FRESHERS INTERVIEW Q&A – Cloud Part 2

1. What is Cloud Technology?
A Cloud is a virtual space on the internet where users can store digital resources like software, applications, and files. Cloud technology allows computing services including servers, networks, storage, databases, software, analytics, and intelligence to be delivered over the internet. Users can share digital resources across the internet without the restriction of physical location.

2. What are the main features of Cloud Computing?
The main features of cloud computing are:
Agility – Huge amounts of computing resources can be provisioned in minutes
Location Independence – Resources can be accessed from anywhere with an internet connection
Better Storage – with cloud storage, there are no limitations of capacity like in physical devices
Multi-Tenancy – resource sharing is possible among a large group of users
Reliability – data backup and disaster recovery become easier and less expensive with cloud computing
Scalability – Cloud allows businesses to scale up and scale down as and when needed

3. What are Cloud Delivery Models?
Cloud Delivery models are categories of cloud computing, including:
Infrastructure as a Service (IaaS) – the delivery of services like servers, storage, networks, operating systems on request basis.
Platform as a Service (PaaS) – it combines IaaS with an abstracted collection of middleware services, software development, deployment tools. PaaS helps developers to quickly create web or mobile apps on a cloud.
Software as a Service (SaaS) – software applications are delivered on-demand, in a multi-tenant model
Function as a Service (FaaS) – allows end-users to build and run app functionalities on a serverless architecture

4. What are the different versions of the Cloud?
There are different models to deploy cloud services:
Public Cloud – the set of computer resources like hardware, software, servers, storage, etc., owned and operated by third-party cloud providers for use by businesses or individuals.
Private Cloud – a set of resources owned and operated by an organization for use by its staff, partners, or customers.
Hybrid Cloud – a combination of public and private cloud services.

5. Name the main constituents of the Cloud ecosystem.
Cloud Consumers
Direct Customers
Cloud Service Providers

Private Cloud – a set of resources owned and operated by an organization for use by its staff, partners, or customers.
Hybrid Cloud – a combination of public and private cloud services.
5. Name the main constituents of the Cloud ecosystem.
Cloud Consumers
Direct Customers
Cloud Service Providers

6. Who are the cloud service providers?
Cloud service providers are the commercial vendors or companies that develop their own cloud services capabilities and sell the services to cloud consumers.

7. Who are Direct Customers?
Direct customers are users who often use the services developed by your business within a cloud environment. They do not know if you’re using a public or private cloud.

8. Who are cloud consumers?
Cloud consumers are the individuals or groups within a business unit that use the various cloud services provided to get a task done.

9. Describe the Cloud Computing Architecture
Cloud computing architecture is divided into:
Front end – used by the client and consisting of client-side interfaces and applications needed to access cloud computing platforms. It includes web servers like Chrome, Firefox, tablets, mobile devices.
Back end – used by a service provider to manage all resources needed for providing Cloud computing services. Includes data storage, virtual machines, servers, deploying models, etc.
The different components of the cloud architecture are:
Client Infrastructure – provides GUI for cloud interaction
Application – software or platform
Service – a type of service accessed

10. What are the Cloud Storage Levels?
The common levels of cloud data storage are:
Files
Blocks
Datasets
Objects

11. Name the serverless components in cloud computing.
Serverless components enable users to create applications without the complexity of managing physical infrastructure. Codes can be written without the provision for a server.
Serverless machines tend to virtual machines and container management.
Serverless components also take care of multi-threading hardware allocation.

12. List the advantages and disadvantages of serverless computing.
Advantages:
Cost-effective
Simplified operations
Increases Productivity
Scalable
Disadvantages:
Can cause latency in response
Not suited for high-computing operations due to resource limitations
Not very secure
Debugging can be challenging

13. What are cloud-enabling technologies?
Broadband Networks
Virtualization
Data Centre
Web Technology
Multitenant Technology
Service Technology

14. Define microservices.
Microservices is the process of creating applications that include code that is independent of each other and of the inherent developing platform.

15. Discuss the importance of microservices for a true cloud environment.
Microservices provide benefits like:
A microservice is designed to serve a specific purpose, so application development becomes simple.
It is easier and faster to make code changes using microservices because the changes are smaller and simpler compared to a complex integrated application.
They are scalable; hence easy to deploy additional instances or change of service.
A microservice is fully tested and validated. Thus, developers can presume the integrity of new applications without continual testing.
