What are system integrators?
Systems integrators are the important part of cloud computing platform. It
provides the strategy of the complicated process used to design a cloud
platform. It includes well defined architecture to find the resources and the
characteristics which have to be included for cloud computing. Integrators plan
the users cloud strategy implementation. Integrators have knowledge about data
center creation and also allow more accurate private and hybrid cloud creation.
What is the requirement of virtualization platforms in implementing cloud?
Virtualization is the basis of the cloud computing and there are many platforms
that are available like VMware is a technology that provides the provision to
create private cloud and provide a bridge to connect external cloud with
private cloud. There are three key features that have to be identified to make
a private cloud that is:
• Cloud operating system.
• Manage the Service level policies
• Virtualization keeps the user level and the backend level concepts different
from each other so that a seamless environment can be created between both.
What is the use of eucalyptus in cloud computing environment?
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.
Explain different layers which define cloud architecture
Cloud computing architecture consists of many layers which help it to be more
organized and can be managed from one place. The layers are as follows:
1. Cloud controller or CLC is the top most level in the hirerachy which is used
to manage the virtualized resources like servers, network and storage with the
2. Walrus is used for the storage and act as a storage controller to manage the
demands of the users. It maintains a scalable approach to control the virtual
machine images and user data.
3. Cluster Controller or CC is used to control all the virtual machines for
executions the virtual machines are stored on the nodes and manages the virtual
networking between Virtual machines and external users.
4. Storage Controller or SC provides a storage area in block form that are
dynamically attached by Virtual machines.
5. Node Controller or NC is at the lowest level and provides the functionality
of a hypervisor that controls the VMs activities, which includes execution,
management and termination of many instances.
How user will gain from utility computing?
Utility computing allow the user to pay per use means whatever they are using
only for that they have to pay. It is a plug in that needs to be managed by the
organizations on deciding what type of services has to be deployed from the
cloud. Utility computing allows the user to think and implement the services
according to them. Most organizations go for hybrid strategy that combines
internal delivered services that are hosted or outsourced services.
Is there any difference in cloud computing and computing for mobiles?
Mobile cloud computing uses the same concept but it just adds a device of
mobile. Cloud computing comes in action when a task or a data get kept on the
internet rather then individual devices. It provides users on demand access to
the data which they have to retrieve. Applications run on the remote server,
and then given to the user to be able to, store and manage it from the mobile
