The following architectural principles guide Fuchsia's design and development:

* [**Simple:**][simple]
  Fuchsia makes it easy to create, maintain, and integrate software and hardware across a wide range of devices.

* [**Secure:**][secure]
  Fuchsia has a kernel and software model designed for modern computing.

* [**Updatable:**][updatable]
  As a modular operating system, Fuchsia allows the kernel, drivers, and software components to be independently updatable.

* [**Performant:**][performant]
  Fuchsia is designed for real world product requirements and optimized for performance.

The core of the system is [Zircon][glossary.zircon], a kernel and collection of
libraries for handling system startup and bootstrapping.
All other system components are implemented in user space and isolated,
reinforcing the **principle of least privilege**. This includes:

*   Device drivers
*   Filesystems
*   Network stacks
