Types:

Software

·        
Operating-system-level
virtualization

·        
Application virtualization and workspace virtualization.

·        
Service virtualization

Memory

·        
Memory virtualization: aggregating random-access memory (RAM) resources from networked systems into a single memory
pool

·        
Virtual
memory: giving an app the
impression that it has contiguous working memory, isolating it from the
underlying physical memory implementation

 

Storage

·        
Storage virtualization.

·        
Distributed file system.

·        
Virtual file system.

·        
Storage hypervisor.

·        
Virtual
disk.

 

Data

·        
Data virtualization.

·        
Database virtualization.

Network

·        
Network virtualization.

·

Benefits:

 Reduce spending.
For companies that have less than a thousand employees, spend up to 40% of IT
budget on hardware. You Buy multiple servers is often a huge part of this cost.
Simulating needs  less servers and
extends the life of existing devices. Moreover , meaning of this is  reduced energy costs.

Easy disaster recovery and  backup. Disasters are quick and
unpredictable. Secondly , flooding
, ,leaks, ,power outages, hacking  attacks, steals and snowstorms can also wipe
out basic data to your business. Virtualization makes recovery much faster and
accurate, with less manpower, and part of the equipment – and all virtual.

Improve business continuity. With a growing mobile
workforce, good business continuity is essential. Without  this , folder  it becomes unreachable
and all the  work it goes undo, processes
are slow down and employee is unproductive. Virtualization giving  the employees access to programs, files, and
messages from anywhere and it  can enable
many  people to access the same the data  for more continuity.

Increased efficiency of IT operations. Going  to a virtual place can make everyone’s job more
easy  – especially IT staff.
Virtualization provides an easier way for technicians to install and maintain
software, distributing  updates and
maintain a high secure network. They can do this with less downtime and less
power outages, faster recovery and immediate backup compared to a non-virtual
environment.

 

 

 

 

 

 

 

 

 

 

 

 

Challenges and implementation:

 

1 challenge:

 

experiencing performance and availability-depleting resources

 

performance problems-often are created by the transition from
physical machines to virtual machines and the mouth of the saturation cause
network resources apply to Burnout at a much faster rate.

• the intensive of operations has tripping  into the translation layer default .

 •  all the Network cards saturation software(SW)
 switch which are  in the physical host is causes of performing
the troubles , less bandwidth,  and the increases
latency.

 

 

 Solution:

 

F5 Big-IP ® local traffic Manager ™ (has been) to unload
resources, including SSL and caching and compression

 

. • you can Use resources more efficiently by maintaining the
resources of mouth to focus on what they did best.

• Boosting performance by putting I/O –intensive networking
operation on hosts that were built for this problem .

 

 

 

2 the challenge:

 lack of awareness of the
application-virtual OS application platforms include virtual

 

virtual infrastructure software that can migrate instances mouth
turn from a single material, which often causes the interval on application
availability.

• if the distributed Resources are Scheduler (lessoning ) the
image moves into the different physical boxs, the application it will be unreachable  during migration, continue  and the client shop cart transactions.

 

 • New default images
easy, and then override the workflow model configurations as a result. It also
multiplies the mouth, August titles are lost, so the images are set wrong, and
adversely affected the availability.

 

 

 

 

Solution:

beige-August of IP management, management, application health, and
system availability, broksiingh links, and more.

 

 • Advance adding the
healths applications checks to monitor applications running on all the virtual
instrumentation. Beige-August to watch the status of the application and will
direct traffic to the right mouth as application availability and responding
time to fluctuate.

 

 • Communication paths to
another picture with maintaining connection application.

 • Prevents stretched mouth.
When all traffic is routed through big-August of, add pictures to collect and
convey the correct application of the ghorid before be available for traffic.

 

3 CHALLENGE:

Unforeseen additional
costs-cost virtual solution

 more than a physical problem and often
produces extra costs on the implementation of the default operating system,
there may be a need for new hardware and software licenses to resolve problems
related to availability, performance and management.

• As the Miss nude existing
infrastructure, requirements for application and storage networks grow.

 • New optional utilities management requires
increased staffing and training.

• Encoder create encrypted
virtual disk images that take a critical storage space.

 

Solution:
beige-August to have to load load balancing, SSL offload, caching, and
compression. F5 Acopia ARX ® ® virtual storage level. • With beige-August
because it was already in place, there is no need to buy new equipment to be
effective as in virtual space when managing and submitting the application
traffic.

• Investing in beige-August to
smart planning is for future growth because it will help to improve the virtual
infrastructure and expand with it.

• Virtual storage network arks
and expanding requirements of the mouth without any redesign. • Tiered storage
usage with arks to put the virtual disk images and critical data files on level
1 and storing less used images in the lower classes will prevent sprawl and
reduce backup costs.
