Recommended reading: Pros of Premise-Based UC; How SD WANs Benefit Enterprise Voice

Today, we’d like to highlight some recent insights on unified communications (UC) from Gary Audin at Delphi Inc. as he discusses the pros and cons of cloud-based UC solutions. In a second piece, Daniel Teichman a Senior Product Marketing Manager at Sonus Networks, writes about the real-time service quality implications when deploying enterprise voice services using SD WAN.

In his note about Unified Communication (UC) in the cloud, Audin offers a dozen reasons organizations may want to stay with an on-premises system. Audin’s analysis also offers a matrix that addresses the features, pros, and cons of a hybrid solution that incorporates both premise-based and cloud systems.

He concludes that “one of the most common reasons for not adopting a cloud service is security. This is especially true for regulated vertical markets like healthcare, financial services, and some government operations.” He adds that “another common decision-making factor when choosing IT equipment is control. If the enterprise looks at UCaaS as the best communications solution, then it means that they are willing to place most of the control into the hands of the service provider.”

In a separate opinion piece, Daniel Teichman at Sonus Networks observes that real-time UC “such as Microsoft Skype for Business Enterprise Voice, has specific requirements for packet loss, latency, and jitter to ensure a quality experience. Successful service delivery requires knowledge of the network being used in order to meet those requirements, otherwise it is possible, even likely to run into user dissatisfaction.”

He continues with analysis that outlines three factors that should be well understood to provide a successful quality experience. He notes that to manage user experiences, a “commonly used option is for dedicated connectivity to be allocated between an enterprise and its Cloud provider, such as would be provided with a Multi-Protocol Label Switching (MPLS) WAN” and that “while this option is in use today and viable, it has several notable drawbacks in this new world of UC.”

Teichman concludes that, “a better option is to have bandwidth allocation and packet prioritization be done using a software-defined WAN (SD-WAN). In essence, the continuously-available data center architecture is now accompanied by a high-performance, highly reliable WAN to keep business up and running around the clock.”
