Cloud Computing Questions And Answers PDF

What Is Cloud Computing?

Answer : The cloud computing is the computing which is completely based on the Internet. It can also be defined as the next stage in the evolution of the Internet. The cloud computing uses the cloud (Internet) that provides the way to deliver the services whenever and wherever the user of the cloud needs. Companies use the cloud computing to fulfill the needs of their customers, partners, and providers. The cloud computing includes vendors, partners, and business leaders as the three major contributors. The vendors are the one who provide applications and their related technology, infrastructure, hardware, and integration. The partners are those who offer cloud services demand and provide support service to the customers. The business leaders are the ones who use or evaluate the cloud service provided by the partners. The cloud computing enables the companies to treat their resources as a pool and not as independent resources.

What Is A Cloud?

Answer : A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. It has broadly three users which are end user, business management user, and cloud service provider. The end user is the one who uses the services provided by the cloud. The business management user in the cloud takes the responsibility of the data and the services provided by the cloud. The cloud service provider is the one who takes care or is responsible for the maintenance of the IT assets of the cloud. The cloud acts as a common center for its users to fulfill their computing needs.

What Are The Basic Characteristics Of Cloud Computing?

Answer : The four basic characteristics of cloud computing are given as follows: • Elasticity and scalability. • Self-service provisioning and automatic de-provisioning. • Standardized interfaces. • Billing self-service based usage model.

What Is A Cloud Service?

Answer : A cloud service is a service that is used to build cloud applications. This service provides the facility of using the cloud application without installing it on the computer. It reduces the maintenance and support of the application as compared to those applications that are not developed using the cloud service. The different kinds of users can use the application from the cloud service, which may be public or private application.

What Are Main Features Of Cloud Services?

Answer : Some important features of the cloud service are given as follows: 

• Accessing and managing the commercial software.

Why Does An Organization Need To Manage The Workloads?

Answer : The workload can be defined as an independent service or a set of code that can be executed. It can be everything from a data-intensive workload to storage or a transaction processing workload and does not rely upon the outside elements. The workload can be considered as a small or complete application. The organization manages workloads because of the following reasons: • To know how their applications are running. • To know what functions they are performing. • To know the charges of the individual department according to the use of the service.

Which Services Are Provided By Window Azure Operating System?

Explain Hybrid And Community Cloud.

Answer : The hybrid cloud consists of multiple service providers. This model integrates various cloud services for Hybrid Web hosting. It is basically a combination of private and public cloud features. It is used by the company when a company has requirements for both the private and public clouds. Consider an example when an organization wants to implement the SaaS (Software as a Service) application throughout the company. The implementation requires security that can be provided by the private cloud used inside the firewall. The additional security can be provided by the VPN on requirement. Now, the organization has both the private and public cloud features. The community cloud provides a number of benefits, such as privacy and security. This model, which is quite expensive, is used when the organizations having common goals and requirements are ready to share the benefits of the cloud service.

Fabric for development and testing of services before their deployment on the Windows Azure in the cloud.

What Are The Advantages Of Cloud Services?

Answer : Some of the advantages of cloud service are given as follows: • Helps in the utilization of investment in the corporate sector; and therefore, is cost saving. • Helps in the developing scalable and robust applications. Previously, the scaling took months, but now, scaling takes less time. • Helps in saving time in terms of deployment and maintenance.

What Are The Concerns Prevailing Around Cloud Computing?

Answer : Security of data is the topmost concern in the consumers minds.

How Can These Concerns Be Addressed?

Answer : By offering a more expensive - private cloud - solution, a customer's data is isolated from the public. Virtual private clouds can also be implemented. Lastly, a poorest measure against security is client-partitioning in a public cloud.

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.

What Is The Difference Between Scalability And Elasticity?

Answer : Scalability is a characteristic of cloud computing through which increasing workload can be handled by increasing in proportion the amount of resource capacity. It allows the architecture to provide on demand resources if the requirement is being raised by the traffic. Whereas, elasticity is being one of the characteristic provide the concept of commissioning and decommissioning of large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources.

What Are The Different Layers Of Cloud Computing?

Answer : Cloud computing consists of 3 layers in the hierarchy and these are as follows:

Infrastructure as a Service (IaaS) provides cloud infrastructure in terms of hardware like memory, processor speed etc.

Platform as a Service (PaaS) provides cloud application platform for the developers.

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.

What Resources Are Provided By Infrastructure As A Service?

Answer : Infrastructure as a Service provides physical and virtual resources that are used to build a cloud. Infrastructure deals with the complexities of maintaining and deploying of the services provided by this layer. The infrastructure here is the servers, storage and other hardware systems.
