Azure Classroom Series – 11/Jul/2021

Exploring

• Lets create a Ubuntu Server 20.04 with size Standard_B1s
• Select the necessary options and create the virtuam machine
• Lets download the template
• Overview of Templates
  • When we try to create any thing in Azure, Azure will create a template and deploy it.
  • The deployment of template leads to creation of resources
• Basic Idea behind templates:
  • When we want to do the same activity again, rather that reselecting the stuff from azure portal, we can deploy the template.
• Assume your application deployment has lot of vms and other azure resources, creating them manually for every environment will be difficult to create, so as a solution
  • We can create the reusable template and deploy this reusable template with different parameters for different environments.

Azure Resource Manager Templates

• So, to automate application deployments on Azure we should be able to create/modify the templates to suit to your application needs
• Skills to acquire
  • Understanding JSON
  • Writing ARM Template from scratch
  • Modify the existing ARM Templates
• ARM Templates can be deployed from
  • Portal
  • CLI/Powershell
  • API
• This gives us the flexibility to integrate the ARM Template deployment with any CI/CD tool.
• Azure has developed a Domain Specific language where we can use declarative syntax to deploy Azure resources which is called as Bicep

JSON

• Refer Here for the JSON and YAML Tutorial

• Json is all about writing the data in the form of name value pairs

• Here when we try to do this value can be of the following formats

  • text
  • number
  • true/false
  • list
  • complex i.e it has more name value pairs

• For doing this json has specific syntax

<name>: <value>

• string/text

'name' : 'QualityThought'

• number

'started': 2010
'age': 11

• boolean

'classroom': false
'online': true

• list

'courses': [ 'AWS', 'Azure', 'DevOps', 'Python', 'DataScience' ]

• complex or object

address: {
    'flatno': '209-B',
    'building': 'Nilgiri Block',
    'landmark': 'Ameerpet Metro'
}

• Academics json

{
	"schooling": {
		"name": "Bhartiya Vidya Bhavan",
		"academic percentage": 85.6
	},
	"intermediate": {
		"name" : "FITJEE",
		"academic percentage" : 94,
		"specialization": ["Maths", "Physics", "Chemistry"]
		
	},
	"graduation": {
		"name": "NIT",
		"academic percentage": 75,
		"specialization" : "Computer Science and Engieering",
		"degree": "B.Tech"
		
	}
}

• Json is generally stored in files with .json extension.
• JSON is widely used to represent data and is a common format in web applications.
