The benefits of virtualization are clear cut – massive financial savings in the long run. Virtualization enables organizations to use inexpensive hardware as terminals for multiple desktops which lowers costs in energy, hardware, maintenance and licensing. From a daily user’s standpoint, the convenience of accessing their personal desktops from any device effectively accelerates their time-to-value. However, the transition to virtualization can be costly and companies have to cough up now to achieve the benefits later.

Virtualization enables users to access distributed enterprise applications securely from any remote client device — when it works. If the network fails to perform against defined standards, end users of virtual applications and desktop sessions experience sluggish performance, system freezes and often outright disconnects. Regardless if Virtual Desktop Infrastructure (VDI)  is hosted in your own data center, or remotely, all performance issues – and finger pointing – will come down hard on an IT team.

While occasionally hosted on the LAN, VDI is more commonly reached over a WAN connection. If the performance of this link cannot be ensured, there is no point in virtualizing. Due to the nature of virtualization, a majority of stalls occur when employees are accessing their desktops over the WAN. Critical VDI links can become compromised during peak usage and need to be continuously monitored.

While we all know the frustration that slow applications produce, end users have zero patience for latency or poor performance when it comes to their entire desktop. VDI carries the highest sensitivity level of all applications and its success rating is directly dependent on user satisfaction.

IT professionals who do not pre-asses the network before virtualizing, put their jobs on the line. It is common to underestimate how much data is cycling weekly until there are attempts to move it, and taking an accurate reading of the WAN link is critical. Virtual software providers offer bandwidth requirements – but can the network guarantee that that bandwidth is available? Even during peak utilization? Is there space left to grow?

Requirements for a Successful VDI deployment

• Insight into the critical links while continuously monitoring the performance of VDI from the perspective of your remote site end users.

• Understanding of the measurement from the connection of end users back to the server and the ability to compare real-time against the key performance indicators needed by VDI services to perform properly.

• Alerting and reporting on network issues affecting system and virtualized application performance for pro-active troubleshooting.

Current tools used to monitor VDI include Xangati, Liquid Labs and Lakeside. These solutions are critical for monitoring the health and state of the virtual machines or locations where the application is being consumed. This means that the connection between end users and the virtualized servers is often left unsupervised. There may be green lights showing for all the devices, yet the phone is bright red with complaints. When polling devices produce a summary every few minutes, seconds of latency can be invisible on a monitoring screen, but it won’t be to the engineer who receives the phone call. VDI performance is dependent on the links between remote users and servers.

PathView Cloud offers the ability to assess, monitor and remotely troubleshoot performance from a virtual or physical system to any other target across LANs, WANs, even segments you don’t own or manage.

Organizations making the move to cloud services are well aware of the many benefits like lower startup costs, lower total cost of ownership and on-demand scalability. But many companies fail to take a hard enough look at the corresponding challenges associated with application availability and performance.

For many cloud services deployments, network performance will be the key to application performance. Why? Because every business service accessed over cloud infrastructure is by definition a remote, network-dependent service. Every user becomes a remote user and every office, even the corporate headquarters, becomes a remote office.

Even services-based applications will stumble, freeze and eventually disconnect users when network bandwidth, jitter, latency or packet loss metrics drop below acceptable thresholds. Many of the applications being moved to cloud infrastructure were not originally designed for remote access, making them even more susceptible to changes in network performance.

In short: a successful cloud services deployment depends on your ability to guarantee application performance from the user’s perspective. That means you need to manage network performance.

What are the key steps for managing network performance for cloud service deployments?

One: Network assessment

The first step in ensuring a successful cloud services deployment is to perform a comprehensive baseline assessment of network performance. When rolling out cloud services – or other IP-based services like VoIP, video conferencing, virtual desktop infrastructure (VDI) or IP storage – many organizations underestimate the operational and business risk associated with unplanned network impacts.

A network assessment is the only way to accurately know the scope of the project and its costs. It’s also the only way to know if your network is up to the task of carrying the extra traffic

Two: Continuous monitoring

Users need the performance of cloud-based services to be at least as good as what their current infrastructure delivers. To guarantee acceptable performance you need to be aware in real-time of the ever-changing status of the networks connecting remote users to applications. Latency, jitter and other key network performance metrics can fluctuate continuously in response to changes in traffic and other factors

Continuous monitoring capability is also required to give you real-time visibility into service levels. This is the basis for troubleshooting network problems, as well as for ensuring that cloud and other third-party providers are meeting their contractual commitments.

