In reviewing the list of best-paying jobs in IT, you’ll see some areas you might expect like cloud computing and other areas you probably didn’t, like business technology or enterprise infrastructure management. The top 10 functional areas are based on the 2016 IT Skills and Salary Survey conducted by Global Knowledge in October 2015. Note that all references to “average” represent the mean, not the median or other statistical measures.

In this article, we discuss how to achieve that optimal security approach in the data center with Cisco Application Centric Architecture, or ACI.

This webinar will look at Border Gateway Protocol and explore why we have the protocol; how its involved and how it works. We will look at how and where BGP is used in today’s networks and Internet. We will look at the basics of configuring it and some not so basic configurations.  

As I’ve stated before, I like Border Gateway Protocol (BGP). I think it’s an interesting protocol, and yes — it’s complicated, but I guess that part of why I like it. There are a lot of knobs to tweak in BGP, maybe too many, but that’s another post. Anyway, we are now running BGP version 4 and it has had extensions written that support more than just IPv4 unicast routing. We now have IPv4 multicast, IPv6 unicast and multicast, VPNv4, VPNv6, and a few others.

Every data center has unique hardware and software requirements that can pose significant management challenges to IT.

Business and IT alignment is not a one-and-done thing. On the contrary, business strategies and goals continually evolve and cascade down to more specific needs throughout the enterprise — including IT. To stay aligned with the business, the IT side of the house should consistently ensure that it and the business both understand what outcomes are desired in strategic, tactical, and operational contexts. At the same time, IT should build up the disciplines required to enable — and ultimately track — those outcomes.

Agile is a set of principles requiring a significant cultural shift, new paradigms in thinking and team organization. Over the years, Agile has become "productized" or in many cases "institutionalized", creating different flavours and levels of commitment among teams and organizations. Along the way, managers and team members have lost sight of Agile's principles and tried to enforce the use of certain tools and structure where they may not belong. In this one hour webinar, Perry McLeod will explain how tools such as use cases can be successful in an agile environment, provided the principles of agile are always active in the minds of the managers and the team members that are using them. Join Perry to determine whether or not making the cultural shift towards the use case method in an agile environment is the right move for you and your organization.

I am a VMware Certified Instructor and every single time I teach, I get questions regarding certification. IT certifications always seem to be a controversial topic, and the question is always, "Why should I become certified?"

Early one morning, an engineer end user discovered that the Engineer servers were unreachable, and he didn’t know if he could reach the Internet. The administrator investigated the user’s PC with the IPCONFIG /ALL command and verified that the PC was a DHCP client, but it had received an address from the Accounting DHCP server, not the Engineering DHCP server.

This week we'll review the IPv4 Address Classes including subnet masks, examples of Class C, Class B, and Class A subnet masks, and planning IPv4 addresses.

Anyone who’s managed switches over the years knows that the Spanning-tree protocol (STP) is both the best and worst thing to ever happen to the data center at layer 2 of the OSI model. On the plus side, the Spanning-tree protocol is what first allowed us to create redundant paths within our switching infrastructure, making our data center much more resilient to outages than ever before. Anyone who’s experienced a “broadcast storm” knows the full value of Spanning-tree in the traditional switching environment. We’ve also seen many improvements in Spanning-tree over the years to make it work faster and more efficiently (i.e. Rapid Spanning-tree, Bridge Assurance, and many others).
