What are some open source cloud computing platform databases?
Cloud computing platform has various databases that are in support. The opensource databases that are developed to support it is as follows:
1. MongoDB: is an open source database system which is schema free and document oriented database. It is written in C++ and provides tables and high storage space.
2. Couch DB: is an open source database system based on Apache server and used to store the data efficiently
3. Lucid DB: is the database made in Java/C++ for data warehousing. It provides features and functionalities to maintain data warehouse.
What essential things a user should know before going for cloud computing platform?
A user should know some parameters by which he can go for the cloud computing services. The parameters are as follows:
1. User should know the data integrity in cloud computing. It is a measure to ensure integrity like the data is accurate, complete and reasonable.
2. Compliance: user should make sure that proper rules and regulations are followed while implementing the structure.
3. Loss of data: user should know about the provisions that are provided in case of loss of data so that backup and recovery can be possible.
4. Business continuity plans: user should think about does the cloud services provide him uninterrupted data resources.
5. Uptime: user should know about the uptime the cloud computing platform provides and how helpful it is for the business.
6. Data storage costs: user should find out about the cost which you have to pay before you go for cloud computing.
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 tobe 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 datacentre 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 hierarchy which is used to manage the virtualized resources like servers, network and storage with the user APIs.
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 platform.
What is Hypervisor in Cloud Computing and its types?
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, e.g. Xen, Hyper-VMware ESXi Type-2: the guest Vm runs over hardware through a host OS, e.g Kvm, Oracle VirtualBox Are Type-1 Hypervisors better in performance than Type-2 Hypervisors and Why?
Yes the Type-1 Hypervisors are better in performance as compared to Type-2hypervisors because Type-1 hypervisors does not run through a host OS, they utilize all resources directly from Host hardware. In cloud implementation Type-1hypervisors are used rather than Type-2 because Cloud servers need to run multiple OS images and it should be noted that if OS images are run on host a OS as in case of Type-2, the resources will get wasted.
