Typical Infohub Architectures
Flow is a modular system that can be deployed in a variety of architectures (as below) or in a combination of these. An instance of the Infohub is created per operational site. Multiple Infohub instances can be linked using a Tier 2 Infohub instance, typically at enterprise.
Standard Site Deployment
- Single on-premise Flow Infohub Server including a local Microsoft SQL Server
- Connected to multiple data sources including PLCs, Historians, and SQL databases
- Workstations running Flow Config and Visualization via browsers
Deployed Data Sources
- Connected to deployed data sources to ensure collection is local to source
- Deployed Data Sources require the Flow Bootstrap to be installed on the respective servers
Distributed
- Multiple Flow Servers to distribute computing load
- Dedicated Microsoft SQL Server
Edge and Cloud
- Flow Server deployed to cloud provider (AWS, Azure, etc.)
- Data Sources deployed to the edge (on-premise) using a single outbound connection
Enterprise Deployment With Tier 2
- Enterprise rollup from multiple Tier 1 (Site) Infohub Systems to one or more Tier 2 (Enterprise) Infohub Systems
- Ideal for cross-site benchmarking, comparison, and planning
- Central model template management
