As a sales, in the face of the different needs of customers, in order to better solve the customer's different problems, and the advantages of the product display, so determined that I also want to learn VMware virtualization and cloud services.
First of all, the customer is often asked some questions about virtualization? As follows:
1. Is the virtual machine stable?
2. Why use virtualization?
3. What benefits can virtualization bring?
4. The host is broken, is not all virtual machines can not use AH?
5. are virtual machines easy to manage?
6. can I migrate my current physical machine to a virtual machine?
7. How does a virtual machine back up?
In order to better solve the customer's problem, I also asked the degree Niang many questions, the following simple answer:

Question one: is the virtual machine stable?
A: Stable, VMware virtual machines are created on the Esx/esxi, and Esx/esxi are based on the Linux kernel, so the relative security and stability is better than the Windows system, then we need a lot of Linux basic knowledge, I personally feel no need, because just the kernel based on Linux, we just need to esx/esxi some simple settings are already fully OK, such as: IP address, user name and password.
Question two: Why use virtualization?
A: Unless your company is only a simple one or two servers, otherwise I think there can be considered virtualization, to the current server hardware resources, simple to do an ad server, file server, OA server, official website, financial server, Lync Server, two words "waste", single CPU usage is always in 2 %--3%; Buy a 16-core server, memory to 64GB, hard disk to do a RAID5, I believe that all of the above service applications installed on the virtual machine, performance is not a problem.
Question three: What benefits can virtualization bring?
A: summary: "Five provinces"---save costs, save space, save electricity, save the renewal fee, save manpower.
Problem four: The host is broken, is not all virtual machines can not use AH?
Answer: This is true, is not a great risk ah? A matter of opinion, but I think there is no need to worry too much, as if 10 years ago a customer said, why to go to the ad to manage the client, if the ad is broken, my next machine is not miserable, but a year later, he still on the AD domain control, the situation is the same; to avoid risk, We can back up the files of the virtual machine, restore, directly put the files on another ESXi can be run directly, do not rest assured, get a virtual ESXi cluster, this is safe enough.
Question five: are virtual machines easy to manage?
A: It's easy to see the usage of all virtual machines and graphical operations through vsphere VCenter.
Question six: Can I migrate my current physical machine to a virtual machine?
A: Yes, VMware provides a tool specifically for migrating physical machines to virtual machines, and is a "0" risk, and the data and applications of physical servers are not lost at all, and migration is like cloning.
Question seven: How do virtual machines back up?
A: There are many ways to back up, as if you had previously backed up a Windows server, you can also do a file backup of the virtual machine directly, see what you really need.
Answer a lot of questions, maybe you have a lot of questions, but I believe that through each of the following series, you will slowly understand the benefits of virtualization, and solve your doubts.
Please look forward to the next chapter: one of the Sales VMware Learning Series----ESXi installation steps
