Operating System
Definition
The main software that manages your computer and runs other programs. Like the manager of a building who makes sure everything works properly.
Use Cases
- Netflix: Running large-scale streaming and backend services on Linux servers in the cloud — Netflix runs many services on Linux-based Amazon EC2 instances (commonly using hardened Linux distributions and custom tooling) to host microservices, APIs, and supporting infrastructure. (Linux provides a stable, customizable platform that supports high scalability and operational automation for global streaming workloads.)
- Spotify: Operating backend services on Linux to support music streaming and data processing — Spotify has used Linux extensively for server-side workloads, leveraging Linux environments for service deployment and operational tooling across large fleets. (A consistent OS platform helps standardize deployments, improve reliability, and support rapid iteration across many services.)
- NASA: Using Linux on mission-critical and research computing systems — NASA has used Linux across various high-performance computing and research environments where control, transparency, and customization are important. (Linux enables flexibility and performance tuning for specialized workloads and scientific computing needs.)
Frequently Asked Questions
- What's the difference between an Operating System and an application?
- An operating system (like Windows, macOS, or Linux) is the foundation that manages hardware (CPU, memory, disk, network) and provides services that programs use. An application (like Chrome, Microsoft Word, or a mobile game) runs on top of the operating system to perform a specific task for the user.
- When should I use a specific Operating System in the cloud (Linux vs Windows)?
- Choose Linux when you want a lightweight, widely supported OS for web servers, containers, open-source tools, and cost-sensitive workloads (many Linux distributions have no OS license fee). Choose Windows when you need Windows-only software (like .NET Framework apps, certain enterprise tools, or Microsoft SQL Server in Windows-only setups) or when your team relies on Windows administration and tooling.
- How much does an Operating System cost in cloud computing?
- Cost depends on the OS and how you run it. Many Linux distributions are free to use (you mainly pay for the VM/compute, storage, and networking). Windows typically includes a license cost that is bundled into the hourly VM price on most clouds. Some enterprise Linux options (like Red Hat Enterprise Linux) may include subscription costs, either bundled into the VM rate or purchased separately, depending on the provider and licensing model.
