Migration and modernization path
1. Rehost
Rehost - Monolithic application on IaaS
> Redeploy as is on the Cloud
> Commonly know as "lift and shift"
> Very little or no modification
> Quick and easy cloud migration
> Minimal application disruption
Re-Hots with IaaS automationInfrastructure as Code (IaC) with CI/CD Pipeline
Terraform
CloudFormation
ARM
Ansible
Puppet
GitHub
Jenkins

2. Refactor
Refactor - Containerize monolithic application
> Increase portability
> Easier to deploy
> Better cloud efficiency
> Platform independence
Orchestrate your container
> Declarative model
> Scaling
> Resources scheduling
> Fast deployment
> No lock-in
