Cloud Interview Questions and Answers
Question - 11 : - List the platforms which are used for large-scale cloud computing.
Answer - 11 : -
The timely processing of massive digital collections demands large-scale distributed computing resources and the flexibility to customize the processing performed on the collections.
The platforms that are used for large-scale cloud computing are:
Question - 12 : - Mention the different types of models used for deployment in cloud computing.
Answer - 12 : -
You need the perfect cloud deployment model to help you gain a competitive edge in the market. You will have access to IT resources and services that can make your business flexible and agile, both concerning volume and scale.
The different deployment models in cloud computing are:
- Private Cloud
- Public Cloud
- Community Cloud
- Hybrid Cloud
Question - 13 : - What are the different versions of the cloud?
Answer - 13 : -
There are two primary deployment models of the cloud: Public and Private.
Public Cloud: The set of hardware, networking, storage, services, applications, and interfaces owned and operated by a third party for use by other companies or individuals is the public cloud. These commercial providers create a highly scalable data center that hides the details of the underlying infrastructure from the consumer. Public clouds are viable because they offer many options for computing, storage, and a rich set of other services.
Private Cloud: The set of hardware, networking, storage, services, applications, and interfaces owned and operated by an organization for the use of its employees, partners, or customers is the private cloud. This can be created and managed by a third party for the exclusive use of one enterprise. The private cloud is a highly controlled environment not open for public consumption. Thus, it sits behind a firewall.
Hybrid Cloud: Most companies use a combination of private computing resources and public services, called the hybrid cloud environment.
Multi-Cloud: Some companies, in addition, also use a variety of public cloud services to support the different developer and business units – called a multi-cloud environment.
Question - 14 : - What are the main constituents that are part of the cloud ecosystem?
Answer - 14 : -
The parts of the cloud ecosystem that determine how you view the cloud architecture are:
- Cloud consumers
- Direct customers
- Cloud service providers
Question - 15 : - Who are the Cloud Consumers in a cloud ecosystem?
Answer - 15 : -
The individuals and groups within your business unit that use different types of cloud services to get a task accomplished. A cloud consumer could be a developer using compute services from a public cloud.
Question - 16 : - Who are the Direct customers in a cloud ecosystem?
Answer - 16 : -
Users who often take advantage of services that your business has created within a cloud environment. The end-users of your service have no idea that you’re using a public or private cloud. As long as the users are concerned, they’re interacting directly with the services and value.
Question - 17 : - Who are the Cloud service providers in a cloud ecosystem?
Answer - 17 : -
Cloud service providers are the commercial vendors or companies that create their own capabilities. The commercial vendors sell their services to cloud consumers. In contrast to this, a company might decide to become an internal cloud service provider to its own partners, employees, and customers, either as an internal service or as a profit center. Cloud service providers also create applications or services for such environments.
Question - 18 : - What are the Cloud Storage Levels?
Answer - 18 : -
Cloud storage device mechanisms provide common levels of data storage, such as:
- Files – These are collections of data that are grouped into files that are located in folders.
- Blocks – A block is the smallest unit of data that is individually accessible. It is the lowest level of storage and the closest to the hardware.
- Datasets – Data sets organized into a table-based, delimited, or record format.
- Objects – Data and the associated metadata with it are organized as web-based resources.
Each of the above data storage levels is associated with a certain type of technical interface. This interface corresponds to a particular type of cloud storage device and the cloud storage service used to expose its API.
Question - 19 : - What are Cloud-Native Applications?
Answer - 19 : -
‘Cloud native’ is a software framework designed with containers, microservices, dynamic orchestration, and also continuous delivery of software. Every part of the cloud-native application has within it its own container and is dynamically orchestrated with other containers to optimize the way the resources are utilized.
Question - 20 : - How does the Polling Agent monitor cloud usage?
Answer - 20 : -
A processing module that gathers cloud service usage data by polling IT resources is called a polling agent. The polling agent has also been used to timely monitor the IT resource status, like uptime and downtime.
Each of these can be designed to forward collected usage data to a log database for post-processing and for reporting purposes.
