Multi-Cloud Management: Tek Bir Platformdan Tüm Cloud'ları Yönetin

Multi-Cloud Management: Tek Bir Platformdan Tüm Cloud'ları Yönetin

AWS + Azure + GCP + On-premise hepsi farklı console. Multi-cloud chaos. Unified management platform ile control geri kazanın.

Neden Multi-Cloud?

• Vendor Lock-in Avoid: Tek cloud'a bağımlı kalma
• Best-of-Breed: AWS storage, GCP AI, Azure AD
• Geographic Coverage: Farklı regionlar, compliance
• Cost Optimization: Cloud arbitrage
• Disaster Recovery: Cloud failover

Challenges

1. Complexity: Farklı APIs, terminoloji
2. Cost Visibility: Unified billing yok
3. Security: Multiple IAM systems
4. Networking: Cross-cloud connectivity
5. Skills: Team AWS, Azure, GCP bilmeli

Management Tools

1. Terraform (IaC)

# Unified infrastructure code
provider "aws" {}
provider "azurerm" {}
provider "google" {}

# AWS resources
resource "aws_instance" "web" {
  # ...
}

# Azure resources
resource "azurerm_virtual_machine" "db" {
  # ...
}

2. Kubernetes (Workload Orchestration)

Kubernetes AWS EKS, Azure AKS, GCP GKE'de aynı. Workload portability.

3. Rancher (Cluster Management)

Tüm Kubernetes cluster'ları tek dashboard. AWS, Azure, GCP, on-prem hepsi.

4. CloudHealth/CloudCheckr (FinOps)

Unified cost dashboard. AWS + Azure + GCP spending tek yerde.

Network Architecture

Hub-Spoke Model:

• Central hub (on-prem or cloud)
• Spokes: AWS VPC, Azure VNet, GCP VPC
• VPN/Direct Connect connections
• Centralized security, monitoring

Security & Compliance

• Centralized IAM: Okta/Azure AD federation
• Policy as Code: OPA (Open Policy Agent)
• Unified Logging: Splunk, Elastic
• Security Posture: Prisma Cloud, Lacework

Cost Optimization

Strategies:

1. Workload placement optimization (cheapest cloud)
2. Reserved instances cross-cloud comparison
3. Spot instances (AWS), Low-priority VMs (Azure)
4. Data transfer cost minimization
5. Rightsizing recommendations

Best Practices

1. Start with 2 clouds max (complexity management)
2. Standardize on Kubernetes (portability)
3. Use managed services carefully (lock-in risk)
4. Centralized monitoring (Prometheus, Grafana)
5. FinOps from day 1 (cost tracking)
6. Team training (multi-cloud skills)

Sonuç

Multi-cloud complexity ama flexibility kazanç. Doğru tools ile manageable. Devups multi-cloud setup.
