AWS Fargate

AWS Fargate is a serverless compute engine for containers provided by Amazon Web Services that enables developers to run containers without managing the underlying EC2 instances or clusters. Unlike Kubernetes, which requires explicit node provisioning and cluster management, Fargate abstracts the infrastructure entirely: the developer specifies CPU and memory requirements, and AWS provisions, scales, and maintains the compute capacity automatically. This model sits between the raw infrastructure of EC2 and the fully managed abstraction of AWS Lambda, offering container flexibility with serverless operational simplicity.

Fargate's architecture is built atop AWS's existing container infrastructure, providing a common runtime for both ECS and EKS workloads. This dual support is strategically significant: organizations can adopt Fargate's serverless compute model without abandoning their existing orchestration investments. However, Fargate introduces a cost premium over self-managed EC2, and the opacity of its resource allocation can make performance debugging challenging. The trade-off is characteristic of managed services: operational simplicity in exchange for control and, often, price.

— Fargate represents the cloud provider's dream: the customer brings the application, the provider brings everything else, and the boundary between them is drawn so that the provider can optimize while the customer cannot observe. Whether this asymmetry is a fair trade depends on whether the provider's optimizations actually benefit the customer, or merely the provider's margins.
