In this blog, we’ve laid out five winning interview questions that will help set the pace for cloud computing and help you succeed in your next cloud interview.

Q1:- What are the different cloud delivery models?

Answer:- The model used to represent the computing environment is called the cloud delivery model. There are three main types of cloud delivery models on the market: SaaS, IaaS and PaaS. All models have their own advantages that distinguish them from others in terms of characteristics and application.

Let’s go deeper into each!

• Software as a Service (SaaS): Software as a Service (SaaS) is a service delivery paradigm closely related to application service providers (ASP) and on-demand computing software delivery models. It provides a cloud platform where customer applications are created and hosted in a multi-tenant model by third-party providers. SaaS makes these applications available over the Internet with no additional installation required.

  Common examples of SaaS applications used for business technology include email, customer relationship management (CRM), sales management, human resources management (HRM), financial management, billing, and collaboration.

• Infrastructure as a Service (IaaS): Infrastructure as a Service (IaaS) is one of three major categories of cloud computing services that provide physical and virtual computing resources over the Internet. IaaS gives businesses access without purchasing hardware resources. The infrastructure provided by IaaS includes an operating system, database storage, networking, and optionally many other utility software elements.

• Platform as a Service (PaaS): Platform as a Service (PaaS) is an important category of cloud computing services that offers organizations a consistent way to create and deploy applications in cloud or on-premises environments. This layer is completely dependent on your infrastructure model. This is combined with a set of abstracted middleware services to give customers a platform on which to develop, run and manage applications without the complexity of building and maintaining infrastructure.

Q2- Describe hybrid, public and private clouds. Also compare in terms of safety.

Answer:- There are three main deployment models in cloud: public cloud, private cloud and hybrid cloud. Let’s look at each type of cloud one by one!

Public cloud: A public cloud is nothing but a set of hardware, software, networking, storage, services, applications, and other ancillary infrastructure owned and operated by third-party providers for use by individuals or other businesses. To ensure data security, third-party providers utilize highly scalable data centers and hide the details of the underlying infrastructure. These clouds are open for anyone to use and deploy. Share the same hardware with multiple partners and access services via a web browser. The public cloud is ideal for large amounts of data and fluctuating demand. Examples:- Google, Amazon, and Microsoft Azure.

Private cloud: A private cloud is a set of hardware, software, networking, storage, services, applications, and other ancillary infrastructure owned and operated by a company for the sole use of its customers, partners, or employees. A private cloud is used only by his one organization on its own private network. Most of the IT industry uses private clouds to ensure the privacy of organizations and customers and keep their networks away from public clouds. Private clouds are not public. Therefore, it is expected to be used in government agencies. Private clouds are best when usage patterns are predictable and users are predefined.

Hybrid cloud: A private cloud is nothing more than a combination of a public cloud and a private cloud. Hybrid cloud environments combine on-premises computing, storage, and data to drive cloud demand. This cloud combines the features and capabilities of both clouds and applies the most robust approach to implementing cloud architecture. Hybrid clouds allow industries to create their own clouds and hand over control to other organizations and individuals.

Data safety/security is an organization’s primary concern whenever technology is selected. Let’s compare!

• public cloud:- These clouds have a huge number of customers and a large number of access points, so they pose different security threats. To keep your data safe, you typically separate security responsibilities, assigning workload security to tenants and infrastructure security to providers.

• private cloud:- Private clouds are relatively more secure than public clouds because they run behind your firewall, but they only rely on your organization’s internal security.

• hybrid cloud:- A hybrid cloud is the most secure as it combines the best features of both clouds. Considered the most secure as users and administrators can reduce data exposure by transferring workloads and data between environments depending on security requirements, compliance, policy or audit .

Q3:- Name some popular cloud computing services.

Answer:- The use of cloud computing is gradually increasing as it improves the bottom line performance of the business. As the demand for cloud technology increases, the number of cloud service providers and platforms has also increased significantly. Well-known players include Amazon Web Services (AWS), Windows Azure, IBM Cloud, and Oracle Cloud.

With so many providers competing for ratings, choosing the right cloud computing service for your business can be difficult. The only thing you should focus on when choosing a compute service is what you need it to do. With a clear business model, you can choose the best service that matches the functionality and actual requirements of your requirements. Below are the most commonly used large cloud providers.

• Hoster

• google big table

• alibaba cloud

• Amazon SimpleDB

• cloud-based SQL

Q4:- Please describe the security aspects of cloud computing.

Answer:- Cloud is the most trending technology, it enhances platform quality and improves data delivery speed. But security is a major concern of all giants as they move data from one platform to another. When talking about cloud environments, there are multiple security levels to consider.

• Identity management: This level of security requires authorized users to use hardware components or application services.

• Access control: At this level, application service permissions are provided to the customer so that the enterprise can control and access other users connected to the same cloud environment. The user must have permission to manage access for other users to join the environment.

• Authorization and certification: Allow only authenticated and authorized users to modify or access applications and data.

Q5:- Describe the migration from traditional on-premises computing to cloud computing.

Answer:- Cloud computing represents a major shift away from traditional on-premises computing for many industries that see data as a key factor. Cloud computing aims to improve the ultimate performance of business in various aspects such as cost, performance, security, speed and productivity. Let’s discuss the main reasons for this transition.

price:- Cost is considered one of the most controversial factors when comparing cloud and traditional computing. People usually think of cloud as a costly technology, but there are scenarios where cloud proves to be cheaper. When a project requires a supercomputer, a large number of CPUs, etc., cloud computing delivers value by eliminating the costs of purchasing software, hardware, racks of servers, and data center placement.

Cloud computing eliminates IT teams for infrastructure management and reduces power consumption for power and cooling.

speed:- Cloud computing delivers data much faster than traditional computing because you don’t have to search multiple data centers or migrate hardware. It also offers on-demand and self-service so your organization can work accordingly. Delivering humorous data in minutes/seconds provides organizations with greater flexibility and increases productivity.

Productivity:- When we talk about productivity, the first thing that comes to mind is maintenance.Traditional Computing requires regular system health checks and upgrades according to business requirements. This update process took a lot of time and all my previously configured settings were lost after a successful upgrade. But with cloud computing, everything is automated here, so you don’t have to worry about upgrades or maintenance. This automation helps IT hubs achieve business goals and improve productivity.

Performance: System performance is always important. Because it depends on hardware, software and servers. Unlike on-premises computing, cloud computing doesn’t cost you upgrades, so system performance doesn’t suffer. At the cloud end, you can use GPUs whenever you need them and pay only for what you use. This helps organizations prevent slow performance and frequent interruptions.
