- It is the acronym for Elastic Utility Computing Architecture for Linking Your Programs.
21. How is EUCALYPTUS (Elastic Utility Computing Architecture for Linking Your Programs) used in cloud computing?
- Eucalyptus is mainly an open source software infrastructure which is used in cloud computing. It is usually used in implementing clusters in the cloud computing platform, in order to build public, hybrid and private clouds.
It can also produce its own data center into a private cloud and therefore, you will be allowed to use its functionalities to other organizations as well.
22. Why is a virtualization platform needed in implementing cloud?
- Cloud operating system
- In order to manage the service policies
- In order to keep the backend level and user level concepts different from each other
23. What are the various data centers deployed for cloud computing?
- Mainly two types of data centers are there for cloud computing, firstly low-density data centers, and secondly, containerized data centers
24. What are the applications of cloud computing?
- Cloud computing is a very speedy application process. Since you do not need to sell or buy anything in it; you can use the software in a convenient manner. The process of application building through this is 5 times faster and the applications can be deployed at anytime and anywhere. Additionally, it also instantly makes the applications mobile in nature.
25. What are the different modes of SaaS?
- There are two modes in Saas, and they are Fine grain multi-tenancy and simple multi-tenancy. In the case of the former, the resources are shared by many with the functionality remaining the same. On the other hand, in the latter case, every user has an independent resource and thus differs from other users. This is the reason why simple multiple tenancies are considered the most efficient mode.
26. What is the importance of PaaS?
- Platform as a Service or PaaS is very important in cloud computing. It provides the application platform for the providers. It facilitates the user with complete virtualization of the infrastructure layer and finally making it function like a single server.
27. What are the resources provided in IaaS?
- Infrastructure as a Service or IaaS provides the physical and virtual resources which are used to build a cloud, to the user. This layer of computing deals with the complexities of deployment and maintenance of the services provided by the same layer. The infrastructures consist of the servers, the hardware systems, and storage.
28. Define cloud service.
- A cloud service basically builds cloud applications. In simple words, one can use the applications even without installing them on the computer. As a result, the maintenance and support of the application are not required as compared to those applications that need to be installed on the computer in order to use them.
29. List main feature of cloud service
