INTRODUCTION – Introduction to Azure Fundamentals

This module provides a comprehensive introduction to the fundamentals of cloud computing and the Microsoft Azure platform. It covers essential concepts, helping you understand the core principles and benefits of cloud computing.

Additionally, the module offers detailed guidance on getting started with Azure, including how to set up and manage Azure subscriptions and accounts effectively. By the end of this module, you will have a solid foundation in cloud computing and be well-equipped to navigate and utilize Azure’s various services and features.

Learning Objectives

  • Describe the basic concepts of cloud computing.
  • Differentiate between the different methods of creating an Azure subscription.
  • Determine whether Azure is the right solution for your business needs.

KNOWLEDGE CHECK

1. Cloud computing is the delivery of computing services using a pay-as-you-go pricing model.

Which of the following statements are true of the pay-as-you-go pricing model? Select all options that apply.

  • You must pay a fixed fee in advance for all Cloud services.
  • You rent compute power and storage from someone else’s datacenter. (CORRECT)
  • You can immediately stop paying for resources that are no longer needed. (CORRECT)
  • You rent physical hardware such as compute power and storage and maintain them within your own datacenter.

Correct: Instead of maintaining CPUs and storage in your datacenter, you rent them for the time that you need them. The cloud provider takes care of maintaining the underlying infrastructure for you. 

Correct: You can treat cloud resources like you would resources in your own datacenter. When you are finished using them, you give them back. You are only billed for what you use.

2. Cloud Computing provides several benefits over a physical environment. Which of the following are benefits of cloud computing?

Select all options that apply.

  • High availability (CORRECT)
  • Agility (CORRECT)
  • Elasticity (CORRECT)
  • Full control 

Correct: Depending on the service-level agreement (SLA) that you choose, your cloud-based applications can provide a continuous user experience with no apparent downtime even when things go wrong.

Correct: Cloud-based resources can be deployed and configured quickly as your application requirements change.

Correct: Cloud-based applications can be configured to take advantage of autoscaling, so your applications will always have the resources they need.

3. Which of the following options is not defined as a type of cloud deployment model?

  • Public cloud
  • Private cloud
  • Distributed cloud (CORRECT)
  • Hybrid cloud

Correct: A distributed cloud is not a valid type of cloud computing. Distributed computing divides a single task among multiple computers that are connected via a network to achieve the task faster.

4. True or False?

The Azure Portal updates continuously and requires no downtime for maintenance activities.  

  • True (CORRECT)
  • False

Correct: The Azure portal updates continuously and requires no downtime for maintenance activities. This configuration makes the Azure portal resilient to individual datacenter failures and avoids network slowdowns by being close to users.

5. True or False? Serverless computing enables developers to build applications faster by eliminating the need for them to manage infrastructure.

  • True (CORRECT)
  • False

Correct: 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.

6. True or False?

The Azure Marketplace is a service on Azure specific to Microsoft Products.

  • True
  • False (CORRECT)

Correct: The Azure Marketplace is a service on Azure that helps connect end-users with Microsoft partners, independent software vendors (ISVs), and start-ups that are offering solutions and services which are optimized to run on Azure. 

Azure Marketplace allows customers to find, try, purchase, and provision applications and services from hundreds of leading service providers, all certified to run on Azure.

7. Azure provides four main types of storage services. One of these services Azure Blob storage provides for which of the following.

  • Storage service for very large objects such as video files or bitmaps. (CORRECT)
  • A data store for queuing and reliably delivering messages between applications.
  • File shares that you can access and manage like a file server.
  • A NoSQL store that hosts unstructured data independent of any schema

Correct: Azure Blob storage provides storage service for very large objects such as video files or bitmaps.

8. Which tool can you use to assist in creating custom Dashboards that will help in graphically organizing your resources in Azure?

  • Azure Portal (CORRECT)
  • Azure Marketplace

Correct: With the Azure portal, you can build, manage, and monitor everything from simple web apps to complex cloud deployments. Create custom dashboards for an organized view of resources and configure accessibility options for an optimal experience.

9. True or False?

To create and use Azure services, you need an Azure subscription.

  • True (CORRECT)
  • False

Correct: To create and use Azure services, you need an Azure subscription. 

10. Cloud computing provides computing services over the internet using a pay-as-you-go pricing model. With this model you typically only pay for the cloud services you use. Which of the following are benefits of the pay-as-you-go pricing model?

Select all that apply.

  • Lower operating costs. (CORRECT)
  • You can run your infrastructure more efficiently. (CORRECT)
  • You can scale as your business needs to change. (CORRECT)

Correct: That’s partially correct. One feature of Cloud services is that you typically pay only for cloud services you use, which helps you lower your operating costs.

Correct: That’s partially correct. One feature of Cloud services is that you can run your infrastructure more efficiently, and scale as your business needs change.

Correct: That’s partially correct. One feature of Cloud services is that you can scale as your business needs change.

Which Azure solution would best suit your business goal?

  • Azure Portal
  • Azure Marketplace (CORRECT)
  • Azure Virtual Machines

Correct: In the Azure Marketplace you can find, try, buy, and deploy the software and services you need to build new solutions and manage your cloud infrastructure. You can provision end-to-end solutions quickly and reliably, hosted in your own Azure environment.
