VeloCloud Enhances its SD-WAN Service with Zscaler and Websense

VeloCloud Networks, a start-up offering a subscription-based, virtualized WAN service for enterprises that aggregates multiple access lines (cable modem, DSL, LTE) into a single secure connection, announced interoperability with leading cloud security platforms Zscaler and Websense, spurring growth of its SD-WAN ecosystem. VeloCloud has also expanded its business policy framework, enabling enterprises, for the first time, to deploy cloud network services and applications easily and with assured enterprise-grade performance.

VeloCloud's SD-WAN service uses an Intel-based customer premise device at a branch office to communicate with a VeloCloud gateway in the cloud. The service analyzes network performance and application traffic to determine the best path and dynamically steer traffic to corporate data center or cloud services.

The new capabilities from Zscaler and Websense bring new virtual services to the platfrom. VeloCloud enables enterprise branch offices to achieve the same security services as corporate headquarters—without having to install multiple, separate appliances in each branch or backhaul traffic over expensive private links to their data centers. VeloCloud’s extensible business policy framework for network services insertion will cover additional services from its growing ecosystem.

In addition, the business policy framework adds explicit link usage policies for business and security compliance, augmenting VeloCloud’s existing automatic multi-path optimization which dynamically steers traffic to achieve enterprise-grade application performance. This business policy framework is transport independent, and also applies to private lines such as T1/MPLS as they are integrated into VeloCloud’s management and optimization of hybrid WANs. The expanded business policy framework provides software-defined WAN flexibility, simplicity and automation over both network services and transport utilization.

“VeloCloud’s Cloud-Delivered SD-WAN brings software-defined flexibility and automation to the WAN, and the policy-driven insertion of network services announced today extends our no-compromise SD-WAN simplicity, application performance and security,” said Sanjay Uppal, CEO and co-founder of VeloCloud. “Our comprehensive business policy framework replaces today’s complicated configuration and stacks of appliances in branch sites with single-click direct access to both on-premises and cloud-hosted services, including those from Websense and Zscaler.”

“For distributed enterprises, equipping branch and remote offices with secure, high-performance access to cloud services has been complex and expensive,” said Punit Minocha, vice president of business development for Zscaler. “Now that our partner VeloCloud’s SD-WAN solution is seamlessly integrated with Zscaler’s cloud-based Internet security platform, distributed organizations can securely and safely leverage the power of cloud computing, while dramatically reducing costs, increasing performance, and improving employee productivity and satisfaction.”

Blueprint: What’s Wrong with the WAN?

by Khalid Raza, CTO, Viptela

Today’s WANs are built on largely the same infrastructure as they were 10 years ago.  Back then, demands by users and applications were more predictable, resulting in more expected traffic patterns and bandwidth requirements.  And there was no cloud.  And there was no virtualization.

But things are different today.  Delay-sensitive real-time applications such as VoIP and video are now enterprise staples. Network traffic patterns are shifting due to the cloud, data center consolidation, and remote and mobile workers. Added to this are the performance burdens introduced by desktop, server, and application virtualization. The result? Network professionals are having major challenges with traditional, rigid WAN architectures that cannot meet the demands of today's traffic and applications.

What’s more, the cloud has upset the status quo in which the data center is at the hub of the network.  Today's public, private, and hybrid cloud environments are expanding the boundaries of the enterprise network. As a result, ensuring connectivity and security across an enterprise is an extremely arduous task, and rolling out a new service for WAN users in this much more complex environment can take months.

The enterprise architect’s list of priorities is long, including:

  • Delivering and managing connectivity across such disparate transport networks as MPLS, Broadband, LTE, and Metro Ethernet
  • Embedding policy and control at every hop in the network 
  • Mitigating network security vulnerabilities created by inadequate network-wide segmentation and weak encryption policies 
  • Dealing with long lead times to provisioning new applications 
  • Managing perennial performance issues related to public cloud, VDI, and bandwidth-hungry applications
WAN the New Way

Solving the aforementioned WAN challenges without added distributed complexity requires a comprehensive yet simpler approach. This is where Software-Defined WANs (SD-WANs) becomes an effective approach for the network architect. Essentially SD-WANs solve challenges related to scalability, performance, and rigidity.  And best of all the cost arbitrage between MPLS and broadband make this a compelling approach, with 50% savings right from the start. The essential building blocks of an SD-WAN are:
  • An encrypted overlay of MPLS and broadband 
  • Integrated routing and application-aware traffic steering
  • End-to-end network segmentation 
  • Centralized management of policy and control 
  • Optimization of Layer4 – Layer7 network services and cloud applications 
The end result is an enterprise network that is agile and easy to control, and that provides secure segmentation of traffic from different lines of business and business partners. A network built in this fashion enables CIOs to significantly reduce costs, dramatically improve time required to enable new services, and raise the security threshold across the network.

