In its mission to simplify building and running cloud-native applications for users, Amazon has announced the GA of AWS App Runner, a new purpose-built container application service. With security top of mind for most organizations shifting to the cloud, Sysdig has collaborated with AWS to enable threat detection for the new platform.
Fargate offers a great value proposition to AWS users: forget about virtual machines and just provision containers. Amazon will take care of the underlying hosts, so you will be able to focus on writing software instead of maintaining and upgrading a fleet of Linux instances. Fargate brings many benefits to the table, including small maintenance overhead, lower attack surface, and granular pricing. However, as any cloud asset, leaving your AWS Fargate tasks unattended can lead to nasty surprises.
Securing AWS Fargate serverless workloads can be tricky as AWS does not provide much detail about the internal workings. After all… it’s not your business, AWS manages the scaling of underlying resources for you. :) While the security and stability of Fargate’s system is an inherent feature, Fargate follows a shared responsibility model, where you still have to take care of securing those parts specific to your application..
