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…]

Optimize the management of network resources

Containing virtual sprawl by optimizing management of network resources.

As environments being more and more virtualized, the cost of computing goes down, efficiency, uptime and productivity increase and application performance is optimized. But, as with any major technology shift or revolution such as this, there are bumps in the road. That’s certainly true in the evolving data center. More flexible and scalable environments are being formed, to be sure, but there are a ton of challenges – adequately managing network resources for systems that were supposed to make our lives easier, for instance.

Why did this become a challenge? While the number of physical servers and related parts were being reduced, a potential new enemy was created: sprawl in the number of virtual machines – potentially hundreds of thousands of them. And with that sprawl, increased time and difficulty in provisioning virtual storage pools and virtual network resources. 

If you’re a network engineer or data center manager, you need to make sure business-critical processes are working properly – after all, you don’t have a lot of time to spend cataloging everything on the network. It’s not uncommon for me these days to have a conversation with overworked IT folks asking how they’re managing IP addresses – something that would normally be static and, in the past, could be done manually in a notebook or spreadsheet but which today simply doesn’t scale in this new virtual frontier. What’s needed are provisioning tools that can [Read more…]
