Scenario 1: Migrating one server to Azure

• The steps which we follow to migrate one server or from other clouds is almost the same.
• The supported operating systems are
  • Linux
  • Windows
    
• Source For migration: (Simulated)
  • I will be creating an ubuntu 20.04 LTS vm in (AWS/Azure/GCP/Vmware)
• In the source we will be installing some sample application (Spring petclinic)

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

• Now navigate to the publicip on port 8080
  

Order of Migration

• Consider the below architecture
  
• When we migrate, we follow the migration from least dependent server to the most dependent server
• In the above case, we should be migrating in the following order
  1. database server
  2. application/middle ware
  3. webserver
