These are some of the main features of Azure, but the platform offers a wide range of other services and solutions to meet various business needs.

What is the difference between IaaS, PaaS, and SaaS in the context of Azure?

IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service) are different cloud computing service models provided by Azure.

IaaS provides the infrastructure components such as virtual machines, storage, and networking, allowing customers to deploy and manage their own operating systems, middleware, and applications.

PaaS provides a platform for customers to develop, run, and manage their applications, without having to worry about infrastructure management. PaaS includes services such as Azure App Service, Azure Functions, and Azure Container Service.

SaaS provides fully managed software applications over the internet, requiring no installation or maintenance by the customer. Examples of SaaS offerings on Azure include Office 365, Dynamics 365, and Power BI.

In summary, IaaS provides the lowest level of abstraction and the greatest level of control, while SaaS provides the highest level of abstraction and the least level of control. PaaS is a middle ground, offering a balance of control and abstraction.

How does Azure provide security and privacy for its customers?

Azure provides security and privacy to its customers through a multi-layered approach that includes physical, operational, and network security, as well as data encryption and access control. Some of the key security features in Azure include:

The following are the most prevalent Azure pricing options:

• Consumption-based pricing entails just paying for what you consume. The Pay-As-You-Go rate is another name for this model.
• Fixed price – You furnish resources and are charged regardless of whether they are utilised.
• Workloads on a peak throughput are a frequent approach to assess cost. Consumption-based pricing may be less efficient for determining baseline costs under consistently high utilisation as compared to similar provided pricing. PaaS and serverless technologies can assist you in determining the economic threshold for consumption-based pricing.

22. Define  IaaS.

Infrastructure as a service (IaaS) is a sort of cloud computing service that provides on-demand computation, storage, and networking resources on a pay-as-you-go basis. IaaS, along with software as a service (SaaS), platform as a service (PaaS), and serverless, is one of four categories of cloud services.

By adopting IaaS, you may avoid the cost and complexity of owning and operating physical servers and datacenter infrastructure. Each resource is delivered as a distinct service component, and you only pay for what you need.

23. Explain the Public cloud.

The public cloud is described as computing services provided by third-party providers over the public Internet to anyone who wishes to use or purchase them. They can be free or paid for on a per-use basis, allowing consumers to pay only for the CPU cycles, storage, or bandwidth they use.

24. Contrast and compare the three types of cloud computing.

• The first type of cloud computing is infrastructure as a service (IaaS), which provides Internet-based storage and processing capacity. IaaS, the most basic sort of cloud computing, allows you to rent IT infrastructure – servers and virtual machines, storage, networks, and operating systems – on a pay-as-you-go basis from a cloud provider.
• The second sort of cloud computing is platform as a service (PaaS), which provides developers with the tools they need to create and run web applications. PaaS is intend to provide customers with access to the components needed to swiftly construct and operate online or mobile apps over the Internet, without the need to set up or manage the underlying infrastructure of servers, storage, networks, and databases.
• Software as a service (SaaS), which is used for web-based applications, is the third cloud computing category. SaaS is a technique of providing software applications over the Internet in which cloud providers host and administer the software applications, allowing you to have the same programme on all of your devices at the same time by accessing it in the cloud.

25. What is Azure Resource Manager?

Azure Resource Manager is the Azure deployment and management service. It offers a management layer via which you may add, update, and delete resources in your Azure account. After deployment, you use management tools such as access control, locks, and tags to secure and organise your resources.

In Azure, a cloud service can transport several web apps, characterizing a number of sections to disseminate handling and allow for flexible expansion of your program. A cloud service is of at least one online portion as well as special sections, each having its own set of application papers and designs. The primary advantage of cloud services is their ability to assist more sophisticated multilayer structures.

29. What is the distinction between a public cloud and a private cloud?

Private clouds are those that are built specifically for a single business. They allow a company to run applications on the cloud while also addressing data security and control issues that are common in a public cloud environment.

30. Define  Network Security Group.

The Network Security Group (NSG) is a collection of ACL rules that allow or restrict network traffic to subnets, network interface cards (NICs) connected to a subnet, or both. When an NSG connects to a subnet, the ACL rules apply to all virtual machines on that subnet. The traffic limits to a single NIC are accomplish by connecting the NSG directly to that NIC.

31. What is the Azure storage key?

Depending on the project needs, an Azure storage key is require to authenticate access to Azure storage service data. For authentication, there are two types of storage keys:

• Firstly,The primary access code
• Secondary access key, to avoid website or application downtime

32. Explain Windows Azure Portal.

To run an application, a designer logs in to the Windows Azure Portal using their or her web program using a Windows Live ID. At that point, the user must decide whether to create a hosting account for running programs, a storage account for storing data, or both.

Once the designer has a hosting account, he or she can submit applications to Windows Azure via a Windows Azure Portal.
