Problem Statement

• Our ficticious Organization:
  • name: Asquare info systems
  • Product: iEcommerce
  • Purpose: Any Organization can buy this project and host ecommerce applications
• This product is designed to work on any virtualized platform such as
  • VMWare
  • OpenStack
  • AWS
  • Azure
  • GCP
• Now Asquare info systems needs to have an apporach to deploy the iEcommerce applicatio into Customers Cloud/Virtual Environments
• Architecture of iECommerce
  
• Infra for iECommerce
  • Two networks with connectivity b/w them (same building, different buildings, cities, countries)
  • In Each network
    • Two Databases
      • mysql
      • RAM: 8 GB
      • cpus: 2
      • Disk: 10 TB
    • one File Store
      • Size: 10 TB
    • 3 Servers:
      • OS: Ubuntu 22.04
      • RAM: 16 GB
      • Cpus: 2
      • Disk: 50 GB
• Solution:
  • InfraProvisioning: This represents using Infrastructure as a Code and deploy to target environment

Understanding InfraProvisioning

• Analogy
  
  
• We using InfraProvisioing tools where we express our desired state about infrastructure as code.
• Terraform: Can create infra in almost all the virtual environments
• ARM Templates: Can create infra in Azure
• Cloudformation: Can create infra in AWS
• Infraprovisiong tools use IaC which are generally idempotent
• Idempotance is the property which states execution one time or multiple times leads to the same result.
• Reusability is extreemely simple and terraform can also handle multiple environments (Developer, QA, UAT/Staging/Production).
