Why is the Virtualized environment is better than the Physical one ?

• Scalability. Rather than having to buy new hardware every time you need a new server, you’ll be able to “spin up” a new server in far less time (and for far less money).
• Efficient use of resources. Most physical servers only run at 25% capacity, which leaves plenty of leftover memory and processing power. With virtual servers, one physical server will be “hosting” multiple virtual servers—so you’re getting much more out of that one host (and that one investment).
• Minimal downtime. If you have to work on one of your host servers (adding memory, for example), you can simply move your virtual servers to a new host, perform the required maintenance, and move them back with no interruption to your services.
• Disaster recovery. It’s much faster and easier to restore a failed server in a virtual environment. You can also easily build in a second Storage Area Network (SAN) that replicates all of your data and gives you far more robust on-site recovery capabilities.
• Simplified management. Hypervisors will allow you to log into one server and manage all of the servers in that environment. You’ll also get more in the way of statistics and reporting than you would from a physical device.
• Security. Security is centralized through the hypervisor software; instead of securing each of your individual servers, you just have to focus on building proper safeguards and controls into your underlying software. 

Flexibility is major advantage, you may easily migrate vm to other server or storageso Hardware Independence 

My experience is neither is better than the other there pros/cons to each.  a Virtualiised environment has a reliance on an infrastructure for example. Stand alone can allow for more flexibility - for different uses for different purposes.

Thankx for inviting me to answer. In my opinion there are many reasons to prefer virtualization over physical. Flexibility is major benifit. Easy to move migrate adjust the resources live most of the time. Dynamic resourse managemnt by the controller. This will utilize the resources according to the demanding workload. Backups and recovery are breez, fast easy and relible specialy when used with backup solution.

Ease Administration and Management, Very Less Downtime, Easy Maintenance and Backup,Effective utilization of resources.

1-

 Performance – Physical servers have the edge

2-

Cost savings – It’s a volume game

3-

 Disaster recovery – Easier in virtualized servers

4-

Security – Better in dedicated servers

5-

 Infrastructure Scaling

6-

Management Time

 

Virtualization is much preferred due to following.

1 Zero downtime for HW maintenance

2.Easy Snapshots for data restoration.

3. Easy Cloning,

4.Faster setup of new server,

5..Superfast storage migrations.

6.HW efficiency.

7.Lesser carbon footprints.

 

Above are some of the features which makes me chose virtualization and of course are not limited to these.

One should understand that by working in virtual infrastructure we are reducing the carbon footprints. We are working towards the Green-IT, thereby reducing the green house effect. Earth will be better place if most of the things will be moved to cloud.

Cost Cutting, Easy Management, Physical space reduction,etc

1.     Well isolated environment.

2.     Low coast to manage upgrade and resources efficient.

3.     Easy to backup restore migrate to other environments with different specifications.

4.     Automatic startup sequence.

5.     Included firewall into hypervisor itself.

 

Virtual environment pros:

1-Cuts down cost for physical hardware needed.

2- Maintenance cost for hardware goes exponentially down.

3-Management becomes centralized.

4-Easier to grow as your needs keep growing.  

Cons: 

1- Type 1 hyper visors ( like ESXi servers ) have less chances of failures but that's not to say that don't fail. That is why they have features like VMotion. 

2- If the virtual environment fails even with the redundancies in place, then you loose more than one server. where as in physical servers / environment one hardware failure means only one machine is down.
