Platform Infrastructure

Overview

Most people think infrastructure means servers, storage, and networks.

Architects think about infrastructure differently.

Infrastructure is the platform on which every application, business process, integration, data platform, observability platform, security platform, and AI capability depends.

If infrastructure performs well, organizations can innovate safely and rapidly.

If infrastructure performs poorly, every technology initiative becomes slower, more expensive, and riskier.

Infrastructure Relationship Model

Why Infrastructure Exists

• Provide Compute Resources
• Provide Storage Services
• Provide Network Connectivity
• Enable Security
• Support Reliability
• Enable Scalability
• Support Business Operations
• Enable Digital Transformation

Infrastructure itself rarely creates business value directly.

Its value comes from enabling everything else.
