Virtualization
Is it Linux? Is it third-party? Is it proprietary? Isn’t #vcmp just a #virtualization platform? Just what is inside an F5 BIG-IP that makes it go vroom? Over the years I’ve seen some pretty wild claims about what, exactly, is “inside” a BIG-IP that makes it go. I’ve read articles that claim it’s Linux, that it’s based on Linux, that it’s voodoo magic. I’ve heard competitors make up information about just about every F5 technology – TMOS, vCMP, iRules – that enables a BIG-IP to do what it does. There are two sources of...
#infosec #adcfw #cloud Alternate title: How to take out an entire PaaS cloud with one vulnerability Apache Killer. Post of Doom. What do these two vulnerabilities have in common? Right, they’re platform-based vulnerabilities. Meaning they are vulnerabilities peculiar to the web or application server platform upon which applications are deployed. Mitigations for such vulnerabilities generally point to changes in configuration of the platform – limit post size, header value sizes, turn off some value in the associated configuration. But they also have something else in common – risk. And not just risk...
The reaction in IT when there’s something wrong with a core router is to avoid disruption and its associated costs to the business. The reaction in IT when a user has problems is to embrace disruption and its associated costs to the business. ...
#VDI #quasar #mobile The proliferation of mobile devices is pushing VDI closer to being “the solution” of the year to resolve the increasing complexity – and costs – associated with consumerization. Considering the innate differences between just the two most popular mobile operating systems – Android and iOS – gives rise to understanding how costly and complex an infrastructure might need to be to support both. It’s not at all unlike the issues with server virtualization. Management and delivery architectures require different solutions depending on the platform, so despite potentially costly investments to scale, organizations are often staying...
It’s about operational efficiency and consistency, emulated in the cloud by an API to create the appearance of a converged platform In most cases, the use of the term “consolidation” implies the aggregation (and subsequently elimination) of like devices. Application delivery consolidation, for example, is used to describe a process of scaling up infrastructure that often occurs during upgrade cycles. Many little boxes are exchanged for a few larger ones as a means to simplify the architecture and reduce the overall costs (hard and soft) associated with delivering applications. Consolidation. But cloud has opened (or should...
#mobile #vdi #IPv6 In the case of technology – as with mythology - the whole is often greater (and more challenging) than the sum of its parts. The chimera is a mythological beast of scary proportions. Not only is it fairly large, but it’s also got three, independent heads – traditionally a lion, a goat, and a snake. Some variations on this theme exist, but the basic principle remains: it’s a three-headed, angry beast that should not be taken lightly should one encounter it in the hallway. Individually, one might have a strategy to...
#fasterapp If you know these three axioms, then you’ll know application delivery when you see it. Like most technology jargon, there are certain terms and phrases that end up mangled, conflated, and generally misapplied as they gain traction in the wider market. Cloud is merely the latest incarnation of this phenomenon, and there will be others in the future. Guaranteed. Of late the term “application delivery” has been creeping up into the vernacular. That could be because cloud has pushed it to the fore, necessarily. Cloud purports to eliminate the “concern” of...
#bigdata #infosec Storing sensitive data in the cloud is made more palatable by applying a little security before the data leaves the building… When corporate hardware, usually laptops, are stolen, one of the first questions asked by information security professionals is whether or not the data on the drive was encrypted. While encryption of data is certainly not a panacea, it’s a major deterrent to those who would engage in the practice of stealing data for dollars. Many organizations are aware of this and use encryption judiciously when data is at rest in the data center...
#adcfw The reason bars place bouncers at the door is because it’s easier and less riskier to prevent entry than to root out later No one ever said choosing a career in IT was going to be easy, but no one said it had to be so hard you’d be banging your head on the desk, either. One of the reasons IT practitioners end up with large, red welts on their foreheads is because data centers tend to become more, not less, complex and along with complexity comes operational risk. Security, performance, availability. These three inseparable issues often...
The shift of focus from north-south to east-west networking isn’t just inside the data center, it’s a global phenomenon It’s called “east-west” networking, which when compared to its predecessor, “north-south” networking, evinces images of maelstroms and hurricane winds and tsunamis for some reason. It could be the subtle correlation between the transformative shift this change in networking patterns has on the data center with that of El Niño’s transformative power upon the weather patterns across the globe. Traditionally, data center networks have focused on North-South network traffic. The assumption is that clients on...
