PI System Connector connects PI System from OSIsoft PI System Enterprise Data Infrastructure on AWS 1 individual sites to the Roll-up PI System on AWS via Highly available and load-balanced configuration of Roll-up PI System that aggregates data from multiple PI Systems across sites. AWS Direct Connect or AWS Site-to-Site VPN. 2 Data from edge devices can be ingested via Modbus, OPC UA or MQTT into AWS IoT 12 Greengrass or with a AWS Lambda function. AWS Cloud 3 AWS IoT Greengrass sends the data from edge devices to AWS IoT Core using MQTT. An AWS IoT Core rule is triggered that invokes a Lambda Users Availability Zone 2 Availability Zone 2 function. VPC An AWS Lambda function translates data from Amazon S3 4 1 MQTT message into OSIsoft Messaging Format On- Public subnet Public subnet (OMF) and then sends it to the PI Web API which Premises posts the data to PI System. 11 AWS Site-to 5 Amazon 5 PI System data from on-premises is sent to the PI PI System Site VPN Redshift Connector Relay which posts the data to PI System. Connector 6 Elastic Load Balancing directs PI System traffic PI Connector PI Integrator for PI Vision Elastic Load PI Vision from public subnet (PI Connector Relay, PI Web AWS Direct 4 Relay Business API, PI vision and PI Integrator for Business Balancing Analytics Connect Amazon Analytics) to the PI Asset Framework (PI AF). PI Interface PI Server Kinesis 7 Highly available SQL Servers running on Amazon PI Web API EC2 instances store the metadata used by PI Vision AWS Lambda and PI AF. Both PI Collective servers (Primary PI Data Archive Amazon 8 2 Private subnet Private subnet and Secondary PI Data Archive) receive data from 6 Managed Edge Devices 8 PI Connector Relay. 10 8 Streaming for Apache 9 Microsoft Active Directory provides Windows 3 Kafka Integrated security access between PI Systems and PI AF Secondary PI is used for user authentication and authorization. AWS IoT Greengrass PI Analytics Primary PI PI AF Elastic Load Data Archive PI Analytics connects to PI AF and PI Data Archives Data Balancing 10 Archive to perform KPI and Event Frame computations.
