How much does Virtual Machine spreading cost?

How much does Virtual Machine spreading cost? -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Virtual machines: they are easy to create, easy to deploy, and easy to spread without control. In the data center, the spread of virtual machines is a new problem, which increases the overall cost of your own virtual machines. The spread of virtual machines can also be referred to as virtual spread, which means the creation and deployment of virtual machines without proper total control. If a cost-saving technology is not well investigated, it will usually be a waste of money.

So how does the spread of virtualization cost you? Let's look at the cost factors brought about by the spread of three virtualization. It will tell you the answer to this question.

I. Copyright

Among the factors that cost us in software, copyright is the biggest and the most shocking part of the spread of virtual machines. These virtual machines are subject to the copyright cost of the operating system and applications. Generally, they are charged for each installation. Therefore, whether your VM is on or off, you must pay the copyright fee. If the operating system or application exists on a virtual machine, it should also be used. All the testing machines you created should be included.

You might say that you are using Linux and all the free software? If so, that would be great. You can directly look at the second factor below.

Solution: remove virtual machines that you do not use and release their copyrights back to the available copyright pool.

Ii. Space

Yes, I know it is the last line of defense of the data center. However, it is also a major cost factor for our business. Its capacity is always insufficient, and it is usually very expensive-I don't care how much you spend to pay for your GB MyBook. You know this yourself. When a default hard disk with a minimum size of 8 GB is used on a virtual machine, you will see that as the virtual machine is created, the space will be surprisingly changed. A gb hard disk will not last too long for 8 GB/virtual machine. That is, it can accommodate 31 8 GB virtual machines. So where do you put the backup again? How long can you keep them?

When calculating the cost of virtual machines, it should include the costs related to these virtual machines, images, and hard disks for backup. Do you need a 20 GB Virtual Machine for the desktop or a 4 GB space?

Solution: create a virtual machine based on your needs and minimize the disk space.

Iii. Time

You don't think it takes much time to manage virtual machines. In fact, it takes a lot of time to get rid of the spread of virtual machines. You may believe that all virtual machines can be recorded in some form. However, it is not easy to delete a VM from the disk if it is not removed from the disk. It takes time to build a properly recorded virtual machine environment, and time is money.

The best way to track whether a virtual machine is on, off, and can be queried or not is to use an automatic check process to lock the virtual machine. You can use this script to search for Disk Images and virtual machine configuration files to estimate the disk usage of these images.

Solution: save time by using the Automatic Virtual Machine "Search and report" script.

After you use these methods to reduce the number

After the spread of some virtual machines, How can you ensure that these situations do not happen again? 1. Create a copyright review system-you may need to use a review system to track copyrights so that administrators can use copyrights as needed. If your script indicates that some of your VMS are not currently in use, remove these machines and return their copyrights to the available copyright pool. Keep your software copyright under your control. Otherwise, you may need a painkiller tablet instead of a cup of champagne to celebrate when software copyright is reviewed.

2. define acceptable disk usage parameters for virtual machines-define acceptable size ranges for Virtual Machine disk usage. Limits on server systems, desktops, virtual machine swap/page file space, and personal storage. With predefined limits, you can accurately calculate the required capacity and predict new demands that change with growth.

3. Automated time-consuming tasks-use virtual machine templates to reduce the time provided by virtual machines, and automate repetitive tasks through the built-in APIs of your virtualization software or shell scripts on your host operating system.

The spread of virtualization increases your costs through software copyrights, storage space, and time. Do not make virtual machine creation simple and consume more costs. You need to take preventive measures so that you can truly enjoy the happiness of champagne.
