In this article we will analyze what Microsoft's cloud service offers us in terms of infrastructure. By using Azure we can transfer our on-premise systems to the Cloud or even go to some hybrid solution, where our on-premise systems will have a part of them in Azure. So it is very important to know how we will set up our infrastructure step by step.<\/p>\n\n\n\n

A typical infrastructure in Visio visualization looks something like this:<\/p>\n\n\n\n

But let's see what the Azure service icons mean.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

First of all we need a subscription, this is called subscription <\/strong>and it is essentially our wallet. All charges are made through there.<\/p>\n\n\n\n

The Azure <\/strong>mainly works with the model pay as you go<\/strong> and we pay for the resources we consume per month. We can also pay for time in advance for a lower cost.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

After creating our subscription, if we don't already have one, one is created for us Azure Tenant<\/strong> with our account at Azure Active Directory<\/strong>. From there we can create new users, set role-level permissions (RBAC<\/strong>), user security and more.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Then we have the resource groups<\/strong>, are essentially buckets for separating resources, i.e. they contain all the following that we will analyze such as Virtual Machines, Storages, Vnets, etc. <\/p>\n\n\n\n

Their use makes it easier to distinguish productive from test and development systems. We can have different administrators (Contributors<\/strong>) and track the cost of each resource group separately.<\/p>\n\n\n

We don't need to say much here Virtual machines<\/strong> in Azure they are created easily and quickly, they have many images to choose from and with many variations of pre-installed applications, e.g. Windows Server 2019 with SQL Server 2019 Enterprise. We also have to select the resources of the Server that will host it.<\/p>\n\n\n\n

The options we have:<\/p>\n\n\n\n
