Public Cloud And Private Cloud

Enterprises around the world would be wise to heed 50 Cent’s mantra ”Get Rich or Die Tryin’” when considering the implications of not “getting” to the public cloud. We at Cocolevio, an implementation partner of Mooor Insights & Strategy, estimate that over 50% of IT spend will be going to public cloud vendors such as Amazon Web Services or SaaS vendors like Salesforce.com Inc. by 2019. This means there is around a $140B opportunity in this space. The cost savings, reduction in capital spending, speed to market, flexibility and global access derived from public cloud mean those enterprises that effectively use the public cloud are better positioned to “Get Rich” than their competitors who have higher cost structures and less nimble IT platforms. This trend is only set to continue as the business case for moving to public cloud only becomes more compelling, with the traditional arguments against public cloud around security and lack of control diminishing. Vendor lock-in will continue to be a concern but we see many companies willing to sacrifice a bit of lock-in for the many, many benefits of public cloud.

Cloud computing is a fast growing information technology trend that many companies including Google, Microsoft, and IBM are currently looking to get a stake in as demand for the service grows. Cloud computing is the concept of allowing both individuals and businesses to store data and applications on remote servers (owned and operated by a third party company), rather than on their own hard drives and data centers. The service boasts the ability to securely access data and applications from just about any device with an internet connection, allowing for such services as streaming music from a personal collection from multiple devices, and even to business

The other main sensitive issue while in the cloud is that of security issues before assume this technology you have to know that you will be surrendering company’s important information to a third party cloud service provider (Singh and Dhawan et al., 2013, pp. 387--392). This could put you safety of your company in dangerous which could you facing many troubles so the device is that you should choose the most reliable service provider who will safe the data (Leavitt, 2009).

Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any

Cloud computing security or, more simply, cloud security is an evolving sub-domain of computer security, network security, and, more broadly, information security. It refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing.

Cloud computing is provided by an outside organization; it takes the place of an existing system, usually an internal network, and moves it to a web based service where all information in the company will be processed and stored. Internal IT infrastructures can be costly due to maintenance and personnel. Cloud computing reduces costs by removing the need for an internal system and the people to run it.

Business owners use three types of cloud service, public, private, and hybrid these clouds store their data and provide them with services. The benefits of these clouds are endless, additionally, they saves businesses time and money, promoting innovation, enhancing productivity, and improving communication while cloud hosting accelerate information sharing, like email, application hosting, web-based phone, and data storage (Griffith, 2013).

Public Cloud - The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

With public clouds, when a customer chooses to house their information in this way they lose the physical access to their servers hosting that data. The cloud provider itself has physical access, and the vulnerability that this exposes are insider attacks. An insider attack would be when an employee of the cloud provider accesses data that they should not. Cloud providers need to ensure that their hiring policies involve stringent background checks and that all data centers have monitoring to ensure that suspicious activity is caught early.

Private cloud is an infrastructure operated solely for a single organization, whether managed internally or by a third-party, and can be hosted either internally or externally.

According to Lawrence Shawa, "a number of organizations I have spoken to have expressed concern about how secure their data is that is hosted in the cloud. There is sense of control that is taken from them making the organizations feel vulnerable" (Collection 2:1) Companies naturally feel a strong sense of obligation to protect their customers. Additionally, they may lose business if they have a reputation for compromising customer security.

Furthermore, different deployment models exist, we are going to focus only on the two different poles, the private cloud and the public cloud. The former means that the cloud infrastructure is owned and operated by a single and usually the same organization, while the latter stands for a public infrastructure where basically everyone can use it under different conditions. And this is the “cloud” we will be referring to in this essay.

Another issue with cloud computing is how protected is your data and what happens to your data if the company you subscribe to no either goes out of business or if you no longer subscribe to them. Additionally, some uses do not like becoming dependent upon cloud computing, prescribing to the “don’t put all of your eggs in one basket”

To provide a secure cloud computing solution, an organization needs to decide on which type of cloud to be implemented.

Everyone has an opinion on what is cloud computing. It can be the ability to rent a server or a thousand servers. It can be the ability to rent a virtual server, load software on it, turn it on and off at will. It can be storing and securing large amounts of data that is accessible only by authorized applications and users.
