  • What is Cloud Computing.
  • Type of Azure Cloud.
  • Azure Key Concept.
  • Azure Domain Concept.
  • Traditional vs. Azure Cloud Model.
  • Applications of Azure.
  • Advantages of Azure.
  • Disadvantages of Azure.



1- What is Cloud Computing.


Cloud Computing is a term used to refer to storing and accessing data over the Internet. It does not store any data on your personal computer hard disk. In cloud computing, you access data from a remote server.

Cloud Computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, it may be designated an edge server. [Ref.]


2- Type of Azure Cloud.


There are 3 type of Azure Cloud.

PAAS [PLATFORM AS A SERVICE].
SAAS [SOFTWARE AS A SERVICE].
IAAS  [INFRASTRUCTURE AS A SERVICE].

1:- PAAS [PLATFORM AS A SERVICE]


Platform as a Service (PaaS) platform-based service is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. 


Platform as a Service (PaaS)

Advantages

1. The total cost is low because resources are allocated on demand and servers are automatically added or subtracted.

2. Azure is less vulnerable because servers are automatically checked for all known security issues.

3. The entire process is not visible to the developer, so there is no risk of data breech.

Disadvantages

1. Portability issues can occur when you use Paas services.

2. Azure can have a different environment, so the application needs to be customized accordingly.

2:- SAAS [SOFTWARE AS A SERVICE]

Software as a Service (SaaS) is a software delivery model in which a third-party provider hosts applications and makes them available to customers on the Internet. SaaS is one of the three main categories of cloud computing, with infrastructure as a service (IaaS) and platform as a service (PaaS).

Software as a Service (SaaS)


3:- IAAS [INFRASTRUCTURE AS A SERVICE]

Infrastructure as a Service (IaaS) is a service model that distributes computer infrastructure on an outsourced basis to support enterprise operations. Typically, IaaS provides hardware, storage, server and data center space or network components; It may also include software.


Infrastructure as a Service (IaaS) is also known as Hardware as a Service (HaaS).

Advantages

1. It provides efficient design and time portability.

2. This is appropriate for an application that needs full control.

3. The obvious advantage of IAAS is that it frees you from the worries of installing multiple physical or virtual machines.

4. Helps you to access, monitor and manage datacenters.

Disadvantages

1. Too many security risks from unexpected servers.

2. Some companies have defined procedures for testing and updating server vulnerabilities. This cannot be done with Azure.


3- Azure Key Concept


Concept Name
Description
Datacentre
In Azure, you can deploy your applications to various data centres around the world. Therefore, it is advisable to choose an area that is close to most of your customers. This helps you reduce latency in network requests.
Azure Portal
Azure portal is a web-based application that can be used to create, manage and extract Azure resources and services. It is located at https://portal.azure.com.
Resources
Azure resources are a personal computer, networking data, or app hosting services that charge individually. Some common resources are virtual machines (VMs), storage accounts, or SQL databases.
Automation
Azure allows you to automate the process of creating, managing, and deleting resources using PowerShell or Azure command-line interface (CLI).
Azure PowerShell
PowerShell is a set of modules that provide cmdlets to manage Azure. In most cases, you can use the cmdlets command for the tasks you are performing in the Azure portal.
Azure Command-Line Interface (CLI)
Azure CLI is a tool you can use to create, manage, and delete Azure resources from the command line.
Resource Groups
An Azure resource group is a container that holds related resources for an Azure solution. This may include each resource or only resources you want to manage.
Regions
Azure is a global cloud platform available in various regions around the world. When you request a service, application, or VM in Azure, you are first asked to specify a region. The selected area represents the datacentre where your application runs.
Resource Manager Templates
It is a JSON that defines one or more resources to be deployed in a resource group. It also establishes dependencies between deployed resources.
REST APIs
Azure is built on a set of REST APIs that help you perform the same operations that you do in Azure Portal Ul. This allows your Azure resources and apps to be manipulated through any third party software application.
