The fact is there are certain levels of security that organizations must pay attention to. Oracle Fusion Cloud allows identity management which is a good security measure. It makes sure that the applications, hardware, as well as services are only used by those who are authorized for the same. Another measure is access control. It makes sure that users always remain in a position to control the entire access of the cloud if they are authorized. In addition to this, authentication and authorization are the other methods that users can deploy to keep up the pace simply.
Q6. Suppose you need to transfer the maximum amount of data very quickly in or out from the cloud what would you do?
Using “Performance Cloud” is a good option. It is actually used by a lot of professionals for getting the outcomes that are advanced and need fast data transmission.
Q7. On which servicing model Oracle Fusion cloud technology is based?
It is based on Saas which is also one of its biggest benefits
Q8. 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 the 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.
Q9. According to you, what is the best available strategy that one should consider to secure data before moving it to 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 data leaks is very important. There are several options for securing keys that can be opted. Also, it is necessary to check that the data is not infected by any malware and virus.
Q10. What do you understand from the term utility computing?
It is actually regarded as one of the cost-saving strategies by many businesses in need of cloud services. In Oracle Fusion, it is possible for the users to pay for the service they are taking on a per-use basis. All the organizations that consider the growth and scale model can benefit from this. The best part services, as well as the applications, can simply be implemented as per the needs.
Q11. Tell me something about the Open source cloud database platform you are familiar with?
The fact is Open source is something that enables the users to manage the cloud exactly in the way they want. Because scalability, reliability, efficiency, as well as speed, matters a lot, a document-oriented approach is very important and offers high storage abilities. Some open-source approaches which are common are CouchDB, MongoDB as well as LucidDB.
Q12. What exactly do you mean by Eucalyptus?
It is actually a combination of the following terms
It is actually a third-party software that can be used for the implementation of the different clusters in the cloud. Basically, it can be considered to divide a cloud into a hybrid, community, private as well as public domain. The entire data center can easily be transformed into a private cloud in case the need for the same is realized.
Q13. Which platforms will you consider when it comes to cloud computing on a large scale?
Apache Hadoop is widely regarded as one of the finest options. 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 the processing of the same.
Q14. Name two categories in which the data centers can be put in the Cloud environment?
- Low-Density Data Centers
- Containerized Data Centers.
Q15. Is it possible to reconcile the data from output form to input form?
In Oracle Fusion Cloud, it is possible and can generally be done with the help of an approach known as Input Validation.
Q16. Name one optimization strategy that is useful during a data disaster approach?
Oracle Fusion allows the concept of using a three-data approach which makes sure of data backup. Using the same is always a good option for the organizations as this can simply enable them to keep up the pace with data all the time.
Q17. Why would one use the API in the Cloud?
Generally, writing fledged programs fully is something that wastes a lot of time. API makes sure that the need for the same gets eliminated up to a good extent. The application can be made to communicate with one another through the instructions provided by the API. Also, the cloud can easily be linked to other systems outside the link.
Q18. How secure is data on the cloud?
Well, organizations need not worry about the same and this is because the cloud is a safe approach. It comes with multiple benefits and users need not worry about security. This is because users are allowed to impose various security restrictions on their data such as log in with a user name and a password, data encryption, and so on. However, there are certain factors that organizations must pay attention to before they consider any cloud service.
Q19. What is the lowest level of cloud architecture in Oracle Fusion and what does it provide?
The lowest level is Node Controller and it is responsible for controlling the activities of Virtual Machines. It can also be employed for termination, execution, and managing the same.
Q20. Name the approach that makes sure that the data is processed in a recommended manner within an application in the cloud?
This approach is Process Controlling
Q21. Tell me any two benefits of Cloud technology that you think are the best it can offer to organizations?
For organizations, it is possible to access the applications/software without installing them in the system. In addition to this, for large-scale applications, the cost related to support and maintenance can be eliminated up to a good extent. In addition to this, zero infrastructure investment is also possible for organizations in most cases.
Q22. How private cloud and community cloud infrastructure are different from one another?
A private cloud is actually an option for 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 met. The 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 are the sole responsibility of their own. The community cloud infrastructure can also be in a remote data center that can be accessed easily.
Q23. Tell something about the deployment options you are familiar with which are common in cloud technology?
It is not always necessary that a deployment model that is good for one organization also offers the 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, the public cloud is a good option for organizations with small size.
Q24. Name the common layers which are present in cloud architecture?
- Cloud Controller
- Node Controller
- Storage Controller
Q25. In the hierarchy of cloud, which layer is at the top?
The controller is always at the top and it manages the network, server, API, as well as storage of data.
