Infrastructure as Code was supposed to solve the complexity problem. Write your infrastructure once, version it, and reuse it. In practice, most organizations end up with thousands of lines of configuration that nobody fully understands.

Nexus Blocks take a different approach: instead of writing infrastructure code, you compose pre-built, tested components.

What Is a Nexus Block?

A Block is a reusable unit of deployment that encapsulates:

• Infrastructure resources (compute, storage, networking)
• Configuration and secrets management
• Deployment logic and health checks
• Compliance and security controls
• Observability integration

Composition Over Configuration

Instead of writing custom Terraform or CloudFormation, you compose Blocks. Need a containerized service with a database and message queue? Combine the appropriate Blocks, configure the parameters, and deploy.

The Nexus engine handles the rest: dependency ordering, health verification, rollback on failure, and compliance validation.

Enterprise-Ready Patterns

Blocks encode organizational best practices. When your security team approves a Block, every deployment using that Block inherits those security controls. No more chasing teams to implement the latest security requirements—update the Block, and every consumer benefits.
