Deploying Applications into Virtual Machines

Installing Some Java application on IaaS (EC2)

• Lets create an EC2 instance with ubuntu os
• executed the following commands

sudo apt update
sudo apt install openjdk-11-jdk -y
wget https://referenceapplicationskhaja.s3.us-west-2.amazonaws.com/spring-petclinic-2.4.2.jar
java -jar spring-petclinic-2.4.2.jar

* In this approach:
* OS updates: our responsibility
* Platform Update (JDK): Our responsibility
* Application Update (New Version): Our responsiblity

Installing Some Java application on PaaS (Elastic Beanstalk)

• In Elastic Beanstalk we are responsible for Application Versions
• Os updates and platform updates are managed by AWS
  
  
• Note: If you want any custom platform, it is recommended to use Docker.
