Cloud Computing - An Overview

This presentation provides an overview of Cloud Computing, its services, benefits, challenges, and types. It covers topics like the Cloud Computing model, services provided by Cloud, features offered by Cloud Computing, components of Cloud Computing, and advantages of Cloud Computing. It also discusses the challenges faced by Cloud Computing like security, legal issues, and limited control. References are also provided for further reading.

Cloud Computing
Software Engineering

Cloud Computing
• Provides services based on internet
• Supports services with the help of web
based application and tool
• All the resources are stored with the cloud
server

Cloud Computing
• Allows the user to access data at anytime
• Cloud offers pay as you go model
• high-capacity networks are available

Cloud Computing
• Low-cost computers with better storage devices are offered with
cloud
• Widespread adoption of hardware virtualization,
• Provides service-oriented architecture

Cloud Computing model

Services provided by cloud
• Service provider: responsible for developing services.
• Service consumer: has the ability to build an application
• Service broker: this helps to know about the services available

Features offered by Cloud
Computing
• Allows better resource pooling and elasticity
• Cost effective solutions are provided by Cloud
• On demand services are provided by cloud computing
• Cloud computing offers self service

Components of cloud computing
• The three components
associated with the cloud
computing includes:
• Client computers
• Distributed servers
• Data centers

Services offered by Cloud
• Software as a Service
(SaaS): this
architecture offers
software as a service
and allows the user to
develop application
with the help of
software.

Services offered by Cloud
• Platform as a Service (PaaS): PaaS allows the users to develop a
software by using patform.
• Infrastructure as a Service ( IaaS): there is no need to buy the
software and can move to perform functions.

Different types of Cloud computing
• Public Cloud: allows the public to access
the service and can pay only for the
services consumed by them.
• Private cloud: the computing services are
provided towards a certain organizations
people. These structure provides high
security.
• Hybrid cloud: this cloud is the
combination of both private and public
cloud. The data are shared among the
clouds within the hybrid cloud.

Benefits of cloud computing
• The main benefits offered by cloud computing includes:
• The amount of cost needed to buy hardware's and software gets
reduced.
• Security features get enhanced
• Easy accessibility at any time
• Offers flexibility
• Scalability

Benefits of cloud computing
• High Speed
• Back-up and restore data
• Manageability
• Sporadic Batch processing Strategic edge
• Offers business continuity plan

Advantages of Cloud computing

Challenges
• It is difficult to provide security in multitenant environment
• Sometimes it becomes difficult to rely completely on cloud server
• Organization needs to work with proper service provider for gaining
effective service
• Legal issues arises when an unauthorized person access the data
uploaded within the cloud

Challenges
• Cloud server are vulnerable towards attacks
• Dependent on quality of internet
• Limited control is provided towards the users
