Firecracker is an exciting new tool for managing virtual machines for serverless applications. It introduces a new approach—microVMs—that can solve a lot of problems for those tasked with optimizing serverless architectures. In this course, learn what this open-source virtual machine manager (VMM) is all about. Discover how Firecracker can work together with both Lambda and Fargate, how to get up and running with a basic Firecracker deployment, and how to create your own microVM and query it using a REST API. Plus, learn how containerd works with Firecracker to create a lightweight container deployment service. (Author: Arun Gupta)
