Sailing into Infinity: Seamlessly managed serverless containers using Kubernetes and AWS Fargate

Serverless computing is a paradigm that promises rapid deployment and speedy scaling, eliminating server management needs. Contentful, an infrastructure team, aims to leverage this for reduced operational overhead. However, integrating serverless solutions into their existing Kubernetes-based tools poses challenges. To address this, they experimented with the virtual-kubelet project, which provides "serverless within Kubernetes" capabilities using Fargate, a service that runs container workloads without managing virtual machines. The setup involves creating a Fargate cluster, adding IAM roles, deploying virtual-kubelet, and running a sample deployment. This hack showed potential for faster scaling while maintaining established workflows, with the added benefit of cost-effectiveness compared to traditional server management.
