Architecture

Buildly Product Labs is built on a modern, scalable microservices architecture that follows proven patterns for enterprise-grade applications. This page outlines the key architectural patterns and design principles that power the platform.

Architecture Overview

Buildly follows a component-driven microservices architecture that emphasizes modularity, scalability, and maintainability. The platform is designed around several core architectural patterns that work together to provide a robust foundation for product management workflows.

Note

Architecture Diagram Coming Soon: A visual diagram showing the relationship between frontend, gateway, core services, and logic services will be added here.

Core Architectural Patterns

1. API Gateway Pattern

Single Point of Entry

All client requests flow through a centralized API gateway that provides:

  • Unified API Surface: Single URL endpoint (dev-api.myapp.io)

  • Service Discovery: Automatic registration and discovery of backend services

  • Load Balancing: Intelligent request distribution across service instances

  • Rate Limiting: Protection against abuse and overload

  • API Versioning: Support for multiple API versions

Service Registration Flow:

Frontend Application (dev-app.myapp.io)
        ↓
API Gateway (dev-api.myapp.io)
        ↓
Buildly Core + Logic Services
        ↓
- /documents → Documents Service
- /crm → CRM Service
- /appointments → Appointments Service

2. Microservices Architecture

Logic Services

Buildly implements a pure microservices pattern where each business capability is implemented as an independent service:

  • Documents Service: File management and document workflows

  • CRM Service: Customer relationship management

  • Appointments Service: Scheduling and calendar management

  • Custom Services: Domain-specific business logic

Key Characteristics:

  • Independence: Each service can be developed, deployed, and scaled independently

  • OpenAPI Standard: All services follow OpenAPI/Swagger specifications

  • Database per Service: Each service owns its data store

  • Technology Agnostic: Services can use different programming languages and frameworks

3. Data Mesh Pattern

Unified Data Layer

The Data Mesh pattern enables seamless data integration across distributed services:

Data Aggregation:

Service 1 Data → UUID, Name, Type, Description
Service 2 Data → UUID, Name, Type, Description
Service 3 Data → UUID, Name, Type, Description
        ↓
Data Mesh (Buildly Core)
        ↓
Aggregated REST API Response

Benefits:

  • Cross-Service Joins: Query data across multiple services seamlessly

  • Data Consistency: Maintain referential integrity across service boundaries

  • Performance Optimization: Intelligent caching and query optimization

  • Schema Evolution: Handle data model changes gracefully

4. Centralized Authentication & Authorization

Single Sign-On (SSO)

Buildly Core manages authentication and authorization across all services:

Authentication Flow:

User Login → Buildly Core → JWT Token → All Services

Permission Model:

  • Role-Based Access Control (RBAC): Default roles auto-created

  • Service-Level Permissions: Fine-grained access control per service

  • Cross-Service Authorization: Unified permission checks

  • User Management: Centralized user lifecycle management

5. Workflow Template Pattern

Reusable Process Orchestration

Buildly implements configurable workflow templates that can be reused across services:

Template Structure:

Workflow Template
├── Level 1 → Related Level → Related Workflow
└── Level 2 → Related Level 1 → Related Workflow 2

Capabilities:

  • Process Trees: Build complex multi-step workflows

  • Navigation Flows: Define user journey patterns

  • Cross-Service Workflows: Orchestrate processes across multiple services

  • Template Reusability: Share workflow patterns across projects

6. Module Pattern (Core Extensions)

Pluggable Architecture

Buildly Core supports modules that run within the core application:

  • Connection Modules: Service integration and communication

  • Security Modules: Authentication and authorization extensions

  • Data Transport Modules: Message queuing and event processing

  • Partner Integration Modules: Third-party system connectors

Deployment Architecture

Container-First Design

Buildly is designed for modern container orchestration platforms:

Kubernetes Deployment:

  • Namespace Isolation: Each application gets its own Kubernetes namespace

  • Pod Management: Automatic pod creation for Buildly Core and Logic Services

  • Service Mesh: Istio/Linkerd integration for service communication

  • Auto-Scaling: Horizontal pod autoscaling based on load

Database Strategy:

  • Database per Service: Each Logic Service has its own database

  • Cluster Management: Databases deployed in managed clusters

  • Backup & Recovery: Automated backup strategies per service

  • Migration Support: Database schema evolution and migration tools

Cloud-Native Patterns

Infrastructure as Code:

  • Automated Provisioning: Infrastructure deployment via Terraform/CloudFormation

  • Environment Parity: Consistent environments from development to production

  • Blue-Green Deployments: Zero-downtime deployment strategies

  • Monitoring & Observability: Integrated logging, metrics, and tracing

Security Architecture

Defense in Depth

Multiple Security Layers:

  1. Network Security: VPC isolation, security groups, and network policies

  2. API Security: OAuth 2.0, JWT tokens, and API rate limiting

  3. Application Security: Input validation, output encoding, and CSRF protection

  4. Data Security: Encryption at rest and in transit

  5. Infrastructure Security: Container scanning and vulnerability management

Compliance & Governance:

  • GDPR Compliance: Data privacy and user consent management

  • SOC 2 Type II: Security and availability controls

  • OWASP Top 10: Protection against common web vulnerabilities

  • Audit Logging: Comprehensive audit trails for compliance

Performance & Scalability

Horizontal Scaling

Auto-Scaling Capabilities:

  • Load-Based Scaling: Automatic scaling based on CPU/memory usage

  • Queue-Based Scaling: Scale based on message queue depth

  • Predictive Scaling: ML-driven capacity planning

  • Multi-Region Deployment: Global distribution for low latency

Performance Optimization:

  • Caching Layers: Redis/Memcached for session and application caching

  • CDN Integration: Static asset delivery via CloudFront/CloudFlare

  • Database Optimization: Connection pooling and query optimization

  • Async Processing: Background job processing for long-running tasks

Monitoring & Observability

Three Pillars of Observability

Metrics:

  • Application Metrics: Response times, throughput, error rates

  • Infrastructure Metrics: CPU, memory, disk, network utilization

  • Business Metrics: Feature usage, user engagement, conversion rates

Logging:

  • Structured Logging: JSON-formatted logs with correlation IDs

  • Centralized Logging: ELK/EFK stack for log aggregation

  • Log Retention: Configurable retention policies per environment

Tracing:

  • Distributed Tracing: OpenTracing/Jaeger for request flow visualization

  • Performance Profiling: APM tools for bottleneck identification

  • Error Tracking: Sentry/Rollbar for real-time error monitoring

Development Workflow

Continuous Integration:

  • Automated Testing: Unit, integration, and end-to-end test suites

  • Code Quality: SonarQube/CodeClimate for static analysis

  • Security Scanning: Container and dependency vulnerability scanning

  • Build Automation: Docker image building and registry management

Continuous Deployment:

  • GitOps Workflow: Infrastructure and application deployment via Git

  • Environment Promotion: Automated promotion from dev → staging → production
