SyncApp Architecture

SyncApp Architecture

This document outlines the architecture of SyncApp, a robust data ingestion and synchronization platform.

System Overview

SyncApp is designed to connect, transform, and synchronize data between various data sources and destinations. The system is built with scalability, reliability, and security in mind, following a microservices-inspired architecture with clear separation of concerns.

Component Description

1. External Systems

Data sources and destinations that SyncApp connects with, including: - Relational databases (PostgreSQL, MySQL) - Cloud data warehouses (BigQuery, Redshift) - SaaS platforms (Salesforce, HubSpot) - API endpoints and file systems

2. Load Balancer Layer

  • NGINX: Performs load balancing, SSL termination, routing, and caching

3. Web Application Layer (Django)

  • Django Web Application: Provides UI, REST API, authentication, and configuration management
  • Designed to be stateless for horizontal scaling

4. Data Storage Layer

  • PostgreSQL: Primary database for users, connections, configs, history, and metadata
  • Redis: Used for caching, session storage, rate limiting, and temporary data

5. Message Broker

  • RabbitMQ: Queues sync jobs, enables communication, provides reliable delivery

6. Task Processing Layer

  • Celery Workers: Process sync jobs asynchronously, handle ETL operations

7. Monitoring & Logging

  • Prometheus & Grafana: For metrics collection and visualization
  • OpenTelemetry: For distributed tracing
  • Centralized Logging: For aggregating logs from all components

Security Architecture

SyncApp implements a multi-layered security approach:

  1. Network Security: Firewalls, WAF, TLS/SSL, IP-based access control
  2. Application Security: Authentication, authorization, input validation, CSRF protection
  3. Data Security: Encryption at rest, secure connections, data masking, audit logging

Deployment Options

SyncApp supports multiple deployment architectures:

  1. Single Server: All components on one server (development/testing)
  2. Multi-Server: Dedicated servers for web, app, workers, DB, and message broker
  3. Cloud-Native: Using managed services (AWS RDS, ElastiCache, SQS, EC2/ECS)

Scaling Strategy

  1. Horizontal Scaling: Add more instances behind load balancer
  2. Vertical Scaling: Increase resources for database servers
  3. Functional Scaling: Dedicate workers to specific job types
