Is it cost effective to implement a private cloud rather than a public cloud and why?

Correct Answer: The hypervisor is a virtual machine monitor (VMM) that manages resources for virtual machines The name hypervisor is suggested as it is a supervisory tool for the virtual machines There are mainly two types of hypervisors : - Type-1: the guest Vm runs directly over the host hardware, eg Xen, Hyper-V, VmWare ESXi - Type-2: the guest Vm runs over hardware through a host OS, eg Kvm, Oracle virtualbox

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 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

Correct Answer: Every architecture rely on a database that is easy to maintain and gets easily configured Amazon uses the database by the name SimpleDB This is the database that is used for cloud architecture to track the statuses of the components The component of the system are asynchronous and discrete, it requires capturing the state of the system so that in any failure the user can easily revert back to its normal configuration SimpleDB is schema-less database and there is no need to define the structure before the creation of any data Every controller in the database defines their own structure and link the data to a job