Further, the physical distance that data must take between the cloud and the user has a huge impact on performance, especially for TCP based applications. This parameter will vary among different public cloud providers, making monitoring performance over time an important step in evaluating cloud hosting options.

Three: Proactive troubleshooting

Today’s cloud-based services are business-critical and ensuring their availability is vital. Traditional break-fix approaches to network management are not adequate to meeting many of today’s SLAs.

Network engineers therefore need a way to pinpoint the exact cause and location of performance degradation — even within the virtual network and servers making up the cloud. This makes it possible proactively address network issues before they impact users. Likewise, if cloud services crash and a plethora of service providers start finger-pointing, you need to know, quickly and decisively, who is responsible for what.

Maximizing the business benefits of cloud deployments

How can organizations ensure that the performance of their network enables them to derive maximum benefits from cloud computing? AppNeta’s PathView Cloud technology enables you to guarantee application performance across all cloud, data center, remote office and mobile environments today. In addition to providing unmatched insight into network performance from the perspective of remote users, AppNeta’s cloud-based Pathview Cloud service delivers immediate time-to-value, affordable licensing and on-demand scalability.

Today’s business services are increasingly dependent on predictable network performance and availability. At the same time, changes to network infrastructure  – such as the addition of IP-based services like VoIP, video conferencing and Software-as-a-Service (SaaS); the proliferation of Wi-Fi-connected devices; unmanaged elements such as streaming audio– all mean that performance requirements for your customers’ critical applications demand a much higher level of service delivery and quality assurance.

Recurring-RevenueFor MSPs, your ability to provide continuous insight into customers’ dynamic network infrastructure is critical to delivering your existing services and ensuring a quick, effective response to customer performance problems. Some key elements to assuring performance for your customers’ networks and building your business at the same time include:

— Providing monthly reporting and immediate performance alerts when issues arise.

— Differentiating your business by moving from a traditional, break-fix engagement model based on remediating failures to a proactive, strategic service tailored to customer needs.

— Reducing trouble tickets;  eliminating truck rolls and on-site engineers

How can your business transition from break-fix troubleshooting to continuously and proactively managing your customers’ network infrastructure?

PathView Cloud offers remote site network and application performance monitoring that delivers exceptional network insight, alerts, reporting and troubleshooting, from one integrated network performance management solution.

Here are three easy ways MSPs can use PathView Cloud to get started with new remote, continuous network performance monitoring services:

#1: Network health assessments

Proactive network assessments are a great way to highlight network issues, while showing your customers the value of continuous network performance monitoring. PathView Cloud lets you deliver not only comprehensive, point-in-time assessment reports, but also continuous assessments over a business cycle (e.g., seven to fourteen days). This information can lead directly to a managed services discussion.

#2: “Top talker” reporting at remote sites

Who is doing what on your customer’s network? PathView Cloud enables you to give customers periodic (e.g., monthly) net flow reports that deliver valuable insight into who and what is consuming network bandwidth. Like a network assessment, this information can illuminate network issues while also presenting an ideal opportunity to discuss managed service options.

#3: Cloud services readiness assessment

Assessing a customer network’s readiness for cloud services is a simple undertaking with PathView Cloud. AppNeta recommends running such assessments for seven days to capture a full business cycle. A pre-deployment assessment can save your customers significant time and money by providing a holistic view of their network’s ability to handle additional traffic, as well as identifying ongoing and  transient network issues. It also facilitates a discussion of the value of continuous monitoring services post-deployment to validate and ensure compliance with SLAs.

More and more MSPs are using PathView Cloud to realize ongoing revenue streams from unmatched remote site performance visibility and continuous network assessment offerings.  Check out the live PathView Cloud demo, or try PathView Cloud on your network today with a free 14-day trial!


unified-communicationsThe cost reduction and infrastructure consolidation benefits of Unified Communications and Collaboration (UC&C) are so compelling that many organizations are rolling out these services without a solution to manage the user experience.

UC&C aims to converge telephony, messaging, mobile communications, video conferencing and presence-enabled applications onto a common, IP-based network. But chances are that network is already burdened with a host of services, from e-mail to SaaS applications to Internet media streams to online storage to virtual desktops.

