How does cloud architecture overcome the difficulties faced by traditional architecture?

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: 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 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

Correct Answer: Amazon S3 provides uploading of large files and retrieve small offsets for end-to-end transfer data rates The large file gets stored into small files that are smaller in size Amazon S3 stores multiple of files together in a bundle or in a compressed form, For example in gzip or gz format and then convert them into Amazon S3 objects The files get uploaded on the Amazon server by the use of FTP or another protocol and then retrieved through the HTTP GET request The request includes the defined parameters like URL, offset (byte-range) and size (length)
