Networking blogs: Multivendor VPN tunnels still a hassle, but why?

This week's networking blogs investigates what's needed to streamline multivendor VPN tunnels and the impact the iPhone 5 will have on enterprise WLANs.

Setting up site-to-site VPNs between disparate vendors
Despite the Internet Protocol Security (IPSec) standard, bringing up a VPN tunnel between disparate vendors remains a challenge, writes blogger Jason Edelman. Wizards have helped, but even these have failed to ease the pain. And other tactics aimed at supporting the connection of  VPN tunnels from multiple vendors don't always go as planned. Maybe the real answers lie in the worlds of open source, programmability or software-defined networking?

Read what Edelman has to about possible ways to improve VPN tunneling.

Hybrid cloud pressures growing
Could the adoption of hybrid clouds among enterprises eclipse their use of public clouds? That's what Archimedius blogger Gregory Ness writes, citing recent announcements from Gartner and Microsoft. In fact, 2014 could be a tipping point for hybrid cloud momentum, and if that's the case, enterprises need to take careful steps to govern their hybrid cloud migration and integration. Smart managers will also keep a close eye on Microsoft's strategy to grow its Azure footprint, Ness says.

New iPhones mean change for WLAN
Got iPhone 5 in your enterprise? It's almost certain you do. Apple sold more than 9 million of its new model phones in just the first three days of their availability. Meantime, nearly 200 million iPhone and iPad users upgraded to iOS 7. All of this means your WLAN bandwidth is in for a jolt, writes Lisa Phifer. Some of what IT managers should expect is more video traffic, more 5 GHz and more streaming audio. And that's just for starters.

Proactive APM: What works
All enterprises and organizations want and need their applications to perform at optimum levels. But in the real world, glitches happen and when they do, application performance management platforms are a primary line of defense. But not all APM strategies are equal, says TRAC Research. Indeed, most organizations use their APM platforms for troubleshooting instead of proactive management. And from a cost-savings perspective, there's a big difference between reacting to an outage or a poor-performing application and being able to fix the problem before it occurs.
