Simplify your Business Networks with Citrix SD-WAN!

You may have heard by now of the new technology that’s been getting a lot of buzz over the past years, software-defined WAN or SD-WAN.  This exciting technology enables organizations to reduce network complexity and cost while improving flexibility, security, availability, and visibility.  Citrix has made use of this technology and improved on the concept into what is now known as Citrix SD-WAN.

Citrix SD-WAN builds reliable WAN from different network links such as MPLS, broadband, 4G LTE, Satellite, etc.  It also is able to constantly monitor the condition of every link with its unique per-packet selection algorithm which also makes use of instant path selection decisions as each packet comes into the SD-WAN for transmission.  In turn, results in having the best path chosen at each given moment.  When users or the applications they use request for more bandwidth, Citrix SD-WAN can distribute the traffic using all available links which creates a secure virtual path through the aggregation of all of the individual links, so no link stays passive.

When your network has issues with bandwidth usage, the improvement of performance that users will see is not only felt through more bandwidth, but through the enablement of QoS control over link types that don’t usually provide QoS such as the internet.

Some key features in which Citrix SD-WAN can simplify your business network:

Centralized management and configuration of all devices. leveraging the use of templates for WAN, QoS and Firewall configurations. No more logging into each branch router to add a QoS rule or access-list for a new application – you just add to a global template and it’s automatically updated on all branches.

Zero Touch Deployment (ZTD). It makes a huge difference in large scale deployments. The branch appliances can automatically connect to the Citrix ZTD service in the cloud and download the required configuration, licenses, and software updates. No need to login to the appliance, just plug the cables. All controlled from the central management and secured by built-in authentication.

Improved visibility. Since all traffic passes through SD-WAN, it can give you a much deeper understanding of what is going on in the network, up to the application-level with its built-in DPI (Deep Packet Inspection) capabilities. Not only will you get visibility into the most used applications, it can also provide application-level QoE (Quality of Experience) measurements.

VeloCloud Kept Users Connected during the Level 3 Outage!

Internet connectivity is now easily one of the most critical components in a business now.  Without it, many aspects of companies would not function and result in many lost opportunities and big loss to profit.  One such example would be what happened on November 6, in which Level 3 an ISP backbone used by many internet providers in the US went offline for 90 minutes.  This was a disaster to many as they panicked due to the huge impact it had to their business and livelihood.  However, this was not the case for SD-WAN users. In fact, many VeloCloud users were not even aware of an internet blackout until the next day.  This is thanks to VeloCloud’s Dynamic Multipath Optimization.

With Dynamic Multipath Optimization (DMPO), all transport links are monitored on a continuous basis and when issues arise, traffic is steered proactively, dynamically and automatically on a sub-second basis to an alternative transport path(s).  This dynamic steering was what prevented VeloCloud users from experiencing the 90-minute blackout other Level 3 subscribers felt.  VeloCloud’s sub-second steering allows independent decisions in both uplink and downlink directions without introducing any asymmetric routing to avoid impacts from brownout or blackout conditions.

Below are some examples of the impact of the Level 3 outage on VeloCloud Cloud-Delivered SD-WAN:

First example is of a customer with dual Comcast links and a single Verizon LTE link in active mode.  From the Quality of Experience screenshot, you can clearly see the packet loss and jitter indicated by the yellow and red bands.  The long stretch of red from the Comcast links was the portion of the day when Level 3’s outage happens, the red band of course meaning there was almost no passable way for traffic to go through that link.  From the overall VeloCloud enhancement, you can see that the customer experienced almost no downtime of their connections even though the Comcast links were in the red for so long.

The second example will be a VeloCloud user who uses a broadband cable internet link and a DSL link.  The Comcast cable link again is using Level 3 as its ISP backbone.  From here, we can see an even better result as the customer had no downtime whatsoever as there was no red band after the VeloCloud enhancement even when the Comcast link had almost no connectivity it was still able to get a quality score of ever 9.94.

Power Shift in the SD-WAN Market

The SD-WAN market is seeing more and more businesses opting to integrate SD-WAN solutions into their IT systems. One of the rising stars of the growing industry, Velocloud, has gone with the approach of making SD-WAN “as a service”.  In an interview with CRN, VeloCloud CEO Sanjay Uppal explained his insights on the SD-WAN market, more specifically SD-WAN as a Service model.

