2. Introduction
A service model in which data is
maintained, managed, backed
up remotely and made available to users
over a network (typically the Internet)
The physical storage spans multiple
servers (and often locations), and the
physical environment is typically owned
and managed by a hosting company .
These service may be accessed through
a co-located cloud computer service,
a web service application programming
interface (API) and other application
that utilize API .
Examples:OneDrive, Dropbox, Google Drive
3. History
1. Joseph Carl Robnett Licklider had a vision–one of
a global connection that provided all people with an
internet connection access to an overarching
storage system
2. In 1960s the computer scientist with his work
on ARPANET succeed in introducing first viable way to
send data through packets
3. He has been called "computing’s Jonny Appleseed",
for planting the seeds of computing in the digital age
4. 4. In 1892 IBM introduced Ethernet that
allowed the incredibly fast yet inexpensive
online storage to begin
5. AT&T launched PersonaLink Services – an
online platform for personal and business
communication and entrepreneurship
storage
6. In 2006 Amazon Web services introduced
their cloud storage service AWS S3 and
has gained widespread recognition and
adoption as the storage supplier to
popular services such as Smugmug,
Dropbox, Synaptop and Pinterest .
5. Characteristics
Made up of many distributed resources, but still acts
as one, either in a federated or a cooperative storage
cloud architecture
Highly fault tolerant through redundancy and
distribution of data
Highly durable through the creation of versioned
copies
Typically eventually consistent with regard to data
replicas
6. Private
❖ Single tenant
implementation
❖ Owned and
operated by IT
organization
❖ Define your own
management
policies
❖ Self-service
❖ Combination for
private & one or
more public clouds
❖ Allows IT
organizations to
become brokers of
services
Public
❖ Multi-tenant
implementation
❖ Owned and
operated by service
provider
❖ Bound by multi-
tenant data
management
policies
❖ Similar self service as
private
Hybrid
