Guys, I need to choose a technology to further my studies. Honestly, I don't know if I should focus on more traditional hypervisors, or consider something a little different like containers, clouds, etc., or even, of these traditional ones, which would be more interesting to focus on? We're seeing vSphere being migrated to KVM, Proxmox, Nutanix, and others. Which of these hypervisors that are being used instead of ESXi do you think will take off?
This is a personal question for you. I know no one has a crystal ball, but your experience certainly counts.

Thanks for your help, I’ll appreciate that!

Hey ​@AndrePulia -

I guess the first question is...what technologies do you think you lack in? For example, do you think you need to dive deeper into Linux? If so, I can wholeheartedly recommend trainings on Pluralsight by Andrew Mallett. For hypervisors...I’ve dove into XCP-ng the past several mos and have enjoyed it. Is it perfect? No. Better than VMW? No...but a worthy product for SMBs imo. It appears SMBs are diving into Proxmox too. So that may be another h/v to look at. Those are just some of my suggestions. If I think of anything else...I’ll share it. Good luck! 🙂

This is very subjective and there will be many answers.  What technology are you passionate about?  That might help to start narrowing the focus down.  Is there something you focus on daily and want to learn more about or in the case of something like VMware VCF 9 there are many paths you can follow here with all the applications within the suite.

I myself am getting more into Kubernetes due to us deploying VCF9 and that will lead me in to working more with Kasten which I have not as yet so need to start learning that.

This is a broad path so narrowing it down can be hard but technologies you use daily or are passionate about can be expanded.

Preface: noone can replace 10.000x FTE from VirtZilla from 0 to Hero. They did -something- and its therefore its valueable. The big question - who needs the “Bells and Whistles”. I see two trends here: 

  • 1 / Cloud native NEW software development will run sooner or later on K8s - might be very questionable for e.g. RDBMS, but it is like it is - the market has spoken
  • 2 / Who needs the “Bells & Whistles” from VirtZilla - imo XCP-NG and Proxmox are very much on the rise out of very good reasons

I had this question before and I felt I had a good knowledge on vSphere/Hyper-v and Windows in general, so I redirect my studies to Cloud. This was 3 years ago and now I fell I have a good knowledge on AWS and Azure.
So, for me was basically a combination of Shane and Chris answers. I lacked the knowledge on Cloud and also I like the subject, so it was a easy choice.

Also it depends on what is easier to access to study. Cloud was easy because you can just create an account and test it. Althought it costs money, it's easier to start.
But with Nutanix, for example, it's more complicated to create a lab because it demands a lot of resources.

Hi ​@AndrePulia 

Although many people are talking about abandoning VMware, its solutions will continue to exist for a long time to come, given the reliability that the virtualisation platform has achieved over the last 20 years.

It also depends a lot on the market you work with. If it's small or medium-sized businesses, they may be more inclined to save money, but you have to see where to migrate. For me, Proxmox is not yet ready to welcome my customers. If someone asks me... then I'll take them there.

I think here in Italy, the SMB market is still uncertain and has a small budget, so they try to find something cheap, but I can guarantee you that they look for savings on other items and not so much on the hypervisor (at least my clients do).

Personally, I’m growing my skills in the Azure world. 

My 2 cents.
