In our previous blog, we began our exploration of how Fast IT will transform the role of the IT organization — enabling it to drive innovation in unprecedented ways for the business. And to do so amid the rapid disruption of the Internet of Everything (IoE) economy.
Specifically, we examined the role of Fast IT in simplifying complex, cumbersome infrastructure. And how this added agility will open the door to faster provisioning of enterprise apps; a new dimension in value derived from cloud; and a true place for IT as a service orchestrator and trusted partner for the business.
But Fast IT transformation extends further still, enabling expansive and dynamic new capabilities through analytics and security; driving the cultural change that must accompany infrastructure change; and liberating the IT organization through dividends in cost and time savings.

Physical Infrastructure Layer
The physical infrastructure layer is where the physical resources reside. This includes equipment typically used in a data center such as network devices (switches, routers, firewalls, and load balancers), computing resources, storage and facilities. Physical infrastructure products and the connectivity to the cloud, customer networks, partners and cloud brokers are secured in this layer.
Virtual Infrastructure Layer
The main purpose of this layer is to abstract the underlying physical resources into pools of logical resources with attributes and service assurance parameters. In addition, it greatly simplifies management processes, accelerates service delivery to market, and reduces operating expenses. Simplicity of provisioning and management along with security can be obtained by creating many logical networks from one physical network. The physical infrastructure layer is virtualized using various methods (hypervisor technology, Application Centric Networks, etc.) into a virtualized infrastructure layer. This is analogous to creating VLANs within a physical LAN. The Resource Abstraction and Control functionality in this layer views the physical layer in a more holistic fashion by allowing the orchestration, network and security controllers to enforce appropriate policies to the traffic and the underlying network infrastructure.
With 1.1 million units in the marketplace, Cisco is far and away the market’s #1 provider of 802.11ac wireless infrastructure with the industry’s broadest and most powerful product offerings for the Enterprise, Service Providers, Small Medium Business and exploding Cloud market spaces.
With the 3700 Series, Access Point is leading the charge as the fast ramping Access Point in Cisco’s history.
Providing up to 3 times the performance of legacy 802.11n deployments, 802.11ac provides the performance and scale foundation for companies as they move to an all-wireless and -mobile working culture in their day-to-day business operations.

The following figure shows a simplified view of the Cisco CSA. It has five horizontal layers: Physical Infrastructure layer, Virtualized Infrastructure layer, Services layer, Service Management and Automation layer, and App/portal layer. Supporting each layer from top-to-bottom, there are three vertical layers: ITSM/ITIL services layer services enablement, Security layer for providing security across each of the horizontal layers, and Cisco Intellectual and domain management layer for providing Cisco best practices at each of the horizontal layers.
This CSA is a logically layered architecture (LLA), with each layer providing a distinct function. The model is designed in a hierarchical fashion with devices and facilities at the bottom, customer interactions at the top, and various required functionalities in the middle layers. The key to this model is the abstraction of each layer into software-defined components with standardized interfaces. Similar to other LLA models such as ITU-T TMN (Telecommunications Management Network), each horizontal layer supports the layer above in performing its business functions.
CSA Layered Approach
The interaction between various layers is through abstraction, orchestration, and API’s. The customers’ requests are processed from the top layer where orchestration fulfills the various components and provisions into the infrastructure using the API’s between the layers. Similarly, the Read More »
