Progress to Uprising

• 1960 – Virtualized Memory Systems

• 1970 – Virtualized OS (IBM)

• 1980 – ??? (low-cost desktop )

• 1990 - ??? (low-cost desktop )

• 2000 till today – Virtualization has become a buzz word

Need of an hour:

• Agile Business Requirements• Increased Total Cost of Ownership• Resource sprawl • Low Resource utilization • Complex server-storage migration • Inefficient Resource deployment • High-availability complexity • Disaster-recovery complexity • Need for Green IT• Automating Processes• Policy Driven Management
