In fact, according to a report by Frost and Sullivan, 2012 was a landmark inflexion point in the market where North American hosted contact center revenues were greater than on premise product sales (excluding maintenance). From a market sizing perspective, the North American Hosted IP Telephony and UCC Services Market was estimated at $1.42 billion (without access) in 2013, and is expected to reach $3.91 billion in 2017 growing at a 27% CAGR. Additionally, the North American hosted contact center market was estimated at $1.76 billion in 2013 and is expected to reach $3.13 billion in 2017 growing at a 12% CAGR 1. The ability for businesses to purchase communications on a per-user, permonth basis is highly beneficial to companies facing CAPEX cost constraints and IT shortages. Hosted services offer a number of benefits such as a predictable cost structure that can be properly budgeted, the elasticity to be able to add users and add functionality quickly and easily (an example being able to scale up contact center capacity quickly for the Christmas season and then quickly scale it back down again) and the flexibility to choose only what features are needed rather than having to purchase all the current and future capabilities upfront in a dedicated on-premise system. As cloud service providers roll out mission-critical, high value communications services, many are looking to integrated full stack solutions that offer virtualized applications, compute, storage and networking which are managed and supported as a single offer. These solutions offer many values including the ability to get to market faster, simpler, more streamlined management and the ability to deliver a consistent cookie cutter set of services to all subscribers.

In a UCaaS environment the solution delivers: Administration and provisioning of services per tenant End user self-care administration Third party integration capabilities (OSS integration / APIs) In a CCaaS environment the solution delivers the added benefits of: Usage tracking and billing for Contact Centers Visual Call Flow Designer for Contact Centers Self-service IVR Support Solution Architecture The Collaboration Pod for Hosted UC and CC Services has a versatile state-ofthe-art design, making it suitable for multiple types of solutions within the same environment. It has fully resilient, connection-preserving stacks on a per customer basis. Implementation generally consists of dual Collaboration Pods hosted across two geographically separated data centers. Each stack has its own virtualized servers (or multiples thereof) for resilience in case of failure of the underlying hardware. In the case of an active application failure, the standby instance of the failed application takes over operations. The architecture of Collaboration Pod for Hosted Services allows Cloud Service Providers to implement multiple customers on a single software instance by partitioning the virtualized infrastructure and networking. This approach allows providers to leverage resources from the solution. Multiple customers connect through the session border controller and produce separate network traffic for each customer network. The CCaaS and UCaaS solutions on the Collaboration Pod allow for different tenant settings between locations. The figure below shows the Collaboration Pod integrated solution design. avaya.com 11
Endpoints The CCaaS and UCaaS solutions can support both SIP and H.323 for call processing and media-related traffic. Session Manager is the core element providing routing and connections for all SIP/H.323 entities including endpoints and agents. In a CCaaS environment specifically, combining endpoint capabilities with the power of Elite Multichannel allows contact center agents to receive and reply to work items from customers who make contact by telephone, email, web chat, or SMS/text. High Availability The Collaboration Pod has been designed from the ground up to ensure highavailability, non-stop operation. Its design incorporates both hardware redundancy and software resiliency features intended to ensure continuous operation even in the worst-case scenario. Hardware Redundancy Hardware is designed so that in the event of an individual component failure, the Collaboration Pod will continue non-stop operation. Networking equipment, connectivity and power are redundant: Redundant routers and switches Multiple Power Distribution Units (PDUs) designed for separation of power sources Redundant 1 Gig /10 Gig connections to data center routers/switches Redundant storage and high availability storage networking: Redundant 10 Gig paths to redundant networking devices Raid resilient configuration preventing data loss for drive failures Compute servers in a VMware high availability cluster: Servers leverage dual power supplies across different PDUs Raid resilient drive configuration ensuring server operation Additional redundancy options: Media gateways Session border controllers Application Level and Local Server Redundancy Local server redundancy is incorporated into the Collaboration Pod architecture to deliver application resiliency in the event of a server failure. Leveraging Avaya Aura Platform survivability features combined with VMware vcenter management features, this design provides a highly resilient solution for Avaya virtualized applications. avaya.com 12
