 Overview

 Cloud Approaches

 Real-World Case Study

2110414 - Large Scale Computing Systems 3 Overview

2110414 - Large Scale Computing Systems What is Cloud Computing?

 Various definitions  Wikipedia  Web-based processing, whereby shared resources, software, and information are provided to computers and other devices (such as smartphones) on demand over the Internet  Gartner  a style of computing in which massively scalable IT-related capabilities are provided 'as a service' using Internet technologies to multiple external customers

2110414 - Large Scale Computing Systems Common Understanding about Cloud Computing 5

 Web-enabled services (software/platform/infrastructure)

 Remote datacenter

 Shared resources via virtualization

 Outsource maintenance tasks to the hosting organizations

2110414 - Large Scale Computing Systems (Good Luck) Defining Cloud Computing

 Software-as-a-Service

 “My customer resource management (CRM) system is out on the Internet!”

 Grids vs. Clouds

 Shared Virtual Resources

 Batch Jobs vs. Online Applications

 Different Approaches to State Management

 Network Diagrams

 A service is “on a cloud somewhere”

 Virtualization Platforms & APIs

 Hardware can be manipulated with software
