Cloud Computing: Architecture, Models, Services, and Implications

Desklib provides past papers and solved assignments for students. This report explores cloud computing.

Cloud Computing

What is cloud computing?
• Cloud computing can be explained as
consumption and delivery system for
the Services based on IT and internet.
• It comprises of dynamically Accessible
and frequently virtualized properties as
service.
• There are many new things associated
with cloud computing such as business
model, access model, acquisition
model, and technical model

Architecture of cloud computing
• The cloud architecture distinguishes
the components and the relations
among them.
• There are several components of
cloud computing such as cloud
resources, middleware, on premise
resources, and services related to
software.
• It mainly aim to provide the high
bandwidth to the users.

Models of cloud computing
There are mainly three models of
cloud which are:
• Public cloud: sharable to many
organizations such as Google, Sales
force etc.
• Private cloud: does not sharable
with other organizations such as
oracle, IBM, 3TERA ETC.
• Hybrid cloud: arrangement of
public and private cloud.

Cloud computing services
• SaaS: With the use of SaaS, the
providers of cloud manage and host the
software-based application and handle
any kinds of issues and maintenance.
• PaaS: PaaS defines the services that
supply on the environment based on
the on-demand services.
• IaaS: Company can rent the servers
based on the IT infrastructures, storage,
operating systems, and networks.

Advantages and disadvantages
Advantages
• Low cost on software.
• Increase the safety among
data
• Enhance performance
• Instant updates in software
• Less issue regarding
maintenance
Disadvantages
• Require internet connection
all the time when using it
• Sometime slow
• During low speed
connections, does not work
well
• Less features