“As things shift into more white-box and commodity hardware with software running as a service on top, the power is shifting,” said Uppal. “The move is afoot in terms of the power shifting to the buyer and they want SD-WAN as a Service, not SD-WAN as just another box. … No longer are people going to be locked in to custom hardware and proprietary platforms.”

VeloCloud, being under the model of “as a Service”, is precisely what sets it apart from the competition as no one else in the industry is following this solution model.  Majority of the competition either sell it as product, software or event more recently as a cloud gateway.  VeloCloud however, sell it to the customers on a consumption basis, what they need is what they get.

At the end of the day, if you go to an enterprise whether it be retail, banks or insurance, their main concern will be the business result or ROIs (return on investment).  In which VeloCloud sells them solutions which are tailor made for their problems, not based on what is the highest performing model.

VeloCloud puts its efforts on the outcome that the CIO is going after and then all of the architecture and programs that they put in place for the channel really support that.  This allows VeloCloud to go to the MSP and service provider and say, ‘We have a running system with over 700 enterprise customers. … We can train you on how to run this service, how to create demand for this service, how to train your people for it, how to do the logistics and support.’ That’s what the channel wants to hear.

VeloCloud Launches a SD- WAN Security Technology Partner Ecosystem!

The SD-WAN market is growing at a very fast pace.  It is estimated to exceed $6 billion in revenue worldwide by 2020 while still compounding an annual growth rate of more than 90% over a forecast period between 2015 to 2020.  By 2018, it is also expected that about 82% of North American enterprises will be using SD-WAN which is remarkable considering the technology is still in its early days.

With the option to choose what kind of link is best in a given situation (MPLS, broadband, LTE, or any combination of these), besides optimizing your WAN link, you will also be able to provide additional capacity to avoid blackouts and brownouts.

With such features, VeloCloud makes sure to take the necessary steps to ensure that your data will be secure when using its comprehensive SD-WAN solution.  Recently, VeloCloud has taken a big step towards a more comprehensive security ecosystem which it calls the “SD- WAN Security Technology Partner Program”.  A multifaceted effort of collaboration between a wide range of technology companies to help protect users’ branch, data center and cloud networks which results in a top notch end-to-end security option for SD-WAN which seamlessly includes both on premise and cloud networks.

Partners are given access to VeloCloud’s APIs through a formal software development kit which helps simplify the process for partners who are interested in developing security solutions for VeloCloud’s SD-WAN architecture.  VeloCloud has also opened up a virtual network function (VNF) framework to its partners in the security ecosystem to help develop their own security VNFs within its framework.  VeloCloud also allows for cloud security by allowing third party security vendors to bring their own services into marketplaces operated by service providers such as Azure and Amazon.

Besides the security ecosystem, VeloCloud also has its own security capabilities which are integral parts of its SD-WAN architecture.  One example would be its zero-touch deployment model in which you can be shipped a non-configured VeloCloud edge to any of your branches or remote locations and once connected to your link it will securely authenticate and encrypt across your network.  With its unique way of key management for vCPEs on your network, it will be able to help check your tunnel integrity while helping with scalability and your dynamic multipath VPN.

CT Link Systems Partners with VeloCloud for SD-WAN

It is a common consensus that the Philippines has one of the lowest average internet connection speeds in the world. According to Akamai’s Q3-2016 State of the Internet report, the Philippines ranks 103 globally with an internet connection speed averaging only 4.2 mbps.  Majority of internet connections in the Philippines are below this average.  Only 29% of the connections are above 4 mbps; a low 5.4% of connections are above 10 mbps; a dismal 2.4% of the connections are above 15 mbps.  Moreover, not only does the Philippines have a low average internet connection speed, it also ranks one of the highest in terms of internet service costs compared to other countries.

The Philippines’ internet infrastructure is preventing many enterprises from adopting cloud services such as Microsoft Office 365 or Azure. We also hear from customers about their challenges in availing reliable and cost-effective wide-area-network infrastructure services to interconnect their nationwide branch network.

To help customers establish a more reliable WAN infrastructure at a more reasonable cost, CT Link is partnering with VeloCloud to offer SD-WAN services in the Philippines.

VeloCloud, a Cloud-Delivered SD-WAN pioneer, simplifies branch WAN networking by automating deployment and improving performance over private, broadband Internet and LTE links for today’s increasingly distributed enterprises, as well as service providers.
