On-premise local historian

a single factry historian instance runs locally within the production site, collecting and storing data close to the machines it can't be more simple it is a straightforward setup most common in single site companies, or when the focus is on reliable local data collection without the need to share across multiple plants when it’s used for standalone factories without a corporate wide historian strategy when production data must stay entirely on premise (e g due to regulation, it policies, or latency constraints) in cases where local operators, engineers and managers need fast, direct access to process data as a first step towards digitalisation before scaling to multi site or cloud architectures architecture factry historian runs on a server or virtual machine inside the plant network collectors interface directly with plcs, scada, or other ot data sources all data is written and stored locally, there is no dependency on external networks dashboards, reporting, and apis are served directly from this local instance functions used collectors buffer data locally and write it into the on premise historian database users manage configuration and access dashboards directly from the same server \[optional] integrations with local mes, erp or lab systems can be made on site benefits the site is not reliant on internet or wan connectivity low latency access to live and historical data simple to manage one installation, one site, one team sensitive process data never leaves the factory network good entry point for companies starting their industry 4 0 journey considerations scaling is limited to the capacity of the local server (storage, cpu, redundancy) requires on site it/ot support for maintenance, backups and upgrades no built in sharing of data across sites, each historian remains an island summary a local on premise historian deployment simple, self contained, and reliable ideal for single site factories or as a first step before scaling to a central historian (hub and spoke) deployment docid\ k dhagxcrdxahjcsmeknr or multi tier historian deployment docid 9kahor 4wzawyrmu8nxml architectures
