Architecture

The Roltek architecture is designed to provide a secure, scalable, and flexible IoT infrastructure that supports diverse deployment scenarios — from small installations to large, multi-site enterprise environments.

The architecture follows a modular approach, allowing each layer to scale and operate independently.

High-Level Architecture

A typical Roltek deployment consists of the following layers:

1. Devices & Sensors
2. Gateways & Edge Layer
3. Communication Layer
4. Cloud Platform
5. Applications & Integrations

Each layer plays a specific role in the data lifecycle.

Devices & Sensors Layer

This layer includes all field-level devices responsible for collecting data.

• Sensors, meters, controllers, and actuators
• Industrial and commercial-grade devices
• Support for various communication interfaces

Devices generate raw data and send it to the gateway or directly to the platform, depending on the deployment model.

Gateways & Edge Layer

Gateways act as a bridge between field devices and the cloud.

Key responsibilities include:

• Aggregating data from multiple devices
• Performing edge processing and filtering
• Managing local buffering during connectivity loss
• Ensuring secure data transmission

The edge layer enables reliable operation even in unstable network conditions.

Communication Layer

The communication layer ensures reliable and secure data transfer.

• Standard IoT protocols (MQTT, HTTP, etc.)
• Encrypted communication channels
• Configurable data transmission intervals

This layer abstracts network complexity from upper layers.

Cloud Platform Layer

The cloud layer is the core of the Roltek ecosystem.

• Device and data management
• Data storage and processing
• Alerting and rule engines
• User and access management

The platform is designed for high availability and horizontal scalability.

Applications & Integrations Layer

This layer provides access to data and insights.

• Web dashboards and visualizations
• APIs for external system integration
• Webhooks and event-based communication
• Reporting and data export

It enables seamless integration with enterprise systems.

Data Flow Overview

A typical data flow in the Roltek architecture follows these steps:

1. Devices collect data from the field
2. Data is sent to the gateway or directly to the cloud
3. Edge processing and buffering (if enabled)
4. Secure data transmission to the platform
5. Data storage, processing, and visualization
6. Alerts and integrations are triggered when conditions are met

Deployment Scenarios

Roltek architecture supports multiple deployment scenarios:

• Cloud-Centric
  Devices communicate directly with the cloud platform.

• Edge-Centric
  Gateways perform local processing and decision-making.

• Hybrid
  Combination of cloud and edge processing.

Scalability & Reliability

The architecture is built to support:

• Large numbers of devices
• High data throughput
• Multi-site deployments
• Fault tolerance and redundancy

Each layer can scale independently to meet system demands.

Security by Design

Security is embedded into every architectural layer.

• Secure device identity and authentication
• Encrypted communication channels
• Controlled access between layers
• Data isolation and privacy protection
