Can you name a single organization that is not using cloud computing?
You can’t. Because there isn’t any.
Although the concept of cloud computing has been vaguely on board since 70’s, the journey started full-fledged with the invention of Amazon Web Services in 2006. Cloud computing provides agility for the organization, helps in cost reduction, monitors the performance of an entire organization. With the help of cloud computing, productivity gets increased as well when multiple users can work on the same data simultaneously, rather than waiting for it to be saved and emailed. Time may be saved as information does not need to be re-entered when fields are matched, nor do users need to install application software upgrades to their computer. Is there any reason for any business in the world for not benefitting themselves from this? Not a chance!
A career in cloud computing is pretty promising. But, you’ll need to go through a bunch of basic questions at the interview table to grab one. What they might be you wonder? Let’s check these 20 mostly asked cloud computing questions for the clarification!
Cloud computing is referred to the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, it may be designated an edge server.
The benefits of cloud computing are:
A cloud is a collection of the network, hardware, services, storage, and interfaces that helps in delivering computing as a service. Cloud has three users :
Some of the different data types in cloud computing are mentioned below:
The different layers that are used by cloud architecture are:
The 2 platforms mainly used for large scale cloud computing are:
Cloud Computing has 3 different layers in the hierarchy:
Infrastructure as a service (IaaS): Provides cloud infrastructure in the basis of hardware like memory, processor, speed etc.
Platform as a service (PaaS): Provides a cloud application platform for the cloud developer.
Software as a service (SaaS):: Provides users with cloud applications directly without installing anything on the system.
Software As a Service (SaaS) is a vital layer of cloud computing that facilitates users to save and create their documents on the cloud.
Platform as a Service or PaaS is a layer in a cloud architecture that is built on the infrastructure model and provide resources like computers, storage, and network. PaaS provides complete virtualization of the infrastructure layer and makes it look like a single server and invisible for the outside world.
Cloud computing provides on-demand access to virtualized IT resources which is known as on-demand functionality. It can be used by the subscriber by a shared pool to provide configurable resources. This shared pool contains networks, servers, storage, applications, and services.
Apache Hadoop and MapReduce platforms can be used for large scale cloud computing.
The different deployment model in cloud computing are:
The different deployment model in cloud computing are:
Private clouds secure strategic operations and other reasons. It is a complete platform that is fully functional and can be owned, operated and restricted by that particular organization only. In the present day, most of the organizations have moved to private clouds due to security concerns. Virtual private cloud is being used that operate by a hosting company.
Public clouds are open for users to use and deploy that focuses on a few layers like cloud application, an infrastructure providing, and providing platform markets.
Hybrid clouds are a combination of public clouds and private clouds. Most of the people are preferring Hybrid Clouds over both public and private clouds because it applies most robust approach to implement cloud architecture. It includes the functionalities and features of both the worlds. It allows organizations to create their own cloud and allow them to give control over to someone else as well.
Mobile computing’s concept is based on cloud computing. Cloud computing provides users the required data. On the other hand, in mobile computing, applications run on the remote server and give the user access for storage and management.
Scalability is a characteristic of cloud computing that handles the increasing workload by increasing the amount of resource capacity. With the use of scalability, the architecture provides on-demand resources if the requirement is being raised by the traffic. On the other hand, Elasticity is a characteristic that provides the concept of commissioning and decommissioning of a large amount of resource capacity. It is measured by the speed through which the resources are coming on demand and the usage of the resources.
Cloud computing maintains the authorization of the application services. That’s the reason it is used in identity management.
It also provides allows the users to control the access of another user who is entering into the cloud environment.
Utility computing is a plug-in under a particular organization’s management that decides the type of services to be deployed from the cloud. It allows users to pay only for what they use.
It is an acronym stands for Elastic Utility Computing Architecture For Linking Your Program To Useful Systems. EUCALYPTUS is an open-source software infrastructure in cloud computing for the implementation of clusters in the cloud computing platform. It creates a public, private, and hybrid clouds and allows a user to create his own data center into a private cloud and use its functionalities to many other organizations.
