Every new project starts the same way: someone provisions new infrastructure, copies configuration from the last project, tweaks a few values, and hopes nothing breaks. It works—until it doesn't.

As organizations scale, this approach creates exponential complexity. Each project becomes a snowflake. Knowledge lives in the heads of the people who built it. And when those people move on, maintaining the infrastructure becomes archaeology.

The Cost of Reinvention

We've seen the same pattern across dozens of enterprises:

• Teams spend 40-60% of infrastructure time recreating what already exists elsewhere
• Security and compliance configurations drift between environments
• Onboarding new team members takes months instead of days
• Incidents multiply because each environment behaves slightly differently

What Pattern-Driven Means

Pattern-driven infrastructure flips this model. Instead of starting from scratch, you start with proven patterns that encode organizational best practices. These patterns are:

• Composable - Combine smaller patterns into larger architectures
• Versioned - Track changes over time, roll back when needed
• Tested - Validate patterns before deployment
• Documented - Self-describing through code

Nexus Blocks in Practice

This is why we built Nexus Blocks as the foundation of Teals Nexus. A Block is a reusable, composable unit that encapsulates infrastructure, configuration, and deployment logic together.

When a team needs a new service, they don't start from scratch. They compose existing Blocks, customize the parameters, and deploy. The platform handles orchestration, dependency management, and compliance validation automatically.
