Useful Virtualization Tips That any Network Administrator Should Pay Attention to

The virtualization tips can reduce costs, facilitate management, and empower an organization to maximize its productivity. Below will help you to benefit from the tips From small to large enterprise services .Virtualization has become a necessity for all companies of any size virtualization, virtualization helps make more of its own hardware, and these hardware can do more for This technology is quite new for many companies, but for the rest it's .companies than the former Regardless of where you are, virtualization is a widespread technology with many moving .outdated Having the knowledge to do the best in order to fit your needs should be your primary goal and your parts Taking this idea into account, we will look at 10 tips for virtualization that should not be ignored by network

     IT teams of course, we mean those network administrators who have just taken this technology into administrators account, or have already carefully reviewed it

01- Capacity plan Virtual the of Hard increasing:

When you are in the early stages of planning your virtual environment, do not buy the hardware incorrectly, Remember that .In this area you need to think too much .which can not handle the load that virtualization puts it your server may host multiple virtual machines, so it should have the initial power and the space it needs to Measure the capacity twice, by .Eventually you need a hosting server that is specific to virtual machines .grow Do not assume that a virtual machine occupies a small amount .applying any virtual machine, reduce the capacity And do not assume that your server is the only host of a virtual machine of space on the server.

02- Track the lifetime of any virtual machine:

I have heard from some network administrators that they have left a virtual machine with little or no supervision You should also always know about  .You have to track all your virtual machines from the start .to do their job how much virtual machines have expanded, what's their current status, how much traffic they have, and what It's a very tempting thing to say: "Set up and forget" virtual machines, but this is a .other information you get Monitoring software will show you how much bandwidth .gross mistake and can put you in a world of problems you use with each virtual machine, and you will easily identify and manage the machines that have the most network traffic.

03- Do not virtualize anything:

Probably? Is it FTP server that only receives multiple internal users traffic .Everything should not be virtualized You need to create a specific program and decisive reasons for everything that is  Not probably ?Print Server .no When you were able to ?The first thing to ask yourself is "Why do I need to virtualize X Server. virtualized answer this question a little bit confident, use the same argument for any server that you think would benefit from virtualization.

04- Monitor virtual traffic as non-virtual traffic:

Feel free to think that virtual hosts are safer, Make sure you monitor virtual traffic like your non-virtual traffic This is a false sense of safety and should not .simply because you can instantly control their status with an alert You need to know the internal .But surveillance goes beyond security .be considered as a substitute for security After a certain period of time, you will know if there is a need to and external traffic of your virtual machines give more resources to specific machines, and whether other virtual machines can be independently served

05- Do not give virtual resources for free:

I have seen many times: virtual machines that seem to occupy little space are easily available in a "free" area Customers need to .Do not even change a server for free from standalone to virtualized mode .not do this Virtualization comes with all the benefits that comes with .understand the benefits that a virtual server gets Additionally, the technology required for virtualization has related costs, and sometimes these costs are it  Your organization can not bear these costs alone high

06- Use virtual machines for disposable systems:

This may seem a bit strange to some people, but there are times when you temporarily need a system or  need a In such cases, there is no better way to provide a temporary service with virtual machines service Virtual ?Need a print server or temporary web server .Virtual machine is working? temporary FTP server a good point about virtual machines is that their hardware resources do not cost you, so machine is enough. You can even create specific virtual machines for "disposable tasks" and enable making such a machine is easy.

07- Use bulk drives when performance is important:

For those virtual machines that  .Most administrators create dynamic volume drives for their virtual machines In other words, set a real size for the disk in the  .need to be more efficient, you need to allocate massive drives Yes, you need to make the necessary planning so that the host machine has virtual machine configuration. But the performance of this work is definitely worth it when you enough space to service the virtual machines spend it.

08- (Guest and install virtualization) (All development tools for guests):

Most virtual machine tools (such as VMware and VirtualBox) provide guest-development tools .This is inevitable and other virtualization tools designed to enhance experience and performance as well as integrated guest and But you .Many managers neglect to install these tools, assuming they are unnecessary .host communication Mouse integration tools, display drivers, guest-to-host time-alignment, and other tools can be .install them Although not necessary, they are useful for improving installed to help make the virtual machine more efficient end-to-end utilization. 

09- Keep your host system up to date at all times:

Although this is true for the virtual machine,  .Most people think that all the pressure on the car is on the guest car The last thing you need to do is create your virtual machines  .the host also plays an important role in this process If this server does not host multiple virtual machines, then the only thing that is at stake  .on a vulnerable device But since the server hosts a number of virtual machines (some of which can  .is surely the server's valuable data For this reason, you need to make sure .be owned by customers), the threat of data loss increases significantly 

the host is up to date and always safe.

10- Use a comprehensive way to monitor virtualization infrastructure:

The uninterrupted and comprehensive monitoring of virtualization infrastructure is very important, especially in cases where the number of virtual servers is high, you can not control the health and check the status of each system manually and manually, so you There is a need for a specialized way of monitoring 24-hour virtual servers, which will inform you in real time of any kind of problems, comprehensive monitoring system and data center will provide everything you need for this.

Conclusion: 

At that time, you should be as prepared .Your company may want to invest in virtual technologies at a time.

Note that with the effort and diligence that is required, virtual machines save your money, time and 

effort. As which ultimately will satisfy your customers possible.