The more traffic is loaded onto the network – and the greater the distance between the users and the services consumed – the higher the risk of poor network performance and application failure. UC&C applications, like many of today’s complex, network-dependent applications, falter and crash abruptly as soon as network performance degrades below a specific threshold. Even minor performance issues often result in degraded VoIP call quality, faltering videoconferences, or complete service failure.

Companies that hope to simply “drop in” UC&C services and expect they’ll work with no significant hiccups are taking a major business risk. To assure service delivery, UC&C systems demand stable and dependable network performance. This means not just sufficient bandwidth, but also minimal latency, packet loss and jitter.

Traditional, SNMP-based network management tools aren’t capable of monitoring the experience of remote users accessing IP-based services, which are entirely dependent on real-time network performance. Netflow analysis tools can help bridge the performance management gap, but they generally require significant bandwidth and are expensive to deploy and manage. Few organizations have the cash to deliver netflow analysis to and at the remote sites where the capability is most needed.

Network engineers and CTOs are well aware that in many cases their tools lack the “intelligence” needed to manage service levels across an ever-growing range of IP-based applications, including UC&C. Problem resolution becomes a time-consuming crapshoot, and capacity planning is simply a question of “how much bandwidth can we afford?”

To understand what’s happening with UC&C at remote sites, you need integrated network performance management capabilities that enable you to continuously monitor service levels end-to-end across any network infrastructure running IP-based services – even those hosted by third parties. You need to be able to:

  • Quickly and accurately assess a network’s readiness for a new or expanded UC&C deployment
  • Continuously monitor the performance of on-premise, hosted SIP or fully hosted UC&C services over any network
  • Cost-effectively measure and report on specific SLAs to meet and ensure the performance needs of your users

AppNeta’s cloud-based PathView Cloud network performance management solutions deliver instant value through actionable insight into the network performance metrics that are vital to the success of your UC&C deployments.

Today marks the launch of AppNeta.

Born of the best of the technology and team of Apparent Networks, AppNeta has a bold vision to bring the benefits of cloud-computing to the world of performance management. The transformation to AppNeta started in concept nearly two years ago, gained its first traction with the launch of PathView Cloud just over a year ago, and becomes official today with our first 1,000 customers under management and the official launch.
Apparent Networks has long been known for having compelling technology in the area of Network Performance Management, although compelling is probably an understatement.  Our core “Path” technology has been used by some of the worlds largest enterprise and IT Outsourcing accounts for years.  It has been judged by some of the most demanding customers in the world as the gold-standard for distributed network performance management (NPM).

Compelling?…YES.  Easy to deploy?  Affordable?  These were seldom the words that were used to describe the legacy solutions delivered by Apparent.  For customers who really needed our solution, there was no alternative.  Our patented Path technology remains the leading solution available in the market today.  But there were many (many!) customers who could see the value, but for whom the bar was set too high in terms of cost of acquisition and ownership.  All of that has changed with AppNeta.

Our mission at AppNeta is to deliver instant-value to network leaders by providing the insight they need to guarantee the reliable delivery of networked applications such as VoIP, Video, Cloud Services and Virtualization.

Instant-value?…YES.

A cloud-based service that is enabled by a zero administration microAppliance.  Just plug it in and gain unparalleled insight in support of your networked applications.  AppNeta’s solutions are simple to deploy and manage.  No software to download, no hardware to acquire, provision or manage.  Just plug in your microAppliance (included free with your annual SaaS contract) and get immediate network performance insight through the cloud, WAN or VPN.  Application performance insight from the perspective of your remote sites?  Absolutely.  All part of an affordable annual service contract.

Thanks to multiple snowballing trends like cloud computing, SaaS, virtual desktops, IP storage, mobility and Unified Communications and Collaboration (UC&C), more and more companies are delivering critical, network-dependent IT services to more and more remote users. The adoption of Cloud Computing has resulted in even the users at your corporate headquarters are now likely “remote” from core database or business systems. This recent change makes end-to-end insight into network traffic and performance absolutely business-critical.

As a result, many organizations now find themselves struggling to shift their network performance management focus from monitoring network device health to a prioritized, service-level orientation focused on the real-time, local experience of users consuming IP-based applications. That means you, the network engineer or CTO, must understand not just how the network is performing, but also what applications are running on the network and how individual users are consuming capacity.

