Migration of a Workload running in a Corporate Data Center to AWS using the Amazon EC2 and RDS service

In another project based on a real-world scenario, I acted as the Cloud Specialist responsible for migrating a workload running in a Corporate data center to AWS.
The application and database were migrated to AWS using the Lift & Shift (rehost) model, moving both application and database data.

I followed some migration steps: Planning (sizing, prerequisites, resource naming), Execution (resource provisioning, best practices), Go-live (validation test — Dry-run, final migration — Cutover), and Post Go-live (ensuring the operation of the application and user access).

In planning, we have to do the inventory of the on promise data center by listing all the different equipment on the data center and making the equivalencies on the cloud service (AWS)

On execution, we have to create the VPC, public and private subnet, internet gateway, EC2 instance, and RDS and configure the ports necessary for the connectivity, such as ports 22, 8080, and 3306.

After that, we installed and set up the packages and libraries for the app and DB connection.

On go live we ssh to the VM-EC2 and downloaded the application and the Dump file. Then, we connected to the MySQL server (AWS RDS) to create a DB wikidb and import data. After loading the application, we validate the migration.
