Disruptive technologies:
Coming soon to an industry sector near you

Disruptive Technologies by Quest

Anyone familiar with Uber or Airbnb will agree that well-deployed disruptive technologies can be dramatic and industry-upending. Even so, if your business earns its living far from such events, you may think you have years yet before needing to deal with “anything like that.”

You might want to think again, however. This season’s analyst predictions about 2016* stand out for their warnings about the reach and speed of disruptive technologies.

Get ready for the zettabyte networking era

network management & performance

Many new technologies hold promise for your business —mobile devices, cloud computing, virtualization, big data, the Internet of Things — but they also pose challenges to your enterprise network’s performance and your ability to conduct effective network performance monitoring.

Often this is because many enterprise networks are based on outmoded models that result in performance bottlenecks as network traffic increases. Continue reading

3 Steps to Closing the BYOD Gap

BYOD Policy – BYOD Gap

In my last post, I discussed the gap between business units that enthusiastically embrace BYOD and IT departments, where BYOD is regarded with more hesitation.

Yet it’s clear: BYOD is not only here to stay, it is quickly becoming a dominant force that IT departments must deal with. And in most circumstances “just say no” isn’t an option; BYOD offers employees too many rich opportunities to boost productivity, innovation, and collaboration.

So what’s an IT department — your IT department — to do? Continue reading

5 Capabilities That Your Wireless Network Needs Now

wireless network management

We can’t afford to ignore the myriad of mobile devices and apps currently saturating our attention and wireless connections.

In my last post, I laid out some of the industry’s eye-popping numbers. This time, I’m offering up just one graphic (from Cisco’s recent Global Mobile Data Traffic Forecast Update) showing why you must upgrade your network infrastructure. Pronto. Continue reading

Your Wireless Network: Signs That the Tail has Begun to Wag the Dog

network management - wireless networks have become the primary network

In many companies, the wireless capability added on to their enterprise network a few years ago has become some employees’ primary network.

It’s a development that signals just how quickly mobile devices are proliferating the workplace. The so-called “consumerization of business” changes the way we work — and our data networks have to keep up.

This transformation has been in the works for a while. In 2011, market analyst firm Gartner predicted 80% of corporate wireless network technologies would be obsolete by 2015. Gartner may well be right, given the findings of more recent research. Continue reading

Virtualization, cloud services make a new network/app management world

laptops surrounding a world globe

In my last post, I pointed out that today’s speedy, low-cost connectivity is impacting network and application management. This time I’ll concentrate on the other significant trend changing network and application management: Virtualization and cloud services.

Today’s datacenter environments are not only quickly becoming hyper-connected, most have also undergone at least some degree of virtualization and use of cloud services. The combination results in new kinds of business applications and, ultimately, a new kind of network infrastructure that exhibits…

  • Greater traffic volume, notably storage traffic
  • A shift in traffic flows from top-down/bottom-up to peer-to-peer, server-to-server, and virtual machine-to-virtual machine (now as much as 80% by some estimates)
  • Increasing amounts of synchronization and replication data across the network
  • A flatter network hierarchy

Cloud Computing best practice: Always monitor your Cloud services

In order to know whether your Cloud provider is meeting the performance and availability parameters set out in your service-level agreement (SLA), you have to be able to monitor your Cloud services.

While you might not need or care to see detailed reports about the performance of your provider’s various infrastructure elements (VMs, storage, etc.), since this information doesn’t really provide a sufficient view into overall Cloud performance, you can and should seek information from your provider regarding application and/or workload performance.

Automating network performance: 6 key capabilities

Capabilities to look out for in a Network Performance Monitoring Provider

The right network management capabilities will provide the feedback you need to eliminate bottlenecks and IT failures while also enabling your network’s ability to deliver data, voice, wireless, Internet, and video services.

Which is why adequate performance management, trending and capacity planning, protocol analysis/fault isolation, and onsite/remote network health monitoring have become so essential.

Is server virtualization messing up your network’s performance?

Impact of Server Virtualization on Network Performance

Thanks to virtualization, network dynamics are changing — fast.

Server virtualization consolidates resources on fewer physical servers in ways that require distributed workloads to communicate with each other. This boosts utilization of servers, but it also increases — and changes the nature of — network traffic.

Isolating and resolving network problems

How to resolve Network Problems.

When it comes to keeping your IT network performing optimally, finding and fixing network faults certainly is crucial. But it’s just as crucial to sustain network operations while the issue gets resolved.

Which means that the first order of business is to ensure that your network has entered one of the failure modes you’ve designed for it so that remaining network resources are allocated according to your organization’s business priorities.
