CloudSuite Industrial Multi-Tenant Architecture Guide
CloudSuite Industrial (CSI) multi-tenant deployments run on Infor's shared AWS infrastructure where multiple customer tenants share compute, storage, and database layers with logical isolation. Understanding the MT architecture is critical for architects evaluating cloud migration from on-premise SyteLine, as it dictates customization boundaries, upgrade timelines, and integration patterns. This guide covers the full MT architecture stack from network isolation to tenant-level configuration.
Multi-Tenant Infrastructure and Isolation Model
In the CSI MT model, Infor manages the underlying AWS infrastructure including EC2 instances, RDS database clusters, and S3 storage buckets. Each tenant receives a logically isolated database schema within a shared RDS Aurora instance, with row-level security enforced through tenant ID columns across all tables. Network isolation uses AWS VPCs with tenant-specific security groups, and application-layer isolation is enforced through Infor OS authentication tokens that bind every API call to a specific tenant context.
- Shared RDS Aurora PostgreSQL clusters with tenant-specific schemas and row-level security policies
- AWS VPC isolation with dedicated security groups per tenant preventing cross-tenant network access
- Infor OS OAuth2 tokens encode tenant ID ensuring application-layer request isolation
- Shared Kubernetes pods for CSI application tier with tenant routing via Infor ION API Gateway
- Automated backup isolation ensures tenant data is recoverable independently from shared snapshots
Upgrade Cadence and Customization Boundaries
Multi-tenant CSI follows Infor's mandatory upgrade cadence, typically receiving quarterly feature updates and monthly security patches applied across all tenants simultaneously. This means customizations must conform to Infor's extensibility framework rather than core code modifications. Approved extension points include Mongoose IDO extensions, user-defined fields (UDFs) on standard forms, ION API event handlers, and Infor OS Homepages widgets. Direct database modifications, stored procedure overrides, and assembly replacements are prohibited in MT.
- Quarterly feature releases applied to all tenants with 30-day advance notification via Infor Concierge
- Mongoose IDO extensions (.idoext files) and custom IDOs deployed through the CSI Extension Manager
- User-Defined Fields (UDFs) added via the Form Extensions framework without core form modification
- ION BOD event subscriptions for custom business logic triggered by standard CSI transactions
- No direct SQL access to tenant schema; all data operations must route through IDO layer or ION APIs
Scalability and Performance Considerations
MT environments auto-scale application pods based on tenant load metrics monitored through Infor OS CloudOps dashboards. Database performance is governed by shared RDS instance sizing with per-tenant IOPS throttling to prevent noisy-neighbor effects. Architects should evaluate transaction volume, concurrent user counts, and batch processing windows against Infor's published MT performance tiers (Standard, Enhanced, Premium) which determine allocated compute shares and database connection pool limits.
- Auto-scaling Kubernetes pods respond to CPU and memory thresholds within 2-5 minutes under load spikes
- Per-tenant IOPS throttling at the Aurora level prevents one tenant from degrading shared database performance
- Three MT performance tiers: Standard (50 users), Enhanced (200 users), Premium (500+ users) with distinct SLAs
- Batch processing windows (MRP, APS planning) must be scheduled through Infor Process Automation to avoid contention
- CloudOps monitoring via Infor OS Portal provides real-time tenant health metrics and resource consumption dashboards
