The amount of data being produced does not seem to show any sign of slowing; if anything, it may in fact be exceeding projected growth rates. As these absolute limitations on raw hardware capacity begin to be felt, the importance of looking at all of the aspects of a computing infrastructure in order to tackle the future's truly large-scale computing demands, is imperative. This white paper examines how IBM's initiatives like Linux, Cloud Manager with OpenStack and the OpenPower Foundation IBM are meeting this challenge.

PowerVM is the virtualization environment for AIX, Linux, and IBM i running on the IBM POWER hardware platform. This white paper provides an overview of PowerVM concepts, architecture, terminology, and capabilities.

The short answer (and a common one in our industry): it depends. When comparing Cisco IOS with Juniper Junos, the decision to choose one over the other is difficult and often boils down to cost. Of course, there are other factors to consider.

Regardless of your vendor preference or your experience on the Juniper JUNOS CLI, assuming you have a point of reference to another vendor, your first thought when experiencing JUNOS is, “I have been here before.” The CLI is familiar, convenient, and polished. The similarities between JUNOS CLI and another CLI such as Cisco’s IOS are not what I want to focus on here however; it is their differences I want to focus on. But first, when you connect to a JUNOS powered device and access Operational Mode (see Brad Wilson’s blog post Introduction to Juniper Junos), it looks very much like the User EXEC Mode in IOS. In fact, there are a lot of JUNOS commands that are very much like the IOS User EXEC Mode commands.

None of us have much time to waste, so what can you do when your environment changes quickly and you need to come up to speed on a device that you have never seen before? You find the quickest way to bring yourself up to speed. Some of you will have experience with other vendors’ equipment, and some of you will not have much experience at all; therefore, we will focus on topics that will get your feet wet the quickest and have you talking Junos in no time.
