Vonage use of Cloud-based Communication
•
•
Vonage’s growth strategy is focused on three strategic initiatives: Enhancing International Calling
Base, Mobile Communication Services and International Expansion
Enhancing International
and Domestic Calling Base
Mobile Communication
Services
International Expansion
Solidifying core business
through continued
penetration of international
calling and domestic base
Meeting the emerging
needs of mobile and other
“connected device” users
Two international
partnerships announced,
roll-out began in 2012
Vonage uses scalable IP-based cloud communications platforms delivering voice, messaging and
video communications worldwide leveraging
Service Provider Perspective: Real-Time Communications in a
Cloud-Based Infrastructure

Sunny-day scenario or rainy days ahead for Cloud Solutions
enabling Real-Time Communications and Services?

What is the future of RTC in the cloud, will it work, will it scale,
how are carriers doing things differently and why?

Many IP carriers and service providers are embracing the benefits
of RTC in the cloud, yet working through the many challenges
presented in their design, architectures and operations.
Key Benefits for Voice and Video over IP Service Providers

• Reduction of Infrastructure Costs and Operational Savings
• Costs of IaaS and Cloud resources continues to drop
• Cost-benefits of Data Center Deployment vs. Cloud Services
• Rapid Deployment of Services
• Resources enabled when and where – cost efficiencies
• Reachability: Globally-deployed Infrastructure
• Distribution of applications: Wide allocation helps reduce DDoS attacks
• Cloud virtual machines – hypervisor technology and performance continues
to improved making RTC possible
Service Provider Perspective: Real-Time
Communications in a Cloud-Based Infrastructure

Key Challenges for Voice and Video over IP Service Providers
• IPv4 address space in public cloud yield Network and Port Address
Translation (NAT - PAT) issues vs. private cloud
• Configuration control over firewalls, NAT, security settings and performance
• Noisy Neighbors: who are they and what is the behavior of your neighbors
in the cloud?
• Real-time communications architecture, design, and operation in the cloud effects
on bandwidth, performance, load distribution, etc.
• Lack of visibility into the cloud environment that impacts your real-time services
• Management of VM Resources
• Design and tune VMs for real-time services, RTP, RTCP, VoIP, Video, streaming
• Impact on trans-coding capability (as needed)
• Use of real-time environment security – TLS, SRTP, Encryption
• Design of SBCs as applicable to the service
• Judicious use of VMs may impact efficiency, availability, cost and performance
• Monitoring your resources in real-time (In-band vs. out-of-band capabilities)
Service Provider Perspective: Real-Time
Communications in a Cloud-Based Infrastructure

Key Challenges for Voice and Video over IP Service Providers
(continued)
• Predictability of Service with or w/o SLAs (99.0 99.999% uptime/availability)
• Operational costs may impact real-time service requirements
• Security and Data Privacy in the cloud
• Cloud Environment Governance: Policy, Legal and Regulatory
• Lawful Intercept “real-time” Design and Operation

Parting Thoughts: Service Provider Real-time Communications in
the Cloud
• Use of IPv6 Address Space will help
• Cost of VM and infrastructure will decrease
• Cloud technologies, VMs are significantly improving in performance
• Improvements in cloud architectures, bandwidth allocation/optimization for
RTC continue
Thank you!
