Azure Stack, Microsoft Azure is a cloud computing service by Microsoft (formerly known with a name – Windows Azure) for building, deploying, testing applications/services via a global network of data centres which are managed by Microsoft itself.
There is Platform as a Service (PaaS), Software as a Service (SaaS) and Infrastructure as a Service (IaaS) service offerings provided by Microsoft in this regard which support many programming languages that are available in the market as on today.
What is Azure Stack?
Microsoft’s Azure Stack is an on-premises variant of its public cloud offerings that are deemed important for pros in the market for one simple reason – that it gives its customers ways and means to use the most familiar cloud platform without pushing their specific sensitive data into the multi-tenant environments.
Azure Stack is a software that has been announced by Microsoft which is certified to run on a premium list of partners’ hardware and is intended to be a look-alike of Microsoft’s Azure public cloud.
One other interesting feature that we might have to take a note of, is that no other competitor to Microsoft Azure has anything like Azure Stack – considering the competitors like Amazon Web Services (AWS) and Google Cloud.
Microsoft can be coined as the first of the three biggies in the Iaas (Infrastructure as a Service) vendors that provide a hybrid cloud platform constituting the on-premises hardware and the bundled software with similar software management tools as observed in the Azure Public Cloud offerings.
Azure Stack was announced in the later months of 2015 and is made available to the customers to consume their services by the fall of 2015. Microsoft Azure Stack GA is right around the corner for its release that somewhere in mid-2017.

Microsoft has started providing various combinations of offerings for Azure Stack which are detailed as below:
A software-only Azure Stack Development Kit (ASDK) is made available for proof of concepts purposes
A combined hardware-software offering named Azure Stack Integrated System with the hardware being provided by any of the trio (DELL EMC, HPE or Lenovo) and a necessary license for the Azure Stack software to run on top of the hardware that is purchased.
Microsoft has its offering in two major ways to purchase the Azure Stack licensed software, one by “pay as you go” model and the other “pay as you use” model where the usage of the infrastructure and software will be charged.
What are Azure Stack’s Services?
Azure Stack is comprised of two components which constitute the whole product in itself
The infrastructure that is sold to the customers from any one of the Microsoft’s certified partners like Dell EMC, HPE, and Lenovo
