Note: You do not need to actually create a local VM or AWS, only answer Question
Note: You do not need to actually create a local VM or AWS, only answer Questions 1-8 at the bottom.
Part 1: Create a local VM:
VirtualBox from Oracle for your OS may be downloaded at:
https://www.virtualbox.org/wiki/Downloads (Links to an external site.)Links to an external site.
Once your VM is turned on and functioning:
From VirtualBox, click Machine>Take Snapshot and provide a name/descriiption and click “OK”.
The snapshot name and a short descriiption can help you identify why a snapshot was made, when, and why. Including this information is a common recommended practice, as it makes managing multiple snapshots easier
From VirtualBox, click Machine>Take Snapshot and provide a name/descriiption and click “OK”
The snapshot name and a descriiption can help you identify why a snapshot was made, when, and why.
On the desktop of your VM, create a file, folder, or any other artifact that is visible on the desktop.
If you’re doing a purely CLI based VM, create a textfile in a directory you’re able to access
Power off / Shut down your VM
In VirtualBox in your “Oracle VM VirtualBox Manager” select your VM in the left column, and click the icon with three squares and three rectangles.
Click Snapshots
Select the Snapshot you took in step A and click “Restore”
Power your VM on
Look for the file created in step D.
Look into Virtual drivers
Modify one of the drivers, such as the network driver
Use the internet in your virtual machine
Then disable the driver
(DOES NOT NEED TO BE ANSWERED, just to think about)
What happens to the internet connection?
Can you still use the internet on your host machine?
Reactivate the driver if necessary
Install some software of your choice
How is the installation process?
Were there any limitations?
Did you run into any issues?
Share files between host and virtual machine
What’s the process like?
Any issues?
What are some potential issues?
Part 2 Create and Access and EC2 instance on AWS:
Create an account on AWS for their Free tier, and follow this guide: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EC2_GetStarted.htmlLinks to an external site.
Create a Windows Server 2022 instance using their Free tier Windows Server 2022 AMI. Note: THIS WILL BE SLOW. We are using the absolute bare minimum resources to create it in AWS’ free tier.
Answer the following questions in your submitted document.
[Q1] Express what the effect was of taking a snapshot before a change, and restoring to a snapshot after a change was made. Your answer should explain why the file created in step b) is gone, and what the effect of restoring to a snapshot from before you created the file was (3-6 sentences expected)
[Q2] How might a software developer use this functionality when developing or testing a new system? (3-6 sentences expected)
[Q3] How might a system admin use this functionality in the course of their job when applying a new update, firmware, or feature deployment to a virtualized server or environment? (2-4 sentences expected)
[Q4] What were the system configurations you gave your system (Memory, Storage, Processor(s), etc)? Why those values? What were the limiting factors in not provisioning the virtual machine with double, triple, or 10 times that amount? (3-5 sentences expected. You may use a list to enumerate the system resources)
[Q5] How do virtual machines utilize virtual drivers, and what’s the impact of altering these drivers within the virtual machine, both on the virtual machine itself and the host machine? Are there any common issues that arise from such modifications, and if something goes awry, what are the steps to rectify the situation, or better yet, how can one prepare to prevent issues? (2-4 sentences)
[Q6] How does the file-sharing mechanism between virtual and host machines operate, and is there synchronization when modifications are made on one side, or is there a separation, and why does it exist? (2-3 sentences)
[Q7] AWS: What was different about the process of setting up a VM in VirtualBox (or your alternative) and AWS? What was different in how you navigated your on-machine VM vs AWS? (2-4 sentences)
[Q8] AWS: Did you shutdown your AWS instance? If not, GO DO IT! You pay as you go, and the free tier can burn your ‘credits’. Why is it critical to manage your spend in cloud environments for deployed/created systems? (1-3 sentences)
