Virtualized Platforms, Real Benefits

 Thanks to its 100% software model, StreamWIDE application servers can be deployed with equal performances and reliability whether on a physical server or on a virtual machine. As a result, operators get access to virtualization benefits that were initially expected only for the IT environment.

Virtualization benefits applied to network operators 

• Faster application deployment 
• Savings on hardware resources & maintenance  
• Savings on hardware redundancy mechanisms (redundancy N+1)
• Energy savings
• Lower footprint
• Improved scalability 
• Streamlined testing and trials processes

Most operators will choose to run their virtualized applications within the boundaries of a “private cloud”, where physical machines belong to the network and a pool of applications are running simultaneously on virtualized servers. However, different approaches may be considered, including the following use cases:

Typical Use Cases: 

• Private Cloud for multi-VAS architecture: Different VAS share the same hardware infrastructure. Servers are virtualized which enables related services to seamlessly request more capacity whenever they experience traffic surge. 
• Public Cloud for VAS peaks management: VAS liable to experience traffic peaks are duplicated within a public cloud environment. Whenever traffic is stable, public cloud is remains inactive and costs stay close to zero; at peak occurrences, traffic is redirected to the public cloud. Service downtime is avoided and on-premise infrastructure is sized according to average traffic levels. 
• Infrastructure virtualization for cost-savvy operators: Tier 3 and Tier4 operators can now consider deploying non-critical VAS into public cloud without investing into new hardware.
