    Hello All,

    I get the below error while creating VM Instance. Did anyone get this? Or did I select the wrong Zone.

    "Quota 'SSD_TOTAL_GB' exceeded. Limit: 100.0 in region asia-south1."

    Size that I selected is : 200 GB


    Thanks,
    Ashish

    As I said in the session please select 20 gb approx. You don't need any more space than this.

    OK thank you, Siddharth! It worked. I hadn't noted this one, just followed what's there in the document.

    However.. "sudo apt-get install maven" command which is mentioned in the document didn't install maven properly. Good that I had noted the command during session i.e., "sudo apt-get install maven --fix-missing" which helped. Now, all is well :)

    Regards,
    Ashish

    From Class: I have few queries:

    1. As per arch. we discussed in class using Docker (instead of Hypervisor) : Guest OS installation layer is removed.
    Then under what business use case is the guest OS installation required (Is there any drawback of using Docker and rather Hypervisor could be suggested as part of Arch. solution)?

    2. When we created google image inside bucket (from tar zip) in Class Practice 1, it holds various resource information which gets realized when instance gets created through VM Instance. Is that holds true for docker image as well or it doesn't holds resource information rather other set of info?

    3. Can we see what does Docker image contains inside or its in byte format? If yes, how?

    4. Under what business scenario should I suggest my IT team to go for Containerization instead of citrix machines?
