How do you measure the experience and knowledge of an IT professional? One way is through certifications. Earning any certification is a notable achievement, though not all certifications carry the same perceived worth.

IT is a very fast changing industry – what is hot today may be a tiny niche market in only a few years and lesser known things may turn out to be huge trends. That having been said, there are many certifications that will be around for a long time. However, this does not imply that recertification and/or continuing education credits are not required to maintain certification. Predicting the future is always challenging, including in IT, but these certifications are good bets.

Digital transformation means different things to different people. One fact they all agree on is that the capability needed to manage this new paradigm will lead to new ways of working, new skills, new technology and embracing more collaborative ways of co-creating value. That challenge has been the driving force for the latest iteration of ITIL®.

ITIL® 4 reflects new ways of working that have accompanied the digital revolution. Service Management, and ITIL in particular, is still an important toolset but you are now integrating its adoption and use with a vast array of new ways of working (DevOps, Agile, SIAM, Site Reliability Engineering). Since ITIL v3 was released in 2006, a large number of new and updated technologies (Cloud, Serverless Computing, Software-Defined Networking, AI, etc.) have emerged that now need managing. ITIL 4 reflects these changes. Here are some frequently asked questions about ITIL 4, as well as answers that explain what it entails, why we need it and how it differs from ITIL v3.

ITIL Foundation Exam-Taking Tips

A lot of IT pros would like to get their work to fund their training and certifications, but if the issue isn't approached with care and forethought, it can be dangerous territory. So how do you justify the costs of training? Luckily, a help desk tech in the healthcare field named R. Lee Young offered up some great suggestions.

Thinking about getting ITIL certified? In this post, we cover the value of each ITIL certification and dive into survey results to determine whether ITIL certifications are worth it. The results are in!

Certifications are the most common way in IT to prove you have the skills to solve various technical and business challenges. In this article, I'll address a range of skill sets. For each certification listed, I've included what the certification measures, the requirements to obtain it.

You may have heard about IT service management and ITIL being yesterday’s news, but the survey suggests you need to re-evaluate those rumors. The enduring value of ITSM credentials and practices have been championed by Gene Kim, one of the Godfathers of the DevOps world, who has said, “It is my firm belief that ITSM and the DevOps movement are not at odds. Quite to the contrary, they’re a perfect cultural match.”

Shortly after being awarded an ITIL® Foundation certification, a recipient’s natural inclination is to ask: “Now what? How do I take the best practices I’ve learned and apply them to my organization?”

As the technology industry has advanced, the professional certification industry has grown alongside it. The Global Knowledge 2016 IT Skills and Salary Report revealed that Cisco, Microsoft, IT service management, ITIL and security certifications are the most lucrative to obtain.

The methods we have used in the past to secure our networks won’t work for tomorrow’s networks. Cloud-based applications and multi-tenant environments require greater scalability, agility and control. Software-defined networking (SDN), such as that provided by VMware NSX, can deliver a new platform that transforms networking and provides for much more specific control of the security of your data and networked applications.  In this white paper, author Bill Ferguson describes the microsegmentation of security and illustrates how you can use NSX to provide security that works on today’s and tomorrow’s networks.

The VMware NSX platform combines networking and security functionality directly in the hypervisor and it interoperable with a vast majority of VMware’s products. The platform provides a set of logical networking elements and services, using logical switching, routing, load balancing, VPN, firewall, etc. This product decouples network functionality from the physical devices.

VMware announced Horizon 7 in February and subsequently released the software updates. Horizon 7 provides a more streamlined, high-performance virtual desktop and application experience. New updates include features such as Instant Clones, Smart Policies, Blast Extreme and greater scalability with Cloud Pod Architecture. Let’s dig into the seven key features that Horizon 7 brings!

IBM WebSphere Business Modeler (WBM) can be used in conjunction with an adoption of ITIL best practices. It is a full-featured process modeling and simulation tool that fits well with other IBM products that are used to define various service management processes and activities. In this white paper learn more about how WBM provides both the ability to visually define process activities and the ability to define detailed information about processes, including inputs, outputs, cost, revenue, roles and resources.

Which mainstay certifications should be in your list of credentials? What's the next up-and-coming certification? This article will help you answer both questions by providing a review of the 15 top-paying certifications.

