Below are some important Cloud Computing interview questions which are asked in most MNC company interviews for beginners or professionals.
21. Is Cloud computing an application?
The Cloud Computing is not an application but it is a methodology that deploys application in a custom fashion on a server. It can be also learned as an advance model of client-server architecture that is highly flexible, scalable and configurable. This architecture leverages high performance out of machines with quite an ease of management.
22. What do you understand by CaaS?
CaaS is a terminology given in telecom industry as Communication as a Service. The Voice-over-Ip (VoIP) follows a same delivery model. CaaS can offer the enterprise user features such as desktop call control, presence, unified messaging, and desktop faxing. In addition to the enterprise features, CaaS also has a set of services for contact center automation that includes IVR, ACD, call recording, multimedia routing (e-mail and text chat), and screen pop integration.
23. How does cloud computing provides on-demand functionality?
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.
24. What is the difference between scalability and elasticity?
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.
25. What are the different datacenters deployed for this?
Cloud computing is made up of various datacenters put together in a grid form. It consists of different datacenters like:
- Containerized Datacenters
These are the traditional datacenters that allow high level of customization with servers, mainframe and other resources. It requires planning, cooling, networking and power to access and work.
- Low-Density Datacenters
These datacenters are optimized to give high performance. In these datacenters the space constraint is being removed and there is an increased density. It has a drawback that with high density the heat issue also creeps in. These datacenters are very much suitable to develop the cloud infrastructure.
