4.2.7 The IoE architectural approach
Cisco’s architectural approach to the IoE is organised into three functional layers. The application layer is dependent on the platform layer, which is dependent on the infrastructure layer (Table 7).
|Application layer||Platform layer||Infastructure layer|
|This layer provides automated, dynamic, application-centric responses to changing traffic and usage demands. The application layer includes the intelligence needed to improve user experiences. It allows for the integration of traditional IT apps, and the use of collaboration applications and industry-specific applications.||This refers to Cisco solutions that provide orchestration, management, and policy adjustments based on changing demands, to accelerate service delivery. It allows applications and users to receive the resources they need, when they need them, without manual or complicated IT tasks and configuration changes. The platform layer creates business agility by implementing new services and new analytical applications that can handle Big Data needs.||This layer integrates power, security, core networks, access architectures, and storage with physical and virtual resources. It includes the right mix of hardware and software across enterprise, Cloud, and service provider networks. It converges all connections, both OT and IT, into IP and accounts for Cloud computing and mobile connectivity.|
This architectural approach reflects the service models of the cloud computing model, taking advantage of software as a service (SaaS), platform as a service (PaaS), andiInfrastructure as a service (IaaS).
