For women in IT, advancing your career can be a challenge in itself. In the Global Knowledge 2019 IT Skills and Salary Report, only eight percent of senior- and executive-level IT professionals are women. We have pulled data from our research that sheds light on the job roles, skills, challenges, certifications and experience of women in tech who have progressed to the highest levels of an organization.

No matter what book or manual you use to study for the CCNA examination, you will see various protocols and processes referencing an RFC. And, although frequently referenced, the RFCs are seldom actually included in the documentation. So, the logical question becomes...

ITIL describes a service portfolio as a collection of the overall set of services managed by a service provider. A service portfolio describes a service provider’s boundaries and promises across all of the customers and market spaces it serves. I like to think of a service portfolio as describing the past, present, and future collection of services offered by a service provider. The figure below shows a high-level view of a service portfolio.

The advantage—and disadvantage—of IaaS cloud computing is complete control. The user is responsible for sizing, installing, and maintaining operating systems and applications, backing up the systems, etc. This enables the user to configure everything in an optimal way for the workloads that need to be accomplished, but it requires time and effort to determine how it should be set up, secured, etc. With the goal of providing a good place for you to start your IaaS implementation and highlighting some areas that you should plan for and design for, Global Knowledge instructor John Hales provides a review of IaaS, as well as insight into what you need to know before implementing IaaS. He also shares a laundry list of things to consider when implementing IaaS, including questions to ask yourself, your company and your potential cloud provider.

There are many considerations in deciding on whether to provide Software as a Service (SaaS) to others or whether to become a consumer. This white paper will explore what questions and factors you should keep in mind as you seek to implement SaaS. Considerations include deciding how your application will be accessed, implementing disaster recovery, scheduling platform maintenance and upgrades, handling service outages and creating a security plan. This knowledge can be useful whether you are provider of SaaS applications or are planning to be a consumer using software for activities like accounting or project management.

There are many questions you should ask before selecting your PaaS provider. Learn what you need to know in order to compare and contrast PaaS with the other offerings like IaaS and SaaS, and what they require in terms of setup and configuration. As with any decision involving IT infrastructure there are many variables that should be considered to ensure you find a solution that will fit your current and future needs, budget and support requirements.

While the recent trend towards cloud computing might make it seem like virtualization is new, it has existed in some form for many decades.

Many people believe that cloud computing requires server (or desktop) virtualization. But does it? We will look at using virtualization without cloud computing, cloud computing without virtualization, and then look at using both together. In each case, we'll look at where each deployment might be most useful, some use cases for it and some limitations.

One of the many useful features of tunneling is to carry non-IP traffic across an IP network, and this is still the case when dealing with IPv6 traffic. This transition mechanism makes use of a configured tunnel to transport IPv6 over a native IPv4 network, which may consist of two sites or more. Unlike the previous transition mechanisms, tunneling is not monolithic; while the basic principles may be similar, the operations are different. The following chart gives a breakdown of the current, major tunneling types in use, particularly in a Cisco environment:

There is a wide-range of services available in GCP ranging from Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) to completely managed Software-as-a-Service (SaaS). In the first part of this series, we will discuss the available infrastructure components and how they provide a powerful and flexible foundation on which to build your applications.

Google Cloud Platform (GCP) is Google’s public cloud offering comparable to Amazon Web Services and Microsoft Azure. The difference is that GCP is built upon Google's massive, cutting-edge infrastructure that handles the traffic and workload of all Google users. There is a wide range of services available in GCP ranging from Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) to completely managed Software-as-a-Service (SaaS). We will discuss the available infrastructure components and how they provide a powerful and flexible foundation on which to build your applications.

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.

Explore how IT decision-makers’ training views have changed since we first released our annual IT Skills and Salary Report 12 years ago. Once viewed as an expense, IT leadership now sees professional development as an investment. Even with shrinking budgets and a recent rise in skills gaps, the value of training is currently at an all-time high.

It’s been about 10 years since public cloud offerings like AWS opened up the world of big data analytics. This post examines the top five most useful architectures used for big data stacks to learn the sweet spots of each.

