Q. Which platforms you will consider when it comes to cloud computing on a large scale?
Apache Hadoop is widely regarded as one of the finest option. It’s because this software platform can simply distribute and store data even if the same needs to be managed on a cluster. The reliability can also be assured when it comes to building the same from the commodity hardware. Another leading reason to consider the same is it always makes sure of data integrity, security, operations, governance as well as processing of same.
Q. Tell something about the deployment options you are familiar with which are common in the cloud technology?
It is not always necessary that a deployment model which is good for one organization also offer same pros for other organizations. Many internal factors related to organizations can impose a limit on them. The organizations which are large in size always prefer the private cloud while on the other hand, public cloud is a good option for the organizations with small size.
Q. Why would one use the API in the Cloud?
Generally, writing the fledged programs fully is something that waste a lot of time. API makes sure that need of same get eliminated up to a good extent. Application can be made to communicate with one another through the instructions provided by the API. Also, cloud can easily be linked to other systems outside the link.
Q. How private cloud and community cloud infrastructure are different from one another?
Private cloud is actually an option for the single organizations that can have multiple branches and units. Organizations are free to enable third-party businesses to operate their cloud. In other words, they can outsource their cloud operations to other organizations provided all the security policies defined by them are meet. Private cloud can be in a remote data center.
On the other side, community cloud infrastructure is considered by different businesses in a shared manner. All the tasks related to managing the same is the sole responsibility of their own. The community cloud infrastructure can also be in a remote data center that can be accessed easily.
Q. In the hierarchy of cloud, which layer is at the top?
Controller is always at the top and it manages the network, server, API, as well as storage of data.
Q. What do you understand with Paas, Iaas and Saas? How they can be put different from one another?
These are actually the different service models which are supported by the Oracle Fusion Cloud.
Paas in an approach in which the OS and hardware, both are provided by the third-party organizations and is managed by the Fusion. In Iaas, either hardware or the OS is provided by a third-party organization and in Saas, all the programs, as well as the applications are managed by a third party. These models make cloud computing different for different organizations. There are certain factors related to them which are also not same and this generally includes cost, as well as data security.
Q. Which option one should choose among “Cloud infrastructure exists in the data center of the organization offering cloud service” or it exists in their own organization and why?
Well, it largely depends on the factors such as budget/turnover of the organization. In addition to this, it depends on the overall quantity of data that an organization has to manage. Both have their own pros and cons.
Q. According to you, what is the best available strategy that one should consider to secure data before moving it in the cloud and why?
Probably the first step is to make sure that it is not possible for the others that the ones which are authorized to access data to be intercepted. Avoiding the data leaks is very important.