AMC’s television series “Halt and Catch Fire” shows North Texas’ rise as the “Silicon Prairie.” In the 1980s and early 1990s, it’s where IBM PC cloning was explored and where first-person shooter games were created. It’s also the site of the first “logic bomb”—the source of my horror story.

Using ITIL can improve your IT service levels, customer service ratings, business productivity and reduce operating costs, but getting started can be overwhelming. Gain the understanding you need to adopt and adapt ITIL with instructions and tips for important steps such as internal employee communications, determining potential pain points and methods for evaluating your existing processes.

Businesses today are more dependent on technology than ever. And, more than ever, they're looking to IT for ways to improve employee productivity, customer service and innovation. The challenge is that in order to achieve results with technology, IT and the business have to work collaboratively. IT needs to be able to develop the right relationships and communicate with different stakeholders from a business perspective - not a technical one. As a result, the transformation of the IT department has become a top-level priority for many leading organizations. At the same time, business leaders need to strengthen their business technology IQ and play a more significant role in the governance of IT.

The ITIL® event management process defines three event types: informational, warning and exception. In this post, I will discuss the different event types and give real-world examples of each.

Change is the order of the day, and if anything, the pace of business and technology change is accelerating. The business and customers are looking to IT service providers to be more responsive, delivering more frequent service changes with higher quality-resulting in services that deliver more value to the business. In order to continue to be relevant and of high value, ITIL must continue to benefit from other complementary best-practices for IT. DevOps, an approach that encourages improved communication, collaboration, and teamwork across development and operations, can have a positive influence in improving ITIL processes across the service life-cycle.

This white paper describes a technique for defining processes called SIPOC (Suppliers, Inputs, Process, Outputs, and Customers). SIPOC provides a structured way to define the key elements of any process. SIPOC can be used as a means of defining any of the service management processes presented in ITIL® best practices. Furthermore, SIPOC can be used as the preliminary input into the more formal documentation of a process in one of many process design tools.

It’s not uncommon for different teams to be managing the virtual switch and physical switch configurations. This can make it very difficult to troubleshoot unless each configuration parameter has been gone through manually. There have been enhancements to the vSphere Distributed Switch over the past few years to address these operational challenges.

In this hour-long webinar, Global Knowledge instructor and ITIL Expert Michael Scarborough will share his knowledge and expertise on various aspects of incident management and problem management processes. He will help you understand the difference between incidents and problems and between incident and problem management, providing examples from his own experience to drive the concepts home. Michael will also provide an overview of who performs various incident and problem management activities in an organization.

Virtual storage area network (VSAN) and VMware View can offer cost savings and performance benefits compared to traditional SAN implementations for virtual desktop infrastructure (VDI). If you are starting a new desktop virtualization project, it would be wise for you to take the time to explore your options and compare VSAN to other options.

There are two types of virtual switches available using vSphere, the vSphere Standard Switch and the vSphere Distributed Switch. The vSphere Standard Switch (vSwitch or vSS) resides in and is manually configured and administered on each ESXi host. The vSphere Distributed Switch (dvSwitch or vDS) provides similar functionality but is centralized to vCenter Server and is more featured. This white paper will cover the vDS architecture as well as an overview of many of the different features that are exclusive to the vSphere Distributed Switch.

He will provide a high-level guide for establishing a change management process that uses real-world examples as its basis.

One of the advantages of vSphere is that you can move a virtual machine from one location to another, across servers, storage locations-even data centers. Physical servers don't have that ability and that can have many implications for disaster recovery, availability, and so forth. This white paper explains why migrations are useful, the methods that vSphere makes available for you to manually move a virtual machine (VM), and how vSphere can automate the process for you in various scenarios.

Michael Scarborough and Ryan Ballmer, co-authors of Global Knowledge ITIL courseware, discuss how to become an ITIL expert.

With VMware's recent release of the Horizon Suite (specifically View 6), VMware has taken the performance and usability features and put them all under the Blast moniker. This category of features is grouped from a marketing perspective but will retain their technical terms in the documentation, similar to how the term vSphere encompasses both ESXi and vCenter. Learn about the various features of the components that comprise the Blast family, including a brief discussion of what they are, improvements in version 6, and any notes or requirements for implementation.

VMware Horizon 6 was announced in April and began shipping in June 2014, bringing a more unified suite delivering more integration with infrastructure and cloud products and more simplicity for all devices.

He will highlight the benefits of integrating them into a single implementation program to avoid project disaster. Discussions are focused on "Getting Your House in Order" and how to establish your own organization-specific business transformation program, while increasing your organization maturity.

