Solution Architecture & Design
What We Deliver
KEANT Technologies designs and delivers mission-critical, enterprise-grade SaaS platforms that provide unified, real-time monitoring and operational control across complex, multi-zone infrastructure. Our architecture practice covers the full spectrum — from initial system design and technology selection through to production deployment and long-term maintainability.
1. System Overview
Our solution architecture practice is built around designing platforms that are scalable, secure, and operationally robust from day one. We engage clients at the earliest stage of product definition, translating complex operational requirements into clean, layered architectures that can evolve alongside the business.
A typical KEANT-architected platform delivers:
- Real-time monitoring and control across large-scale, distributed asset networks
- Role-aware interfaces that surface the right information and controls to the right users
- Resilient integration layers connecting heterogeneous devices, protocols, and data sources
- Horizontally scalable backend services designed for high-availability production environments
- Comprehensive audit trails and fault management pipelines for operational accountability
2. Architectural Layers
Our platforms follow a layered, service-oriented architecture with clear separation of concerns across presentation, business logic, integration, and data tiers:
| Layer | Responsibility & Capability |
|---|---|
| Presentation Layer | Web-based responsive UI with 20+ functional screens — map-based dashboards, zone drill-downs, device summary tiles, and real-time signal panels. Role-aware rendering ensures administrators see controls unavailable to view-only operators. |
| Application Layer | Business logic services handling session management, role-based access control (RBAC), alert orchestration, notification dispatch, fault lifecycle management, and audit logging. REST and WebSocket APIs bridge frontend and backend. |
| Integration Layer | Protocol adapters connect field devices and controllers over industry-standard and proprietary interfaces. A device abstraction layer normalises signals from heterogeneous hardware into a unified data model consumed by higher layers. |
| Data Layer | Time-series store for live telemetry; relational database for device registry, user management, audit trails, and configuration; in-memory cache for sub-second dashboard refresh. Fault events are persisted with full signal snapshots for post-incident analysis. |
3. Key Functional Modules
Our platform blueprints are modular by design. Functional capability is organized into well-defined modules that can be composed, extended, or replaced independently:
Monitoring & Dashboard
- Map-based landing screen with selectable operational zones
- Colour-coded device tiles for instant health classification: Running, Fault, Stopped, Maintenance, Emergency
- Summary screens per device type with live status overlays
- Device detail panels: real-time signal monitoring, directional status, door state, load, brake and emergency signals
- Fault-focused operator views with show/hide error toggle
Control & Operations
- Permission-gated control actions enforced at API and UI layer
- Zone-targeted announcement and broadcast module with predefined and custom message support
- Operational mode management for emergency, maintenance and out-of-service states
- Non-networked device tracking with dedicated summary screens and offline indication
Security & Access Control
- Encrypted authentication with session-bound tokens and secure password recovery
- Role-Based Access Control (RBAC) — Administrator, Operator, Viewer — enforced at API and UI layer
- Admin panel for user provisioning, role assignment, device registration and system configuration
- Immutable audit trail of all control actions, logins and configuration changes
Alerting & Notifications
- Real-time notification engine pushing fault events to the operator interface immediately
- Fault categorisation with drill-down into error subcategories for root-cause identification
- Emergency state escalation pipeline with operator acknowledgement workflow
- Communication status monitoring to detect offline or unreachable field units
4. Non-Functional Characteristics
Every platform we architect is held to rigorous non-functional standards from the outset — not retrofitted after development:
| Availability | Designed for 24×7 critical operations; high-availability deployment with redundant services and no planned downtime windows |
| Scalability | Modular zone-based architecture supports addition of new operational zones and device types without core redesign |
| Security | End-to-end encrypted communications; RBAC enforced at every API endpoint; no unauthenticated surface area exposed |
| Usability | Operator-centric UX with map-first navigation and single-click drill-down from zone to device to signal level |
| Maintainability | Centralised admin panel for device and user management; fault logs exportable for maintenance scheduling and analysis |
| Performance | In-memory caching ensures sub-second dashboard refresh; WebSocket channels deliver live signal updates without polling overhead |
