==================
Elastic Beanstack
==================

=> End to end web application management service.

=> It provides platform as a service (PaaS).

=> AWS will provide ready made platform to run our application when we go for Beanstack.

Note: Upload your code and run your application, aws will take care of infrastructure and platform to run your application.

==================
Web Application
==================

=> The application which runs in the server is called as web application.

=> Web application works based on client-server architecture.
		
=> Server is a software which is used to run our application.

	Ex: httpd, tomcat, weblogic, web sphere, jboss, IIS...

=> Client is a software which is used to send the request to server and get response from server.		

	Ex: browsers (chrome, firefox....)

======================
Web application types
======================

1) Static web applications

2) Dynamic web application	

=======================
Static website hosting
=======================

=> We can deploy static website very easily with below options

1) Using httpd server

2) Using s3 bucket

=======================================
Dynamic Web App - Deployment process
=======================================

=> To develop dynamic web applications we will use below technologies

	Ex: Java, Python, Dot Net, Node JS, PHP etc...

=> We need to perform below tasks to deploy one dynamic web application in aws cloud.

Step-1) Create Network (VPC, Subnets, RT, IGW, NATGW)	

Step-2) Create EC2 Instances

Step-3) Install Required softwares to run application

	Ex: Java, Tomcat...

Step-4) Create Target Group and Load Balancer

Step-5) Setup Auto Scaling Group

Step-6) Deploy our application code	

Note: We are responsible for "infra setup + platform setup + app deployment"

### Note: When we use AWS Elastic Beanstack service then AWS will take care of first 5 steps, we just need to upload our code.

================================
Elastic Beanstack Pricing Model
================================

=> No additional charges for elastic bean stack.

=> We need to pay the amount for the resources which are created by bean stack.
	
	Ex: EC2 instances, S3 buckets, LBR, ASG etc...


================================
Lab Task on Elastic Beanstack 
================================

Step-1) Create IAM Role with below 3 policies

		- AWSElasticBeanstalkMulticontainerDocker
		- AWSElasticBeanstalkWebTier
		- AWSElasticBeanstalkWorkerTier

	Ex : Role Name : ashokit_beanstack_role		

Step-2) Create Application using Beanstack

Step-3) Create Environment for the application by choosing required Runtime.

	Ex: Java or Python or Dot Net

Note: Once environment is created it will generate DNS to access our application.


====================================
Uploading Java SpringBoot Web App 
====================================

=> Take jar file of java springboot web app

=> Go to Elastic Beanstack environment and upload your jar and give version number for your application

	Ex: v1.0

=> Go To enviornment Properties and set SERVER_PORT as 5000

		Ex : SERVER_PORT = 5000	

	- Select Environment
	- Go to Configuration
	- Edit "Updates, monitoring, and logging" option
	- Set Environment Property	and apply	

=> After environment got re-started, we can access our application by using DNS url.
