Cloud Computing Basics Interview Questions

Cloud

computing is a rapidly growing field that has revolutionized the way businesses and individuals store, process, and manage data. As a result, there is a growing demand for professionals with expertise in cloud computing. In this article, we will cover some of the most common cloud computing basics interview questions that can help you prepare for your next interview.

What is Cloud Computing?

Cloud computing is a model of delivering computing services over the internet, where resources such as servers, storage, databases, software, and applications are provided as a service to users on-demand. Instead of having to manage and maintain their own hardware and software, users can access these resources on a pay-as-you-go basis, which reduces costs and increases flexibility.

Types of Cloud Computing

• Public Cloud:

  A public cloud is a cloud computing environment that is open to the general public and is owned by a third-party provider. Examples of public clouds include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

• Private Cloud: A private cloud is a cloud computing environment that is owned and managed by a single organization. It is typically more secure and customizable than a public cloud, but also more expensive.
• Hybrid Cloud: A hybrid cloud is a cloud computing environment that combines elements of both public and private clouds. It allows organizations to use public cloud services for certain workloads while keeping sensitive data and applications on a private cloud.

Cloud Computing Service Models

• IaaS (Infrastructure as a Service): IaaS provides virtualized computing resources, such as servers, storage, and networking, over the internet. Users can provision and manage these resources as if they were their own, but without the need to purchase and maintain the underlying hardware.
• PaaS (Platform as a Service): PaaS provides a complete development and deployment environment for applications, including tools, libraries, and infrastructure. Users can focus on writing code without worrying about the underlying infrastructure.
• SaaS (Software as a Service): SaaS provides software applications over the internet, eliminating the need for users to install, configure, and maintain software on their own devices.

Cloud Computing Deployment Models

• Multi-Cloud: A multi-cloud deployment model involves using multiple cloud providers to meet different business needs. This can provide greater flexibility and reduce dependence on a single provider.
• Single-Cloud: A single-cloud deployment model involves using a single cloud provider to meet all business needs. This can provide greater simplicity and cost savings.

Cloud Computing Security

Cloud computing security is a critical concern for organizations, as they need to ensure that their data and applications are protected from unauthorized access, theft, and damage. Some common cloud computing security measures include:

• Encryption: Encryption involves converting data into a code that can only be deciphered with a key or password.
• Access Control: Access control involves controlling who has access to cloud resources and what actions they can perform.
• Backup and Recovery: Backup and recovery involve creating copies of data and applications, and having a plan in place to restore them in case of a disaster.