How do you get this next level of insight to show you who is using what and where?  Netflow analysis tools have been available for many years from Cisco and other vendors. These tools get the job done but demand high-end network hardware and are costly to deploy and manage. First you need to over-provision the network infrastructure with high-end or redundant gear to handle the extra netflow traffic, and then you need to buy a netflow analysis solution and reconfigure the network to collect and analyze the data.

Historically, this has restricted flow analysis capabilities to headquarters and major data centers, rather than to and at remote sites. A few “free” or low-cost services have recently become available, but these are functionally restricted “teasers” meant to up-sell your organization to much more costly, traditional netflow solutions.

What is required today is a real-time summary of what applications are running on every network in your organization– and most importantly, how performance is affected.

Do you know how many streaming media sessions are running on a given network? Can you trace the cause of a traffic spike?

That kind of information needs to be universally available for every location, enterprise-wide, regardless of what hardware is in place. The information needs to be sufficiently granular to facilitate troubleshooting, enable auditing and reporting, and drive a service-oriented, proactive approach to network health. The solution needs to be easy to deploy and manage – no additional servers or gear. And it needs to be affordable, with a rapid time-to-value.

There is only one solution available that offers this level of “active” remote performance management capability: the FlowView add-on module to the PathView Cloud service from Apparent Networks. With FlowView, the PathView Cloud solution provides unsurpassed visibility into network performance, including the exact causes of surges in utilization based on the users on the network and the applications they are running. Enabled by the free, plug-and-play PathView microAppliance, FlowView requires no special hardware and uses a remarkably small chunk of bandwidth.

Already have a netflow analysis tool? FlowView is so cost-efficient, you can use it to feed a real-time stream of data into your current solution. This takes the load off your network gear to improve network efficiency and potentially forestall the need to purchase new equipment, while also leveraging your existing netflow investments.

Sound too good to be true? Visit www.apparentnetworks.com today to learn more.

Sound familiar? I know this is a question many of you ask yourself regularly, if not daily.

There aren’t too many people that would debate the value provided by understanding flow data: the ability to get deep and near real-time insight into the applications and users that are consuming resources on your network.  Flow analysis has been built into a wide array of network analysis tools so you have more options than ever before to understand your network usage. Additionally, flow tools no longer slow down the performance of routers and firewalls because high end and mid-range hardware is powerful enough to avoid the impact on these devices.

But, until now, getting Flow visibility to and from remote sites has been too expensive and cumbersome. Despite the evident value of understanding flow data, I see some major needs in getting this insight into remote offices in a way that is:

  • Easy – Admins don’t want to manage and maintain another server or software sensors at the remote site.
  • Inexpensive – it needs to be affordable enough to rollout to each office without breaking the bank.
  • Universally available – it needs to work at each office, regardless of which network gear is installed there.

There are solutions that may hit one or two of these, but until now all three have been elusive.  Today, Apparent Networks is officially integrating FlowView into the PathView Cloud service and brings all three benefits to network managers in a simple, cloud based package.

PathView Cloud has been built from the ground up to give you real time performance visibility to and from remote offices. With a cloud-based service enabled by zero-administration microAppliances, remote site organizations are finally able to get true end-to-end performance visibility. BUT, the first thing we hear out of peoples’ mouths is:

With PathView Cloud and the new FlowView module, organizations have an inexpensive option that not only gives them real time performance to and from all remote offices, it can drill down from those reports and view the users and applications in use at those remote offices.

FlowView is unique from most Flow Analysis systems in that it does not take flow feeds from existing network devices. Instead it creates its own flow records. A Gigabit Ethernet switch-tap is included free with the service which runs at line speed and sends a copy of all network traffic to the PathView Cloud microAppliance. We then analyze that traffic and generate Flow records that are securely sent to the cloud service for reporting, and can also be streamed to a local flow analysis tool for companies that have already invested in a tool.

FlowView was designed to be self sufficient, and does not require a span, tap port, or network devices capable of generating Flow records at the remote offices. At a total price of $499 (including one year of service, all hardware, training and customer support) FlowView is dramatically more cost effective than other flow-only solutions on the market and, quite simply, it can’t get any easier to use. Within the web user interface a single switch turns on flow analysis and the collection, streaming to the cloud through a secure, compressed SSL tunnel and in-line reporting with real time performance analytics is all done automatically.

Having issues with the performance from to or from remote offices? Well, you now have a tailor-made solution to finally answer “exactly what is going on at that remote office” in an easy, cost effective and universal package.
