Topology Selection Guide
When Should Topology 1 (Test/PoC) Be Used?
When Should Topology 1 (Test/PoC) Be Used?
Usage Scenarios:
- Proof of Concept (POC) projects
- Development and test environments
- Low-traffic applications (< 500K requests/day)
- Quick installation requirements
- Limited resources and budget
- For training and learning purposes
- Lowest resource requirements
- Quick installation
- Low cost
- Simple management
- Single point of failure risk
- No high availability
- Not suitable for production
- Limited scalability
When Should Topology 2 (Professional) Be Used?
When Should Topology 2 (Professional) Be Used?
Usage Scenarios:
- Medium-scale production environments
- Medium-traffic applications (500K - 3M requests/day)
- Basic high availability requirements
- Situations requiring budget optimization
- Enterprise applications
- Load balancing between worker nodes
- Medium-level resource requirements
- Suitable for production
- Flexible scaling
- Limited high availability
- Database single point of failure risk
- No geographic distribution
When Should Topology 3 (High Availability) Be Used?
When Should Topology 3 (High Availability) Be Used?
Usage Scenarios:
- Critical production environments
- High-traffic applications (> 3M requests/day)
- High availability requirements (%99.9+ uptime)
- Critical business processes
- Data security and replication requirements
- High availability (%99.9+)
- Automatic failover
- Data replication
- Load balancing
- Zero-downtime updates
- High resource requirements
- Complex installation
- High cost
- Cluster management requirements
Scaling Strategies
Vertical Scaling
Increasing single server performance:- CPU and RAM increase
- Disk capacity increase
- Network bandwidth increase
Horizontal Scaling
Increasing server count:- Increasing worker node count
- Increasing MongoDB replica set node count
- Increasing Elasticsearch cluster node count
