Doesn’t matter where you’re working

WAN optimization: the same network experience for all.

 As virtualization and cloud computing drive more and more traffic over wide area networks (WANs), end users are expecting and demanding connectivity to access their applications from anywhere and any device, any time. This in spite of the fact that poor application response times at remote sites are one of the biggest perceived hurdles to moving to the cloud in the first place.

 The challenge for IT then is to take on this performance and perception challenge by making the experience as seamless as possible for the end user, both in terms of application response and data transfer time. WAN optimization technologies are an effective way increase bandwidth and deliver application, data and experience consistently, scalably and cost-effectively so that users have the same network experience.

 Part of this challenge is not only to make the experience device-aware but bandwidth-aware too, so that you have the ability to change the way content is delivered based on the bandwidth that’s available. There are also a variety of techniques that can reduce, [Read more…]

Dealing with the complexity that virtualization brings

Bringing it together with Unified Network Management.

There have been a ton of changes recently in network security on the consolidation and virtualization front, changes that have brought with them a slew of benefits from admin and cost points of view but changes that have also increased complexity – and with it, decreased the ability for organizations to fully innovate and collaborate. And so one of the things to look for when it comes to security management is whether you can maintain consistency around the things you do while still eliminating some of the devices within your environment to achieve the innovation and collaboration you want.

Maybe, for instance, you can have virtual firewalls supporting multiple different domains but still running discreetly on the same physical box. Part of the challenge here, from a security standpoint, is to give you the capability to keep the bad stuff out and good stuff in but also to keep information from crisscrossing when it shouldn’t. Can you, if you will, create that firewall, maintain data integrity and separate, manage and secure very different domains even though they’re running on the same physical equipment? [Read more…]

The network balancing act.

Of virtual domains and load balancing: some benefits of network virtualization.

 It’s a common problem: by underutilizing their resources, most data centers end up deploying more servers than they need to. Those additional servers increase costs, of course, but they also create more disparate environments that are tough to manage. But now IT has the capability to buy single device items that, through virtualization, they can carve up into separate logical devices that look physically separated.

 That means you can create a virtual domain for a company or entity or line of business that’s run and managed separately, discreetly from other things in the environment even though each is sharing the same physical device.

 It also means increasing the value of your network devices and leveraging your infrastructure.

 Yet virtualization of data center infrastructure can bring with it an increase in security issues — around privacy, compliance, and business continuity, for example. So a lot of technology is being offered by vendors that can make sure, for instance, that devices coming on the network are trusted and that you don’t end up accidently putting something online or in a place where it shouldn’t be and create security issues.

 Another challenge when it comes to network virtualization centers around [Read more…]