If you’re looking to fortify your cloud expertise, there are a number of certifications to consider. We have compiled 10 cloud certifications that are sure to positively affect your career. 

Technology trends such as these show no signs of abating, and IT administrators need to be prepared. Having a well-rounded and versatile team of IT practitioners is becoming increasingly necessary. In the following article, we examine five key skills that every IT department should have covered, regardless of the size of the company.

IT professionals benefit from gaining skills in data analysis, cybersecurity, cloud computing, virtualization and hyperconvergence, and mobile app development.

You might already know what cloud computing is, and you might already be implementing it into your business, but are you able to have a conversation about it? The lingo surrounding this newer technology can be a bit, well, cloudy. Here are just some of the terms we keep hearing as cloud computing spreads from organization to organization.

These technology job roles are proven to be essential during a crisis as enterprises scramble to change strategies and meet goals. The skills demonstrated by IT professionals in these 10 positions can make the difference between business success and failure, especially during a recession.

Amazon Web Services (AWS) offers increased agility, developer productivity, pay-as-you-go pricing and overall cost savings. But you might wonder where to start, what pitfalls exist and how can you avoid them? How can you best save time and money? Learn what you need to know and where to start before launching an AWS-hosted service.

As with all technologies transforming the way organizations operate, it’s expected that roles will also evolve. Cloud computing already has and will continue to change traditional IT roles and functions for years to come. We'll begin our overview of the transformation of cloud job roles with a look at some of the top cloud computing roles and responsibilities for architects, engineers and developers.

We spoke with Doug Cutting about his role with Cloudera and learned more about Big Data, training options for IT professionals interested in Big Data, and how Cloudera compares to Red Hat.

For 10 years, Global Knowledge has surveyed IT professionals and published the findings in our annual IT Skills and Salary Report. With topics ranging from top-paying certifications to most in-demand skills, our reports have consistently provided a deep examination of the attitudes and opinions held by IT professionals around the globe. With a decade of reporting at our fingertips, we decided it was an appropriate time to dissect the views of those making the decisions in the tech industry. What are their biggest challenges? How have their training opinions changed over time? How do their actions affect staff?

As IT departments struggle with skills gaps and businesses attempt to recovery economically from the COVID-19 pandemic, these 10 IT skills are essential to drive success. Job roles in these areas pay well, but decision-makers are struggling to find qualified candidates. If you’re looking to make an IT skills investment or start a new career path this year, these are the areas to consider.

In the digital age, people and intellectual property have supplanted physical assets as the most important criteria for determining the value of an organization. It is the employees who develop the next big product or improve the practices, processes, services and internal culture that add significant value to an organization.

Young adults unable to find work, employers unable to fill jobs, a recent GAO study that reported substantial declines in telecommunication expertise — there has been a lot of news about the pervasiveness of skills gaps, their causes, the actual impacts and what to do about them. It’s rather confusing, because the term “skills gaps” has been hijacked to politicize an extremely wide range of issues.

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.

This white paper has three main goals. The first is to generate a better understanding of the cloud in both the business and IT communities. The second is to describe the major components of vCloud and the virtual datacenters they provide. The third is help businesses visualize and understand how vClouds could be beneficial in addressing their specific IT needs.

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.

In a recent post, I gave an overall description of a service portfolio and the key components of a portfolio. Here, I will describe how a cloud services provider might implement an ITIL service portfolio. A cloud services provider will regularly have a set of services under development, a set of service in live operation, and a set of services that are retired.

As mentioned in last week’s post, interviews that require ITIL Intermediate level knowledge will most likely be targeted to specific process areas and activities. If I interviewed someone for a job that required ITIL Intermediate level knowledge, in addition to other questions about the specific technical responsibilities of the job, I might ask the following questions:

After a review of Software-Defined Networking (SDN) and its close cousin Network Functions Virtualization (NFV), this white paper addresses three main deployment scenarios: SDN without deploying cloud computing, cloud computing without deploying SDN, and deploying cloud computing in conjunction with SDN. We'll look at use cases, when the approach makes sense, and any applicable limitations.
