Evolution of Computing Power

Early Sharing Concepts

• In the mid-1950s to 1965, John McCarthy proposed sharing computing power among users due to high costs associated with computers at that time.

• IBM introduced time-sharing systems allowing multiple users to share a single computer's resources efficiently.

Virtualization Emergence

• Virtualization technology began gaining traction around 1999 with VMware software enabling users to create multiple virtual machines on a single physical machine.

Modern Cloud Services Development

Introduction of Cloud Storage Solutions

• In 2006, Amazon launched S3 (Simple Storage Service), marking a shift towards businesses renting computing power rather than purchasing physical hardware.

Advancements in Container Technology

• By 2010, container technology emerged as a solution addressing limitations of traditional virtualization by offering lightweight and efficient resource management.

• OpenStack was introduced as open-source software allowing companies to build their own clouds while managing servers and storage effectively.

Containerization Concept

Benefits of Containers

• Containers provide lightweight application versions that are quick to deploy and easy to transfer across different environments without heavy resource demands.

Understanding Virtualization and Cloud Computing

Introduction to Virtualization
