Using a combination of open-source platforms and in-house development, CloudSigma built a tiered-storage architecture that makes more efficient use of a new distributed system of solid-state drives SSDs and magnetic storage , Jenkins said. The result is less variability and higher performance, as the data is spread out over 50 or servers instead of being on one server, he said.

The challenges of supporting customers demanding big data analysis in the cloud don't end with storage. Cloud providers say it requires a more holistic approach to the network and overall cloud architecture.

That means acknowledging when big data analysis isn't suited for the cloud, said Jonathan King, vice president of cloud solutions at Savvis. But that's also where having a complementary set of hosting services comes in handy, he said. Big data analysis in the cloud also raises networking issues for service providers.

By having all of its partners and customers in one cloud, CloudSigma makes the most of its ecosystem strategy by running a Gigabit Ethernet network, "which means that you can fire terabytes of data around really, really quickly and at a very low cost," Jenkins said. Savvis, which CenturyLink acquired last year, is also considering the network implications of big data in the cloud. As SHI develops a big-data cloud service , likely to be released next year, the cloud provider is tapping its experience with high-performance computing HPC in the cloud through a partnership with HP to deliver IaaS to the Internet2 consortium.

In addition to improving storage performance, SHI's vCore architecture also "self-optimizes" networking and server performance as well, Fastert said. When you use [the vCore] model, it allows you to optimize subsections of that infrastructure very easily. It turned out that exact same form of optimization works exceptionally well for big data analytics.

That is permitted in their privacy policies, which users must agree to before they start using cloud services. Solutions to privacy include policy and legislation as well as end users' choices for how data is stored.

Program Information

These systems distinguish between authorized and unauthorized users and determine the amount of data that is accessible to each entity. Together, these form shared technology vulnerabilities. In a cloud provider platform being shared by different users there may be a possibility that information belonging to different customers resides on the same data server.

Additionally, Eugene Schultz , chief technology officer at Emagined Security, said that hackers are spending substantial time and effort looking for ways to penetrate the cloud. Because data from hundreds or thousands of companies can be stored on large cloud servers, hackers can theoretically gain control of huge stores of information through a single attack—a process he called "hyperjacking".

Some examples of this include the Dropbox security breach, and iCloud leak. By having these passwords, they are able to read private data as well as have this data be indexed by search engines making the information public. There is the problem of legal ownership of the data If a user stores some data in the cloud, can the cloud provider profit from it? Many Terms of Service agreements are silent on the question of ownership. This delivers great incentive to public cloud computing service providers to prioritize building and maintaining strong management of secure services. There is the risk that end users do not understand the issues involved when signing on to a cloud service persons sometimes don't read the many pages of the terms of service agreement, and just click "Accept" without reading.

This is important now that cloud computing is becoming popular and required for some services to work, for example for an intelligent personal assistant Apple's Siri or Google Now. Fundamentally, private cloud is seen as more secure with higher levels of control for the owner, however public cloud is seen to be more flexible and requires less time and money investment from the user.

Big Data and Cloud Computing: A Perfect Combination

According to Bruce Schneier , "The downside is that you will have limited customization options. Cloud computing is cheaper because of economics of scale , and—like any outsourced task—you tend to get what you get. A restaurant with a limited menu is cheaper than a personal chef who can cook anything you want.

Fewer options at a much cheaper price: it's a feature, not a bug. Cloud providers often decide on the management policies, which moderates what the cloud users are able to do with their deployment. Privacy and confidentiality are big concerns in some activities. For instance, sworn translators working under the stipulations of an NDA , might face problems regarding sensitive data that are not encrypted.

Cloud computing is beneficial to many enterprises; it lowers costs and allows them to focus on competence instead of on matters of IT and infrastructure. Nevertheless, cloud computing has proven to have some limitations and disadvantages, especially for smaller business operations, particularly regarding security and downtime.

Cloud Computing & Big Data

Technical outages are inevitable and occur sometimes when cloud service providers CSPs become overwhelmed in the process of serving their clients. This may result to temporary business suspension. Since this technology's systems rely on the internet, an individual cannot be able to access their applications, server or data from the cloud during an outage. Cloud computing is still a subject of research. The issue of carrying out investigations where the cloud storage devices cannot be physically accessed has generated a number of changes to the way that digital evidence is located and collected.

In some scenarios existing digital forensics tools can be employed to access cloud storage as networked drives although this is a slow process generating a large amount of internet traffic. An alternative approach is to deploy a tool that processes in the cloud itself.

For organizations using Office with an 'E5' subscription there is the option to use Microsoft's built-in ediscovery resources, although these do not provide all the functionality that is typically required for a forensic process. From Wikipedia, the free encyclopedia.

Moreover, it improves the security of the system.

Cloud Computing helps clients with a virtual environment, on which they can store data and perform multiple tasks. It can convert the clear text into an unreadable form. With the help of Cryptography, we can transfer the content safely by limiting the view of the document. Load Balancing is the distribution of the load over the servers so that the work can be easily done. Due to this, the workload demands can be distributed and managed.

There are several advantages of load balancing and they are-. The load balancing techniques are easy to implement and less expensive. Moreover, the problem of sudden outages is diminished. Cloud analytics can become an interesting topic for researchers, as it has evolved from the diffusion of data analytics and cloud computing technologies. The Cloud analytics is beneficial for small as well as large organizations.

It has been observed that there is tremendous growth in the cloud analytics market. Moreover, it can be delivered through various models such as. Analysis has a wide scope, as there are many segments to perform research. Scalability can reach much advancement if proper research is done on it. Many limits can be reached and tasks such as workload in infrastructure can be maintained.

It also has the ability to expand the existing infrastructure. The applications have rooms to scale up and down, which eliminates the lack of resources that hamper the performance. Cloud Computing platforms include different applications run by organizations. It is a very vast platform and we can do many types of research within it.

These are the vast topics for research and development as IaaS provides resources such as storage , virtual machines, and network to the users. The user further deploys and run software and applications.
