What is Hypervisor in Cloud Computing and its types?

Correct Answer: Eucalyptus stands for ?Elastic Utility Computing Architecture for Linking Your Programs to Useful Systems? and provides an open source software infrastructure to implement clusters in cloud computing platform It is used to build private, public and hybrid clouds It can also produce your own datacenter into a private cloud and allow you to extend the functionality to many other organizations Eucalyptus provides APIs to be used with the web services to cope up with the demand of resources used in the private clouds

Correct Answer: Cloud computing is going all together for a different look as it now includes different data types like emails, contracts, images, blogs, etc The amount of data increasing day by day and cloud computing is requiring new and efficient data types to store them For example if you want to save video then you need a data type to save that Latency requirements are increasing as the demand is increasing Companies are going for lower latency for many applications

Correct Answer: API stands for Application programming interface is very useful in cloud platforms as it allows easy implementation of it on the system It removes the need to write full fledged programs It provides the instructions to make the communication between one or more applications It also allows easy to create application with ease and link the cloud services with other systems

Correct Answer: Cloud computing is a metaphor used for internet It provides on-demand access to virtualized IT resources that can be shared by others or subscribed by you It provides an easy way to provide configurable resources by taking it from a shared pool The pool consists of networks, servers, storage, applications and services

Correct Answer: Cloud computing consists of 3 layers in the hierarchy and these are as follows: 1 Infrastructure as a Service (IaaS) provides cloud infrastructure in terms of hardware like memory, processor speed etc 2 Platform as a Service (PaaS) provides cloud application platform for the developers 3 Software as a Service (SaaS) provides cloud applications which are used by the user directly without installing anything on the system The application remains on the cloud and it can be saved and edited in there only

Correct Answer: It depends on the type of business that demands a cloud setup Suppose if the subscription on a public cloud for an application that is to be deployed on OS images is proving to be more costly then to buy some new datacenters and maintain them Then obviously the a private cloud has to be setup instead of a public cloud This public clouds follow utility billing methodology as electricity bill for example

Correct Answer: Cloud architecture provide large pool of dynamic resources that can be accessed any time whenever there is a requirement, which is not being given by the traditional architecture In traditional architecture it is not possible to dynamically associate a machine with the rising demand of infrastructure and the services Cloud architecture provides scalable properties to meet the high demand of infrastructure and provide on-demand access to the user

Correct Answer: - Cloud architecture uses simple APIs to provide easily accessible services to the user through the internet medium - It provides scale on demand feature to increase the industrial strength - It provides the transparency between the machines so that users don?t have to worry about their data Users can just perform the functionality without even knowing the complex logics implemented in cloud architecture - It provides highest optimization and utilization in the cloud platform

Correct Answer: Service oriented architecture (SOA) is an architectural style that supports service oriented methodology that is being added in the cloud architecture as a mandatory component Cloud architecture support the use of on-demand access to resources and it provides lots of other facilities that are being found in SOA as well SOA makes these requirements optional to use But, to get the full functionality and more performance based efficiency there is a requirement for the mixture of SOA and cloud architecture

Correct Answer: Amazon web services consist of a component called as Amazon S3 that acts as a input as well used as an output data store It is used in checking the input and according to that gives the output The input consists of the web that is stored on Amazon S3 as object and it is update frequently to make the changes in the whole architecture It is required due to the on demand growing of the data set and to provide persistent storage
