A structural perspective that shows how software components are distributed across physical computing resources and infrastructure in a system's runtime environment.

A deployment view represents the physical distribution and allocation of software components across hardware infrastructure, forming a critical aspect of software architecture documentation. This view addresses how the various parts of a system are deployed, configured, and connected in the actual runtime environment.

The deployment view emerges from the need to bridge the gap between logical system architecture and physical implementation. It serves as a crucial tool for understanding and managing the operational complexity of modern distributed systems.

Key elements typically represented in a deployment view include:

Physical nodes (servers, devices, cloud instances)
Software artifacts and components
Network connections and protocols
Hardware requirements
Runtime dependencies
System boundaries and interfaces

The deployment view helps stakeholders understand:

Physical topology of the system
Hardware-software mapping
Network configuration requirements
System resilience considerations
Performance characteristics

This perspective is particularly valuable for:

System operations teams managing infrastructure
System deployment engineers
Performance engineers
Security architects
System monitoring specialists

The deployment view relates strongly to other architectural perspectives:

Component View - showing logical components that map to physical deployments
Runtime View - depicting dynamic aspects of the deployed system
Network View - focusing on communication patterns

In modern distributed systems, deployment views have evolved to accommodate:

The deployment view helps manage system complexity by providing a clear mapping between logical architecture and physical implementation. It supports important system qualities like:

This view is particularly important in the context of DevOps practices, where it helps bridge the gap between development and operations by providing a shared understanding of how the system exists in its runtime environment.

Understanding the deployment view is essential for:

Capacity planning
Resource allocation
Disaster Recovery planning
System Migration planning
Performance optimization

The deployment view represents a critical interface between abstract architectural decisions and concrete implementation realities, making it an essential tool for modern system design and operation.
