Spring 2010 ©15-319 Introduction to Cloud Computing
Utility Computing
Water, gas, and electricity are provided to every home and business
as commodity services
You get connected to the utility companies’
“public”
infrastructure
You get these utility services on‐demand
And you pay‐as‐you use
Utility Computing
is doing same for computing resources
(processing power, bandwidth, data storage, and enterprise
software services)
Thought of by 1960s but re‐surfaced late 90s
“If computers of the kind I have advocated become the computers of
the future, then computing may someday be organized as a public
utility just as the telephone system is a public utility... The computer
utility could become the basis of a new and important industry.„—John McCarthy,
MIT Centennial in 1961

Using distributed systems to solve large problems.
Distributed System:
multiple autonomous computers connected
through a communication network
The system has a distributed memory
where each processor has
its private memory.
Information exchanged using communication models, ex:

Cluster Computing:
Characteristics:–
tightly coupled computers–
single system image–
Centralized Job management & scheduling system
Better performance and availability and more cost‐
effectiveness over single computer with same capabilities
Since 1987
Grid Computing:
According to Gartner, "a grid is a collection of resources
owned by multiple organizations that is coordinated to
allow them to solve a common problem."
Characteristics:–
loosely coupled–
no Single System Image –
distributed Job Management & scheduling
Originated early 1990s
