    You are, by far the best teacher I have ever come across anywhere, online or in person of any IT topic. Man you probably don't even realize how big a service you are doing to folks like us who scour through reams of documents and large contents on the internet just to get a grasp of these topics. THANK YOU!!!

Please do keep posting more of those videos. Thank you so much for putting out a genuine work on UA-cam. Suresh, Ontario, Canada.

You indeed are the best teacher on UA-cam ! who follows the KISS principle..never bores.. and always helps me learn so much !

  • @elithecomputerguy
    @elithecomputerguy  13 років тому +1

    @KevinDR1987 Outside of a highly virtualized environment this is correct. This type of virtualization is built to work this way. The server instances are not shut down. It's the physical servers that get powered on and off.
    As an aside I understand what they are saying, but be careful of taking it too literally. You should maintain your systems to a degree that you are 99% sure the things will come back on if you do a reboot. Windows Server 2008 isn't NT...

    Most presentations, even lectures in real life, have zero redundancy and just blast through the material at incomprehensible pace.
    With yours, it's like... listen to it, okay, got it in one, woah. I actually understand the concept instead of just learning to parrot the words to describe it.

    This is a great video to learn the very basics of virtualization. I've been looking for something like this for weeks, everything seems to skip over the basics. I can now say I actually understand what a hypervisor is, before it was just a word I've heard many many times.
    It's a shame you're not the VMware CBTnuggets guy, you would rock!

    Hello Eli, in case you are still reading the comments on UA-cam.... I have a paper to write about virtualization, and so far, nothing is as clear as your videos to summarize all the information I am actually looking for. I will most definitely quote you in my paper, but if you have any suggestion for a book or another type of papers about the subject of virtualization, I would take it happily ! Most of the papers I found are very specialized, and the book I read about OS (and their chapter on virtualization) are most often only talking about the type 2 of hypervisor ! You made things so clear.
    Anyway, if you don't have time I still thank you a lot for your videos, you are a great story teller and that makes your explanations about computing beautifully accessible. Many thanks

  • @brownj0002
    @brownj0002 8 років тому +2

    The example of old NT servers is very good, but also older hardware costs much more if you maintain a service agreement. However, I think the part about the electricity costing $100 a year underestimates a critical point.
    I think the power demand for server boxes (non-bade) is more like $200-400+ per year, and can vary not just on your per-watt-hour cost locally but the CPU usage (so who knows?). That does not take into account the cost of *cooling* a server room/data center- and that also varies dramatically based on scale.
    I had seen projects where $5m in hardware meant a $4m facility upgrade (power and cooling) and about $3m per year to run both power and cooling. So by year 2 the "environmental cost" ($10m) was twice the cost of the hardware, making TCO like $15m. So virtualization applied to that project today might make it $2m hardware, $2m facility, and $2m AC+HVAC for a total of $6m ops ($8m TCO). That is an oversimplification but you can easily see the impact to a companies total cost of ownership, which is why it's been a big buzzword for like 7-8 years now. :D

  • @markkenter8123
    @markkenter8123 9 років тому

    I have been in IT for 18 years as a sys admin and the most important aspect of anything new in IT are the concepts. Yes, I understood basically what Virtualization is. I know what a Lun is. I know what a data store is. But some things I did not know. And when all these experts did their best at going over hyper v or VMware basics, they were not communicating irtulization concepts but were only communicating features of the software. So the concepts that I didn't know interfered with my learning. Not one person I met at these conferences was adequate at communicating basics. People, if you don't understand the basics, forget it. Also, never let your ego persuade you on learning from the most rudimentary level. Its one thing that has helped me immensely. I am never ever afraid to be a 1st grader all over again and in fact, I embrace it. Its actually fun. Eli is like a 1st grade teacher that I needed to find before I could move on. Now I have a much better understanding at going through the VMware hands on labs because now I understand the vital concepts. I really look forward in finding some more videos that Eli shares.

      mark kenter Professors, instructors are not your best friend. They're there to make money. If you ever challenge their intellect on different subjects, they'll be just as loss as you are, unless they're proficient in many subjects. You can always give them a poor rating if they are a a** hole professor/instructor.

    @Badboysvsgoodboys Supposedly if you buy the Server version of OSX you can do it... Their may be some hack to get the regular version to work but I don't know it. (One of the virtualization companies made a coding mistake last year that allowed you to create OS virtual machines, but they "patched" the "problem" and so you cant do it anymore...) I would go with VirtualBox if you're new to virtualization. It's free, stable, works on everything...

    Another benefit along with Server Consolidation is Resource Utilization..... With single dedicated desktop/server for one application you might not be fully utilizing the server's Compute (CPU, Memory etc) resources and when you virtualize the servers and OS and Apps in one single server you are sharing the resources thus fully utilizing the server's Compute power.

    Hey Eli, great vid! I was wondering, at about 24:00 in your video, you mentioned that in the event of a hardware failure, the instances can migrate over pretty much instantly. I have a couple of questions about that.
    1. From VMware's website, I read that in the event of hardware failure, the containers can be moved to another server, but the container needs to be rebooted. (Obviously much less downtime than migrating an OS in a non-virtualized environment)
    2. In order to take advantage of the migration service, you need a shared disk on the network correct?
    Unrelated to migration, what do you think the disadvantages of virtualization are?
    Lastly, I've tried reading about the difference between traditional on-prem services (i.e. cluster databases etc) vs private cloud. As far as I have been able to find, it seems that the only difference between the two is virtualization. Is there something I'm missing?

      www.vmware.com/products/vsphere/features/high-availability#sthash.Lolbohwg.dpuf
      2. Yes you will need a NAS or a SAN with a very high speed NIC
      3. It depends on what service you go with VMWare, Azure, AWS. That gets a bit complicated so honestly I'd have to do an hour of research just to make sure I'm giving you the proper information. You should be able to contact VMWare and ask them directly.
