Indus­try 4.0 is already trans­form­ing man­u­fac­tur­ing, but the real pow­er lies in clos­ing the data gap between the fac­to­ry floor’s oper­a­tional tech­nol­o­gy (OT) and the enterprise’s IT sys­tems. This chal­lenge requires a robust, mod­ern foundation. 

That’s where the Red Hat and SAP part­ner­ship deliv­ers. We’ve cre­at­ed a com­plete, secure, and scal­able frame­work — the ​“dig­i­tal thread” — that ensures a con­tin­u­ous, reli­able flow of data from the small­est machine sen­sor, man­aged by Red Hat’s edge solu­tions, all the way to the exec­u­tive lev­el. Red Hat’s open hybrid cloud tech­nolo­gies pro­vide the con­sis­tent, rock-sol­id plat­form required to make intel­li­gent man­u­fac­tur­ing a reality. 

Here is a look at the pow­er­ful, three-tier archi­tec­ture, built on Red Hat’s open-source lead­er­ship, that enables this trans­for­ma­tion. The 3‑Tier Archi­tec­ture: Pow­ered by Red Hat’s Open Hybrid Cloud.

Red Hat pro­vides the essen­tial, uni­fied infra­struc­ture lay­er across all three tiers: 

Tier 1: The Device & Plant Edge (The Shop Floor) 

This tier demands min­i­mal resource con­sump­tion and max­i­mum sta­bil­i­ty. We lever­age Red Hat Device Edge/​MicroShift—the ultra-light­weight, Kuber­netes-based solu­tion — for local, real-time pro­cess­ing and basic AI, such as imme­di­ate defect check­ing. This foun­da­tion com­mu­ni­cates seam­less­ly using indus­tri­al pro­to­cols like OPC UA and MQTT. 

Tier 2: The Near Edge / Facil­i­ty (The Plant Con­trol Hub) 

This crit­i­cal mid­dle lay­er is the plant’s secure, con­tainer­ized con­trol hub. It is pow­ered by Red Hat Open­Shift, the indus­try-lead­ing enter­prise Kuber­netes plat­form. Open­Shift hosts essen­tial plant soft­ware like MES and runs the cen­tral com­po­nent, the SAP BTP Edge Inte­gra­tion Cell (EIC). By run­ning on Open­Shift, the EIC gains the sta­bil­i­ty and ​“store-and-for­ward” resilience need­ed to guar­an­tee data is nev­er lost, even dur­ing net­work outages. 

Tier 3: Enter­prise / Cloud Core (Head­quar­ters)

This is the cen­tral hub for core busi­ness appli­ca­tions like SAP S/4HANA. Red Hat Open­Shift enables this tier to oper­ate as a true hybrid cloud core, ensur­ing con­sis­ten­cy and porta­bil­i­ty whether it runs on-premis­es or across major cloud providers (Azure, AWS, GCP). This open, flex­i­ble envi­ron­ment sup­ports high-lev­el AI and ana­lyt­ics ser­vices like SAP BTP Datasphere. 

Red Hat’s Tech­nolo­gies Dri­ving the Dig­i­tal Thread 

The entire frame­work is under­pinned by Red Hat’s enter­prise open-source plat­forms, ensur­ing con­sis­ten­cy and secu­ri­ty from the small­est device to the largest cloud:

• Red Hat Open­Shift: This is the con­sis­tent, enter­prise-grade con­tain­er plat­form that hosts all appli­ca­tions across the Near Edge (Tier 2) and the Cloud Core (Tier 3). Open­Shift pro­vides the reli­a­bil­i­ty, secu­ri­ty, and scal­a­bil­i­ty nec­es­sary for mis­sion-crit­i­cal indus­tri­al workloads. 
• Red Hat Device Edge/​MicroShift: The light­weight, hard­ened Kuber­netes dis­tri­b­u­tion that brings the pow­er of con­tain­ers to the deep edge of the shop floor. 
• SAP EIC (Edge Inte­gra­tion Cell): This vital con­nec­tor runs secure­ly on the Red Hat Open­Shift plat­form, lever­ag­ing its robust con­tain­er secu­ri­ty and man­age­ment capa­bil­i­ties to link oper­a­tional data from Tier 1 to the cloud ser­vices in Tier 3. 
• SAP S/4HANA & SAP BTP: SAP’s core busi­ness and cloud ser­vices are deployed and man­aged effi­cient­ly across the Open­Shift-pow­ered hybrid environment.

Real-World Impact: The Use Cas­es That Trans­form Operations

The inte­gra­tion of Red Hat’s plat­form with SAP’s busi­ness appli­ca­tions cre­ates pow­er­ful, trans­for­ma­tive use cases: 

• Pre­dic­tive Main­te­nance: Real-time sen­sor data is processed by edge AI on Red Hat Device Edge, spot­ting fail­ures and auto­mat­i­cal­ly trig­ger­ing a work order in SAP EAM/PM at headquarters. 
• AI-Dri­ven Qual­i­ty: Vision AI, pow­ered by con­tain­ers run­ning secure­ly on a Red Hat plat­form, detects prod­uct defects on the shop floor in real-time. 
• Trace­abil­i­ty: Com­po­nent data is tracked across all tiers, secured and man­aged by the Red Hat infra­struc­ture, pro­vid­ing end-to-end visibility. 
• Sus­tain­abil­i­ty: IoT data on ener­gy con­sump­tion is reli­ably col­lect­ed and rout­ed via the Red Hat/​SAP EIC back­bone for accu­rate ESG reporting.
