This literature survey is about cloud computing that emphasizes its advantages and disadvantages, its security, types of cloud services and strategies on implementing cloud computing.
2.1) Advantages and disadvantages of cloud computing
Cloud computing can be considered as one beneficial tool. However, no matter how perfect every technology is, it always comes with both advantages and disadvantages.
2.1.1) Advantages of cloud computing
These are some advantages of cloud computing:
2.1.1.1) COST
With cloud computing, (Romero, 2012) mentioned that it helps to ieither increase or decrease the hardware or software usage; but importantly, it helps reducing the capital expenses (L.Grossman, 2009). Miller (2009) suggest that instead of investing in …show more content…

Aljabre (2012) assumed that to use cloud computing, a constant strong and fast speed Internet connection is needed, without it, anything in the cloud could not be accessed. This can be considered as one of the important requirement in adopting cloud computing.
Depending on web-based applications, (Miller, 2009) if the users are unable to continue their work due to no access to the Internet or the Internet speed is low; they will think that using this cloud computing is problematic as they carelessly did not save it in their smart devices. In addition, even if the connection is strong and fast, any web-based applications can sometimes be slower to access depending on the data layout and sizes.
2.1.2.2) FEATURES
Cloud computing web-based has been said more advanced but many web-based applications are not fully featured as the desktop applications, hence, it will restrict the users to use any types, structures, or layout even though the basics are similar (Miller, 2009). Furthermore, it is cited by (Aljabre, 2012) that cloud computing seems to have limited features in application, which can be compared on doing presentation in Google docs and Microsoft Power …show more content…

Moreover, it is also possible that a conflict between personal protection and legal system data to happen, at any place in the cloud provider (Fortinova, 2013).
2.2) Security of cloud computing
Generally, when the security word comes to be the topic it means, the safety of institutions or organizations against the cyber criminal and in simpler terms, free from any vulnerabilities and risks. It has been said that cloud computing is one recent innovation that opens a lot of opportunities for the people up to their conveniences, nonetheless, it comes with a lot of issues in the computer world; the fundamental question is “how secure is cloud computing?” and the answer can be one incredible discussion (Davenport, 2012).

In any institution and organization, having web-based applications run in the network server, it will always has the potential of being attack. This is the most important for any institution and organization to worry about: the data protection, as storing the data in the cloud will pose some risks of exposing the private and confidential data to the other users or hijackers to be exact. (Jamil & Zaki, 2011). This data protection requires trust to be put into the vendors, to make sure if is safe with the Service Level Agreements (SLAs) (Tout, Sverdlik, & Lawver,

Not only will these innovations improve network strength, but possibly the speeds at which a client can access information from an application server. This has the potential to make cloud computing even more prevalent than it already is today because it would become easier to keep up with mass traffic to the servers. Large server banks would be able to be downsized slightly compared to their current sizes. The computer science techniques used in created Marple show that it is possible to even make an old process useful in modern applications. The hardware of Marple is also programmable making it extremely useful for any network engineers because they will be able to write custom software for Marple-based

2.7 Observations from GMPCS Model Based on the above model, several observations can be made as follows. Observation_1: According to an interoperability feature between CSPs, a storage service will be hosted over a pool of resources that are in different geographical locations. Furthermore, different technologies, protocols, and security strategies are applied by each CSP within its datacentres to facilitate managing an environment to protect both resources and data. The technologies and strategies, therefore, might be disparate in terms of efficiency, and the type of storage network or storage system might be varied as well.

Hi, Todd, how do you do? I hope my message finds you well. Regarding your request, we - GI_SSC_OM_S1 and GI_SSC_MFGPTS_S1 squads - only will be able to answer the Security and Risk questionnaire after we access the environment of our clients, that only will occur when Chris Maurer validates the data we sent to him from application owners and he informs us how we must to procede to start the access procedures without violate the export regulations rules from IBM. As we only receive part of the list that we sent to application owners (AO) yet, we have two situations right now: some data still under verification by AO and others under validation of Chris, as the graph bellow: Our PO and SLL are aware of this situation.

KELSER – ‘Technology forward’, provides a cloud solution for disaster recovery and targets especially small and medium business (SMB’s) which can provide a speedy recovery with lesser hardware dependency. The main advantage of using Kelser products is that it provides scalability for its DR services and can be purchased on ‘a need’ basis. The biggest drawback is that, it does not address all the business units of an organization and hence the DR process cannot be address at an organizational level which leads to lack of ownership in dealing with disaster recovery (KELSER, 2016).
