Centralised Computing in the 1950s
Back then, big and expensive mainframes needed experts to run them. These machines focussed all the data work in one place. This helped schools, businesses, and more. It also sparked new ideas, like sharing the computer’s time among users.
Time-Sharing Concepts
Time-sharing was a big change. It let lots of people use the same computer at the same time. This made computers more useful for everyone and helped start modern computing ideas. With shared access, companies got more value from their tech. This was the beginning of cloud computing that provides flexible services for all kinds of work today75.
The Birth of Virtualisation
Virtualisation is a big step in cloud computing history. It started in the early 2000s. A single physical server could then run multiple virtual machines. This opened up new ways for efficiency and flexibility8. Today, it’s a key part of modern IT setups.
Understanding Virtual Machines
Virtual machines are stand-alone areas. They let different systems and applications run together on one piece of hardware. This makes managing resources easier and lets companies use their hardware fully8. Giants like Amazon Web Services, Microsoft Azure, and Google Cloud offer virtual machines. They use a pay-as-you-go system, saving money and increasing flexibility.
Cost Efficiency and Resource Utilisation
Virtualisation helps save money and use resources better in many industries. It cuts down on the need for physical hardware. Plus, companies can grow their operations easily98. Recent studies confirm that virtualisation reduces costs for both infrastructure and management. This shows the benefits of such innovative tech.
