# Core Concepts

Given Llama Stack's service-oriented philosophy, a few concepts and workflows arise which may not feel completely natural in the LLM landscape, especially if you are coming with a background in other frameworks.

This section covers the key concepts you need to understand to work effectively with Llama Stack:

- **[Architecture](./architecture)** - Llama Stack's service-oriented design and benefits
- **[APIs](./apis)** - Available REST APIs and planned capabilities
- **[API Providers](./api-providers)** - Remote vs inline provider implementations
- **[Distributions](./distributions)** - Pre-packaged provider configurations
- **[Resources](./resources)** - Resource federation and registration
