Shining a light on shadow IT

Silver Peak has unveiled Unity, a new intelligent WAN fabric designed to unify the enterprise network with the public cloud.

Unity correlates information about cloud services and Internet “weather” to intelligently route traffic over a secure, optimal path. By keeping SaaS and IaaS traffic on the Unity fabric, IT gains the ability to monitor and control connectivity to the cloud while ensuring consistent SaaS performance.

“Most enterprises use dozens of SaaS services, whether IT knows about them or not,” said David Hughes, CEO of Silver Peak. “That usage will only increase as enterprises shift computing workloads to the cloud. The problem is, IT staff have no insight into that traffic once it leaves the WAN. They can’t troubleshoot problems or optimise applications the way they would on their own network. CIOs don’t want to be responsible for performance they can’t control.”

“Silver Peak Unity represents an entirely new approach to wide area networking, which steps beyond WAN optimisation,” Hughes continued. “We're giving the enterprise a complete map of the cloud-driven network and applying new routing and intelligence to help enterprise IT see, control and optimise connectivity to every SaaS application.”

Silver Peak software installed in data centres, branch offices and cloud interconnection hubs generates the Unity fabric, a network overlay that controls and accelerates connectivity to any combination of enterprise services, IaaS resources and SaaS applications. Each Silver Peak instance on the Unity fabric communicates with Silver Peak’s new Cloud Intelligence service, which aggregates constantly changing information about cloud providers and Internet weather. Unity uses this information, along with calculations from each software instance, to dynamically route traffic to the cloud over the optimal path. Orchestration is handled by Silver Peak’s Global Management System (GMS), which provides IT managers with complete visibility and control over the deployment and use of cloud services.

Shining a light on Shadow IT
According to IDC, worldwide spending on public IT cloud services is expected to hit $107 billion in 2017. However, as adoption of the public cloud grows, so too does the use of IT systems and solutions without organizational approval. According to a study conducted for McAfee by Stratecast, a unit of Frost & Sullivan, 81 percent of line-of-business workers and 83 percent of IT staff admit to using non-approved SaaS apps. This practice, often referred to as “Shadow IT,” opens a major gap in visibility, security and performance across the network and a headache for CIOs.

Gartner reports that “traditional enterprise WAN architectures are not well-suited for the adoption of cloud-based IaaS and SaaS solutions, due to increased latency and the cost of backhauling traffic to centralised gateways.” Gartner also projects that “through 2015, at least 50 percent of cloud deployments will suffer from network performance issues.”

Gartner analysts Andrew Lerner and Neil Rickard write: “Network architects should revise WAN architectures to improve performance for external cloud applications and resources. In most cases, hybrid WAN architectures will provide the best blend of performance and availability.”
