Architecture Health Check | Verpex Solutions

Silent bottlenecks and technical debt can cripple a growing business. Use this 20-point scorecard to evaluate your current software ecosystem against the rigorous engineering standards maintained at Verpex Solutions Pty Ltd. Check the box for every statement that is currently true for your production environment.

1. Database & Data Integrity

Strict Query Profiling

No queries result in full table scans. All slow queries are actively profiled using EXPLAIN before reaching production.

Optimized Indexing

Indexes are carefully constructed using the leftmost prefix rule. High-cardinality columns are prioritized over boolean flags.

Decoupled Data Layer

The architecture utilizes a Master DB for write operations and a Slave DB for read replication to prevent locking and performance degradation.

Version-Controlled Schema

ORM auto-generation is disabled in production. All database schema changes are managed via strict migration scripts (e.g., Flyway or Liquibase).

2. Infrastructure & Scalability

No Single Point of Failure

The application is deployed across multiple web servers or containerized pods, ensuring hardware failure does not cause downtime.

Active Load Balancing

All public traffic is routed through an Application Load Balancer or NGINX reverse proxy that performs SSL termination and health checks.

Stateless Processing

Application servers do not store local session data, allowing the infrastructure to scale horizontally on demand.

Automated Backups

Automated snapshot backups are scheduled and retained according to a strict Disaster Recovery policy, with proven restoration capabilities.

3. Security & Access Control

Root Access Disabled

Direct root login via SSH is permanently disabled on all Linux instances. Engineers use distinct user accounts with cryptographic keys.

Private Subnet Isolation

Database servers and core application nodes do not have public IP addresses and reside entirely within secure, private network subnets.

IP Whitelisting

Administrative and SSH access is restricted via cloud firewalls to known, whitelisted developer IP addresses only.

Patch Management

A rigorous schedule exists for applying OS-level security patches and critical package updates without disrupting the live application.

4. Code Quality & Architecture

Constructor Injection

The codebase avoids field injection. Dependencies are managed via constructor injection to guarantee component immutability and testability.

Immutability by Default

Variables, domain object fields, and return collections are declared final or unmodifiable wherever logically possible.

DRY & SOLID Principles

Business logic is never duplicated. Classes adhere to the Single Responsibility Principle, cleanly separating routing, services, and data access.

Strict Exception Handling

Exceptions are never swallowed. Catch blocks either recover the system state or log detailed, contextual identifiers before re-throwing.

5. Observability & Delivery

Real-Time Metrics

Tools like Prometheus are actively scraping CPU, memory, and disk I/O metrics across the entire infrastructure footprint.

Visual Dashboards

Engineering teams have access to centralized Grafana dashboards providing a real-time, visual pulse of system health.

Automated Alerting

Threshold-based alerts are configured to immediately notify developers of abnormal resource consumption before users report an outage.

Semantic Deployment

All deployments are tied to specific, immutable Git tags via an automated CI/CD pipeline, ensuring immediate rollback capability.

Your Architecture Score: 0 / 20

Check the boxes above to evaluate your infrastructure stability rating.

17 - 20: Enterprise Grade

Your systems are robust, scalable, and secure. You possess the architectural foundation required for rapid growth and minimal technical debt.

11 - 16: Stable but Vulnerable

Your application functions, but relies on fragile components. Spikes in traffic or hardware failures will likely cause degraded performance or outages. Refactoring is required.

0 - 10: Critical Risk

Your infrastructure represents a severe business risk. Data integrity, security, and uptime are heavily compromised. Immediate architectural intervention is necessary.
