Hybrid architecture commonly refers to a system design that combines two or more computing environments within one overall solution. In manufacturing, this usually means some applications, data, or control functions remain on-premises or close to the shop floor, while other functions run in the cloud or in enterprise IT platforms.
This model is common where plants need low-latency execution, equipment connectivity, or local resiliency, but also want centralized analytics, planning, reporting, or multi-site coordination. For example, an MES or edge layer may manage real-time production events locally, while ERP, data warehousing, or advanced analytics operate in a cloud environment.
Hybrid architecture should not be confused with a single system that is merely accessible remotely. The term describes how the solution is deployed and integrated across environments, not just where users log in. It also differs from a pure cloud or pure on-premises architecture, where most components run in only one environment.
In industrial systems, the term often matters in discussions about integration, security boundaries, data flows, validation scope, and system ownership between OT and IT teams. The exact split varies by use case, but the core idea is a deliberate mix of local and centralized platforms working together.
