CBT Nuggets Trainers Talk Virtualization
CBT Nuggets trainers Bart Castle, Jacob Moran, and Jeff Kish recently held a virtualization-focused tech panel. During the 1-hour event, they discussed the latest industry news and trends, explained core virtualization topics, and answered questions.

Here's a bonus Q&A featuring questions the trainers weren't able to get to before the end of the tech panel. Enjoy the additional insight and advice from Bart, Jacob, and Jeff.
Which technology to study first? Cloud or Virtualization?
Cloud computing is not so much a technology as it is a service-delivery mechanism. It's a way for organizations like AWS and Azure to make technologies like virtualization available as-a-service, predominantly a service which you pay for in an on-demand model. That being said, virtualization is a core element of making cloud computing possible, it is a good part of a well-rounded IT training portfolio. At a bare minimum, a CompTIA A+ or Net+ level of understanding of virtualization will be sufficient to begin studying for cloud certifications.

Is there any technology to replace cloud nearby and which technology is paying high in the market?
Cloud computing is an umbrella term for IT operations delivered-as-as-service. This means that as IT evolves, network-accessible services (aka cloud services) will continue to be the standard until the nature of how we interact globally over the internet changes. One of the most important facets of IT and cloud is increasingly security – I encourage learners to add security to their balanced diet of training. It's unlikely that the cloud will be replaced, but we can rest assured the tools we use to support cloud workloads will evolve and constantly require some level of integration and customization, consider those job opportunities.

For mid-level IT managers like me, should I focus on technical certifications or go for management certification?
This depends entirely on what you want to pursue in your career. If you find yourself passionate about how to use technology to better enable business processes, you enjoy conversations around budgets and financial planning, and you enjoy managing people, you should pursue a career in IT management, which may one day lead to a CIO position. If, however, you love being at the CLI, you're most satisfied when a configuration comes together, and you want to explore new technologies as soon as they're released, then a technical path is right for you, which may one day lead to an Architect or CTO position.

What skill do you see being most useful to learn over the next 3-5 years?
This is Jeff's opinion (so gather opinions from others as well), but programmability is among those skills that will be most highly sought over the next several years. This isn't just a knowledge of coding languages, but an overall understanding of how to automate systems that have long been manually configured. Pursue skills in scripting languages such as Python, as well as automation tools such as Ansible, and you'll be setting yourself up for success.
— Jeff Kish
What is the best virtualization route? VMware, Hyper-V, KVM, etc?
The best virtualization route is the one in which you have the tools you need for now and in the future. Often that means looking at the options available for integration and automation because those will be limiters, as well. The good news is that if, for example, you have Microsoft licenses and start with Hyper-V you will learn the virtualization skills that apply across all platforms, such as VM files, snapshots, migrating VMs from one host to another, monitoring host resources, etc.
— Jacob Moran
What is the future of virtualization? What is the security aspect of virtualization?
The future is cloudy, so managing virtualization resources that are on-premise, in the cloud, or a hybrid of the two will be critical skills to learn. Likewise, the future is tiny — for reasons of security and performance. We see technologies like micro-segmentation, where the rules for ingress and egress are applied on a per-VM basis, not based upon their current subnet. And in a similar vein, we see the march of containers, where microservices are called upon to do one job, do it very well, and not be subject to the vulnerabilities that come with an entire operating system.
