About Fly.io

Fly.io is a platform-as-a-service that runs applications in lightweight micro-VMs (using Firecracker) close to end users across a global edge network. It allows developers to deploy full-stack applications, databases, and services to dozens of regions worldwide with minimal configuration using a CLI-driven workflow. The platform is particularly well-suited for developers who want the control of infrastructure without the overhead of managing Kubernetes or traditional cloud VMs. It supports Docker containers and various runtimes, making it flexible for different tech stacks. Fly.io differentiates itself by combining the simplicity of a PaaS with the power of deploying actual virtual machines at the edge.

About Azure

It serves everyone from solo developers experimenting with side projects to Fortune 500 enterprises running mission-critical workloads. Its deep integration with the Microsoft ecosystem — including Visual Studio, GitHub, and Active Directory — makes it particularly strong for organizations already invested in Microsoft tools. Azure supports a wide range of programming languages, frameworks, and operating systems, including robust Linux support, making it more versatile than many expect.
