Creating first simple AWS EC2 Instance
In this post we are going to discuss how to create our first AWS EC2 instance. If we compare a EC2 instances with our traditional infrastructure then it can be understood as a server.
Steps to create an EC2 instance
Login to your AWS management console and follow the below steps to proceed further.
In next blog we will learn how to connect to an EC2 instance using putty.

Creating a Postgres(RDS) on Amazon Web Services (AWS)
In this post I am going to share how can we configure a Postgres Database using RDS service on Amazon Web Services.
I would be using the AWS free tier for this setup.
Once we login to AWS account go to Services Tab and select RDS.
Click on Launch New DB Instance and follow the below steps to proceed further.
Connecting to Postgres Database using the pgadmin4 tool.

Creating a Oracle Relation Database Service(RDS) on Amazon Web Services (AWS)
AWS is one of the major giants in Cloud technology today. In this post we will learn how to create a Relation Database Service on AWS.
Select the instances Tab and Select Launch DB Instance
Oracle Enterprise Edition is included in free-tier. Select Oracle EE.
Fill the details as per you need.
DB instance creation will take some time.
Click on the instance name to see the details.
Select Instance Actions and select See Details for check further details.
To create a RDS service you should register on AWS and create a account. Amazon provide a free tier account which can be used for 12 months and has sufficient free services available to practise.
I am also using a free-tier AWS account for writing this post.
Once we login to AWS account go to Services Tab and select RDS.
Select the instances Tab and Select Launch DB Instance
Oracle Enterprise Edition is included in free-tier. Select Oracle EE.
Fill the details as per you need.
DB instance creation will take some time.
Once the instance is created it will be available.
Click on the instance name to see the details.
Select Instance Actions and select See Details for check further details.

Installation of Oracle 11g Database on Oracle Virtual Box
In this post we will look into steps for installation of Oracle 11g database on Virtual Box.
We need to download Oracle 11g software for Linux from Oracle site.
The installation will be done on Oracle Virtual box having Oracle Enterprise Linux. Detailed steps for installation of Virtual Box and OEL is posted earlier. Please refer Oracle Virtual Box Installation for detailed steps.
Only we need to make sure we defined hardisk and RAM to virtual machine as per your need.
I have given 50 GB hard disk and 2 GB RAM to my virtual machine which will be used for the installation.
The layout of the file system is as below:
Once the machine is prepared will proceed with database installation and creation.
/u01 -- will be used for Oracle Home
/datatop -- will be used for datafiles
Install the pre-required rpm's for oracle database installation using yum.This will also create a oracle OS user that will be used for installing the database.
