We unify fragmented operational data inside an operator into a trusted operational reality. This data foundation then enables governed sharing and coordination of actions across organizations. > Please reach out to **[contact@nexalis.io](mailto:contact@nexalis.io)** to get access to **Nexalis Agent** and create your **Nexalis Cloud environment**. *** ## 📊 Nexalis Platform Overview The diagram below illustrates how **Nexalis Agent** and **Nexalis Cloud** work together to create an open, secure, and interoperable industrial data platform: Nexalis Platform *** ## 🌐 Nexalis Cloud **Nexalis Cloud** is a secure, scalable environment that ingests and standardizes industrial signals into a shared operational reality, then governs how that reality is shared across stakeholders—enabling cross-organization coordination and applications on top. * **High-frequency ingestion**: Second-level (≈1s) time-series data. * **Near real-time availability**: Data is available via API within \~5 seconds from extraction at the Nexalis Agent. * **Data contextualization**: AI Agent that unifies complex, proprietary vendor-specific data into a unified model; this output is what Nexalis calls **Standardized data**. * **Zero-touch Onboarding**: Automation of Nexalis Agent deployments * **Data Compute & Storage**: Computes and stores raw and standardized data. * **Catalog / Trending / Events**: UI to visualize and analyze data. * **Sharing Raw & Aggregated Data**: Shares data to any applications and environments (i.e., lakehouse providers, ISVs, and custom applications) * **Security**: Encryption at rest and in transit, role-based access control and regular audits. * **Business Insight Copilot**: AI Agent answering prompts on industrial data processed by Nexalis. *** ## 🏠 Nexalis Agent The **Nexalis Agent** is the edge software that ensures reliable, real-time data flow from on-premise and remote assets to the cloud. * **Flexible Deployment**: Available on Linux, Docker, or Windows; VM, on-prem hardware, or deployed remotely in the cloud. * **Data Collection**: Connects to industrial devices with protocols such as Modbus, OPC UA, DNP3, OPC XML DA, etc. * **Automated Data Flow**: Configure automated data streaming by time intervals or value changes, with built-in support to compute data averages (e.g., 5-minute averages). * **Real-Time**: Streams industrial data in real time for immediate insights. * **Reliability**: On-disk buffering prevents data loss during outages or when connectivity to the cloud is interrupted. * **Rapid Onboarding**: Connect your data to the cloud in minutes with no complex integration thanks to our unique **EL(T) mechanism — Extract, Load, (Transform) —**; **Extracts** data from industrial systems, **Loads** it into **Nexalis Cloud**, and only then applies data **Transformations** as needed. *** ## 📚 Next Steps * Explore how to connect and consume your industrial data from **Nexalis Cloud** → [Nexalis Cloud Documentation](./nexalis-cloud/introduction) * Learn how to deploy and configure the **Nexalis Agent** → [Nexalis Agent Documentation](./nexalis-agent/introduction)
