Silver Peak Sets Sights on New Enterprise Network: Unifies Cloud, Internet, and WAN on Single Fabric

Silver Peak today unveiled Unity, a groundbreaking intelligent wide area network (WAN) fabric that unifies the enterprise network with the public cloud. Unlike traditional WAN optimization solutions, 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 an ability it’s never had: 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 optimize 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 optimization,” 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 optimize connectivity to every SaaS application.”

Silver Peak software installed in data centers, 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.

“The rate at which our employees use cloud services has spread like wildfire,” said Jeff Wilson, IT director for Nevro Corporation. “With users in different parts of the world, I was not only finding it difficult to maintain consistent performance for my users, but I’ve been constantly surprised by new cloud applications popping up on users’ screens. Silver Peak has already been an instrumental partner in helping us accelerate data mobility for our VMware vCloud environment, and I’m excited to see Silver Peak Unity extend that expertise to give me the ability to control the performance and management of our core cloud-based services. Now we can punch a hole through to the systems that drive our business.”

Enabling the New Enterprise Network

Silver Peak Unity combines unique technology for monitoring, controlling and optimizing the new network:

  • Advanced WAN Routing: Advanced Exterior Routing identifies the closest egress to cloud data centers and directs traffic to a cloud service over an optimal path. Advanced Interior Routing dynamically selects the fastest, least-congested, or most available path for traffic by monitoring packet loss, latency, and bandwidth in real time.
  • Cloud Intelligence: This new subscription service delivers information about cloud services to Silver Peak software instances, creating an Internet weather map for intelligent routing decisions.
  • Accelerated Encryption: The Unity fabric is built on IPsec VPN security without any performance degradation, using AES-256 encryption with SHA-1 authentication and a simplified deployment model.
  • Data Reduction: WAN compression and deduplication inspects all traffic in real time, eliminating repetitive transmission of duplicate data.
  • Path Conditioning: Adaptive Forward Error Correction reconstitutes dropped packets in real time, while Packet Order Correction re-sequences packets that may traverse multiple paths across the network.
  • Traffic Shaping: Applications are classified to prioritize critical traffic classes while constraining recreational or personal-use traffic classes.
  • Global Visibility: Web-based GMS provides centralized orchestration of WAN deployments, advanced application classification, and detailed performance metrics.

Shining a Light on Shadow IT

The public cloud has become a powerful tool for increasing enterprise growth and efficiency. According to IDC, worldwide spending on public IT cloud services is expected to hit $107 billion in 20171. 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% of line-of-business workers and 83% 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 centralized gateways.” Gartner also projects that “through 2015, at least 50% of cloud deployments will suffer from network performance issues.”2

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.”3

According to a recent market analysis conducted by Doyle Research, the worldwide Intelligent WAN market is expected to reach $3.2 billion by 2018 and is growing at a rate of 20% year-over-year. “Public cloud adoption is placing significant stress on the WAN,” said Lee Doyle, principal analyst at Doyle Research. “This has opened the door for new WAN solutions that can maximize your return on cloud investments, rein-in Shadow IT, and enable highly reliable, secure networks with low-latency traffic to end users independent of their location or device type.”

Products, Pricing and Availability

Silver Peak customers can build a Unity fabric by upgrading to release 7 of Silver Peak software and subscribing to Silver Peak’s new Cloud Intelligence service. New customers simply purchase Silver Peak software and subscribe to Unity Cloud Intelligence. Customers can expand their Unity fabric by adding Silver Peak instances in cloud hubs or IaaS providers. The Silver Peak Unity Cloud Intelligence subscription is $5,000 per enterprise, per year and supports any SaaS applications. Silver Peak software instances are available for as little as $551 per year.

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
The Internet of Things will greatly expand the opportunities for data collection and new business models driven off of that data. In her session at @ThingsExpo, Esmeralda Swartz, CMO of MetraTech, discussed how for this to be effective you not only need to have infrastructure and operational models capable of utilizing this new phenomenon, but increasingly service providers will need to convince a skeptical public to participate. Get ready to show them the money!
