An Elastic IP address is a Public IP that you may allocate to your account.An Elastic IP address is an static IP address which is designed for the purpose of the dynamic cloud computing. An Elastic IP address is associate with the AWS account. It is a public IP address, that can be accessed from the Internet.
when ever an instance is created and if it does not have the public IP address we can associate that instance with an Elastic IP and enable the communication between the internet.
In this lab we are going to use an Elastic IP’s in Amazon. we are going to perform
1)Allocate the IP address to the instance
2)Associate the IP address to the instance
3)re-associate with the replicated server ‘webserver02’
in order to associate an Ip to an instanec primarily it must be added to the aws accout of the individuals.once the association of the elastic IP address has been doone with the instance,its public IPV4 address is released bak into the Anazons pool of public Ipv4 addresses.once the association of elastic IP has done wthe the instance its public dns hostname will be changed t the elastic Ip.first we have to create a new elastic IP address and it has to be associated with the main web server
Go to the EC2 dashboard in the services Menu in the AWS Management Console. Click ‘Allocate New Address’ and next page, Click “Allocate”. An IP address will be allocated as shown below
this is my elastic Ip
now we have to associate newly created Elastic IP address with the instance “WebServer5”. Go to the “Action” menu. Select “Associate Address” and click on it.
Now associate the instance with the Elastic IP. choose Instance Select the instance from the top down list and private IP. Then click on “Associate“
the instance and its IP now will be associated with the Elastic IP Address. as shown below
now open the browser from the local computer . Run the dinostore5 website. we can see that running from the public DNS address. Now replace the public DNS address with the Elastic IP Address.It will work successfully opening the web page as shown below
now iam going to associate the Elastic IP address with the AMI instance “webserver02″. Go to the Action menu from the Elastic IP page. Choose the “associate address” and click on it. 
now give the instance details that is the instance of “webserver02′
once it has successfully created it will be displayed as below.
It will display the below web page 
by this lab we can host the web page with the elastic IP address. I did not encountered any problem during this lab. hoping you too wont face any problem
Thank You……………………..!