Cloud computing enables development teams to get applications into production faster. IT Service Management (ITSM) leaders must adopt new strategies and change existing processes or risk becoming a barrier to success. Cloud computing requires DevOps-the blending of development and operations with the goal of accelerating time-to-market and reducing time-to-value. The good news is that ITIL® is uniquely positioned to accelerate DevOps, but it requires changes to existing ITSM processes.

This paper is aimed at IT professionals who are interested in earning a VMware Certified Professional on Data Center Virtualization (VCP5-DCV) certification. It provides the benefits of having the certification, details for earning the certification and tips for passing the exam.

In 2013, VMware announced VMware Virtual SAN (VSAN), which is VMware's native version of Software Defined Storage (SDS). It is simple, easy to setup and managed by user-defined policies. This paper explains VSAN, its basic requirements and how it works.

The technologies examined reduce operational expenses (OpEx), not capital expenses (CapEx) that has traditionally been the focus of virtualization. Many companies implemented virtualization with the goal of saving money in the form of fewer servers to buy with a side benefit of reducing the footprint of the servers and lowering the required power and cooling. Most of the savings were in capital, but do not expect the same with many of the technologies listed here, because some may even require some additional capital expenditures, at least for software, in order to save on the day-to-day operations of IT. The bigger cost in running an IT department is in the OpEx category anyway, so savings there are recurring.

If you have been working with vSphere 5.1 or 5.5 lately, you have undoubtedly noticed that the latest features such as XvMotion and vSphere Replication are only available on the Web Client. This cheat sheet for the new Web Client includes instructions for configuring VMs, networking, storage, resource settings, cluster settings, permissions, and many other settings.

Michael Scarborough and Ryan Ballmer, co-authors of Global Knowledge ITIL courseware, discuss why ITIL is important to businesses.

vSphere 5.5 is now available with myriad small improvements such as a faster Web Client, LACP, Autoscale and higher configuration maximums. In addition, there are changes coming such as VSAN, which may be ground-breaking in regard to VM storage of the future. Since the release of vSphere 5.5, they have not yet announced a change to the blueprint for the test. That being the case, I will say, for now, that the VCP-510 test should remain unchanged as well. My goal here is not to reeducate you on everything that you need to know for the test; instead, it is to point out the few changes that might apply in your company or organization.

VMware vCloud Director fashions the provisioning of the software-defined datacenter layer to allow for a full virtual datacenter deployment within a short period of time. A vCloud consists of many layers and can quickly become a complex architecture. Before any deployment, requirements should be defined so that the vCloud can be designed to offer those services needed. It is imperative to understand the many components of vCloud, how each vCloud construct fits, which allocation models are available, and what network options can be chosen.

Traditionally, ITIL and TOGAF professionals have been part of different teams within an organization. Due to the ongoing alignment of business and IT, these professionals now often find themselves on the same team. Because of this crossover, there is a growing trend towards organization of work based on multiple best practice models. 

Many I&O leaders and customers see little value from investments in ITIL. Not getting the Return on Investment (ROI) you expect normally comes from using ITIL incorrectly. You, your staff, and your customers must share the same goals and understand exactly what to expect from your ITIL investments. The goal of ITIL is not “business and IT alignment” or “competitive advantage from IT investments.” Instead, its first goal is to stabilize service operation. This builds a base for the second goal: increasing value through service optimization. You must have clear-cut, documented, and managed expectations for each activity, and order is vital. Success requires that you stabilize service delivery before trying to optimize. Focusing on the correct goal and linking each ITIL task to that goal is the correct use of ITIL.

With the growth of bring your own device (BYOD) and mobility, users are increasingly asking for computing anywhere from any device at any time. Users now expect productivity on the go with a desktop that can be freely accessed and secure. We're no longer a society that sits at a desk to be productive. The VMware Horizon Suite allows the datacenter administrators to satisfy the accelerated mobility needs of the workforce while still maintaining an IT solution that is easily managed and secure.

ITIL is generally not prescriptive. In reality, the CSI Register at any given organization might look significantly different than the example given in the CSI book. The fields given in this example are important. 

Resource Pools are often misunderstood, disliked, and untrusted by vSphere Administrators. However, resource pools can be very useful tools for administrators who want to configure resource management without having to individually configure each VM. This leads to the administrator’s desire to explore the proper usage of resource pools.
