well as the per request processing of rules for CloudFront API Gateway Application Load Balancer and AppSync. Not only do we build an AWS Security service but were a customer of AWS using other AWS services to provide the solutions to our customers that scale and seamlessly integrate with their existing workflows. Leaders on our team get to solve some of the hardest computer science problems including building highly available distributed micro-services and global scaling across both AWS Regions and CloudFront edge locations.
