=========================
What is Infrastructure ?
=========================

=> Resources required to run the business

school business : building + classrooms
				  tables
				  chairs
				  boards
				  computers
				  projectors


software company : building
				   power
				   network
				   meeting rooms
				   tables
				   chairs
				   machiness
				   databases
				   security
				   monitoring


=> purchase and manage all the resource required to run our business. That is called as "On Prem Infrastructure"

		=> Lot of money required
		=> Lot of time we need spend

		=> security
		=> scalability
		=> availability
		=> network issues
		=> power issues
		=> disaster recovery		


=> To overcome the problems of on-prem infrastructure, companies are using cloud infrastructure.		


Cloud infrastructure : take resources for rent

===========================
What is Cloud Computing ?
===========================

=> Providing IT infrastructure thru internet on demand basis is called as Cloud Computing.

=> Cloud computing works based on 'Pay as you go' model.

=> We have several advantages with cloud computing

		1) Low cost
		2) pay as you go
		3) scalability
		4) availability
		5) reliability
		6) security
		7) unmited storage
		8) backup

================
Cloud Provider	
================

=> The company which is providing cloud infrastructure is called as cloud provider.

Ex : 

Amazon
Google
Microsoft
salesforce
oracle
ibm
ali baba
Digital Ocean

============
What is AWS	
============

=> Amazon Webservices

=> AWS is a cloud platform managing by amazon company

=> AWS cloud started in 2006

=> AWS providing cloud infrastructure based on "pay as you go" model

=> 190+ countries using aws cloud services.

=> AWS providing cloud resources in the world using global infrastructure concept.

=> AWS maintaing global infrastructure by using regions and availabilty zones concept.

	Region = geographical location

	A.Z = data center (server room)


36 launched Regions
114 Availability Zones