The following scenario lays out how this solution works using an example Collaboration Pod UCaaS configuration. In this example, the system includes three servers provided and supported by Avaya running VMware vsphere. (Please note that the number of servers can vary depending on the customer situation.) Avaya virtualized applications are distributed across the servers as follows: Host 1 includes the Avaya Pod Orchestration Suite, Avaya Control Manager and vcenter to monitor all Pod components as well as the subscribers/ tenants. Host 2 supports the following Avaya Aura applications: Communication Manager (primary), Session Manager (primary), AES, Utility Services and WebLM. Host 3 includes Communication Manager (secondary), Session Manager (secondary), System Manager and Presence Services As shown in the layout, the system is designed to support Communication Manager software duplication and Session Manager active-active redundancy; the backup applications are in place on Host 3. If a failure occurs with Host 2, the primary Communication and Session Managers are lost for call processing. Since the system incorporates software duplications and active-active redundancy, the call processing is preserved by the secondary instances of these two applications in Host 3 as shown below. For the other applications beyond Communications and Session manager, VMware HA kicks in and the applications are automatically migrated from the failed host and restored to normal operation on Host 3. avaya.com 13
As shown in the final diagram below, the Collaboration Pod utilizes VMware HA to automatically restore operational instances for CM and SM whenever a switchover to a secondary new server is needed. In this example, CM and SM instances have been migrated to Host 1 restoring the applications to normal operation and application redundancy is restored. The Collaboration Pod elegantly allows Avaya Aura Platform product high availability to be fully restored after a server failure. The survivability options inherent in Avaya Aura are complemented by the system resource management features included in VMware. Geo-redundancy The Collaboration Pod architecture also supports multi-pod, geo-redundant architectures. This includes multiple data center configurations. This is possible due to high availability features inherent in both the Avaya Networking and Avaya Aura Platform products integrated into the Collaboration Pod. avaya.com 14
The Fabric-enabled Avaya Virtual Services Platform 7000 top-of-rack switch provides both high-density 10 Gbps Ethernet server connectivity as well as high-speed fabric-enabled interconnect links. This enables a transparent scaleout solution across multiple sites. Multiple Collaboration Pods and/or Extension Pods can be interconnected via the VSP 7000 s high-speed links which leverage Avaya Fabric Connect technology (based on IEEE 802.1aq Shortest Path Bridging) for scaling and resource sharing. The Avaya Fabric technology effectively transforms the Data Center network into a dynamic, self-aware utility. Instead of applications tied to a single server or rack, Fabric Connect allows the seamless transfer of workloads across geographical boundaries. It eliminates the complex provisioning models normally required to support virtual machine mobility, while helping ensure that the network remains free from configuration errors and loops. This architecture also synchronizes the network to the compute environment using Collaboration Pod integrated management tools to automate network provisioning when virtual machines migrate between physical servers. To understand how all this works together, let s look at a dual data center Collaboration Pod architecture as shown below: In this example, both data centers support Avaya Aura Platform virtualized applications within the Collaboration Pod. With the survivability features inherent in both the Avaya Aura and Avaya Networking products integrated into the Pod configuration, the example shows how redundancy can operate across geographically separate data centers. Geo-redundancy offers the ability to have backup instances of the key Avaya Aura applications not only in a separate server host cluster but in a completely separate data center, geographically removed from the main data center. The design supported by geo-redundancy adds value by offering a solution that maximizes system availability for catastrophic failures. When a single location is no longer available, this architecture will provide a backup communications solution from another Data Center across towns or across states. avaya.com 15
The figure below shows this principle, with the Collaboration Pod in Data Center 1 being the primary solution and in normal operation. If Data Center 1 experiences a failure, the survivability features of Communication Manager, Session Manager and System Manager become active in Data Center 2, restoring normal operation as shown below. The Collaboration Pod in Data Center 2 takes over management of all functions. End users can continue daily operations with the resources in Data Center 2. avaya.com 16
