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
- Two Databases
- 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).
