Cloud computing provides on-demand access to shared computing resources like servers, storage, databases, networking, software, analytics and more over the Internet. It delivers these resources as standardized services in three main forms: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Cloud computing evolved from grid computing and combines technologies like virtualization, utility computing, and automatic computing. It offers advantages like lower costs, flexibility, scalability and mobility compared to traditional computing but also has disadvantages around internet dependence and vendor lock-in.

2. What is Cloud Computing ?

Cloud ????????????

4. Cloud + Computing

Cloud : Mass of infrasstructure.

Computing: computing part
* platform as a service
* infrastruce as a service

5. GRID COMPUTING
Emerging enables tchnology
 Natural evaluation of distributed system
and Internet.
 Middleware supporting network of
system to facilitate sharing
standandardization and openness.
 Infrastructure and application model
dealing with sharing of compute
cycles,data,storage and other resources.


6. Limitaions of grid
computing
Explosive growth in application biomedical
informatics, space exploration, business
analytics
 Expenotial growth in compute capabilities:
multi core,storage,bandwidth virtual machine
 Very short cycle of obscenest in technology:
windows 7-window8, java versions; c-C#;
python


7. Answer is cloud computing
Cloud computing environment can
provide one or more of software these
requirements for a cost.
 Pay as you go model of business.
 When using a public cloud the model is
similar to renting the property than
owning one.
 An organization may also maintain a
private cloud and use both


8. What is cloud computing
Provide a variety of computing resources,
from servers and storage to enterprise
applications such as email, security,
backups all deliver over the internet.
It deliver a hosting environment that is
immediate,flexiable, scalable,secure,and
available while saving corporation
money, time, resources

9. Cloud computing is
combination of
Grid,
virtulization,
utility,
automatic computing.

11. eg
Hotmail – first in application software
Amazon- first in infrastructure as a
storage devices ,data storage area
Google-gdrive,microsoft- office 365

15. Cloud component
Client
 Data center(collection of servers
where the application to which you
subscribe is hosted )
 Internet

16. Virtual Machines
VM technology allows multiple virtual machines to
run on a single physical machine

17. Advantages of cloud
computing
Lower computer cost
 Improved performance
 Reduce software cost
 Instance software update
 Improved document compatibility
 Unlimited data storage
 Data reliability
 Device independence


18. Disadvantages of cloud
computing
Constant internet connection
 Does not work well with low-speed
connections
 Features might be limited


Each cloud systems uses different
protocols and different APIs
