Do I Need to Keep ISO File for Virtual Machine?
When setting up a virtual machine, one of the first questions that might come to mind is whether you need to keep the ISO file. This is a crucial question, as it can affect the performance and security of your virtual environment. Let’s delve into the various aspects to help you make an informed decision.
Understanding ISO Files
An ISO file is an archive file that contains the contents of an optical disc, such as a CD or DVD. It is commonly used to distribute software and operating systems. When you create a virtual machine, you often need to provide an ISO file to install the operating system or to run a specific application.
Why Keep the ISO File?
There are several reasons why you might want to keep the ISO file:
-
Backup: Keeping the ISO file ensures that you have a backup of the installation media. This can be useful if the original disc is lost or damaged.
-
Multiple Installations: If you need to install the operating system on multiple virtual machines, having the ISO file allows you to do so without the need to insert the physical disc each time.
-
Customization: Some ISO files contain custom installations or additional software. Keeping the ISO file allows you to apply these customizations to your virtual machines.
-
Security: By keeping the ISO file, you can ensure that the installation media is not tampered with or corrupted.
When Not to Keep the ISO File
While there are advantages to keeping the ISO file, there are also situations where you might not need to:
-
Single Installation: If you are only setting up a single virtual machine and do not plan to use the ISO file for future installations, you might not need to keep it.
-
Secure Environment: If your virtual environment is secure and you trust the integrity of the installation media, you might not need to keep the ISO file.
-
Online Access: If you have access to the installation media online, such as through a cloud service or a network share, you might not need to keep the ISO file locally.
Storage Considerations
One important factor to consider when deciding whether to keep the ISO file is storage space. ISO files can be quite large, especially for operating systems like Windows or Linux. Here’s a table comparing the sizes of some popular ISO files:
| Operating System | ISO File Size |
|---|---|
| Windows 10 | 3.5 GB |
| Ubuntu 20.04 | 2.5 GB |
| CentOS 8 | 4.5 GB |
| Oracle Linux 8 | 4.0 GB |
As you can see, the size of the ISO file can vary significantly depending on the operating system. If you are working with limited storage space, you might want to consider the impact of keeping the ISO file.
Conclusion
In conclusion, whether or not you need to keep the ISO file for your virtual machine depends on various factors, including the number of installations, the security of your environment, and the available storage space. By considering these factors, you can make an informed decision that best suits your needs.
