Cloud Computing Basics

Azure Basics

Commonly asked Azure interview questions. Please share this page if you find these Azure resources useful.

1. What is Cloud Computing?

Cloud Computing is the delivery of Computing services-including servers, storage, databases, networking, software over the Internet to offer faster innovation, flexible resources, and economies.

2. Types of Cloud Computing?

There are three types of Cloud Computing. They are private cloud, public cloud, and hybrid cloud.

3. What is azure?

Azure is a huge collection of servers and networking hardware, which runs a complex set of distributed applications.

4. What is Azure used For?

Microsoft Azure, formerly known as Windows Azure, is Microsoft's public cloud computing platform. It provides a range of cloud services, including compute, analytics, storage and networking.

5. How Azure works?

Once customers subscribe to Azure, they have access to all the services Avilable in the Azure portal. Subscribers can use these services to create cloud-based resources, such as virtual machines (VM) and databases.

6. What is compute in Microsoft Azure?

Azure compute services are the hosting services responsible for building new applications or deploying existing ones. Azure compute provides the infrastructure you need to run your applications, these include Azure Virtual Machines (VMs), Azure Container Service, Azure App Services, Azure Batch.

7. What is Azure Virtual Machine (VM)?

An Azure virtual machine is an on-demand and scalable computer resource that is available in Azure and used to host applications when the customer requires more control over the computing environment than what is offered by other compute resources.

8. What are different types of Azure Virtual Machines?

• General-purpose
• Compute-optimized VMs
• Memory-optimized VMs
• Storage optimized VMs
• VMs for Graphics Processing( GPUs)

9. What are the benefits of Azure Virtual Machines?

• High Availability
• High Security
• Scalability

10. What is Serverless computing in Azure?

Serverless computing enables developers to build applications faster by eliminating the need for them to manage infrastructure. With serverless applications, the cloud service provider automatically provisions, scales and manages the infrastructure required to run the code.

11. What are examples of serverless computing?

AWS Lambda, Microsoft Azure Functions, Google Cloud Functions and IBM OpenWhisk are all well-known examples of serverless services offered by the cloud providers.

12. What are the different ways in which cloud services are provided?

• IAAS - Infrastructure as a Service
• PAAS - Platform as a Service
• SAAS - Software as a Service
• CAAS - Containers as a Service
• FAAS - Functions as a Service (also called Serverless Computing)

13. What is Infrastructure as a Service (IAAS)?

As the name implies, with Infrastructure as a Service, you rent or lease IT infrastructure (think of it as renting IT hardware) from a cloud service provider like Microsoft Azure, Google Cloud Provider, Amazon Web Services or some other cloud provider.

With Infrastructure as a Service (IAAS), the cloud service provider procures and manages the infrastructure at their data center. You as the client, rent or lease this infrastructure over the internet or through a virtual private network. For the duration that you use the infrastructure, you pay a fee. You are only charged based on the number of machines and resources that are actually being used. Infrastructure as a service (IaaS) is also known as hardware as a service (HaaS).

14. What is a VPN (Virtual Private Network)?

A Virtual Private Network is dedicated and secure private tunnel between you (i.e your organization) and the cloud service provider.

15. Who uses Infrastructure as a Service (IaaS)?

In most organisations, it is the Infrastructure team that procures servers, and computers. Install software and provide systems to employees. Set up and manage networks. So in most cases, it is usually your infrastructure team that uses Infrastructure as a Service (IaaS). Sometimes, even software developments teams use this service if they want to have enhanced control over the underlying hardware and network.

Infrastructure as a Service supports a diverse set of use cases - computational or storage needs. For example, you have a web application which, you can host and run. You may also use it for your storage needs. For example, install SQL Server, Oracle or some other relational database and store your relational data.

16. What are the benefits of Infrastructure as a Service (IaaS)?

• Reduced financial risk for our organisation : Your organisation is launching a new product and for that you need a software application. You don't know if this will be a success or not. Instead of purchasing a physical server, all the related infrastructure and workforce to setup and maintain, you can rent or lease the infrastructure from a cloud service provider like Azure for as long as you need. If your new product launch or experiment succeeds, well and good. If it doesn't shut things down and you pay no longer. Straight away, you can see how organisations can benefit from the reduced financial risk. This encourages businesses to try new things, experiment and innovate more.
• Provision resources from geographically closer locations : Cloud service providers, for example, Amazon, Microsoft and Google, have data centers all over the world. This means, with the Infrastructure as a Service, you have the option of provisioning the servers from geographic locations close to your customers.
• Unlimited scalability : You almost will never run out of resources in a public cloud. It provides near unlimited scalability. You can set threshold limits to automatically scale up and down depending on the demand.
• Deployment Speed : Just imagine the time it takes to procure physical servers, storage and the related infrastructure. You need to purchase. Get them shipped over. Create a server room or data center. Secure it. Install power supply and cooling systems. Setup and configure network. The list goes on. You also need to hire skilled people to do all these. It takes a considerable amount of time to have all these in place. Probably days, sometimes even months in worst case scenarios.

  On the other hand, if you are using, Infrastructure as a Service, you point your browser to the cloud service provider web portal, and with a few clicks in just a few minutes you have one or many virtual machines procured. So you can see the speed with which we can procure and start using cloud infrastructure. So you really get time to focus on what matters to your business.
