Understanding Azure Cloud Service Mannequin And Azure Compute Companies

On this article we are going to perceive the Azure cloud service Mannequin and varied compute providers provided by the Azure Platform.


We can even take a deep dive to know the variations between these providers by way of value, upkeep and scalability.


It will assist us to pick out the appropriate Azure service as per our enterprise want.


Earlier than beginning with Azure Cloud service mannequin let’s attempt to perceive why we would wish a cloud service after we have already got on premise arrange in our group 


Why do we want Cloud Companies?


Microsoft Azure platform offers all or lots of the under options by default or out of the field.



  • Ablity of system to scale by including or eradicating sources.
  • Assets might be like all reosuces inculding VM, database storage and extra.


  •  Elastcity is the ablity of a system to scale dynamically.


  • The ablity to react shortly and allocate and dellocate sources in a really brief time.
  • Within the on premise world requesting useful resource and allocation may take weeks to months of time relying upon the useful resource.
  • Within the cloud,  useful resource spin up would occur in minutes and at maxium it will take a couple of hours for heavy sources.

 Fault Tolerance

  •  Ablity of system to stay up and working throughout part and repair failures 
  •  Main Azure cloud providers have in-built fault tolerance. 

Catastrophe restoration

  • Catastrophe restoration is the power of a system to recuperate from an occasion that has taken down the service
  • Catastrophe restoration might be simply set by setting replication in differnet areas.

Excessive Availability 

  • Availability is a measure of system uptime . 

Consumption primarily based pricing mannequin in Azure


A cloud platform permits for a consumption-based pricing mannequin.


Beneath are the important thing advantages of this mannequin. 

  • There isn’t a upfront value.
  • Allocate sources as per your want. 
  • You’ll begin paying solely once you would begin utilizing the sources.
  • There isn’t a wastage of sources.
  • Assets might be simply dellocated after we dont want them.
  •  A number of pricing componenets per service primarily based on compute energy, networking and storage.
  •  Very granular utilization measurement.

 Price Administration service offers quick access to see a consumption primarily based pricing mannequin




Now that now we have understood a few of the advantages of utilizing a cloud platfrom and the way consumption primarily based pricing mannequin works we are going to now deal with Azure Service Fashions.


Azure provides three service Fashions

  • Iaas (Infrastruture as a service)
  • PaaS (Platform as a service)
  • SaaS (Software program as a service)



  • All layers associated to {hardware} and virtualization.


  • Working system, middleware and runtime
  • system and configuration required to run the software program.

Software program layer 

Iaas (Infrastruture as a service)

  • Cloud supplier manages infrastruture and consumer manages platform and software program. 

Use Case

  • Migration of labor hundreds from on premise to cloud.
  • Raise and shift mannequin 
  • VM Companies 

PaaS (Platform as a service)

  • Cloud supplier manages infrastruture and platform whereas consumer manages solely software and knowledge.

 Use Case

  •  This mannequin is used for bulding cloud prepared purposes
  •  App service, Azure SQL perform apps.

SaaS (Software program as a service)

  • Cloud supplier manages everthing. 

Use Case


Outlook, Skype, One Drive 


Now that now we have understood Azure Service Mannequin let’s take a deep dive into totally different Compute service choices by Azure 


Azure Compute service


Let’s first perceive what a compute service is.


Compute providers are providers that permit you to construct and deploy your software within the Cloud.


VM (Digital machines home windows and Linux) 

  • Virtualization in Azure cloud is finished by Azure VM.
  • VM is the a part of Iaas mannequin . 
  • Microsoft has ready VM Photographs in Azure market palace. 
  • We will use predined photographs or construct new VM primarily based on our customized picture
  • That is a part of IaaS providing by Azure 



  • Whole management on working system and platform 
  • Greatest suited to raise and shift migration on premise to cloud with out redesign.


  • Excessive Upkeep 
  • No auto scaling

VM scale set

  •  Customized picture or Picture from azure retailer is routinely scaled throughout a number of VMs
  •  The load balancer redirects site visitors to the digital machines.
  •  The quantity of VM might be scaled routinely relying on software demand
  •  That is a part of IaaS providing by Azure


  • Constructed with auto scaling 


Aure container cases


Bundle software to create container picture and host in container occasion.


Azure container repository is straightforward storage the place we host our personal photographs


Easiest and quickest method to run containers in Azure.


PaaS providing by Azure.



  • Much less upkeep than VM
  • Lighter weight thanVM
  • Small and easy net purposes



No auto scalablity


4) Azure Kubernetes service 


Kubernetes in is an open supply conatiner orchestration platform


PaaS providing by Azure 


Extremely scalable and extremely customizable.


Container deployment on a number of nodes.




  • Excessive scalablity
  • Auto scaling 
  • Lighter than VM 
  • Extremely subtle


  • Most advanced to implement

App providers


Designed as enterpise grade net software service.


PaaS providing by Azure




  • Much less maintanance 
  • Medium scalablity
  • Auto scalablity



On this article, now we have realized concerning the want for cloud platforms and varied choices by Azure Cloud and totally different service fashions.
