Introduction: Evolution of modern IT infrastructure –1950s: Stand-alone mainframes –1960s: Mainframe and dumb terminals –1970s: Stand-alone personal computers –1980s: Local area networks (client/server computing) –1990s: Enterprise computing –Currently: Cloud computing and mobile computing

What is Cloud Computing? Definition Characteristics –Provides on-demand self-service –Encompasses grid computing to provide high performance computing –Encompasses utility computing to provide resources as needed –Utilizes broad network access –Pools computing resources –Often occurs on virtualized servers

Different Types of Cloud Computing Public clouds Private clouds Hybrid clouds Vertical Clouds

Cloud Computing Services Three service models of cloud computing –Infrastructure-as-a-Service (IaaS) –Platform-as-a-Service (PaaS) –Software-as-a-Service (SaaS)

Cloud Computing Benefits Making individuals more productive Facilitating collaboration Mining insights from data Reduce costs Expand scope of business operations Respond quickly to market changes Customize products and services

Concerns and Risks with Cloud Computing Legacy IT systems Cost Reliability Privacy Security The regulatory and legal environment

Web Services and Service-Oriented Architecture Web Services Service Oriented Architecture
