What is Microsoft Azure?


Azure is a cloud platform which was launched by Microsoft in February 2010. Azure platform provide everything as a service. There are 100+ cloud services provided by Microsoft.

Main services: Infrastructure, Platform, Software (IPS)

Azure Compute Services: Azure virtual machine,  Azure virtual desktop,  Azure container instance , Azure app services,  Azure functions( Run code when in need means Event based code running means).

Azure Networking Services: Azure express route, Azure DNS

Azure Storage Services: Container storage(blob),Disk storage, Azure files. these services falls under (Storage Account like a supermarket)


Categories Azure Clouds Services

Broadly There are Three Types of cloud service categories by Microsoft Azure :

1. Platform as a service (PaaS) : For Developers

Deployment and management of your services. Most common PaaS services are(Beanstalk, Heroku, Google App Engine).

Elastic Beanstalk is a platform as a service (PaaS) for developing  offered by Amazon Web Services for deploying applications .

Elastic Beanstalk is a service for deploying and scaling web applications and services. Upload your code and Elastic Beanstalk automatically handles the deployment—from capacity provisioning, load balancing, and auto scaling to application health monitoring.

Heroku is a platform as a service (PaaS) that enables developers to build, run, and operate applications entirely in the cloud.

Google App Engine is platform as a service (PaaS) for developing and hosting web applications offered by Google Cloud Platform(GCP) in Google-managed data centers.

Example: You Don't need to worry about updating windows, required s/w to be installed  its all Microsoft responsibility to be available for you. 

Create Web App  on  azure portal is example of PaaS.

2. Software as a service (SaaS):  For Customers

A Product that is run and managed by cloud company. Most common SaaS services are(Salesforce, Gmail, office365). its kind a ready to use service.

Marketplace  on  azure portal is example of SaaS.


3. Infrastructure as a service (IaaS): For Administrator

There is full control over Operating System(VM in case of cloud). Most common IaaS services are (Compute, Storage, Networking, Databases) by cloud service providers like (AWS, Azure cloud ,Google cloud platform(GCP)).

Example: suppose if you have a java developer and you required java ,tomcat server and other related tool to be installed first on OS . In LaaS  its your responsibility as per your requirement to be installed all software. Microsoft will not responsible for this. 

Azure cloud job types?

  • Developer
  • Solution architect
  • Administrator

Benefits of Cloud

1. High availability: Cloud almost 99.9% out of  100% available. handling load by using  load balancer.

2. Scalable: Manually Adding or removing the capacity to meet varying load, that is Scalability.

There are 3 types of Scalability

      1. Vertical Scaling: Adding or removing the capacity into existing VM called Vertical Scaling.

      2. Horizontal Scaling: Adding or removing more helper VM's  based on capacity called Vertical Scaling.

3. Elastic : Automatically Adding or removing the capacity to meet varying load, that is Elasticity.

4. Reliable: continue to operate even in case of failure (Disaster recovery and backup). 

5. Predictability:

6. Secure:

7. Governance:

8. Manageability:

Types of  cloud

There are three types of cloud.

1. Private

Private cloud, single organization. Only your employees can use it.

private cloud simply means data center will be maintained by a single organization. Please note this is a keyword for your certification.

Non Technical Example: private car

Technical Example: VPN

2. Public

You simply rent out the resources maintained by the third party provider. its kind a self service Organizations will pay only for what they use

Non Technical Example: OLA , UBER car

Technical Example :Azure,  AWS, google cloud

3. Hybrid

provide the most flexibility.


Azure resource 

Whatever you created in azure cloud by using azure portal is term as azure resource.

In Azure, a resource is an entity managed by Azure. Virtual machines, virtual networks, and storage accounts are all examples of Azure resources.

Azure resource group

collection of related resource is term as resource group or we can say logical grouping of azure resources is called as resource group.

Example1: your carry bag is kind a resource group .in carry bas you can contain other necessary items what you want to carry.

Eample2: Grandfather ->Parent ->Child(One to many relationship we can say)

Azure Resource Manager

Azure Resource Manager connects to Microsoft (Azure resource provider) for manage the services. 


Azure Virtual Machine  vs Azure Virtual Desktop

1 Azure Virtual Machine Azure Virtual Desktop
1. 1 VM = 1 user  One: One Relationship  Desktop virtualization can handle many user at once ie.1VD = many user One : Many Relationship 
2. Require client to connect  like RD or SSH or  based on O.S  It is browser based 

Azure container services

The services which are used to run the container(Software package) is called Azure container services.

Azure container Instances

As a PaaS which helps to  run a container in azure  server directly without need to VM or additional service.

Azure Kubernetes Services

Microsoft Azure pricing calculator: On azure cloud we know  mostly services  provided by Microsoft are paid So there is a tool called Microsoft Azure pricing calculator with the help of which we can estimate the price before purchase. Its a free toll for usage.

Marketplace: is Microsoft Store like google play store and apple I store


Governance: Basically Azure policy. Microsoft defines some rules on azure cloud.  There are almost 1600 plus rules on azure portal that you have to follow.

Compliance: means conforming to a rule, such as a policy or law.
