WHAT IS GRID COMPUTING ..?



GRID COMPUTING «

Grid computing is a form of distributed computing

whereby resources of many computers in a network

is used at the same time, to solve a single problem.

Grid systems are designed for collaborative sharingof resources.



MECHANISM OF GRID COMPUTING «

When a large task need to execute.

First it understand the flow of the program & segregate.

Among those segregated modules ,it identify the moduleswhich can executed independently.

Those independently executable task are assigned to

different machine( for achieving high computational power).

After complete execution of every module, the original

machine collects all the results of every terminal ,group

them and produce as final output.

APPLICATIONS «It se in eat er f r ecasting.

Intelligence)

Using this application, the end- ser can donate their

nused pr ocessing power to the pr oject(li e scientific

r esear ch or ganizations).



Are you facing a problem in Purchasing and

installing the s/w¶s for every new computer in an

organization«?

Single application can solve u¶r problem«.i.e. cloud computing«

What is

Cloud Computing...?



CLOUD COMPUTING«.



LIVE EXAMPLEu



ACHRONYM OF CLOUD ACCORDING TO AT&T«







LAYERS..:



- Software as a service.End user can use available s/w¶s in cloud, but the end

user can not perform changes on s/w.eg: Mozy : It helps people to backup their data.

cloud consumers can use this s/w without buying or

coding.

- Platform as a service.Developers use this layer to build , test & host the

applications.

eg:-Windows Azzure.

-Infrastructure as a service. No need to purchase or manage physical datacenter

equipments(servers, storage , networking etc..)



CLOUD TYP «

Public cloud

Private cloud

Hybrid Cloud







Cloud Computing Services:





ISSUES TO CONSIDER«

THRESHOLD POLICY :- It quickly allot & relieve

the resources as per the client request

INTEROPERABILITY ISSUE:-Migration of data is

possible from one cloud provider to another

cloud provider.

HIDDEN COST



SECURITY IN CLOUD COMPUTING«.



Encoding technique :



1. Generate random symmetric key: R

2. Encrypt data

3. Calculate hash of encrypted data: H

4. Append (H XOR R) to the encrypted data

Encoding steps:



Decoding technique:





ADVANTAGES:

1. Consumer can easily maintain the data on cloud.

2. Cloud providers can easily increase their profits by

reprovision of resources to the customers.

3. Using this employees can work from home.

4. Pay for what you use.

5. Accessing the data is always possible(not only in the office)

6. The cloud is scalable.

7. Environment Friendly(Green computing)



DISADVANTAGES:

1. Additional cost of data transfer fees.

2. It poses a serious security uestion, as your data is

held in the hands of third parties and you have no other

choice but to trust them that they will keep your things

safe and private.



GRID VS CLOUD«



Conclusion«

Grid computing provides the mean to share and unify

heterogeneous computing resources.

It is the starting point of the cloud computing.

Cloud computing essentially represents the increasing trendtowards the external deployment of IT resources, such as

computational power, storage or business applications and obtain

them as service.
