Driving Industry 4.0 at Distributed Edges with Cloud Orchestration
at the edge . This includes lifecycle management and operation of applications at decentralized edge nodes from the cloud and will be detailed in the next section . The balance between standardization , ease of deployment as well as individualization reduce cost and simplifies custom edge applications development . This balance counts as one of the innovations provided by the solutions that are elaborated below .
Fig
. 4 - Edge computing architecture for mission critical execution of distributed manufacturing processes on the edge [ 20 ] [ 21 ]. Following these tenets , Figure 4 proposes an architecture and its components ( business applications ) based on [ 20 ] [ 21 ] that are allocated in the cloud and on the edge layer . Note that this architecture can be customized for specific needs and available resources .
The cloud layer contains business solutions , applications and services enabling centralized management and operation of the underlying edge nodes . The business applications and services run natively in containers on Kubernetes clusters . Modules of the architecture in this layer are :
• S / 4 HANA Cloud : Intelligent Enterprise applications such as ERP system and database .
• Business Technology Platform ( BTP ): provides the runtime based on Cloud Foundry or Gardener [ 22 ] [ 23 ] for the business applications , APIs for interoperability and extensions , data models , process models for integration and workflow contents . [ 17 ]
• Edge Lifecycle Management Orchestrator ( ELMO ): standardized channel to provide lifecycle management of business applications and services from the cloud to the edge .
• Digital Manufacturing Cloud ( DMC ): manufacturing execution system ( MES ) deployed in the cloud providing a set of business applications and services to execute manufacturing
