  • Open port 80 from the security group of the Cloud9 EC2 instance

  • Get the cloud9 EC2 public instance IP address and test that you can access the website

Step 4: Create a MySQL RDS database instance

with the following specifications.

  • Create a db subnet group

  • Databasetype: MySQL

  • Template: Dev/Test

  • DBinstanceidentifier: Example - DB instance size: db.t3.micro

  • Storage type: General Purpose (SSD)

  • Allocatedstorage: 20GiB - Storageautoscaling: Enabled

  • Standbyinstance: Enabled

  • Virtualprivatecloud: ExampleVPC

  • Databaseauthenticationmethod: Passwordauthentication

  • Initialdatabasename: exampledb

  • Enhanced monitoring: Disabled

Step 5: Create an Application Load Balancer

  • Create target group

  • Create an auto scaling group

  • Lunch Web Instances in the private subnet

Step 6: Importing the data into the RDS database

_Importing the data into the RDS database instance from CLoud9 or by accessing the web instance via bastion host

  1. get the SQLDump file:

  2. connect to the RDS database, run this command:

mysql -u admin -p --host <rds-endpoint>
  1. Test that you can access the RDS DB
use exampledb;    
show tables;
  1. Import the data into the RDS database.
mysql -u admin -p exampledb --host <rds-endpoint>  < Countrydatadump.sql

Test the ALB

  • Test data was imported
 use exampledb;    
show tables; 
select * from countrydata_final;

Step 7: Configure the system parameters in Parameter Store Systems Manager

Add the following parameters to the Parameter Store and set the correct values:
