VIRTUALIZATION

VIRTUALIZATION

1. BENEFITS

   • Minimized or eliminated downtime.
   • Faster provisioning of applications and resources.
   • Simplified data center management.
   • Reduced capital and operating costs.
   • Greater business continuity and disaster recovery.

2. CHALLENGES

   • Resource Distribution
   • VM Sprawl
   • Backward Compatibility
   • Licensing Compliance
   • Security
   • Backup

3. In computing, virtualization or virtualisation is the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources

4. DRAWBACKS

   • High cost of implementation
   • Security risk
   • Availability
   • Scalability
   • Scalability

5. VIRTUALIZATION TYPES

   • Operating-system-level Virtualization
     • Type 1
       • A bare-metal hypervisor (Type 1) is a layer of software we install directly on top of a physical server and its underlying hardware.
     • Type 2
       • This type of hypervisor runs inside of an operating system of a physical host machine. This is why we call type 2 hypervisors – hosted hypervisors. As opposed to type 1 hypervisors that run directly on the hardware, hosted hypervisors have one software layer underneath.
