  CLOUD COMPUTING

 

 




Cloud computing is the act of running workloads within clouds—which are IT environments that abstract, pool, and share scalable resources across a network. Neither cloud computing nor clouds are technologies unto themselves.


  • Cloud computing is an act—the function of running a workload in a cloud.
  • Clouds are environments—places where applications run.
  • Technologies are things—software and hardware used to build and use clouds.

 

 

Types of Virtualization:

  • Application Virtualization
  • Network Virtualization
  • Desktop Virtualization
  • Storage Virtualization
  • Server Virtualization
  • Data Virtualization

 

Case Studies

   

Data Virtualization



Storage area networks (SANs) have become commonplace in the modern data center and are especially valuable for virtual systems. However, it is critical to plan and budget for all the technology needed to properly deploy and manage a SAN. Planning ahead is also essential for identifying the potential costs that could surface beyond the initial SAN deployment and is key to benefits of virtualization. This case study shows what happened when an IT solution provider supported a data virtualization project for an architectural firm that did not budget for licensing costs and SAN management tools

 

 

Server Virtualization

 

Virtualization isn't just for large data centers supporting enterprise businesses. Even smaller organizations can use virtualization technologies to improve performance, as evidenced by this case study of a New York healthcare provider. The company's director of IT was frustrated by frequent downtime caused by aging servers and had to maneuver his way through long-expired warranties and self-maintenance, and eventually turned to server virtualization. This case study illustrates why a well-built virtual infrastructure is often more reliable than its physical equivalent. It also demonstrates the other benefits of virtualization that can be realized, including high availability and increased reliability.

 

Storage Virtualization

 

Virtualization for Flash Storage

   Virtualizing for flash storage allows you to balance performance with data storage features with the organization workload needs. A flash sysyem provides cost efficient virtualized storage for oraganizations of all sizes and enterprise class data services.
