If you’ve been around IT for even a few minutes, you’ve likely heard the acronyms “LAN” and “WAN” used by fellow technicians. But with all of the possible variations of networks—different sizes, different arrangements, and different protocols—how do you tell the difference between a LAN and a WAN and everything in between? The simple answer is one of scope and size.
Learn how Docker makes it easy to update, test and debug software with this white paper and gain foundational knowledge about Dockerfile, Docker images and containers.
Learn how Cisco FabricPath combines the benefits of Layer 2 Switching and Layer 3 Routing, allowing for the scalability and flexibility of Layer 2 while supporting traditional Layer 3 components such as optimal paths, equal cost multipath routing and a Time to Live (TTL) field.
The cloud revolution is truly a revolution - the way we work, learn and even play is very different now than it was just 10 or 15 years and will probably be a lot more different in 10 or 15 years. With this in mind, let's look at 10 ways the cloud will (and to a large degree already has) changed the world.
Cloud computing is a big force in IT today, and it isn't going away. In fact, cloud adoption is going up geometrically, both for end users (think apps on your phone or tablet) as well as for organizations of all sizes. In fact, many smaller organizations may not have any on-premises infrastructure at all, other than networking infrastructure to get connected to the cloud. With this transformation in IT, it behooves all of us in the industry to understand it and adapt or risk being out of a job, like punch card operators.
A range of factors can influence the data center you choose. You should consider all of the factors listed in this white paper before deciding where to place your servers.
This paper explains uplink strategies for traffic coming in and out of a Cisco Unified Computing Solution (UCS) chassis. An uplink can be Ethernet, Fibre Channel, or FCoE and is a physical connection on the FI that leaves the UCS domain directed away from the B Chassis.
Cisco Unified Computing Solution (UCS) is a very popular and powerful solution. Cisco continues to provide updated UCS management options for the full range of data center installations.
While there are differences between the IP Multicast configuration in the IOS and the Nexus OS, the Protocol Independent Multicast (PIM) protocol remains fundamentally the same. If you feel comfortable configuring Multicast in the IOS, you should be able to acclimate fairly easily to the changes in the Nexus OS.
Multicast Sparse Mode and its derivatives are supported in the Nexus OS. This white paper explains how it has been implemented in the Nexus platform to provide optimum performance in both virtual PortChannel and FabricPath environments.
The National Institute of Standards and Technology (NIST) created a cloud definition that has been well-accepted across the IT industry. NIST was mandated to assist government agencies to adopt cloud computing for their IT operations. As part of their mandate, NIST created multiple working groups to define cloud computing, its architecture, and requirements. In this paper we explore the center core of NIST's cloud definition.
The results are in, and analysis is complete from our seventh annual IT Skills and Salary Survey. This was our second in partnership with Windows IT Pro and one of the industry's largest with more than 12,000 North American respondents. Download your copy to learn how your salary, bonus, job function, and other factors compare to your peers.
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.
John Barnes, Global Knowledge's Cisco Course Developer, discusses enhancements to our UCS Troubleshooting Boot Camp and suggestions for students in preparation for this course.
Get a look at how your numbers compare to your peers and neighbors with our comprehensive lists below. A Note About Our Certification List For the condensed list of certifications in our 2013 IT Skills & Salary Report, we included only certifications that received enough responses to be statistically relevant. The list below is more inclusive. Certification data is for informational purposes only, as the values of some of the more exclusive certifications are based on few responses and, therefore, are less reliable.
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.
For the fourth year in a row, Global Knowledge and TechRepublic have partnered to create a comprehensive IT salary survey. With over 12,000 responses, the 2011 report has turned out to be one of this year's most relevant and revealing salary surveys in the industry. Below is our complete list of Salaries by Popular Certifications and Salaries by State.
The flexibility, reduced cost, and mobility of cloud computing have made the concept a hot topic. Before implementing this method of computing, however, it is important to consider the security of the "cloud." During this webinar, we will help you understand some of the risks and benefits of cloud computing so you can decide if it is the right solution for you.
The definition of cloud computing depends largely on whether you are a consumer or producer. The public cloud is geared more for the individual consumer or small company, while the private cloud is geared more for a medium-to-large company. In addition, the private cloud is branching out to incorporate the ability to have some data and applications serviced from the public cloud. This white paper examines the different types of cloud computing and shows what cloud computing can offer you.
The results are in from the 2nd Annual Global Knowledge and TechRepublic IT salary survey. With over 14,150 responses, our 2009 report is one of the industry's most relevant and revealing IT salary surveys. Our 2009 salary search revealed an average increase of 10% nationally over our 2008 salary study. Learn the top paying salaries for IT jobs based on state, industry, certification, and more.
