virtualization
Help organizations reduce IT costs while increasing operational efficiency and flexibility by building software or virtualized versions of applications, servers, storage, and networks.
Partition
It allows multiple operating systems to run concurrently on a single physical server, and the ability to allocate computing resources on demand.
Isolate
Isolation of failure and security at the hardware level, while providing advanced resource management to maintain performance.
Encapsulation
The ability to archive the entire virtual machine state into a single file makes it easy to move and copy virtual machines.
Hardware independence
Virtual machines can be deployed or migrated to different physical servers, regardless of the underlying hardware.
Advantages of virtualization technology
Significantly reduce initial investment and operating costs
Reduced service interruptions and near zero downtime
Simplify data center operations management
Implement a fully software-defined data center architecture
Enhanced business continuity planning to ensure disaster recovery
Enhance the operational efficiency, productivity, flexibility and resilience of the IT department
Rapidly deploy applications and resources for faster service delivery
Optimize resource utilization and improve the energy efficiency of infrastructure through dynamic resource allocation
Types of virtualization
Server virtualization
Server virtualization technology allows multiple operating systems to run simultaneously on a single physical server, improving resource efficiency in the form of virtual machines. Its advantages are:
· Improved the efficiency of IT operations
· Reduced operating costs
· Accelerated deployment of workloads
· Enhanced application performance
· Improved server availability
· The number of servers is avoided
Network virtualization
Network virtualization enables applications to run seamlessly in a virtual environment and enjoy the same performance as a physical network, while providing operational convenience and hardware independence by creating virtual network replicas. Network virtualization provides logical network devices and services, such as logical ports, switches, routers, firewalls, load balancers, and VPNS.
Desktop virtualization
With desktop virtualization, IT is able to offer the desktop as a managed service, quickly adapt to changing workplace needs and respond quickly to emerging opportunities. In addition, virtualized desktops and applications can be easily and quickly delivered to branch employees, outsourced and offshore employees, and mobile employees using ipads and Android tablets.
Virtualization and cloud computing
Virtualization and cloud computing are closely related, but they serve different purposes. Virtualization is a software technology that abstracts computing resources from physical hardware, while cloud computing is a service model that provides on-demand shared resources over the Internet. Enterprises can first increase efficiency through virtualization, and then further leverage cloud computing to increase flexibility and self-service capabilities.
