Overview of Cloud Exchange Networking Solutions
Four factors are changing the landscape of Wide Area Networks (WAN):
- Applications and data are fast moving to a cloud domain putting the WAN on the critical path.
- Increased adoption of Bring Your Own Device (BYOD) access from users that are outside the corporate network.
- Business continuity and disaster recovery solutions need to work across the WAN.
- Utilization of WAN resources must be optimized for cost containment.
These factors drive the following important questions:
- What WAN options does an enterprise have to ensure application and data availability when they have moved into the Cloud?
- What is the best solution to ensure user-to-application communications are delivered with expected Quality of Experience, at a reasonable cost structure?
- How can a service provider be responsive to the enterprise at the speed of Cloud-based business?
Sonus’ answer is VellOS®, our cloud exchange networking platform
VellOS represents the first platform in a new class of cloud exchange networking products that integrates private, hybrid, and public clouds, supporting distributed applications and services from enterprises and service providers, into a seamless IT environment.
As the internet and cloud-based services become critical to businesses as a means of supporting communications both in and outside of the company, it is vital to ensure their cloud deployments have optimal network connectivity. This means they need to focus on real-time management, application traffic prioritization and bandwidth utilization within their cloud deployments. Sonus’ VellOS® is a cloud exchange networking platform that provides a cost effective way for businesses to address all three of these points. Sonus’ VellOS® provides interworking with web- based portals and APIs, flexibility to orchestrate WAN connectivity on-demand, the ability to dynamically implement WAN changes based on changes in business connectivity and end-to-end visibility into the cloud exchange network bandwidth.
Business continuity is important to every business and becomes even more so as every aspect of the business moves into the cloud. Businesses must ensure access to cloud-based applications and data centers even during disaster as even a temporary lapse in access could drive consumers to a competitor. What Sonus’ VellOS® has to offer to businesses is the means to ensure all information is not only backed up but accessible during times of disaster, minimizing the negative impact on business operations. Sonus’ VellOS® provides interworking with web based portals and APIs, flexibility to orchestrate WAN connectivity on-demand, the ability to dynamically implement WAN changes based on changes in business connectivity and end-to-end visibility into the cloud exchange network bandwidth.
Applications such as Microsoft Skype for Business, which deliver real-time unified communications have several specific requirements. These include low latency, jitter and packet loss. When these real-time communication applications are delivered across a WAN network, and in particular when they are provided from a cloud domain it can be challenging to meet these demands. The solution to this problem is to implement a method which ensures bandwidth allocation and packet prioritization across the WAN, based on application policies. This is exactly what Sonus’ VellOS® provides to businesses through enabling interworking between VellOS and Microsoft’s Skype for Business UC SDN API.
Security has changed drastically as businesses make the move to cloud-based services. Businesses can no longer rely on the same solutions they used to secure traffic across the corporate LAN. Now traffic is routed across WANs to connect users to applications and data that are now hosted in remote data centers. One approach used to ensure traffic security is to rely on the application itself for security. This works well when security is an integral part of an application’s design and implementation. However, in many cases this doesn’t work because sufficient security is not built into applications and they rely on network solutions security. Sonus VellOS® plays a key role to augment network layer security through association with security policy management enabling a multi-layered security solution.
