| How current WAN firewalls are flawed Last time, we mentioned that the current generation of WAN firewalls has not advanced as rapidly as the security threats that the firewalls are supposed to protect against. Today we'll examine that in greater detail and identify some of the key weaknesses in the current generation of firewalls. Next-generation WAN firewalls: First, a history lesson Some forms of WAN firewalls have been around for a couple of decades. It is hard to deny that firewalls are helpful. They are. It is also hard to argue that they are very exciting. In fact, since the turn of the century the types of security threats facing IT organizations has changed dramatically while the WAN firewall has not added much new functionality. That situation appears to be changing. As we’ll explain in the next couple of newsletters, a next-generation WAN firewall is being deployed that is intended to combat the security threats of the 21st century. The impact of VDI The last couple of newsletters looked at some of the challenges associated with implementing virtualized servers. This newsletter will examine some of the challenges associated with implementing a virtualized desktop infrastructure (VDI). The impact of server virtualization In the last newsletter, we began discussing some of the challenges associated with server virtualization. In this newsletter, we will continue that discussion by talking about some of the specific WAN challenges that are associated with server virtualization. The challenges of virtualization The recent IT Roadmap conference in Chicago began with Jim and two other analysts on stage being asked questions by John Gallant. Given the current economic conditions, the question and answer session focused on cost savings. One of the questions posed to Jim was, "Should IT organizations be looking to implement virtualization as a means of saving money?" Jim's answer was yes, but only if they realize the impact that virtualization has on the WAN, on management, and on application delivery. The next few newsletters will explain exactly what that impact is.
