Cisco Preferred Architectures provide tested and recommended deployment models for specific market segments
based on common use cases. They incorporate a subset of products from the Cisco Collaboration portfolio that is
best suited for the targeted market segment and defined use cases. These deployment models are prescriptive, out-
of-the-box, and built to scale with an organization as its business needs change. This prescriptive approach simplifies
the integration of multiple system-level components and enables an organization to select the deployment model that
best addresses its business needs.
About This Guide
This document provides a high-level overview of the Preferred Architecture (PA) for on-premises deployments of
Cisco Collaboration release 15. It is intended for use in pre-sales discussions and decision making by:
•
Sales teams that design and sell collaboration solutions.
•
Customers and sales teams who want to understand the overall collaboration architecture, its components, and
general design best practices.
This guide simplifies the design and sales process by:
•
Recommending products in the Cisco Collaboration portfolio that are best suited for on-premises deployments
and that provide appropriate feature sets for those deployments.
•
Detailing a collaboration architecture and identifying general best practices for deploying in enterprise
organizations.
This guide describes the Cisco Collaboration on-premises Preferred Architecture for Enterprise collaboration —
Deployments of more than 1,000 users on a variety of platforms. In this case, on-premises means on-premises
infrastructure and on-premises applications including collaboration. This architecture does not preclude cloud
services such as push notifications, Cisco Smart Software licensing, and Cloud Connected UC, however, most
components and services are delivered from on-premises. While this architecture is not intended for “air-gapped”
deployments, it can be modified to reduce dependencies on cloud services. For example, permanent or specific
license reservations (PLR or SLR) can be used eliminating the need for connectivity to the Cisco Smart Software
licensing service.
For hybrid and cloud collaboration deployments where cloud services and applications including Webex and the
Webex App are included, refer to the hybrid Preferred Architecture documentation and alternative design guides
available on the Cisco Collaboration Preferred Architectures site.
Readers of this guide should have a general knowledge of Cisco Voice, Video, and Collaboration products and a basic
understanding of how to deploy these products. For detailed information about configuring, deploying, and
implementing this architecture, consult the Cisco Validated Design (CVD) guides listed in the next section on
Documentation for Cisco Collaboration On-Premises Preferred Architecture.