Apart from improved capacity on the network, some use-cases for SD-WANs include:
  • Guest Wi-Fi.  In industries such as hospitality and healthcare, where guests are granted access to the corporate network, IT needs the flexibility to establish a secure network segment that provides specific services to guests while keeping them isolated.
  • Cloud performance. In addition to increased capacity, cloud performance is determined by efficient routes to the service provider. SD-WANs enable aggregated exit points to the Internet with local peering in colo facilities, bringing down latencies by more than 50% typically. 
  • Business partners. Business partners may require access to portions of the enterprise networks, but are isolated from all sensitive content. Network-wide segmentation with centralized policies can prevent those risks.
Given today’s more complex networks, combined with the diversity of new devices accessing data on corporate networks, legacy WAN architectures are quickly becoming antiquated. Clearly, the range of benefits from a secure, high-performance WAN is immense across a wide range of applications.

Riverbed Boosts its WAN Optimization for Hybrid Enterprise Clouds


Riverbed rolled out significant enhancements to its flagship products – Riverbed SteelHead 9.0 and Riverbed SteelCentral AppResponse 9.5 – with a focus on visibility, control, and optimization to accelerate performance of on-premises, cloud, and SaaS applications. The company sees enterprises moving rapidly to hybrid cloud architectures, where business traffic flows over both predictable WAN trunks and myriad Internet links between mobile users and their favorite cloud services. The new challenge is not only to handle congestion, but to ensure security, control and visibility of these new "Shadow IT" resources.

“Riverbed is now poised to do for cloud and SaaS applications what we’ve done for more than 1100 applications across the wide area network for the last decade,” said Jerry M. Kennelly, Riverbed Chairman and CEO, speaking at its Riverbed FORCE 2014 conference in San Jose, California.  

Riverbed customers have now deployed over 750,000 SteelHead appliances, giving the company a deeply embedded platform upon which to build further innovations in network management.

To accelerate the transition to global, hybrid enterprise networks, the company is also kicking off a Riverbed-Ready Technology Alliance program with 17 charter program members. Partners can leverage Riverbed open APIs and additional development tools to help with customization, integration, and automation.

Some highlights of the coming enhancements to the Riverbed platforms:

SteelHead 9.0 integrates with SteelCentral AppReponse 9.5 to provide visibility of on-premises, cloud, and SaaS apps.

  • SteelCentral AppResponse 9.5 can measure end-user experience for both SteelHead-optimized and non-optimized enterprise web and SaaS applications for faster, more effective monitoring, and troubleshooting
    .
  • SteelHead 9.0 can group applications according to their type and business priority to automate SLA activation for different types of apps.
     
  • SteelHead 9.0 brings centralized, application-driven control of hybrid networks with “business intent”-based policies that make it easy to configure and manage path selection, quality of service (QoS), and secure transport.
     
  • With Path Selection, SteelHead 9.0 intelligently derives all network paths and, based on business needs then prioritizes, secures and delivers business-critical applications over the fastest networks, while less critical applications are sent over the Internet. For example, Microsoft Lync voice traffic can be delivered over MPLS, while Lync video traffic is directed to the Internet.
  • SteelHead 9.0 identifies over 1,100 applications – on-premises, cloud, and SaaS – which can be optimized for maximum productivity. Riverbed is rapidly expanding the number and type of applications that SteelHead recognizes, with a particular focus on SaaS apps.

  • Geo IQ for Microsoft Office 365 – The latest release of SteelHead 9.0 also offers Geo IQ for Microsoft Office 365, which ensures users are always connected to the native mailbox for optimal performance no matter where the Office 365 mailbox or the user is located.
