Distributed Cluster Architecture for Unlimited Horizontal Scaling
JitAI enables seamless scaling from single-node deployments to large-scale enterprise cluster architectures through hierarchical management of teams, nodes, runtime environments, and applications, delivering comprehensive resource scheduling and load balancing capabilities.
Understanding the four-layer architecture model
Teams can encompass multiple nodes, with each node participating in multiple runtime environments. Runtime environments can span multiple nodes and host multiple application deployments.
Designing enterprise cluster deployment architecture
Implementing typical deployment topology
Teamanizing multi-dimensional environment division
Runtime environments support flexible organization across multiple dimensions to accommodate complex enterprise deployment requirements:
| Classification Dimension | Environment Examples | Use Cases |
|---|---|---|
| By Stage | Development, Testing, Production | Standard software development process |
| By Business | E-commerce, Payment, Logistics | Business module isolation |
| By Customer | Customer A, Customer B, Demo | Multi-tenant deployment |
| By Purpose | Performance Testing, Security Testing | Specialized testing requirements |
Configuring entry address strategies
Entry Point Configuration Examples:
| Runtime Environment | Primary Entry Point | Backup Entry Point | Port |
|---|---|---|---|
| Development Environment | dev.company.com | dev2.company.com | :8080 |
| Testing Environment | test.company.com | staging.company.com | :8081 |
| Production Environment | company.com | backup.company.com | :80 |
| Customer A Environment | a.company.com | a1.company.com | :8082 |
| Demo Environment | demo.company.com | - | :8083 |
Implementing cluster scaling strategies
Deploying horizontal scaling modes
Node-level scaling
- Add physical or virtual nodes to expand cluster capacity
- Enable automatic load balancing and intelligent request distribution
- Support cross-regional node deployment for geographic redundancy
Environment-level scaling
- Create new runtime environments on existing infrastructure
- Enable dynamic environment migration and seamless replication
- Achieve business isolation and optimize resource utilization
Application-level scaling
- Deploy identical applications across multiple environments
- Support version parallelism and canary release strategies
- Ensure high availability and comprehensive disaster recovery
Implementing load balancing and fault tolerance
Multi-node load balancing
- Intelligent request routing and dynamic distribution
- Continuous node health monitoring and automatic failover
- Advanced weight configuration and granular traffic control
Environment-level fault tolerance
- Complete fault isolation between runtime environments
- Proactive fault detection and automated recovery systems
- Robust data backup and real-time synchronization mechanisms
Understanding architecture constraints and best practices
Managing version constraints
| Scenario | Rule | Status | Description |
|---|---|---|---|
| Different applications in same environment | Any version combination | ✅ Allowed | E.g.: Development environment deploys Application A v1.0 and Application B v2.1 simultaneously |
| Same application in different environments | Different version deployment | ✅ Allowed | E.g.: Development environment deploys Application A v1.0, production environment deploys Application A v1.1 |
| Same application in same environment | Multiple versions coexist | ❌ Prohibited | Only one version of the same application can exist in the same environment |
Configuring network access constraints
| Operation Type | Rule Description | Status | Example |
|---|---|---|---|
| Multi-address configuration | Configure multiple entries for one environment | ✅ Allowed | Production environment: app.com + backup.app.com |
| Dynamic modification | Modify environment entry at runtime | ✅ Allowed | Temporarily switch domain names or add backup entries |
| Address sharing | Multiple environments share the same entry | ❌ Prohibited | Two environments cannot use test.com simultaneously |
| Conflict detection | System automatically detects conflicts | 🔍 Automatic | Real-time conflict checking and prompting during configuration |
Following deployment best practices
Version management
- Utilize distinct environments for comprehensive application version testing
- Achieve seamless application version upgrades through strategic environment switching
- Establish clear version naming conventions and standardized release specifications
Network configuration
- Implement meaningful domain prefixes for clear environment identification
- Configure redundant entry addresses for critical production environments
- Minimize modifications to production environment entry addresses for stability
Resource planning
- Strategically allocate node resources based on comprehensive business load analysis
- Conduct regular evaluations and proactive adjustments of environment configurations
