Cloud computing and its security issues — A review

Abstract

Cloud Computing is one of the popular techniques in distributed computing due to its ability to minimize the cost of computing when scalability and flexibility of computer process get increased. Cloud Computing provides shared resources and services via internet. Services are delivered through data center. Cloud Computing allows an interesting business proposal for IT industries to provide IT services without any extra investment. Client is able to perform heavy computer processes with low capable device (like mobile) which has resource to run the web browser. But cloud computing is crowded with many security related issues. When client saves his data to the company's cloud, there may be chance of data breaching. So the purpose of this paper is to search out various issues in cloud computing where all computing is done on the server side and both data & tasks are stored on the data centers.

A Review on Software-Defined Networking Enabled Iot Cloud Computing

“…Cloud computing has come up as a typically acknowledged registering worldview worked around centre ideas [19], as an example, elimination of forthright venture, the diminishment of operational prices, on-request process resources, versatile scaling, and putting in compensation for every utilization arrange action for information innovation and computation administrations [20]. Cloud computing has given economy to ability through financially savvy and versatile IT profit worldview.…”

“…Cloud computing has given economy to ability through financially savvy and versatile IT profit worldview. The specialist additionally outfits its benefits, the pay-as-you-utilize estimating model for example, and flexibility to reinforce their nature of administration and to minimize their price [20]. In cloud condition, skill and flexibility will be accomplished by more decreasing or increasing virtualized foundation assets, e.g.…”

MA Assisted and Restrained Sink Mobility based Economical Data Processing in WSNs: MARS

“…Overview This paper proposes a method i.e. mobile sink energy efficient data gathering for WSNs [20][21][22][23]. This technique designs a tree structure network and perform data gathering [24][25][26][27] with mobile sink, in detail it discussed below.…”

“…[14][15][16][17][18] Presented scheme introduces controlled mobility of sink and compare it with random mobility of sink for the same network topology. [19][20] The proposed model is Mobile Agent (MA) assisted i.e. For the purpose of data processing, MA travel over the network and generate tree structure path which would be base for every parent node to perform data gathering.…”

Survey on Big Data Tools and Techniques

“… Processing and storage issues: Since Big data involves large amount of data ,this processing of such large data takes more time ,more over it also require proper storage for storing huge data [4],uploading this large data in cloud [13] [14] [15] does not alone solve the problem ,thus right indexes should be build up in the beginning itself while the data is being collected and stored, this will make a good practice and the time for processing is reduced to a great extent.  Representation of data: Data in Big data is of heterogeneous in nature .The representation of data should be in such a manner that it reflects the appropriate data structure, class type, this will ensure better operations on various data sets .Thus it imposes a big challenge on Big data.…”
