Virtualisation

Virtualisation

1. Drawbacks

   • It creates an availability issue
   • time consiming
   • It creates a scalability issue
   • It can have a high cost of implementation
   • It creates a security risk

2. definition

   • Creating a virtual vision of something
   • hypervisor
   • vmware

3. Advantages

   • increase IT agility
   • flexibility
   • Stability
   • Faster provisioning of applications and resources.
   • Reduced capital and operating costs.

4. Challenges

   • Lack of application awareness— OS virtualization doesn’t virtualize the application
   • Additional, unanticipated costs—the virtual solution costs more than the physical problem
   • Unused virtualization features—the network limits implementation
   • Depleted resources—performance and availability suffer
   • Overrun storage network—growth exceeds planning

5. types

   • OS Virtualization—aka Virtual Machines.
   • Application Virtualization.
   • Application-Server Virtualization.
   • Administrative Virtualization.
   • Application Virtualization.
   • Hardware Virtualization.
   • Network Virtualization.

6. cloud virtualisation

   • Protection From System Failures
   • Hassle-Free Data Transfers
   • Firewall and Security
   • Smoother IT Operations
   • Cost-Effective Strategy
