Basically, it's a strategy behind building infrastructure that scales:
1. Containerization
↳ Package applications with all dependencies
↳ Ensure consistent behavior across environments
↳ Docker simplifies build, ship, and run workflows
↳ Enables microservices architecture
↳ Perfect for DevOps practices
2. Container Orchestration
↳ Kubernetes leads the way here
↳ Automates container deployment & scaling
↳ Handles load balancing
↳ Manages container health
↳ Enables zero-downtime deployments
↳ Supports multi-cloud deployments
3. Infrastructure as Code (IaC)
↳ Terraform for multi-cloud provisioning
↳ CloudFormation for AWS-specific workloads
↳ Ansible for configuration management
↳ Version control your infrastructure
↳ Test before deployment
↳ Implement infrastructure CI/CD
↳ Maintain consistent environments
4. GitOps Workflow (not in this sheet)
↳ Git as single source of truth
↳ Automated infrastructure updates
↳ Pull-based deployments
↳ Built-in audit trail
↳ Easy rollbacks when needed
↳ Improved security & compliance
Why this matters?
→ Improved availability and scalability
→ Consistent deployments
→ Optimized costs
→ Minimal human error
The key thing is, you treat infrastructure like code, and I mean literally -
Making it versionable, testable, and reusable!
